Novel biomimetic scaffold for tendon and ligament tissue engineering

2009 IEEE 35th Annual Northeast Bioengineering Conference, 2009

Each year, surgeons repair more than 300,000 injured tendon and ligament (T/L) tissues in the United States alone [1]. Unfortunately, current treatments are limited, resulting in a clinical need for regenerated T/L tissues. Electrospun nanofibers are favorable for tissue engineering applications due to their resemblance in fiber diameter and morphology to extracellular matrix. We propose to utilize this biomimetic feature ...

An innovative neuro-fuzzv modfu for predicting creep ofthf medial collateral ligament

Proceedings World Automation Congress, 2004., 2004

It is well established that progressive recruitment of the collagen fibres in the knee medial collateral ligament (MCL) leads to the non-linear toe-region of the ligament stress-strain curve. It has also been argued that fibre recruitment helps the ligament to lessen and resist creep. Minimal creep in ligaments allows maintaining joint equilibrium. This is especially important for the knee stability ...

  • Novel biomimetic scaffold for tendon and ligament tissue engineering

    Each year, surgeons repair more than 300,000 injured tendon and ligament (T/L) tissues in the United States alone [1]. Unfortunately, current treatments are limited, resulting in a clinical need for regenerated T/L tissues. Electrospun nanofibers are favorable for tissue engineering applications due to their resemblance in fiber diameter and morphology to extracellular matrix. We propose to utilize this biomimetic feature of nanofibers in the generation of scaffolds that also mimic the macrostructure of natural tissue. We hypothesize that scaffolds that recapitulate natural tissue structure over a range of dimensions will enhance natural tissue regeneration with progenitor cells. Here, we report on the fabrication and initial characterization of a novel biomimetic scaffold that begins to recapitulate the complex structure of a fascicle and endotenon of natural T/L. Electrospinning was employed to generate aligned nanofiber mats that were seeded with progenitor cells and subsequently assembled into a complex construct to represent a fascicle surrounded by the endotenon. The resulting scaffold physically resembled native T/L and demonstrated the ability to support progenitor cell attachment, viability, and proliferation. Currently, studies are underway to characterize the ability for these scaffolds to support and enhance progenitor cell differentiation toward the T/L lineage and demonstrate the use of these novel biomimetic scaffolds for T/L tissue engineering.

  • Holes Effects on RF MEMS Parallel Membranes Capacitors

    Parallel membrane RF MEMS capacitors are designed with small diameter holes in the top plate of capacitance due to fabrication process requirements for sacrificial layer removal and modification of dynamic behaviour of the structure. The impact of hole characteristics (size, pitch and ligament efficiency) on the component performance is not very well documented in current literature. Only rules of thumb are used in the design without giving much justification. This study explores and assesses the effect of larger holes with different pitches and ligament efficiencies in fixed top membrane by means of simulations with CoventorWare analyzer simulation software and practical probing tests conducted on specifically designed set of RF MEMS capacitors. The approach used in this study is by varying the RF capacitance with two different axis of comparison. The first being a set of MEMS capacitors having different sized holes of equal combined surface and the second having fixed number of holes with different diameters. The experimental results converge quite adequately with the designed and simulated results giving a clear performance trend and appropriate designer solution. The outcome of this paper improves the degree of freedom of the designer with respect to the manufacturing difficulties for sacrificial layer removal associated to better dynamics and RF performances of the components

  • An innovative neuro-fuzzv modfu for predicting creep ofthf medial collateral ligament

    It is well established that progressive recruitment of the collagen fibres in the knee medial collateral ligament (MCL) leads to the non-linear toe-region of the ligament stress-strain curve. It has also been argued that fibre recruitment helps the ligament to lessen and resist creep. Minimal creep in ligaments allows maintaining joint equilibrium. This is especially important for the knee stability in regular daily activities like walking or running where loading is repetitively applied to the joint over many cycles. Nevertheless, due to dependency of fibre recruitment on many factors affecting its behaviour, the level of recruitment of the collagen fibres is difficult to quantify using classical modeling techniques. We therefore developed a soft- computing algorithm to model creep of the knee MCL in two steps: first, the ill-defined fibre recruitment is quantified using the fuzzy systems. Second, the fibre recruitment is incorporated along with creep stress and creep time to model creep using a hybrid neuro-fuzzy system. The model is trained and tested using experimental database including creep tests and crimp image analysis. The model showed very promising results and confirmed the role of fibre recruitment in viscoelastic behaviour of the ligament.

  • Measuring knee compliance to facilitate post-op ligament rehabilitation

    Using novel sensor technology to monitor a knee's health, one can measure the state of a post-op patient's knee unobtrusively, quickly, and accurately. A pair of Inertial Measurement Units (IMU) is coupled with a modern microcontroller, with the goal of the project being to create a device to use in an office setting. The device provides a quantitative output that can be used for plotting ligament recovery over time without the use of x-rays, thereby allowing a physician to prescribe and dynamically modify a rehabilitation schedule based on the individual needs of the patient.

  • Biomechanical study of myringotomy through simple incision and drainage tube insertion

    This work presents a comparison study from the biomechanical point of view regarding myringotomy through incision and with tube insertion. Myringotomy is a procedure of draining the fluid from an ear affected by otitis media with effusion, a sickness very often found in children. For the study an already validated finite element model of the ear was used. Results show that stresses are higher in the case of tube insertion use. Such stresses of the eardrum can determine the occurrence of different histological changes that can lead to pathologies of the ear like local atrophy, myringosclerosis or even severe pathologies like cholesteatoma.

  • Development of biomimetical composite prosthetic ligaments using mechanically dissimilar materials

    Using high performance textile materials and novel designs, structures were developed which have the potential for mimicking the properties of natural anterior cruciate ligaments (ACLs). Six tubular braided structures capable of withstanding the loads encountered by ACL, were built. Elastomeric materials were incorporated as cores in order to give the devices the ability to recover from strains. Mechanical and viscoelastic properties of the devices were evaluated It was shown that the behavior of the devices at lower (physiological) loads was determined by the core material, while the behavior at high loads was determined by the braided sheath material. A comparison of the properties of the structures with those of the natural ACL showed that the appropriate load bearing, linear modulus and strain hardening behaviors had been realized; however, further work was needed to mimic the extensibility properties.

  • Tensile properties of human Achilles tendon

    There were three foci of this study. The first was a delineation of the effect of two variables on the tensile properties of human Achilles tendon, To that end, the values of the ultimate tensile strength, UTS, strain at the UTS point, /spl epsiv//sub max/ and tangent modulus of elasticity, E/sub T/, of cadaveric Achilles tendon were obtained as a function of (a) donor age (36 to 100 y), at a fired loading rate of 10 %/s; and (b) loading rate (for tendons from the 52to 67-year-old donor group). The second focus was the presentation of a suitable constitutive relation between the tensile stress, /spl sigma/, and the tensile strain, /spl epsiv/, for this tissue. The aim of these two foci was to provide information that will aid in the selection of Achilles tendon for the repair of ruptured Achilles tendons as well as anterior cruciate ligaments (ACLs). The third focus was, thus, a comparison of the tensile properties of Achilles tendon and patellar tendon, which is now widely used for the repair of ruptured ACLs. It was found that: (a) age exerts a marked effect on UTS, an insignificant one on /spl epsiv//sup max/ and a moderate one on E/sub T/; (b) a ten-fold increase in loading rate results In a moderate but insignificant increase in UTS, a significant decrease in /spl epsiv//sub max/, and a significant increase in E/sub T/; (c) a suitable constitutive relation is /spl sigma/=C/spl epsiv/exp[D/spl epsiv/+F/spl epsiv//sup 2/], with C, D, and F being material constants; and (d) the tensile properties of Achilles and patellar tendons have similar values.

  • Static and dynamic comparison of human cervical spinal ligaments

    Static and dynamic properties of each spinal element are essential to construct a mathematical model to predict the mechanism of spinal injury. However, there is a lack of experimental data on the biomechanical parameters of these components. This study was performed to acquire biomechanical information on human cervical spinal ligaments, namely, the ligamentum flavum and the anterior longitudinal ligament, at various load rates. 68 ligaments from C2-T1 were tested in situ at each spinal level in a specially designed frame. Uniaxial tension was applied at a constant displacement rate to failure. Information from this study indicates a significant degree of rate sensitivity to material properties such as ultimate strength and stiffness, increasing with loading rate.<<ETX>>

  • Biomechanical effect of ankle Kinesio taping on the ground impacts during the vertical jump landing

    The injuries in the lower limbs are common at the sports, and one of the most common injuries is ankle sprain. Kinesio taping is one of the useful treatments of ankle sprain. The objective of this study is to investigate the biomechanical effects of ankle Kinesio taping on ground impacts during the landing of vertical jump, and the effect of ankle Kinesio taping on vertical jump in functional instability. Two AMTI force plates and VICON motion analysis system were used to collect kinematic and kinetic data. The result of this study showed that the ankle Kinesio taping can reduce the functional instability group's time to ankle second peak ground reaction forces, and decrease the first peak vertical ground reaction forces and the integrated impulses after landing. There was no significant effect of ankle Kinesio taping on the biomechanical parameters of ground impact in the control group.
