A fiber-based surgical implant stabilized against fraying, includes a thermally crimped flat-knitted fabric of a biocompatible, optionally biodegradable, polymer material having a glass transition temperature or other thermally induced secondary conformational mobility threshold in the temperature range of from 20° C. to +170° C. Also disclosed is a corresponding fabric and methods of producing the implant and the fabric.

Provided is an implant for restoring the mobility of an articular end of a bone. The implant includes a framework having a first face and a second face opposite the first face, the framework is defined by a plurality of free volumes formed by a grating, where the grating includes a first series of bars extending through the framework from the first face to the second face, and a second series of bars extending through the framework from the first face to the second face, wherein the second series of bars are parallel to one another, and spaced apart in pairs, where the bars have ends along the second face that are bevelled.

A implant delivery system for securing an implant to an anchor. The implant delivery system includes a driver including a shaft, a biasing body having a first end region configured to engage said driver and a second end region configured to engage a portion of an implant, and a suture extending between the anchor and the shaft of the driver. The driver may be rotated to reduce the length of the suture between the driver and the anchor and generate a biasing force urging the implant into engagement with the anchor. The biasing force is substantially not transmitted to the bone.

The present invention aims to provide a tissue regeneration substrate excellent in penetrability to cells as well as capable of effectively preventing cell leakage from the tissue regeneration substrate to accelerate tissue regeneration; and a method of producing the tissue regeneration substrate. The present invention relates to a tissue regeneration substrate including: a nonwoven fabric made of a bioabsorbable material, the tissue regeneration substrate having a laminated structure in which a layer containing a nonwoven fabric having an average pore size of 20 to 50 μm and a layer containing a nonwoven fabric having an average pore size of 5 to 20 μm are integrated.

An implant for repairing a cartilage defect comprising a first layer and a second layer. The first layer comprises a membrane-like structure and the second layer comprises a sponge-like structure with directional and/or interconnected pores. The first layer is facing the synovial space and the second layer is located towards bone.

A prosthetic device for use as an artificial meniscus is disclosed. The prosthetic device restores stress distribution, stability, and function to the knee joint after removal of the damaged natural meniscus. In some embodiments, the prosthetic device includes an anti-migration feature that inhibits extreme movement within the joint while permitting free floating over a significant range. In one aspect, the anti-migration feature is an enlarged anterior structure or a posterior meniscus remnant engaging channel while in another aspect, the anti-migration feature includes a tethering member. Still further, removable radiopaque features are provided to enhance trialing of the implant prior to final implantation within the joint.

The present invention comprises the provision and use of new and improved arthroscopic instrumentation for (i) harvesting a tissue biopsy from a non-critical section of a joint, and (ii) sizing and seating an autologous graft at an implant site.

The present invention provides a method for stabilizing a fractured bone. The method includes positioning an elongate rod in the medullary canal of the fractured bone and forming a passageway through the cortex of the bone. The passageway extends from the exterior surface of the bone to the medullary canal of the bone. The method also includes creating a bonding region on the elongate rod. The bonding region is generally aligned with the passageway of the cortex. Furthermore, the method includes positioning a fastener in the passageway of the cortex and on the bonding region of the elongate rod and thermally bonding the fastener to the bonding region of the elongate rod while the fastener is positioned in the passageway of the cortex.

An implant resection system for preparing an implant site to replace a defect in an articular surface of a first bone includes a first guide configured to be coupled generally to the first bone. The first guide includes a body portion defining a channel configured to receive a pin, wherein the pin is configured to penetrate and form a longitudinally disposed bore within the first bone. The implant resection system further includes a second guide configured to be coupled generally perpendicular to the first bone proximate to the defect by way of the bore. The second guide includes a drill bit configured to form an excision site through a portion of the articular surface in preparation of receipt of an implant.

Disclosed herein are methods, compositions and tools for repairing articular surfaces repair materials and for repairing an articular surface. The articular surface repairs are customizable or highly selectable by patient and geared toward providing optimal fit and function. The surgical tools are designed to be customizable or highly selectable by patient to increase the speed, accuracy and simplicity of performing total or partial arthroplasty.
