An implant for deployment in select locations or select tissue for regeneration of tissue is disclosed. The implant comprising collagen and or other bio-resorbable materials, where the implant may also be used for therapy delivery. Additionally, the implant may be “matched” to provide the implant with similar physical and / or chemical properties as the host tissue.

Unitary surgical devices (10) are disclosed. One group of the illustrated devices has a pair of biocompatible, bioresorbable anchors (16,18) connected to fixed lengths suture. The anchors (16,18) and fixed length of suture are connected to each other prior to surgery. Another group of unitary surgical devices has a pair of fixating mechanisms (15,17) connected to a base (21) prior to surgery. The second group of illustrated devices generally includes extracellular matrix material either as part of the base (21) or supported on the base (21). The extracellular matrix material serves as tissue regenerating material. In the second group of unitary surgical devices, the fixating mechanisms illustrated generally comprise suture, anchors or pre-formed holes in the base. All of the illustrated unitary surgical devices are useful in repairing a damaged meniscus. The first group of unitary surgical devices can be used to approximate inner surfaces of a tear in the meniscus. The second group of devices can be used either as an insert to be placed between and approximated to the inner surfaces of the tear or as an insert to replace a void in the meniscus left after a meniscectomy.

A cartilage replacement or repair prosthesis comprises a layer of streamlined elastomer elements, preferably in the form of spheres, supported in a matrix material so that the radially opposed surfaces of the spheres are positioned on opposite surfaces of the layer and make contact with the opposed surfaces of the femur and tibia and the forces exerted between these bones extend through the streamlined elements. The matrix material has a substantially lower resistance to deformation than the spheres to control the position of the spheres relative to one another without significantly restraining their load-responsive deformation under forces exerted between the femur and tibia. The layer, with its elastomeric inserts, is sufficiently thin and flexible to allow it to be rolled for arthroscopic insertion into a knee joint.

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.

A multi-barbed apparatus is provided, and methods of use, for penetrating two sides of a wound and holding the edges in apposition. The apparatus may be inserted within a wound or underneath the skin, and mechanically adheres the two sides of the wound together. The apparatus includes a biocompatible substrate carrying a multiplicity of tissue penetrating barbs on a least one side thereof, and may be formed as a rigid or flexible sheet, tube or other shape.

A surgical implant for replacing hyaline cartilage in a knee or other articulating synovial joint has an anchoring side on one side of the implant adapted for fixing the implant to one of the bones in the joint, and a bearing surface on the opposite side of the implant for lubricious rubbing and sliding contact with another bone in the joint. The anchoring side can be configured with an irregular surface for tissue ingrowth. The bearing side can include hydrogel. The implant can be rolled up from an original shape and surgically inserted by arthroscopic means, and opens into its original shape when released inside the joint.

Surgical devices such as implants or suture fastenings are assembled from a plurality of discrete components, one of which components includes a heat bondable plastic material for bonding the components together. At least two components are bonded to each other by the applying heat to the heat bondable plastic material of one component. The heat bondable plastic material is preferably a polymeric or composite material suitable for surgical applications and implantation in humans, and may be a biodegradable material. A laser may be used as the heat source. The present invention is advantageously embodied in heat bonded fastenings for sutures or K-wires, in which a variety of different suture anchors are usable, including expandable distal suture anchors. Other embodiments include a metal bone plate which is held to bone by a metal bone screw and a nut of bondable material bonded to the plate to secure the connection; a piece of bondable material bonded to a metal prosthesis to custom fit the prosthesis; and a surgical implant custom formed by bonding together a plurality of discrete elements one or more of which is bondable.

A patellar 3-D guidance tool includes a template. The template includes at least one contact surface for engaging a surface of the patella. The at least one contact surface substantially conforms with the surface associated with the patellar. At least one guide aperture directs movement of a surgical instrument, wherein the shape and / or position of the guide aperture is based, at least in part, on three or more anatomic reference points associated with the patellar.

Systems and methods treat fractured or diseased bone by deploying more than a single therapeutic tool into the bone. In one arrangement, the systems and methods deploy an expandable body in association with a bone cement nozzle into the bone, such that both occupy the bone interior at the same time. In another arrangement, the systems and methods deploy multiple expandable bodies, which occupy the bone interior volume simultaneously. Expansion of the bodies form cavity or cavities in cancellous bone in the interior bone volume.
