A shape-memory device manufactured from shape memory material includes multiple activation temperatures. The multiple activation temperatures arise from either the heat treatment of the device during manufacturing, or by combining different elements with different activation temperatures. To manufacture a shape-memory device with multiple activation temperatures, it is formed into a first shape. A first portion of the shape-memory device is heated to a first temperature, and a second portion of the shape-memory device is heated to a second temperature. The shape-memory device is then worked into a second shape. Accordingly, the first portion has a first transition temperature, and the second portion has a second transition temperature. In use, the shape-memory device is placed into a desired position. Energy is applied such that the first portion, second portion, or both portions are transformed.

An implant including a substantially cohesive aggregate comprising bone-derived particles. Cohesiveness is maintained by a member of mechanical interlocking, engagement of adjacent bone-derived particles with one another through engagement with a binding agent, thermal bonding, chemical bonding, or a matrix material in which the bone-derived particles are retained. The aggregate is shaped as a one-dimensional or two-dimensional body.

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.

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.

Methods of repairing a joint formed by at least two bone sections are provided wherein a biocompatible osteogenic band fabricated from an osteogenic biological material such as bone, tendon, ligament and collagen is affixed to two or more bone sections.
