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 method of implanting a prosthetic device configured to form at least a portion of a joint is provided. The method includes selecting a first component of the prosthetic device configured to be implanted in a body, determining a placement at which the first component will be fixed relative to a bone of the body, selecting a second component of the prosthetic device configured to be implanted in the body, and determining a placement at which the second component will be fixed relative to the bone. The determination of the placement of the second component is not constrained by a connection to the first component.

A flexible connection unit for use in a spinal fixation device, includes: a longitudinal member having first and second ends; at least one spacer located between the first and second ends, wherein the at least one spacer comprises a first portion made from a first material and a second portion made from a second material; and at least one flexible member located in a longitudinal axial channel of the at least one spacer, wherein the first and second ends substantially limit motion of the at least one spacer in the longitudinal axial direction with respect to the at least one flexible member.
