Abstract: A resorbable, flexible implant in the form of a continuous macro-porous sheet is disclosed. The implant is adapted to protect biological tissue defects, especially bone defects in the mammalian skeletal system, from the interposition of adjacent soft tissues during in vivo repair. The membrane has pores with diameters from 20 microns to 3000 microns. This porosity is such that vasculature and connective tissue cells derived from the adjacent soft tissues including the periosteum can proliferate through the membrane into the bone defect. The thickness of the sheet is such that the sheet has both sufficient flexibility to allow the sheet to be shaped to conform to the configuration of a skeletal region to be repaired, and sufficient tensile strength to allow the sheet to be so shaped without damage to the sheet. The sheet provides enough inherent mechanical strength to withstand pressure from adjacent musculature and does not collapse.

Abstract: A pliable band or hoop that is flexible to normal handling, but cannot stretch circumferentially once it has reached the limits of its circumferential length. The band may have a structural portal to be used for filling, or it may simply be constructed of a fabric-like material that allows a fill tube to perforate its walls to allow for filling. In the latter case, the perforated wall tends to self-seal once the fill tube is withdrawn. The band may be flat or tubular in cross-section. However, unlike a balloon, the band does not require either a bottom or a top, as we found that a top and bottom are unnecessary when using a band or hoop to enclose material injected into a reamed out intervertebral space.

Abstract: The present invention features an acromial-humeral prosthesis for use in performing acromial-humeral arthoplasty. The prosthesis is useful for cases where massive, irreparable tears to the rotator cuff have occurred. The principle function of the prosthesis is to prevent superior migration of the humeral head.
