摘要： A stent for placement within a body lumen and comprising a wall structure wherein at least a portion thereof is a hollow wall. The hollow wall has disposed therein a hydrophilic material which can be in the form of a gel, for example, which swells upon introduction of a liquid into the hollow wall to thereby achieve inflation thereof. The hollow wall is fabricated of a semi-permeable membrane whereby fluid from tissues surrounding the stent at the site of placement can pass through the membrane and swell the hydrophilic material to thereby inflate the hollow wall. A drug can be disposed with the hydrophilic material for release through the membrane at the site of stent placement. The entire wall structure of the stent can be a hollow wall, or the wall structure can incorporate both hollow and non-hollow wall portions such as hollow and solid fibers which are braided, woven or wound together.

摘要： A beam adapted for implantation within a bone is able to support bending and torsional loading forces applied thereto. The beam has a stiffness defined by a modulus elasticity, which stiffness varies along the length of the beam to match the corresponding stiffness of the cortical bone adjacent the beam after implantation within the bone. The beam is made from an elongated core formed of continuous filament carbon fibers embedded in a thermoplastic polymer matrix with the carbon filaments extending in a direction substantially parallel to the longitudinal axis of the beam. Encasing the core is a filler molded to the core, which filler is made up of the same thermoplastic polymer as the core but contains no reinforcing carbon fibers. The filler provides the prosthesis with a shape generally conforming to the desired shape of the final prosthetic implant. A sheath formed of carbon reinforced filament fibers embedded in the thermoplastic polymer is wound in spiral formation around the filler and molded thereto. The winding angle and the sheath thickness along the beam may be varied to vary the modulus of elasticity to match that of the cortical bone adjacent thereto.

摘要： A method and apparatus for use in reducing the volatilization of the monomer component of bone cement is used after a prosthesis is implanted and throughout the polymerization of bone cement. The apparatus includes a generally annular inflatable sealing member having a centrally located opening therein for fitting over the exposed end of the prosthesis. The sealing member has an outer diameter covering the exposed surface of the bone cement. The sealing member has a deformable surface disposed in a substantially co-planar relationship with the exposed surface of the bone cement. The sealing member is resiliently expandable by inflation and extends beyond the edges of the bone defining the cavity, to seal the bone cavity upon the deformation of the deformable surface thereon. A pump is provided for inflating the sealing member and causing the deformable surface to apply pressure to the exposed surface of the bone cement. A valving system and a pressure gage are used for controlling the pressure applied to the exposed surface of the bone cement within a range of from 8-14 psi.

摘要： A prosthetic part for use as an orthopedic implant has a base member defining an outer surface for implantation adjacent a prepared bone surface. The outer surface includes a recessed area having a predetermined shape and depth. A first rigid plate having this predetermined shape and having a plurality of elongated slots formed therein is fixedly attached within the recesssed area of the base member. A second rigid plate also having the same predetermined shape as the recess and also having a plurality of elongated slots formed therein is attached to the first rigid plate. The elongated slots of the second plate are angularly offset with respect to the elongated slots in the first plate to produce a controlled porosity. The thicknesses of the first and second plates are predetermined so that the outer surface of the second plate is continuous with the non-recessed outer surface of the base member.

摘要： A prosthetic nucleus for a vertebral disc is made of a hydrogel material. The hydrogel prosthetic nucleus has a shape generally conforming to the natural nucleus pulposus. The hydrogel has a water content of at least 30% and has a compressive strength of 4MNm.sup.-2 or greater. When the hydrogel material is dehydrated, it has a dimension of less than half of that of the hydrated hydrogel nucleus. The prosthetic nucleus may be formed of two or more pieces of hydrogel material which pieces, when combined, have a shape generally conforming to the natural nucleus.
