    摘要： Methods for the conditioning of bioprosthetic material employ bovine pericardial membrane. A laser directed at the fibrous surface of the membrane and moved relative thereto reduces the thickness of the membrane to a specific uniform thickness and smoothes the surface. The wavelength, power and pulse rate of the laser are selected which will smooth the fibrous surface as well as ablate the surface to the appropriate thickness. Alternatively, a dermatome is used to remove a layer of material from the fibrous surface of the membrane. Thinning may also employ compression. Stepwise compression with cross-linking to stabilize the membrane is used to avoid damaging the membrane through inelastic compression. Rather, the membrane is bound in the elastic compressed state through addition cross-linking. The foregoing several thinning techniques may be employed together to achieve strong thin membranes. The finally thinned membrane may then be treated by capping of calcification nucleation sites and borohydride reduction. The leaflets may be formed to have more than one region of uniform thickness, such as a thicker peripheral sewing region.

    摘要： A method and apparatus for making a holographic shadowgram of an object are disclosed. The method and apparatus include a light source for generating and expanding a coherent light beam. The method and apparatus also include a reflector for reflecting the coherent light beam to simultaneously produce a diffuse object beam and a coherent reference beam such that differential vibration between the object and reference beams is substantially eliminated, and for illuminating the object with the object beam and creating an interference pattern between the object and reference beams. The method and apparatus further include a recorder for recording the interference pattern to produce the holographic shadowgram.

    摘要： A treatment for bioprosthetic tissue used in implants or for assembled bioprosthetic heart valves to reduce in vivo calcification. The method includes applying a calcification mitigant such as a capping agent or an antioxidant to the tissue to specifically inhibit oxidation in tissue. Also, the method can be used to inhibit oxidation in dehydrated tissue. The capping agent suppresses the formation of binding sites in the tissue that are exposed or generated by the oxidation and otherwise would, upon implant, attract calcium, phosphate, immunogenic factors, or other precursors to calcification. In one method, tissue leaflets in assembled bioprosthetic heart valves are pretreated with an aldehyde capping agent prior to dehydration and sterilization.

    摘要： Packaging for dry prosthetic tissue heart valves and their delivery systems includes a primary sterile barrier that permits gas sterilization of the tissue implant, and a secondary sterile barrier that also prevents oxidation of the implant during long-term storage. Dry tissue heart valves and their delivery systems are placed within a primary container such as a rigid tray that limits movement of the components therein. The primary container is placed within a secondary container, and the assembly is then sterilized. The outer sterile barrier may include a double seal so that a first gas-permeable seal can be closed for sterilization, after which a second gas-impermeable seal can be closed to seal out any further oxygen contact with the tissue implant. A collapsible delivery handle for a surgical heart valve may be provided which reduces the size of the packaging.
