摘要: A “dry” packaging in which a prosthetic heart valve is packaged within a container with hydrogel that can be provided in many forms. Certain embodiments include hydrogel that is preloaded with glycerol or the like. The hydrogel regulates the humidity within the container through a diffusion-driven mechanism if a gradient of humidity between the inside and the outside of the hydrogel exists. Humidity regulation is important to prevent the tissue of the valve structure from drying out. When the partially-hydrated hydrogel is present within container, which is saturated with air of a predefined humidity, the water molecules from the air will be absorbed by the hydrogel if the air humidity is high (i.e. when the thermodynamics favor hydrogel hydration) or vice versa. Various embodiments are configured to also house at least a portion of a delivery device for delivering the prosthetic heart valve.

摘要: Methods and apparatus are disclosed for filling a therapeutic substance or drug within a hollow wire that forms a stent. The stent is placed within a chamber housing a fluid drug formulation. During filling, the chamber is maintained at or near the vapor-liquid equilibrium of the solvent of the fluid drug formulation. To fill the stent, a portion of the stent is placed into contact with the fluid drug formulation until a lumenal space defined by the hollow wire is filled with the fluid drug formulation via capillary action. After filling is complete, the stent is retracted such that the stent is no longer in contact with the fluid drug formulation. The solvent vapor pressure within the chamber is reduced to evaporate a solvent of the fluid drug formulation. A wicking means may control transfer of the fluid drug formulation into the stent.

摘要: A stent includes a bioabsorbable metal, a hydrothermal conversion film covering the bioabsorbable metal, and a coating covering the hydrothermal conversion film. A method for manufacturing a stent includes forming a stent body comprising a bioabsorbable metal, forming a hydrothermal conversion film over surfaces of the stent body, and coating the hydrothermal conversion film with an overcoat.

摘要: A method of preparing dry cross-linked biological tissue. A processing solution is prepared that contains a cross-linking agent and an organic water-soluble liquid. Biological tissue is immersed in the processing solution for an effective period of time to substantially displace water from the biological tissue and substantially cross-link the biological tissue to form dry cross-linked biological tissue.
