A method of manufacturing a covered stent is disclosed. The method includes winding a first PTFE tape around a cylinder body of a jig, winding a second PTFE tape around a stent including the jig fitted therein, heating the stent in an oven, fitting the stent into upper and lower elastic members, fitting the elastic members into a mold, pressing the upper elastic member to bond the PTFE tapes to each other and to thus form a first film at a cylindrical body of the stent, taking the elastic members out of the mold, taking the stent out of the elastic members, removing the jig from the stent, forming a silicone coating layer at an expansion portion of the stent, and sewing the spaces in the expansion portion, the second PTFE tape, and the silicone coating layer to form a second film at the expansion portion.

The invention is an improved biocompatible surface for a variety of medical purposes. The biocompatible surface employs a unique tight microstructure that demonstrates enhanced cellular response in the body, particularly when placed in contact with blood. As a blood contact surface, the present invention can be beneficially employed in a wide variety of implantable devices and in many other devices and equipment that come in contact with blood.

Stents generally can include a tubular structure having circumferentially positioned undulating wires that extend over a majority of a length of the stent such that the undulations oscillate circumferentially to define a circumference of the stent. The undulations can wrap over and under adjacent undulations to form an interwoven structure. Additionally, or alternatively, adjacent wires can be joined. Wires forming the stent can be cut from elastic tubing such that each wire has a three-dimensional shape.

Anchors and anchoring methods suitable for use with implantable assemblies that include an implantable device, including but not limited to implantable sensing devices and implantable wireless sensing devices adapted to monitor physiological parameters within living bodies. Such an implantable device has a housing containing a transducer, electrical circuitry, and an antenna. The transducer is located at a first end of the housing opposite a second end of the housing. At least the transducer is located within a housing portion of the housing in which the antenna is not located. The implantable assembly further includes an anchor is adapted for securing the implantable device within a living body.

The present disclosure relates to several embodiments of a stent. For example, the present disclosure describes a stent comprising a material selected from a biocompatible material, a bioabsorbable material, and combinations thereof; and particles selected from biocompatible amorphous particles, bioabsorbable amorphous particles, and combinations thereof.

The stent may also include a coating of a material selected from a biocompatible material, a bioabsorbable material, and combinations thereof; nanocapsules and a therapeutic agent encapsulated in the nanocapsules.

The stent disclosed herein enables the walls of an airway or blood vessel to be supported, while there is controlled delivery of the therapeutic agent to said airway or blood vessel to prevent, cure, alleviate or repair symptoms of disease.

A device includes a balloon and an interface. The balloon has an outer surface and a central lumen aligned on a longitudinal axis. The balloon is configured to receive a compressible fluid. The interface is coupled to the outer surface and has an external surface configured to bond with a tissue.

An expandable tube for deployment within a blood vessel is disclosed. In one arrangement, the tube comprises an elongate frame that is reversibly switchable from a radially expanded and longitudinally contracted state to a radially contracted and longitudinally expanded state. The frame comprises a plurality of longitudinally deformable elements for providing longitudinal expansion and contraction of the frame and a plurality of circumferentially deformable elements for providing radial expansion and contraction of the frame. The longitudinally deformable elements can be expanded or contracted longitudinally substantially without any change in the shape of the circumferentially deformable elements. The plurality of circumferentially deformable elements comprises a plurality of sets of circumferentially deformable elements. Each set of circumferentially deformable elements forms a closed ring around an axis of elongation of the frame. Each closed ring consisting exclusively of the circumferentially deformable elements. At least two of the closed rings occupy overlapping ranges of longitudinal positions when the frame is in the radially expanded and longitudinally contracted state and occupy non-overlapping ranges of longitudinal positions when the frame is in the radially contracted and longitudinally expanded state.
