摘要： A temporary stent comprises a coil of tubular thermoplastic material and a heating element inside the tubular material, or a film with a metal film resistive heating element coated thereon. A method of temporarily supporting the wall of a vessel comprises the steps of inserting a thermoplastic body having a first outer dimension less than the inside dimension of the vessel into the vessel to the desired support position; heating the thermoplastic above its softening transition temperature and expanding it to a second outer dimension larger than its first outer dimension; cooling the thermoplastic body to below its softening transition temperature while at its second outer dimension; allowing the cooled thermoplastic body to temporarily support the vessel; heating the thermoplastic above its softening transition temperature to soften the thermoplastic; and removing the softened thermoplastic body from the vessel.

摘要： An apparatus for closing and sealing a vascular puncture is connected to an energy supply such that heat is generated in, or thermally conducted to, the tissue, thereby thermally fusing the vascular tissue together. The method for closing and sealing a vascular puncture comprises applying radio frequency or other energy to the tissue, the energy being sufficient to thermally fuse the tissue together, thus sealing the puncture. Embodiments of depth finding and guiding devices, as well as blood vessel occluders, are also disclosed.

摘要： The present invention comprises a method and device for providing an expandable introducer sheath. The method of employing the inventive device comprises inserting an elongate flexible tubular sheath into a vessel (with a proximal end of the sheath extending proximally outward through the skin), to slidably receive intravascular devices. When a larger size introducer sheath is desired, the sheath is manipulated while still in the vessel to expand its inner diameter to a larger size. In one embodiment, the sheath is made of a shape-memory polymer and is manipulated by inserting a heated mandrel (with an outer diameter larger than the inner diameter of the sheath) within the sheath to cause the sheath to expand to an inner diameter at least approximately equal to an outer diameter of the mandrel. The shape-memory polymer material ensures that the sheath will retain its expanded inner diameter. Alternatively, the sheath is formed from a telescoping multi-tubular arrangement of progressively larger tubes. In any case, insertion of the inventive sheath into the skin requires only a single small puncture which is then only expanded as needed while the sheath remains in place.
