摘要： A medical retrieval basket having superelastic metallic alloy wires attached to the distal end of an inner elongated member tube for percutaneously capturing and removing calculi from a cavity or duct of a patient. The basket comprises kink-resistant superelastic metallic alloy wires such as nitinol which forms a bulbous shape for capturing calculi therein. The ends of the superelastic wires of the basket extend through the passageway of the inner elongated member tube and are attached to the proximal end of the tube. An outer elongated member tube is percutaneously inserted into the biliary or urinary system. The inner member tube is inserted through the outer member tube into a duct, cavity or organ of the patient. The distal ends of both the inner and outer member tubes have a predetermined longitudinal curvature for controlling the positioning of the basket and the tubes within the patient. A sleeve is provided at the proximal end of the inner member tube for limiting the insertion thereof in the outer member tube.

摘要： A stone retrieval basket having superelastic metallic alloy wires attached to the distal end of an inner elongaged member tube for retrieving calculi and crushing them against an outer introducer tube percutaneously inserted into a patient. The basket comprises kink-resistant superelastic metallic alloy wires such as nitinol forming a bulbous shape for capturing calculi therein. The ends of the superelastic wires of the basket are attached to the distal end of a inner elongated member tube with the aid of sleeves crimped thereon, which are soldered or spot welded in recesses about the distal end of the inner tube. The outer tube is percutaneously inserted into the biliary or urinary system in which the basket is then inserted to capture large-sized stones. A peel-away sheath is also included to introduce the basket and inner elongatged member tube into the outer introducer tube. A dilator member, which is extendable through the passageway of the inner tube, removes any residual debris from the tube that may be left during the stone removal procedure.

摘要： A flexible stent having a waveform pattern formed from a sheet of biocompatible material and into a tubular shape for maintaining the patency of a lumen such as in a coronary vessel. The waveform pattern of the stent is formed from a flat sheet of malleable, biocompatible material by, for example, photochemically etching the sheet biocompatible material and leaving a framework or plurality of closed cells. The waveform pattern is formed into a tubular shape around a deflated, delivery catheter balloon with segments of the closed cells being interposed only overlapping a reinforcing member extending longitudinally along the stent. The stent material is treated to reduce the coefficient of friction of the material and to aid in the radial expansion of the stent with the balloon. Radiopaque markers are positioned at the ends of the stent to aid the physician in positioning the stent at an occlusion site.

摘要： In at least one embodiment of the present invention a balloon catheter is provided. The balloon catheter comprises a shaft having a lumen formed therethrough. Connected to the shaft is an inflatable balloon. The inflatable balloon has a balloon wall defining a balloon interior surface and a balloon exterior surface that is opposite the interior surface. In fluid communication with the balloon wall is the lumen for inflating the balloon to define an inflated state and for collapsing the balloon to define a deflated state. The balloon wall is textured in the deflated state such that the balloon interior surface is spatially registered with the balloon exterior surface. The balloon in the inflated state is tensioned to have a surface roughness substantially less than a surface roughness of the balloon in the deflated state.

摘要： An introducer (10) method of percutaneously deploying a self-expanding stent (14) in a body vessel or duct (43). The stent introducer includes an outer elongated member tube (11) having a passage (12) extending longitudinally therein and operable in a first direction (13) for deploying the self-expanding stent in a collapsed condition from the outer member passage. An inner elongated member (15) is positioned in the outer member passage and is operable in a second direction (16) for deploying the stent from the outer member passage. An interconnection mechanism (17) is connected to the outer and inner members for operation thereof, whereby a stent in a collapsed condition is deployed from the outer member passage to an expanded condition. When deployed, the expanded portion of the stent remains fixedly positioned longitudinally in the body vessel or duct as the remaining portion is deployed from the outer member passage. The inner member operates a second operable distance (34) and includes at least one protuberance (19) for pushing the stent out of the outer member passage as the outer member is concomitantly withdrawn a first operable distance (33) from the collapsed, self-expanding stent. The first operable distance is the short length (36) of the stent in an expanded condition, whereas the second operable distance (34) is approximately the distance (37) in the long and short lengths of the stent. The interconnection mechanism of the introducer further includes a transfer assembly (23) coupled to the outer and inner members for controlling the travel distance and direction thereof.

摘要： Balloon catheters, and methods of treatment therewith, are provided including an inflatable first balloon at least partially enclosed by an expandable second balloon that has holes. The annular space between the first balloon and the second balloon is configured to promote delivery of the fluid evenly through holes in the second balloon to avoid problems of underloading and/or overloading. Preferably, the annular space is in communication with the holes, and the annular space is configured to receive and then to release and distribute the fluid via the holes in a substantially uniform manner such that even amounts of fluid are released in the distal and proximal holes. The first balloon may have various configurations including being tapered relative to the second balloon. The second balloon may also be tapered accordingly. The device may also include raised portions disposed in the annular space and configured to define channels having various configurations.

摘要： A medical implant made from multiple layers of non-synthetic, natural tissues is provided. The medical device includes openings that extend radially through the wall of the medical implant. One advantage of the medical implant is that a synthetic support structure is not needed. As a result, problems associated with implanting a foreign material into a body may be avoided.
