    摘要: A coated medical device (10) including a structure (12) adapted for introduction into a passage or vessel of a patient. The structure is formed of preferably a non-porous base material (14) having a bioactive material layer (18) disposed thereon. The medical device is preferably an implantable stent or balloon (26) of which the bioactive material layer is deposited thereon. The stent can be positioned around the balloon and another layer of the bioactive material posited over the entire structure and extending beyond the ends of the positioned stent. The ends of the balloon extend beyond the ends of the stent and include the bioactive material thereon for delivering the bioactive material to the cells of a vessel wall coming in contact therewith. The balloon further includes a layer of hydrophilic material (58) positioned between the base and bioactive material layers of the balloon.

    摘要: A stent deployment device (110) is provided for deploying a stent in a lumen of a patient. The device can include a catheter (112), a first balloon (122) positioned near a distal end of the catheter and a second balloon (123) adjacent to the first balloon. Alternatively, the second balloon can be positioned over the first balloon. The device also includes an expandable stent (210) positioned over the first balloon and the second balloon. The first balloon comprises a semi-compliant material, a noncompliant material or a compliant material. Similarly, the second balloon comprises a semi-compliant material, a noncompliant material or a compliant material. The first balloon is expandable to a first diameter, while the second balloon can be expandable to a second diameter.

    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.
