摘要: Devices for palliating gastrointestinal strictures using rapid exchange type enteral stent placement catheters. The catheter may include an inner member and an outer member, with the two members being slidable with respect to one another. In various device embodiments, a ramp for directing a guidewire out from within the catheter is provided using portions of the outer member or a shaped mandrel. The inner member may take a number of forms, including a tubular distal portion, a skived or integrally attached elongate midsection, and a proximal portion. A mandrel can be used in a portion proximal of the guidewire ramp, with the mandrel taking one of several disclosed forms.

摘要: This invention provides smooth delivery and accurate positioning of prostheses in the body. In embodiments, systems are provided that include elongate members extending generally along the axis of a supporting catheter to a free ends. The elongate members extend through openings in the prosthesis to maintain the position of the prosthesis on the catheter. The prosthesis can be released from the catheter by relative axial motion of the catheter and the elongate members such that the free ends are removed from the openings in the prosthesis. In embodiments, the elongate members hold the distal end of a self-expanding stent at a desired axial location and in radial compaction as a restraining sheath is withdrawn. The friction between the sheath and stent puts the stent under tension, which reduces the radial force on the sheath wall, allowing smoother retraction. Proximal portions of the stent radially expand and axially shorten. The distal end, however, is maintained at the desired axial location and released from the catheter to contact the body lumen wall without substantial axial shortening.
摘要翻译: 本发明提供了假体在体内的平稳输送和精确定位。 在实施例中,提供了包括通常沿着支撑导管的轴线延伸到自由端的细长构件的系统。 细长构件延伸穿过假体中的开口,以维持假体在导管上的位置。 假体可以通过导管和细长构件的相对轴向运动从导管释放,使得自由端从假体中的开口移除。 在实施例中,细长构件将自膨胀支架的远端保持在期望的轴向位置处,并且随着约束护套被拉出而将其径向压紧。 护套和支架之间的摩擦力使支架处于张力状态,从而降低了护套壁上的径向力,从而实现了更平滑的收缩。 支架的近端部分径向扩张并轴向缩短。 然而,远端保持在期望的轴向位置并且从导管释放以接触体腔壁而没有显着的轴向缩短。

摘要: A sleeve for attaching a medical balloon to a catheter utilizing a balloon (8). The sleeve comprises a plurality of co-extruded and coextensive layers of different polymeric materials (20A, 20B) at least one of which is a base structural layer (20B) and the other of which (20A) is formed of polyethylene and copolymers thereof or of Selar. The base structural layer is thicker than the other layer. The diameter of the catheter at the joint (10, 11) is substantially the same as the tube.

摘要: A prosthesis delivery system having a balloon catheter with an inflatable balloon on its exterior. The balloon is inflatable by injection of fluid through a lumen in the catheter and the balloon is initially partially constrained against inflation by a constraint. A tubular prosthesis is disposed on the catheter over at least a portion of the balloon and a portion of the constraint. The tubular prosthesis has a contracted condition and an expanded condition. The tubular prosthesis is initially disposed on the catheter in the contracted condition. Further, a balloon catheter includes a constraint so that the balloon may be sequentially inflated for dilatation purposes such as in a valvuloplasty operation.
