摘要： A reinforced catheter or sheath includes an inner tube manufactured via an extrusion process from a mixture of thermoplastic and hollow glass beads. The resultant tube exhibits an inner goose bump surface that defines a central lumen. A reinforcement, such as a braid and/or coil is attached to at least a segment of the outer surface of the inner tube. A second tube of thermoplastic is extruded over at least a portion of the reinforcement. The inner goose bump surface exhibits a net low coefficient of friction comparable to that of polytetrafluoroethylene (PTFE).

摘要： A medical balloon catheter including a shaft comprised of a cross-wound coil tube and a sleeve surrounding the cross-wound coil tube. The cross-wound coil tube includes a monofilament inner coil disposed within a monofilament outer coil. The inner and outer coils are wound in opposite pitch directions. In at least one embodiment, at least one of the inner and outer coils includes a tapered distal section having a tapered diameter. In at least another embodiment, the inner coil extends distally beyond the distal end of the outer coil, providing increased flexibility in a distal portion of the shaft. An inflation balloon is attached to the distal end of the shaft. The shaft includes an inflation lumen formed through the inner coil and a wire guide lumen formed through the distal portion of the shaft and extending through the chamber of the balloon.

摘要： Catheter balloon assemblies (10) for delivering a therapeutic agent to a body vessel are provided, as well as related methods of manufacturing and methods of treatment. The catheter balloon assemblies may include a concentrically disposed dual balloon assembly at the distal portion of the catheter having an inner balloon (44), a porous outer balloon (42) concentrically arrayed around the inner balloon and a catheter shaft (30) adapted to deliver a therapeutic agent to the body vessel through the apertures in the outer balloon. Radial outward expansion of the inner balloon may urge the outer balloon into contact with the wall of a body vessel, where the therapeutic agent may be delivered from the catheter shaft through apertures in the outer balloon directly to the wall of the body vessel. Preferably, the catheter balloon assemblies include a stiffening' member (210) within the proximal portion and/or a plurality of lumens lined with a fluorinated hydrocarbon to independently inflate the inner balloon, deliver the therapeutic agent through the outer balloon and house a wire guide (50). The catheter balloon assemblies may provide improved tractability and/or pushability characteristics.

摘要： A catheter for delivering an interventional device to a target site within the body of a patient. The catheter comprises an elongated shaft having a plurality of lumens extending longitudinally therein. The shaft has a proximal portion defining at least two lumens, an intermediate portion having fewer lumens than the proximal portion, and a distal portion configured for carrying the interventional device. The proximal and distal portions each have a greater stiffness than the stiffness of the intermediate portion. A stiffening member is incorporated into the intermediate portion of the shaft. The stiffening member is sized and positioned along the shaft in a manner such that the stiffness of the intermediate portion is increased relative to the stiffness of the proximal portion and the distal portion.

摘要： A method of treating lower leg ischemia includes advancing a wire guide upstream through a vascular access sheath extending into an artery, and increasing a downstream flow of blood at least in part by dilating a constriction in the artery with a treatment mechanism guided into the constriction via the wire guide. The method further includes withdrawing a catheter which is coupled with the treatment mechanism from the patient at the percutaneous entry point via sliding the catheter downstream through the vascular access sheath. A low profile balloon may be used as the treatment mechanism, and is advanced through the artery while the vascular access sheath protects the artery from irritation such that spasm of the artery is less likely to occur. Reduced risk of spasm advantageously enables retrograde access to chronic total occlusions such that multiple entry points into a patient's body are not necessary.
摘要翻译：一种治疗小腿缺血的方法包括将导丝器向上游延伸穿过延伸到动脉中的血管通路护套，以及至少部分地通过用引导到狭窄部中的治疗机构扩张动脉中的狭窄来增加血液的下游流动导线。该方法还包括通过将下游的导管滑动通过血管通路鞘来抽出与经皮入口点处的患者与治疗机构联接的导管。可以使用低调气囊作为治疗机构，并且通过动脉前进，同时血管通路护套保护动脉免受刺激，使得动脉痉挛不太可能发生。降低痉挛的风险有利地使逆行进入慢性全部闭塞，使得不需要进入患者身体的多个入口点。

摘要： A method for embolic protection during treatment of a stenotic lesion in a body vessel is provided. The method comprises disposing an embolic protection device in an undeployed state in the body vessel. The device comprises a basket with a set of struts extending from a distal end to a proximal end of the basket, the struts being arranged to define an opening at the distal end, the basket having an expanded state and a collapsed state. A core wire with a distal end and a proximal end is able to reciprocate through the opening at the distal end of the basket. A filter bag is attached only at the distal end of the core wire, the filter bag being located distally to the distal end of the basket when in the collapsed state. The method further comprises moving the core wire relative to the basket to expand the basket and the filter bag in a deployed state downstream from the stenotic lesion to capture emboli during treatment of the stenotic lesion.
