摘要： An expandable delivery sheath is provided for intravascular introduction into a patient's vasculature by means of a guiding catheter. An interventional device, such as a stent delivery catheter, is subsequently advanced within the expandable sheath to a point where the stent traverses an arterial lesion. The sheath forms a protective barrier between the lesion and the stent and it delivery catheter, thereby preventing the creation of emboli which might otherwise be produced by abrasion of the stent against the plaque of the arterial lesion. Prior to expansion of the stent, the expandable sheath is retracted from the area of treatment.

摘要： A system used in a blood vessel when an interventional procedure is being performed in a stenosed or occluded region to capture any embolic material which may be created and released into the bloodstream during the procedure. The system includes filtering elements which are capable of occluding a blood vessel distal to an interventional procedure site, while enabling the blood to flow past the occlusion and filtering the blood to capture embolic material which may be released into the blood during a therapeutic interventional procedure. The filtering elements include an expandable member which is capable of being expanded distal to the area of treatment at the interventional procedure site for occluding the blood vessel and for enabling the blood to pass therethrough while preventing emboli from passing therethrough. The system also includes a sheath movable distally and proximally to enable the filtering elements to expand into position distal to the interventional procedure site for capturing embolic material and to collapse the filtering elements to retain the captured embolic material therein.
摘要翻译：当在狭窄或闭塞区域进行介入手术以捕获在手术期间可能产生和释放到血流中的任何栓塞物质时，在血管中使用的系统。该系统包括能够封闭介入手术部位远端的血管的过滤元件，同时使血液能够流过闭塞并过滤血液以捕获在治疗介入手术过程中可释放到血液中的栓塞物质。过滤元件包括可扩张构件，该可膨胀构件能够在介入手术部位处远离扩张区域扩张，用于阻塞血管并使血液能够通过，同时防止栓塞通过。该系统还包括可向远侧和近侧移动的护套，以使得过滤元件能够扩展到介入手术部位的远端位置，用于捕获栓塞材料并使过滤元件折叠以将捕获的栓塞材料保持在其中。

US5908395A Vibrating guidewire 失效

摘要： The invention is directed to a hand held vibration device which imparts reciprocating motion in a guidewire while leaving the guidewire free to rotate about its longitudinal axis, to facilitate advancement of the guidewire through a highly occluded blood vessel. The vibrating device is provided with a lock ring for reversibly preventing guidewire rotation without effecting guidewire reciprocation, and the reciprocation length of the device may be varied. The length the guidewire extends past the distal end of a delivery catheter may be varied from controls on the device which do not require guidewire detachment from the reciprocating mechanism. The device may be used with or without a delivery catheter provided with a curved distal end, the curvature of which can be varied while the catheter is inside the patient.
