摘要： The present invention is a device and a method for boring a perfusion channel into the myocardial tissue of a patient. Structurally, the present invention includes a positioning catheter and a cutting catheter. The positioning catheter is formed with an inflation lumen and a deployment lumen and has an inflatable balloon mounted at its distal end. The cutting catheter has a sharpened distal end and is advanceable through the deployment lumen of the positioning catheter. Advancement of the cutting catheter through the deployment lumen causes the distal end of the cutting catheter to be directed radially outward from the positioning catheter. In use, the positioning catheter is positioned within a target vessel. The inflatable balloon is then expanded to anchor the distal end of the positioning catheter. The cutting catheter is then advanced through the deployment lumen, projecting the distal end of the cutting catheter radially outward from the positioning catheter, boring a perfusion channel in the tissue adjacent to the target vessel.

摘要： An atherectomy system (10) comprises a guide wire (110) which can be inserted into an artery (14) of a patient to a region of occlusion (12), a torque tube (218) having a cutter device (316) affixed to its distal end which is insertable into the artery over the guide wire, and a protective support sheath (418) surrounding the guide wire and the torque tube. Retraction means (410) is provided for controllably retracting the support sheath so as to allow the cutter on the distal end of the torque tube to extend progressively greater distances beyond the distal end of the support sheath. The system also includes means for rotating (22) the torque tube, thereby simultaneously rotating the cutter, and vacuum means (20) connected to the torque tube for extracting dislodged cuttings from the patient's bloodstream. The guide wire is preferably provided with an abutment (116) on its distal end which both mechanically limits the distance the cutter can advance into the patient's body and assists in retrieving the cutter from the patient's body following the atherectomy operation.

摘要： A method of manufacturing polymeric material having enhanced structural integrity includes heating the material to a temperature between the material's glass transition temperature and the material's melt temperature. Once heated, the material is highly overstretched in a first direction and moderately overstretched in a second direction. The material is then held in the overstretched condition while it is allowed to cool to room temperature. Cooling is followed by reheating to a curing temperature. After curing for a predetermined period, the material is again allowed to cool. The completed material has high polymeric orientation in the first direction and moderate polymeric orientation in the second direction. Therefore, the material is characterized by enhanced structural integrity and absence of pinhole defects common to highly oriented polymeric materials.
摘要翻译：制造具有增强的结构完整性的聚合材料的方法包括将材料加热到材料的玻璃化转变温度和材料的熔融温度之间的温度。一旦加热，材料在第一方向上被高度过度拉伸，并在第二方向适度地过度拉伸。然后将材料保持在过度拉伸状态，同时使其冷却至室温。冷却后再加热至固化温度。固化预定时间后，再次使材料冷却。完成的材料在第一方向上具有高聚合物取向，在第二方向上具有适度的聚合物取向。因此，该材料的特征在于增强的结构完整性和高度取向的聚合物材料常见的针孔缺陷。

摘要： An inflatable angioplasty balloon is formed in an unstressed configuration for inflation into an expanded configuration and deflation into a collapsed configuration. The balloon has a body portion (22) and two hollow end portions (24,26), with the end portions being attached to opposite ends of the body portion.
In the balloon's unstressed configuration, the body portion has three flat folding regions (42a,b,c) extending the length of the body portion. Successive folding regions are separated from each other by curved reinforcing regions (44a,b,c). The end portions are configured and oriented to guide the folding regions of the balloon into a pleated, collapsed configuration when the interior of the balloon is evacuated.
