    摘要： The present invention comprises a catheter method of manufacture. The method includes the provision of a subassembly of a lubricious liner and reinforcement. Over the subassembly, a shaft tube, transition tube, and soft tip tube are placed in an abutting relationship to each other, forming an assembly. A first tube of heat shrink is advanced over the assembly, heat is applied to fuse the assembly, and the first heat shrink is removed. Subsequently, the soft tip of the catheter is shaped using a second tube of heat shrink, which is placed over the distal end of the assembly. Heat is applied to the second heat shrink to cause the tip material to flow and to draw the tip material over the distal end of the lubricious liner. The second heat shrink is removed, completing the catheter manufacture.

    摘要： A catheter adapted for placement within a living anatomy, such as the human coronary arterial system, comprises a proximal portion, a first arcuate portion, a second arcuate portion, and a distal tip. The catheter is shaped so that with the distal tip engaged in the coronary ostium, the ellipsoidal shaped second arcuate portion is in contact with the contralateral wall of the aorta, the catheter thus resisting forces tending to displace the distal tip from the ostium.

    摘要： Assemblies and methods provide for implantation of multiple medical leads to a defined space within the body, such as the epidural space, through a single entry. A catheter having multiple lumens or alternatively a single oblong lumen may be used. A distal end of the catheter enters the defined space through the single entry such that the distal ends of the multiple lumens or the oblong lumen are present in the defined space. Medical leads are introduced through the multiple lumens or the oblong lumen into the defined space. In some cases, the distal end of the catheter may be deflectable to direct the medical leads within the defined space. In other cases, sheaths may be present within each lumen of the catheter where the sheaths may be extended into the defined space and deflect to direct the medical leads that are being passed through a lumen of the sheaths.

    摘要： The device utilizes a reversibly expandable body partially covered by a blood impermeable sleeve. The device has a low profile collapsed state for delivery and a expanded state for deployment. The impermeable sleeve extends from a proximal portion to a distal portion of the expandable body and generally follows the contour of the expandable body. When deployed, the device is configured in the expanded state and has a generally hourglass, or dumbbell shape. In the expanded state, portions of the sleeve adjacent to the proximal and distal portions are placed in apposition to a vessel wall and blood is free to flow through the expandable body via inlets and outlets provided in the proximal and distal portions. As a result, an isolated treatment space is created that surrounds the device between the vessel wall and the blood impermeable sleeve adjacent to the neck portion of the expandable body.

    摘要： The invention includes an exchange system, a guidewire anchoring means and a method of use for catheters exchangeable over a guidewire (55). The guidewire anchoring means restricts movement between the guidewire (55) and the anchoring means. The anchoring means comprises a shaft (35) with a longitudinal lumen (80) therethrough, the lumen (80) being in fluid communication with a balloon (25 or 30) disposed on the distal end of the shaft (35). A tubular split housing (5 or 10) surrounds the distal end of the shaft (35) and adheres to the balloon (25 or 30), the balloon (25 or 30) being sized to expand to a larger size than the inside diameter of the split housing (5 or 10). The inside diameter of the split housing (5 or 10) is sized to slidably receive a catheter, while the outside diameter of the split housing (5 or 10) is sized to slidably fit within a guide catheter (50 ).
