摘要:
The present invention is directed to distal tip designs for catheter, wherein distal tip material is positioned about an inner shaft. The distal tip material may also be used as a tie layer for thermally bonding two incompatible materials together, such as a waist portion of a balloon to the inner shaft.

Methods and devices incorporating a guidewire entry port subassembly for use in rapid exchange catheters. The use of a subassembly allows for stronger quality control and simpler fabrication of a rapid exchange device. In several embodiments, methods of making a molded guidewire entry port using a mold, often in conjunction with one or more mandrels, are disclosed. Several device embodiments include a separate molded guidewire port as well as molded guidewire ports which are attached, during a molding step, to segments of a catheter.

Medical devices that include micromachined hypotubes or that have themselves been micromachined can provide advantages in flexibility, strength and other desirable properties. Examples of such medical devices may include catheters such as guide catheters and balloon catheters. Such devices may also include dual shaft medical devices in which an outer shaft is reversibly lockable onto an inner shaft.

A catheter system comprises a catheter, an inner shaft, an expandable balloon, and an elongate advancement member. The expandable balloon has an unwrapped state and rewrapped state and the advancement member has a first state and a second state. When the advancement member is in the first state the expandable balloon is in the unwrapped state, and when the advancement member is in the second state the expandable balloon is in the rewrapped state. The unwrapped state has a first length and a first diameter, the rewrapped state has a second length and a second diameter, the second length is equal to or greater than the first length, and the second diameter is less than first diameter. The advancement member in the second state extends through the interior region defined by the expandable balloon.

The compounds of the present invention are represented by the following aryl- and heteroaryl-substituted tetrahydrobenzazepine and dihydrobenzazapine derivatives having formulae I(A-E) and formula (II): where the carbon atom designated * is in the R or S configuration, and the substituents X and R1-R9 are as defined herein.
摘要:
A removable loading tool for use with a catheter assembly wherein the loading tool comprises a body which defines a substantially hollow chamber. The substantially hollow chamber has a first portion and a second portion. The first portion has a first diameter sized to contain at least a portion of the catheter assembly having a stent mounted thereon. The second portion has a second diameter less than that of the first diameter. The body constructed and arranged to protect the at least a portion of the catheter assembly and the stent from undesired contact or damage during loading of a guide wire into the catheter assembly.
