摘要： A gradually self-expanding stent includes a first plurality of stent cells including a first plurality of circumferentially adjacent structural members in mechanical communication with each other. The stent also includes a second plurality of stent cells including a second plurality of circumferentially adjacent structural members in mechanical communication with each other. The circumferentially adjacent structural members of the first and second plurality of stent cells have a compressed configuration and an expanded configuration. A restraining material is attached to each of the circumferentially adjacent structural members defining each of the second plurality of stent cells such that it substantially covers an entirety of each of the second plurality of stent cells in the compressed configuration. Over time, the restraining material releases the structural members defining each of the second plurality of stent cells, thereby allowing the second plurality of stent cells to assume the expanded configuration.

摘要： A catheter tip assembly (50) is provided with a catheter tip (56) and an inner catheter (54). The catheter tip (56) has a tapered proximal end, an elongate center portion, and a tapered distal end. The inner catheter (54) includes a narrow proximal portion, a narrow elongate center portion (66), and a wide distal end (68). The catheter tip (56) is disposed within the wide distal end (68) of the inner catheter (54). One advantage of the catheter tip assembly is that no proximal-facing edge is formed at the transition between the narrow elongate center portion of the inner catheter and the catheter tip, which may help reduce the risk of the catheter tip snagging on a stent during use.

摘要： A medical device for removing a thrombus includes an outer sheath and an inner catheter. The inner catheter is disposed within the inner lumen of the outer sheath. The device also includes a rollsock which is everted upon itself and connected to the distal ends of the outer sheath and inner catheter. A scraping device is attached to the outer surface of the rollsock, such that when the outer sheath is moved relative to the inner catheter the scraping device is exposed to an inner surface of a body vessel.
