    摘要： Thrombectomy catheters are presented that have curved tip portions. A suction lumen extends from at or near the proximal end of the catheter to a suction port at or near the tip portion of the catheter. The curves of the thrombectomy catheter can be selected to place a suction port at or near a vessel wall for the more effective removal of thrombus resulting from directing the suction in the direction of the thrombus. In some embodiments, the tip portion of the catheter can be transitioned from a first configuration for delivery of the catheter into the vessel to a second more curved configuration with a desired design for application of suction. The catheter can be moved in a circumferential and/or lateral direction to cover selected portions of the inner vessel wall. In some embodiments, a partially occlusive structure can be used to reduce and/or redirect flow within the vessel to improve performance of the thrombectomy.

    摘要： Methods and apparatus for making an anastomotic connection between a first conduit and a second conduit. A connector structure having a first end portion and a second end portion is positioned about a balloon catheter, which when pressurized, expands to a significant extent at the distal end thereof. The balloon enlarges the connector structure when positioned at the distal end portion of the balloon to create the anastomosis, and at the same time reduces the axial length of the connector, thereby compressing the first conduit to the second conduit, creating a hemodynamic seal and a firm attachment of the two conduits. After enlargement, the connector structure remains in place and adds structure to the anastomosis. During introduction, the second end portion of the connector is covered by a nosecone assembly to prevent trauma to the second conduit while the apparatus is being introduced. The nosecone assembly has a flexible structure which may change configuration to expose the second set of members after insertion into the second conduit and to allow removal of the nosecone after deployment.

    摘要： In general, aspiration catheters have a suction device, a proximal portion and a shaft with a proximal end and a distal end. Improvements in the aspiration catheter design provide for improved tracking and/or reduced chance of snagging during delivery of the aspiration catheter. In some embodiments, the tip of the shaft has a curve relative to the neutral orientation of the remaining portions of the shaft. In other embodiments, the aspiration catheter further comprises a tracking portion that has a guide lumen. A guide structure can extend through the guide lumen to limit the motion of the tip of the catheter relative to the guide structure during delivery of the aspiration catheter within a patient's vessel. In further embodiments, the aspiration catheter comprises a deflection structure having a tether and a bumper. Improved methods for using the aspiration catheter to recover an embolism protection device are described.

    摘要： Improved embolism protection devices comprises fibers that can have one configuration for delivery of the device and a second configuration in which the device is deployed for filtering of flow within a vessel. In some embodiments, the fibers can be connected to a fiber support, which is connected to an actuating element. The actuating element controls the transition from the delivery configuration to the deployed configuration. The embolism protection device can comprise a guidewire. The fibers can be attached at one end to a fiber support structure and at another end to the guidewire. A hypotube can be attached to the proximal end of the fibers while the guidewire is attached at the distal end of the fibers with the guidewire extending within a central channel of the hypotube. The hypotube can be used to guide the delivery of treatment structures, such as a balloon and/or a stent.

    摘要： A guiding catheter for use in coronary angioplasty and other cardiovascular interventions which incorporates a plurality of segment of selected flexural modulus in the shaft of the device. The segments which have a different flexibility than the sections immediately proximal and distal to them, creating zones in the catheter shaft which are either more or less flexible than other zones of the shaft. The flexibility and length of the shaft in a given zone is then matched to its clinical function and role. A mid-shaft zone is significantly softer than a proximal shaft or distal secondary curve to better traverse the aortic arch shape without storing too much energy. A secondary zone section is designed to have maximum stiffness to provide optimum backup support and stability.
