    摘要: A guidewire having an intermediate flexibility region to provide trackability and steerability while reducing guide catheter device back out. In one embodiment, the guidewire includes a distal flexibility region, intermediate flexibility region and proximal flexibility region. The intermediate or support flexibility region preferably extends from between about 3 cm to 40 cm proximally of the distal tip. The intermediate region is divided into at least two sections of varying stiffness.

    摘要: A guide wire tip including a core wire having a proximal end and a distal end. The core wire includes a tapered portion proximate the distal end. The tapered portion has a transverse, cross-sectional area which generally decreases distally. The tip is disposed at the distal end of the core wire. The tip has a transverse, cross-sectional area larger than the smallest transverse cross-sectional area of the tapered portion of the core wire. A coil extends over the core wire to the tip. The coil extends over at least a portion of the tapered portion. A radiopaque sheath is disposed proximate the tip and between the core wire and the coil.

    摘要: Methods and devices for retrieving a filter fixed to a guidewire disposed within a blood vessel are disclosed. A catheter for retrieving a filter fixed to a guidewire disposed within a blood vessel in accordance with the present invention includes an elongate shaft and a housing fixed to the elongate shaft proximate a distal end thereof. A tip member is slidingly disposed within a cavity defined by the housing. In a preferred embodiment, the tip member is configured such that the housing is substantially centered about the guidewire. In another preferred embodiment, the tip member is slidingly disposed within the housing, and the tip member may be moved between a first position and a second position.
