Abstract

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.

Claims
