Systems and methods for vascular filter retrieval

Abstract

Apparatus and methods for retrieving a vascular filter from a vessel are provided wherein a retrieval adapter is delivered to a treatment site concurrently along with an interventional device to reduce the number of steps required to remove the vascular filter. The retrieval adapter also reduces the possibility of entangling the vascular filter with a stent disposed within the vessel during removal of the vascular filter. A separate retrieval catheter is also described for use in conjunction with the retrieval adapter.

1 . Apparatus for use in conjunction with an interventional device in retrieving a vascular filter disposed on a guidewire from a vessel, the apparatus comprising: a retrieval adapter having a proximal end, a distal end and a lumen, the retrieval adapter configured to be disposed on a distal region of the guidewire so that the proximal end engages a distal end of the interventional device, the retrieval adapter configured to receive at least a portion of the vascular filter within the lumen during retrieval of the vascular filter from the vessel.
