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.

(canceled)
A method of retrieving a vascular filter comprising:
- inserting a guidewire having a vascular filter mounted thereon to a treatment site;
- deploying the vascular filter distal to the treatment site;
- disposing an interventional device within a lumen of a tubular body of a retrieval catheter, wherein the retrieval catheter includes a support wire extending proximally from the tubular body;
- disposing a retrieval adapter on the guidewire proximal of the vascular filter such that a proximal end of the retrieval adapter is in engagement with a distal end of the interventional device;
- advancing the retrieval adapter, the interventional device, and the retrieval catheter over the guidewire to the treatment site;
- performing an interventional procedure at the treatment site using the interventional device;
- after completing the interventional procedure, advancing the interventional device distally along the guidewire and capturing the vascular filter with the retrieval adapter;
- after capturing the vascular filter, translating the retrieval catheter relative to the vascular filter and the interventional device such that the vascular filter and the distal end of the interventional device are received within the tubular body;
- withdrawing the vascular filter and the interventional device from the treatment site within the tubular body.
