Claims10
A method for retrieving a venous filter disposed on a catheter body, comprising:
- a. threading an introducer sheath over the proximal end of the catheter body.
- b. inserting a first end of the introducer sheath into a patient access site and into the patient's vasculature;
- c. threading a retrieval sheath over the proximal end of the catheter body;
- d. advancing the retrieval sheath into the patient's vasculature through the introducer sheath and toward a distal end of the catheter body proximate the venous filter;
- e. enveloping the venous filter into a distal end of the retrieval sheath thereby capturing the venous filter within the retrieval sheath;
- and
- f. concurrently withdrawing the retrieval sheath, the venous filter and the catheter body from the patient.
