Cannula system and method for immobilizing an implanted catheter during catheter anchoring
First Claim
1. A method of implanting a therapy delivery catheter and immobilizing the catheter while the catheter is coupled to an infusion source, the method comprising:
- implanting the catheter such that a distal tip of the catheter is located at a predetermined target site, the catheter at least partially supported by a cinch tube;
applying a clamping member to the catheter at a cinch location associated with the cinch tube, wherein the clamping member is configured to both occlude a lumen defined by the catheter and restrain the catheter relative to the cinch tube at the cinch location;
severing the catheter at a cut location between the cinch location and a proximal end of the catheter;
connecting the catheter to the infusion source; and
removing the clamping member from the catheter.

Abstract
Devices, systems, and methods for immobilizing an implanted catheter tip while the catheter is anchored relative to surrounding tissue. In one embodiment, a cannula system is included that incorporates a cinch tube for guiding the catheter to a target site within a body. The cinch tube may define a cinch window to receive therein a cinch member operable to immobilize and occlude the catheter. The cinch tube may also include an elongate opening proximate the cinch window. The elongate opening allows extraction of a portion of the catheter and subsequent severing of the catheter above the cinch window/occlusion site.
