Cannula system and method for immobilizing an implanted catheter during catheter anchoring
First Claim
1. A cannula system for immobilizing a tip of a catheter relative to a target site located within a mammalian skull while the catheter is being secured relative to a burr hole aligned with the target site, the system comprising:
- a guide tube comprising a body fixable relative to a surgical apparatus located outside of the burr hole, and an elongate tubular extension protruding from the body of the guide tube towards the target site;
an elongate cinch tube comprising an inner surface and an outer surface, the inner surface configured to slidably receive the extension therein, wherein a cinch window is formed between the inner and outer surfaces near a distal end of the cinch tube;
a catheter configured for insertion through both the guide tube and the cinch tube; and
a cinch member comprising a first clamp element configured to pass through the cinch window and compress the catheter against the inner surface of the cinch tube.

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.
