Abstract
A thin-walled, spiral-cut sleeve is placed on a portion of a ventricular catheter that may be moved into the compression fitting (or similar securing mechanism) of a bolt in a patient. The wall of the sleeve is sufficiently thick so as to prevent the compression fitting from collapsing the drainage lumen of the catheter. A spiral cut in the sleeve allows the sleeve to flex axially, reducing torque forces on the bolt.
Claims17
A catheter system comprising:
- a bolt at least partially disposed within a patient and having a bolt passage therethrough;
- a compression fitting coupled to said bolt and having a fitting passage therethrough and connected to said bolt passage;
- a catheter disposed through said bolt and said compression fitting;
- a catheter exoskeleton having an inner diameter and being disposed along a length of said catheter at a position contactable by said compression fitting;
- said catheter exoskeleton having a plurality of rigid portions spaced apart from each other;
- wherein said compression fitting is compressed against said catheter exoskeleton;
- wherein said catheter exoskeleton maintains said inner diameter;
- and wherein said catheter exoskeleton flexes along a longitudinal axis of said catheter exoskeleton.

A catheter system comprising:
- a bolt member having a proximal end for fixing within a patient and a distal end having a compression fitting;
- a catheter framework disposed through said bolt member and compression fitting, said catheter framework comprising a rigid material and a cut in said rigid material so as to allow a portion of said rigid material to axially flex without being crushed by pressure from said compression fitting;
- a catheter located within said catheter frame work.
A catheter system comprising:
- a bolt at least having a distal end configured for anchoring within a skull of a patient and a bolt passage located through said bolt;
- a compression fitting disposed on a proximal end of said bolt and having a mechanism for compressing against the contents of a fitting passage, said fitting passage in communication with said bolt passage;
- a catheter disposed through said bolt passage and said fitting passage;
- and,
- an exoskeleton comprising a plurality of rigid sections and said exoskeleton being disposed over a length of said catheter contactable by said compression fitting.
