First Claim
Patent Images
1. 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.

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.

8. 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. - View Dependent Claims (9, 10, 11, 12)
