Abstract
Abstract A clamp for connecting and securing a catheter in position within a tubular structure has a positioning ring and support member to align and slidingly affix the clamp along the catheter and includes a split toothed plastic clamping ring which may be expanded by the application of forceps to enclose the catheter and a section of the tubular structure into which the catheter is inserted and, when released, forms a toothed occlusal seal, enclosing with mild pressure the tubular structure between the clamp and the catheter. The clamp is designed to permit the insertion and securing of a catheter into an opening cut along the length of the tubular structure, by providing a passage or gap for the passage of the distal portion of the tubular structure.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
173 words
An apparatus for clamping a catheter insertably within a continuous structure comprising: a. Guide means, slidably enclosing said catheter, adapted for motion along a length of said catheter adjacent to tip thereof; b. Beam support means extending outwardly from guide means in a direction towards said tip; c. A split ring clamp means affixed at an end of said beam support means opposite said guide means comprising a first semi-cylindrical resilient clamping member extending from a point adjacent said support beam, encompassing a semi-circumferential section of said catheter; d. A second, semi-cylindrical resilient clamping member extending from a point upon said support beam and opposing engagement to said first member encompassing a second semi-circumference of said catheter; e. Means for deflecting said first and said second member from a position contactingly encompassing said catheter to a position apart from said catheter; and f. Means upon the interface of said first and said second members for establishing a sealing relationship between said members, said catheter, and an interposed tubular structure circumferentially surrounding said catheter;
Claim 2

Means upon the interface of said first and said second members for establishing a sealing relationship between said members, said catheter, and an interposed tubular structure circumferentially surrounding said catheter;
Claim 3
Dependent Claim
33 words
The apparatus as described in claim 1 above wherein said sealing means further comprises a periodically ridged toothed structure extending inwardly from an inner surface of said first member and said second member.
