Abstract
Abstract A catheter insertion tool for the insertion of fragile catheters through a hemostatic valve without damage to the fragile catheter. The catheter insertion tool includes a manipulator body with a "V" slot narrowing to a line of weakness that extends the length of both the manipulator body and attached tubular portion. In the preferred embodiment of the catheter insertion tool the line of weakness is a slit extending through the wall of the catheter extension tool.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
138 words
Apparatus for inserting a catheter into a guide catheter comprising: a. an elongated polyethylene tube having a slit along its length that extends through a wall of the elongated polyethylene tube; b. an enlarged polyethylene tube having a notch for accepting a catheter's distal tip and routing the distal tip through the elongated polyethylene tube into the guide catheter; said notch narrowing to a slit that extends through a wall of said enlarged polyethylene tube along a tapered region at a distal end where the enlarged polyethylene tube narrows to a reduced diameter and is connected to the elongated polyethylene tube; and c. a polyethylene manipulator attached to a proximal end of the enlarged polyethylene tube having a slot extending from its outer circumference to a center region that opens into the notch in the enlarged polyethylene tube.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
22 words
The apparatus of claim 1 wherein the manipulator elongated polyethylene tube and enlarged polyethylene tube are formed form one piece of polyethylene.
Claim 4
Dependent Claim
137 words
Apparatus for inserting a catheter into a guide catheter comprising: a. an elongated polyethylene tube having a line of weakness along its length; b. an enlarged polyethylene tube having a notch at its proximal end that narrows to a line of weakness along its longitudinal axis which extends along a tapered region at its distal end; and c. a polyethylene manipulator, having a slot extending from its outer circumference to a center region, wherein: i. a proximal end of the elongated polyethylene tube is attached to the distal end of the enlarged polyethylene tube; ii. the manipulator is attached to the proximal end of the enlarged polyethylene tube; and iii. the longitudinal line of weakness of the elongated polyethylene tube is aligned with the longitudinal line of weakness in the enlarged tube and with the manipulator slot.
Claim 5
Dependent Claim
