Abstract

Abstract A steerable dilatation catheter assembly having an adapter with at least one arm (12). A guide wire having proximal and distal ends is provided with the proximal ends (28) extending through the adapter. A flexible tubular member has one end secured to the adapter and extends over the guide wire and has a balloon carried by a distal portion thereof. The distal extremity of the balloon is bonded to the guide wire to form a liquid-tight seal between the guide wire and the balloon. A flexible tip is secured to the guide wire. A rotation limiter (93) secured to the guide wire and carried by the arm for rotating the guide wire through a number of turns less than a predetermined number of turns.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 57 words
A rotation limiting device comprising a rotatable member, means adapted to secure the guide wire to the rotatable member, and means including a plurality of superposed discs engaging the rotatable member for prevention of rotation of the rotatable member for more than a predetermined number of times, each of said discs including cooperative protrusion and recess means.
Claim 2
Dependent Claim 57 words
A rotation limiting device comprising a rotatable member, means adapted to secure the guide wire to the rotatable member, and means including a plurality of superposed discs engaging the rotatable member for prevention of rotation of the rotatable member for more than a predetermined number of times, each of said discs including cooperative protrusion and recess means.
Claim 3
Dependent Claim 148 words
A rotation limiting device for use with a steerable dilatation catheter comprising an adapter with at least one arm, a guide wire having proximal and distal ends with the proximal end extending through the adapter and extending over the guide wire and having a balloon carried by the distal portion thereof, the balloon having a distal extremity which is bonded to the guide wire to form a liquid-tight seal between the guide wire and the balloon and a flexible tip secured to the guide wire, wherein the rotation limiting device comprises a rotatable member, means adapted to secure the guide wire to the rotatable member, and means including a plurality of superposed discs engaging the rotatable member for prevention of rotation of the rotatable member for more than a predetermined number of times, each of said discs including cooperative protrusion and recess means as claimed in claim 1.
Claim 4
Dependent Claim 37 words
A device as claimed in claim 1 or claim 2 wherein said rotatable member is in the form of a housing having a cylindrical recess therein and wherein said discs may be disposed in said cylindrical recess.
Claim 5
Dependent Claim 29 words
A device as claimed in claim 3 further comprising an adapter wherein the housing and the adapter each are provided with a cooperative means to cooperate with the discs.
Claim 6
Dependent Claim 33 words
A device as claimed in claim 4 wherein each disc is provided with a recess extending through substantially 360° and a protrusion which is adapted to seat in the recess of another disc.
