Abstract

Abstract Abstract of the Disclosure A combination guiding catheter assembly and a dilating catheter assembly. The guiding catheter assembly includes a first flexible tubular member formed of a meterial which has a low coefficient of friction and a second flexible tubular member encasing said first tubular member so that the first tubular member fits tightly in the second tubular member. The combined first and second tubular members have proximal and distal ends with a fitting mounted on the proximal end. The dilating catheter assembly includes a flexible tubular member. The tubular member of the dilating catheter assembly having proximal and distal ends and an inflatable annular portion formed integral with the tubular member of the dilating catheter assembly near the distal end thereof. A fitting is mounted on the proximal end of the tubular member of the dilating catheter assembly. The dilating catheter assembly is disposed within the guiding catheter assembly. An inflator is provided for inflating and deflating the inflatable annular portion.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 174 words
In a guiding catheter assembly, a first flexible tubular member formed of a material which has a low coefficient of friction and having a guid-ing passageway extending therethrough, a second flexible tubular member encas-ing said first tubular member so that the first tubular member fits tightly in said second tubular member, and so that the second tubular member is coextensive in length with the first tubular member, said second tubular member being formed of a plastic material which is flexible but which has a greater rigidity than said first tubular member so as to provide a catheter assembly with the desired rigidity to permit manoeuvering of the same, the first and second tubular mem-bers having proximal and distal ends, the distal ends each having a bend therein, a fitting mounted on the proximal ends to permit access to the passage in the first tubular member and an additional tubular member engaging the fitting and the proximal ends with a shrink fit to form an adhesive-free liquid-tight con-nection between the fitting and the proximal ends.
Claim 2
Dependent Claim 174 words
In a guiding catheter assembly, a first flexible tubular member formed of a material which has a low coefficient of friction and having a guid-ing passageway extending therethrough, a second flexible tubular member encas-ing said first tubular member so that the first tubular member fits tightly in said second tubular member, and so that the second tubular member is coextensive in length with the first tubular member, said second tubular member being formed of a plastic material which is flexible but which has a greater rigidity than said first tubular member so as to provide a catheter assembly with the desired rigidity to permit manoeuvering of the same, the first and second tubular mem-bers having proximal and distal ends, the distal ends each having a bend therein, a fitting mounted on the proximal ends to permit access to the passage in the first tubular member and an additional tubular member engaging the fitting and the proximal ends with a shrink fit to form an adhesive-free liquid-tight con-nection between the fitting and the proximal ends.
Claim 3
Dependent Claim 20 words
A guiding catheter assembly as in claim 1 wherein said first flexible tubular member is formed of a tetrafluoroethylene polymer.
Claim 4
Dependent Claim 17 words
A guiding catheter assembly as in claim 2 wherein said distal ends have a permanent bend therein.
Claim 5
Dependent Claim 23 words
A guiding catheter assembly as in claim 3 wherein the distal end of the second tubular member is provided with an annular recess.
