Abstract
Abstract A steerable balloon dilatation catheter which is particularly suitable for peripheral arteries having an elongated tubular member with a flexible, inelastic balloon on the distal end. The tubular member has a relatively stiff proximal portion formed of stainless steel and a relatively flexible distal portion formed of a polyester. A fixed guiding member is disposed within the catheter bonded to the proximal portion of the tubular member, to a short relatively rigid cylindrical member bonded to the distal portion of the tubular member and the distal end of the balloon.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
180 words
A dilatation catheter having a fixed guiding member therein for angioplasty procedures, comprising: a) an elongated tubular member having an inner lumen extending therein, a relatively stiff proximal portion and relatively flexible distal portion; b) a short diametrically rigid cylindrical element disposed at least in part within the inner lumen in the distal portion of the tubular member and secured thereto; c) a flexible inelastic inflatable balloon member secured to the distal end of the elongated tubular member; d) a guiding member extending through the interiors of the tubular member and the flexible balloon member and having a portion extending out the distal end of the balloon member, the guiding member being bonded to the proximal portion of the tubular member within the inner lumen extending therein and to the cylindrical element disposed within the distal portion of the tubular member, and the distal end of the balloon being secured about the guiding member; and e) a flexible body disposed about the portion of the guiding member extending out of the distal end of the balloon member and secured thereto.
Claim 2
Dependent Claim
180 words
A dilatation catheter having a fixed guiding member therein for angioplasty procedures, comprising: a) an elongated tubular member having an inner lumen extending therein, a relatively stiff proximal portion and relatively flexible distal portion; b) a short diametrically rigid cylindrical element disposed at least in part within the inner lumen in the distal portion of the tubular member and secured thereto; c) a flexible inelastic inflatable balloon member secured to the distal end of the elongated tubular member; d) a guiding member extending through the interiors of the tubular member and the flexible balloon member and having a portion extending out the distal end of the balloon member, the guiding member being bonded to the proximal portion of the tubular member within the inner lumen extending therein and to the cylindrical element disposed within the distal portion of the tubular member, and the distal end of the balloon being secured about the guiding member; and e) a flexible body disposed about the portion of the guiding member extending out of the distal end of the balloon member and secured thereto.
Claim 3
Dependent Claim
19 words
The dilatation catheter of claim 1 wherein the flexible body disposed about the guiding member is a helical coil.
Claim 4
Dependent Claim
14 words
The dilatation catheter of claim 2 wherein the coil tapers in the distal direction.
Claim 5
Dependent Claim
18 words
The dilatation catheter of claim 1 wherein the proximal portion of the tubular member is formed of hypotubing.
Claim 6
Dependent Claim
20 words
The dilatation catheter of claim 4 wherein the distal portion of the tubular member is formed of high strength plastic.
Claim 7
Dependent Claim
16 words
The dilatation catheter of claim 5 wherein the high strength plastic material is thermoplastic polyester elastomer.
Claim 8
Dependent Claim
18 words
The dilatation catheter of claim 6 wherein the polyester is a copolymer of polybutylene terephthalate and polyether glycol.
Claim 9
Dependent Claim
25 words
The dilatation catheter of claim 1 wherein the distal portion of the balloon has a skirt which is bonded to the guiding member passing therethrough.
Claim 10
Dependent Claim
25 words
The dilatation catheter of claim 1 wherein the balloon is formed of a thermoplastic material selected from the group consisting of polyethylene and polyethylene terephthalate.
Claim 11
Dependent Claim
23 words
The dilatation catheter of claim 1 wherein the guiding member extends to a rounded plug at the distal tip of the flexible member.
Claim 12
Dependent Claim
32 words
The dilatation catheter of claim 1 wherein the length of the distal portion of the tubular member ranges from about 50 to about 85 percent of the length of the tubular member.
Claim 13
Dependent Claim
17 words
The dilatation catheter of claim 1 wherein the short cylindrical element is formed of stainless steel hypotubing.
