Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
60 words
A vascular catheter for angioplasty procedures having an elongated catheter body with an inflatable balloon on the distal extremity thereof characterized by a tubular member having a longitudinally flexible tubular substructure with a resin-impregnated first fibrous layer extending from the proximal to the distal end thereof which is formed from at least one continuous strand wrapped around the tubular substructure.
Claim 2
Dependent Claim
60 words
A vascular catheter for angioplasty procedures having an elongated catheter body with an inflatable balloon on the distal extremity thereof characterized by a tubular member having a longitudinally flexible tubular substructure with a resin-impregnated first fibrous layer extending from the proximal to the distal end thereof which is formed from at least one continuous strand wrapped around the tubular substructure.
Claim 3
Dependent Claim
36 words
The catheter of claim 1 wherein the tubular member is an outer member of the catheter body which has an inflatable balloon secured by the proximal end thereof to the distal end of the tubular member.
Claim 4
Dependent Claim
32 words
The catheter of claim 2 wherein the distal end of the balloon is secured to a guiding element which extends through the interior of the balloon and out the distal end thereof.
Claim 5
Dependent Claim
36 words
The catheter of claim 1 wherein the tubular member is an inner member of the catheter body and has the inflatable balloon secured by the distal end thereof to the distal end of the tubular member.
Claim 6
Dependent Claim
61 words
The catheter of any one of the preceding claims wherein the tubular member has a second resin-impregnated fibrous layer which extends over the first fibrous layer from the proximal end of the tubular member to a location proximal to the distal end of the tubular member and which is formed from at least one continuous strand wrapped over the first layer.
Claim 7
Dependent Claim
27 words
The catheter of any one of the preceding claims wherein the strand is made from a material selected from the group consisting of aramid, nylon and polyester.
Claim 8
Dependent Claim
29 words
The catheter of any one of the preceding claims wherein the wraps of the continuous strand about the tubular substructure are disposed immediately adjacent to preceding and following wraps.
Claim 9
Dependent Claim
39 words
The catheter of any one of the preceding claims wherein the continuous strand is wrapped about the distal portion of the tubular substructure at an angle with respect to the longitudinal axis thereof between about 60° and about 85°.
Claim 10
Dependent Claim
35 words
The catheter of claim 8 wherein the continuous strand is wrapped about the proximal portion of the tubular substructure at an angle with respect to the longitudinal axis thereof between about 30° and about 60°.
Claim 11
Dependent Claim
43 words
The catheter of any one of the preceding claims wherein the continuous strand is wrapped about the proximal portion of the tubular substructure with the wraps longitudinally spaced from each other a distance of about 2-6 times the width of the wrapped strand.
Claim 12
Dependent Claim
18 words
The vascular catheter of any one of the preceding claims wherein the impregnated resin is an epoxy resin.
Claim 13
Dependent Claim
53 words
The vascular catheter of any one of the preceding claims wherein the continuous strand is wrapped about the distal portion of the tubular substructure at an angle with respect to the longitudinal axis thereof between about 30° to about 45° greater than the strand wraps on the proximal portion of the tubular member.
