Abstract
Abstract A catheter comprising a first elongate flexible member having a cylindrical outer surface and having proximal and distal ends. A metallic band of radio opaque material is disposed on the outer surface of the elongate member in the vicinity of the distal end of the elongate member. A tubular member of a flexible material is carried by the distal end of the elongate member and encapsulates the metallic band to prevent its accidental dislodgment from the tip of the catheter.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
97 words
In a catheter, a first elongate flexible member having a cylindrical outer surface and having proximal and distal ends, a metallic band of radio opaque material disposed on the outer surface of the elongate member in the vicinity of the distal end of the elongate member, a tubular member of a flexible material carried by the distal end of the elongate member and encapsulating the metallic band to prevent its accidental dislodgment from the tip of the catheter the tubular member having formed therein, at the distal end thereof, an annular recess which receives the metallic band.
Claim 2
Dependent Claim
97 words
In a catheter, a first elongate flexible member having a cylindrical outer surface and having proximal and distal ends, a metallic band of radio opaque material disposed on the outer surface of the elongate member in the vicinity of the distal end of the elongate member, a tubular member of a flexible material carried by the distal end of the elongate member and encapsulating the metallic band to prevent its accidental dislodgment from the tip of the catheter the tubular member having formed therein, at the distal end thereof, an annular recess which receives the metallic band.
Claim 3
Dependent Claim
17 words
A catheter as in claim 1 wherein the flexible elongate member is provided with a central lumen.
Claim 4
Dependent Claim
53 words
A catheter as in claim 1 wherein the tubular member extends the length of the catheter, together with a balloon formed on the distal end of the elongate member and providing a chamber and wherein the tubular member in conjunction with the elongate flexible member provides a flow passage extending into the chamber.
Claim 5
Dependent Claim
13 words
A catheter as in claim 1 wherein the catheter is a balloon-type catheter.
Claim 6
Dependent Claim
13 words
A catheter as in claim 1 wherein the catheter is a reperfusion-type catheter.
Claim 7
Dependent Claim
22 words
A catheter as in claim 1 in which the band in a cross section extending axially of the band is generally rectangular.
Claim 8
Dependent Claim
16 words
A catheter as in claim 1 in which the band has a planar outer cylindrical surface.
