Abstract
Abstract A balloon catheter having a flexible tubing containing a plurality of lumens and an inflatable balloon adjacent its distal end is connected to a coaxial unit incorporating a syringe at its proximal end. The syringe applies fluid through at least one of the lumens to inflate the balloon. Other lumens are connected to fluid sources or electrical leads through the coaxial unit for diagnostic or medicinal purposes. Visual means carried by the syringe indicate balloon failure.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
190 words
A balloon catheter assembly comprising a body, a sleeve slidably carried upon the body, an end wall at the distal end of the sleeve, an elongated hollow guide stem carried by the distal end of the body and extending coaxially therefrom and through the said end wall, an elongated flexible tube coaxially coupled at its proximal end to the hollow stem a plurality of lumens in said tube, sealing means carried within the sleeve to form a fluid tight chamber between the end wall and the distal end of the body, a plurality of conduits secured at one end within the body in communication with the lumens, connectors carried upon the free ends of the conduits, a balloon secured to the flexible tube spaced from the distal end thereof, openings in the wall of the said tube and in the said stem in communication with one of the said lumens to provide a continuous fluid path from the sleeve chamber to the interior of the balloon, and openings in the elongated flexible tube at the distal portion thereof in communication with one or more of the lumens in said tube.
Claim 2
Dependent Claim
190 words
A balloon catheter assembly comprising a body, a sleeve slidably carried upon the body, an end wall at the distal end of the sleeve, an elongated hollow guide stem carried by the distal end of the body and extending coaxially therefrom and through the said end wall, an elongated flexible tube coaxially coupled at its proximal end to the hollow stem a plurality of lumens in said tube, sealing means carried within the sleeve to form a fluid tight chamber between the end wall and the distal end of the body, a plurality of conduits secured at one end within the body in communication with the lumens, connectors carried upon the free ends of the conduits, a balloon secured to the flexible tube spaced from the distal end thereof, openings in the wall of the said tube and in the said stem in communication with one of the said lumens to provide a continuous fluid path from the sleeve chamber to the interior of the balloon, and openings in the elongated flexible tube at the distal portion thereof in communication with one or more of the lumens in said tube.
Claim 3
Dependent Claim
18 words
A balloon catheter according to claim 1 in which the sealing means is disposed around the guide stem.
Claim 4
Dependent Claim
31 words
A balloon catheter according to claim 1 in which at least one of the lumens contains an electrical wire and at least one of the connectors is coupled to said wire.
Claim 5
Dependent Claim
100 words
A balloon catheter according to claim 1 in which the sleeve end wall is the form of a centrally bored block having a reduced portion on the distal end thereof, a centrally bored thimble is supported on the sleeve overlying the said end wall to form a chamber around the end of said end wall, said thimble being adapted to receive the guide stem therethrough, a membrane secured between the thimble and the end wall to divide the thimble chamber into two fluid tight compartments and a duct in the end wall connecting the sleeve chamber with the thimber chamber.
Claim 6
Dependent Claim
28 words
A balloon catheter according to claim 4 in which the membrane is formed of a substantially opaque resilient material and the thimble is formed of a translucent material.
Claim 7
Dependent Claim
38 words
A balloon catheter according to claim 5 in which the sleeve sealing means includes an "O" ring disposed around the body, spaced from the distal end thereof and in frictional contact with the inner surface of the sleeve.
Claim 8
Dependent Claim
43 words
A balloon catheter according to Claim 1 in which the end wall and the distal end of the body encloses a fluid tight chamber which is of a volume no greater than the desired volume of fluid to be applied to the balloon.
