Abstract
Abstract A catheter (1) for the repair of an injured blood vessel, characterized by comprising a multiple-lumen type catheter tube having at least two tubular cavities (3a, 3b), at least one dilating member (6) disposed in the distal portion of said catheter tube (4) and adapted to communicate with one of said tubular cavities (3a, 3b), a lateral hole (9) for the injection of a blood coagulation accelerent disposed on said catheter tube (4) at the proximal side than said dilating member (6) side and adapted to communicate with the other tubular cavity, and a hub (14) having a plurality of flow conduit communicating (13a, 13b) severally with said tubualr cavities (3a, 3b) of said catheter tube (4) and adapted to communicate with the proximal portion of said catheter tube (4).

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
111 words
A catheter for the repair of an injured blood vessel, characterized by comprising a multiple-lumen type catheter tube having at least two tubular cavities, at least one dilating member disposed near the extremity of said catheter tube and adapted to communicate with one of said tubular cavities, a lateral hole for the injection of a blood coagulation accelerent disposed on said catheter tube at the proximal side than said dilating member and adapted to communicate with the other tubular cavity, and a hub having a plurality of flow conduits communicating severally with said tubular cavities of said catheter tube and adapted to communicate with the proximal portion of said catheter tube.
Claim 2
Dependent Claim
111 words
A catheter for the repair of an injured blood vessel, characterized by comprising a multiple-lumen type catheter tube having at least two tubular cavities, at least one dilating member disposed near the extremity of said catheter tube and adapted to communicate with one of said tubular cavities, a lateral hole for the injection of a blood coagulation accelerent disposed on said catheter tube at the proximal side than said dilating member and adapted to communicate with the other tubular cavity, and a hub having a plurality of flow conduits communicating severally with said tubular cavities of said catheter tube and adapted to communicate with the proximal portion of said catheter tube.
Claim 3
Dependent Claim
