Abstract
Abstract Proximal manifold and adapter device for use with a catheter having first and second lumens. A manifold having a plurality of arms is provided. One of the arms has a passage therein in communication with the first lumen. Another of the arms is in communication with the second lumen. An interconnector connects said first and second arms for establishing communication between the same. The innerconnector means includes a housing having an inlet port and a valve for establishing communication between the inlet port and the side arms.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
141 words
A proximal manifold and adapter device in combination with a dilatation catheter having a first lumen in fluid communication with a first balloon on the distal portion of the catheter and a second lumen in fluid communication with a second balloon on the distal portion of the catheter, a manifold having a plurality of arms with fluid flow passage therein, one of the arms having a passage therein in communication with the first lumen, another of the arms having a passage therein in communication with the second lumen, and means interconnecting said first and second arms in fluid communication therebetween, said interconnecting means including a housing having an inlet port, discharge ports in fluid communication with said arms, and valve means intermediate said discharge ports for establishing fluid communication between the inlet port and the said arms through the discharge ports.
Claim 2
Dependent Claim
141 words
A proximal manifold and adapter device in combination with a dilatation catheter having a first lumen in fluid communication with a first balloon on the distal portion of the catheter and a second lumen in fluid communication with a second balloon on the distal portion of the catheter, a manifold having a plurality of arms with fluid flow passage therein, one of the arms having a passage therein in communication with the first lumen, another of the arms having a passage therein in communication with the second lumen, and means interconnecting said first and second arms in fluid communication therebetween, said interconnecting means including a housing having an inlet port, discharge ports in fluid communication with said arms, and valve means intermediate said discharge ports for establishing fluid communication between the inlet port and the said arms through the discharge ports.
Claim 3
Dependent Claim
25 words
