Reperfusion balloon inflation device
First Claim
1. An ischemic postconditioning system comprising:
- a catheter, the catheter including a plurality of lumens and at least one expandable member;
at least one chamber including a moveable plunger and a return mechanism operatively engaged with the plunger, the moveable plunger dividing the at least one chamber into first and second volumes;
a first pressure source having a first fluid at a first pressure, the first pressure source disposed in fluid communication with the first volume of the chamber;
a second pressure source having a second fluid at a second pressure, the second pressure source and the at least one expandable member disposed in fluid communication with the second volume of the chamber;
wherein the first fluid supplied by the first pressure source displaces the plunger in a first direction delivering at least a portion of the second fluid into the at least one expandable member; and
wherein the return mechanism displaces the plunger in a second direction delivering the second fluid from the second pressure source to the second volume of the chamber.

Abstract
An ischemic postconditioning system and related method comprising a catheter including a plurality of lumens and at least one expandable member with at least one chamber including a moveable plunger and a return mechanism operatively engaged with the plunger. The moveable plunger divides the at least one chamber into first and second volumes. A first pressure source is provided having a first fluid at a first pressure and is disposed in fluid communication with the first volume of the chamber. Further, a second pressure source is provided having a second fluid at a second pressure and is disposed in fluid communication with the second volume of the chamber. Similarly, the at least one expandable member is disposed in fluid communication with the second volume of the chamber. The first fluid supplied by the first pressure source displaces the plunger in a first direction delivering at least a portion of the second fluid into the at least one expandable member. Also, the return mechanism displaces the plunger in a second direction delivering the second fluid from the second pressure source to the second volume of the chamber.

15. An ischemic postconditioning system comprising:
-
a catheter, the catheter including a plurality of lumens and at least one expandable member; a first chamber, the first chamber including a first moveable plunger and a return mechanism operatively engaged with the plunger, the at least one expandable member disposed in fluid communication with the first chamber; a second chamber, the second chamber including a second moveable plunger and return mechanism operatively engaged with the second plunger, the at least one expandable member disposed in fluid communication with the second chamber; at least one pressure source having a fluid disposed therein, the at least one pressure source disposed in fluid communication with the first and second chambers; wherein the fluid supplied by the at least one pressure source to the first chamber displaces the first plunger in a first direction to inflate the at least one expandable member; and wherein the fluid supplied by the at least one pressure source to the second chamber displaces the second plunger in a second direction to deflate the at least one expandable member. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
