Abstract
A pre-assembled kit for administering ischemic postconditioning comprising a catheter and a handle having a fluid circuit to control and modulate flow of inflation fluid to and from a balloon wherein the catheter is free from additional assembly and preparation procedures such that it is ready-to-use within a variety of vessel sizes.
Claims25
A method of administering ischemic postconditioning comprising:
- providing a catheter, the catheter including at least one expandable member, the catheter configured for use in a variety of vessel sizes, the catheter configured to receive a guidewire of predetermined size;
- providing a handle having a pressure source positioned entirely within the handle;
- coupling the pressure source with the catheter, the at least one expandable member disposed in fluid communication with the pressure source, wherein the catheter and handle are free from any required additional assembly and preparation procedures;
- positioning the at least one expandable member at a predetermined location within a vessel;
- inflating the at least one expandable member with an inflation fluid via an inflation lumen for a period of time;
- and
- deflating the at least one expandable member via an independent deflation lumen.
