Balloon catheter
First Claim
1. A catheter comprising:
- a catheter body having an exterior surface, a proximal end, a distal end, and a first lumen extending through at least a portion of the catheter body;
an inflatable member mounted to the exterior surface of the catheter body adjacent the distal end, fluidly connected to said first lumen, and adapted for inflation between an expanded state and a retracted state, the inflatable member having a proximal end, a distal end, and an interior surface; and
a solid sleeve provided on the exterior surface of the catheter body intermediate the proximal and distal ends of the inflatable member, said sleeve having at least one fluid aperture formed therein to fluidly connect the interior of the inflatable member with the first lumen and adapted to prevent inadvertent adhesion of the interior surface of the inflatable member to the exterior surface of the catheter body.

Abstract
An improved balloon catheter has a catheter body with an expandable member, such as a balloon, mounted to the exterior surface thereof. Preferably, means for preventing sticking of the expandable balloon to the exterior surface of the catheter body are provided. In one aspect, the catheter has an expandable member, preferably a balloon, positioned substantially equidistant from the proximal and distal ends of the catheter body. The retention catheter is positioned externally of the heart and partially surrounds the heart so that the balloon is positioned immediately adjacent the coronary sinus and when inflated, the balloon bears against the coronary sinus and at least one of the inferior vena cava and diaphragm thereby preventing inadvertent movement or removal of the RCSP catheter from the coronary sinus.

6. A catheter for use in the retrograde administration of cardioplegia solution, the catheter comprising:
-
a catheter body having an exterior surface, a proximal end, a distal end, and a lumen extending through at least a portion of the catheter body; an inflatable member, having an interior surface, the inflatable member being mounted on the exterior surface of the catheter body substantially equally spaced from the proximal and distal ends and fluidly connected to the lumen, the inflatable member being adapted to be selectively inflated between a retracted state and an expanded state in response to the introduction of pressurized fluid into the lumen of the catheter body, the catheter being adapted to be positioned externally of the heart, immediately adjacent to and intermediate the inferior vena cava and coronary sinus ostia during the retrograde administration of cardioplegia solution; and a fluid permeable sleeve for preventing inadvertent adhesion of the interior surface of the inflatable member to the exterior surface of the catheter body, the sleeve being provided on one of the catheter body and inflatable member intermediate the interior surface of the inflatable member and the exterior surface of the catheter body, wherein the fluid permeable sleeve comprises a solid sleeve having at least one fluid aperture formed therein, the fluid aperture adapted to fluidly connect the first lumen to the inflatable member. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 18, 19)

14. A catheter for use in the retrograde administration of cardioplegia solution, the catheter comprising:
-
a catheter body having an exterior surface, a proximal end, a distal end, and a lumen extending through at least a portion of the catheter body; an inflatable member, having an interior surface, the inflatable member being mounted on the exterior surface of the catheter body substantially equally spaced from the proximal and distal ends and fluidly connected to the lumen, the inflatable member being adapted to be selectively inflated between a retracted state and an expanded state in response to the introduction of pressurized fluid into the lumen of the catheter body, the catheter being adapted to be positioned externally of the heart, immediately adjacent to and intermediate the inferior vena cava and coronary sinus ostia during the retrograde administration of cardioplegia solution; and a liquid lubricant for preventing inadvertent adhesion of the interior surface of the inflatable member to the exterior surface of the catheter body, said liquid lubricant being provided on one of the catheter body and inflatable member. - View Dependent Claims (15, 16)
