First Claim
Patent Images
1. An apparatus, comprising:
- a catheter;
a first inflatable balloon attached to the catheter,wherein the first inflatable balloon is not at or near the distal end of the catheter, andwherein the first inflatable balloon is a tulip-shaped balloon that has an axis and comprises a first section proximal to the user being generally conical along the axis, and a second section distal to the user being generally half-spherical along the axis, anda second inflatable balloon attached to the catheter and distal to the first inflatable balloon,wherein the second inflatable balloon is not at or near the distal end of the catheter.

27. A kit for pericardiocentesis comprising:
-
a catheter for draining the pericardial space; a first inflatable balloon attached to the catheter, for enlarging the pericardial space, wherein the first inflatable balloon is not at or near the distal end of the catheter, and wherein the first inflatable balloon is a tulip-shaped balloon that has an axis and comprises a first section proximal to the user being generally conical along the axis, and a second section distal to the user being generally half-spherical along the axis, and a second inflatable balloon attached to the catheter and distal to the first inflatable balloon, for securing the catheter, wherein the second inflatable balloon is not at or near the distal end of the catheter.
