Catheter System and Method For Occluding A Body Vessel
First Claim
Patent Images
1. An occlusion catheter device for intermittently occluding a coronary sinus, comprising:
- a catheter shaft that carries an inflatable balloon on a distal portion;
a pressure sensor lumen extending centrally through the catheter shaft to a plurality of distal ports that are positioned distally of the balloon for communication with fluid in a coronary sinus;
an inflation lumen to inflate and deflate the balloon;
a stiffening element extending along the catheter shaft, the stiffening element having a distal end portion that is positioned adjacent to the proximal end of the balloon and has a flexural strength reduced relative to a remaining proximal portion of the stiffening element.

Abstract
Some embodiments of a balloon catheter device for introduction into a body vessel, in particular the coronary sinus, can include a catheter shaft which carries an inflatable balloon on its distal portion and in which a plurality of different lumens are formed. In particular embodiments, a system for treating heart tissue can include a coronary sinus occlusion catheter configured for improved deliverability to the coronary sinus and for thereafter performing intermittent occlusion of the coronary sinus.

19. A coronary sinus occlusion catheter device, comprising:
-
a catheter shaft that carries an inflatable balloon on a distal portion; a pressure sensor lumen extending centrally through the catheter shaft to a plurality of distal ports that are positioned distally of the balloon for communication with fluid in a coronary sinus; an inflation lumen to inflate and deflate the balloon; and a balloon pressure-monitoring lumen to measure the pressure in the balloon, the balloon pressure-monitoring lumen being different from and adjacent to the inflation lumen, wherein both the inflation lumen and the balloon pressure-monitoring lumen are in fluid communication with an interior of the balloon.
