20090249617 | METHOD FOR MAKING IMPLANTABLE MEDICAL DEVICES HAVING CARBON NANOTUBE-BASED ANTI-ELECTROSTATIC COATINGS - A method of fabricating an implantable medical device having a receptacle adapted to receive a connector assembly attached to a proximal end of an implantable lead. A distal end portion of the implantable lead carries at least one electrode electrically connected with a terminal contact on the connector assembly. The receptacle contains at least one internal insulative sealing surface. An anti-static coating comprising carbon nanotubes is applied to the at least one internal insulative sealing surface. | 10-08-2009 |
20090270741 | Coronary Venous System Pressure Sensing - Disclose herein is a method of measuring pressures in a coronary sinus. In one embodiment, the method includes: introducing a distal portion of a lead or tool into the coronary sinus, wherein the distal portion includes first and second pressure sensors and at least one selectably expandable member; expanding the at least one expandable member such that the first and second sensors are isolated from each other within the coronary sinus; and taking pressure measurements with the first and second sensors when isolated from each other. | 10-29-2009 |
20110137364 | MULTI-SITE PACING FOR ATRIAL TACHYARRHYTHMIAS - Tachyarrhythmia is treated by applying anti-tachycardia pacing through at least one multi-site electrode set located on, in or around the heart. The electrode set is arranged and located such that an electrical activation pattern having a wave-front between substantially flat and concave is generated through a reentrant circuit associated with the tachyarrhythmia. The electrode set may be one of a plurality of predefined, multi-site electrode sets located on, in or around the atria. Alternatively, the electrode set may be formed using at least two selectable electrodes located on, in or around the atria | 06-09-2011 |
20120197141 | IMPLANTABLE ECHO DOPPLER FLOW SENSOR FOR MONITORING OF HEMODYNAMICS - Systems, devices and methods of monitoring blood flow velocity are disclosed herein. For example, one method of monitoring blood flow velocity includes: locating a blood flow velocity sensor near the ostium in the coronary sinus; and sensing towards a portion of the aorta. A second example method includes: locating a blood flow velocity sensor in a vein; and sensing towards an adjacent artery. A third example method includes: locating a blood flow velocity sensor near the tricuspid valve; and sensing towards a tricuspid valve annulus. A fourth example method includes: locating a blood flow velocity sensor right ventricular outflow tract; and sensing towards a portion of the aorta. A fifth example method includes: locating a blood flow velocity sensor in the great cardiac vein; and sensing towards a left anterior descending artery. A sixth example method includes: locating a blood flow velocity sensor in the right atrial appendage; and sensing towards a portion of the aorta. | 08-02-2012 |
