| 20120042517 | METHOD FOR MAKING SMOOTH TRANSITIONS BETWEEN DIFFERING LEAD SEGMENTS - A method for forming a lead body includes contacting a proximal section of the lead body having a lumen and a first lead body characteristic to a distal section of the lead body having a lumen and a second lead body characteristic. The proximal and distal sections are contacted such that their lumens are axially aligned. A lap band is disposed about a portion of the proximal section and a portion of the distal section, and is thermally formed to the proximal and distal sections. Axially compressive pressure is applied to the lap band as the lead body is being thermally formed. The pressure applied is sufficient to result in the lead body having an outer diameter in regions proximally and distally adjacent to the lap band that are substantially the same to an outer diameter in a region formed by the lap band. | 02-23-2012 |
| 20100274267 | Medical Clip with Tines, System and Method of Using Same - Device, system and method for drawing together patient tissue. A tether loop is coupled to a first end loop and a second end loop. The first end loop and the second end loop each have an end and are resiliently biased to coil when deployed from a delivery catheter. When positioned within the delivery catheter the first end loop and the second end loop become substantially linear. Upon deployment from the delivery catheter the end loops coil and the first end passes through a first piece of tissue while the second end passes through a second piece of tissue. Each piece of tissue is captured within the corresponding end loop, the coiling of each of which draws the two pieces of tissue together. | 10-28-2010 |
| 20090192562 | CARDIAC RESYNCHRONIZATION VIA LEFT VENTRICULAR PACING - The invention is directed to techniques for providing cardiac resynchronization therapy by synchronizing delivery of pacing pulses to the left ventricle with intrinsic right ventricular depolarizations. An implantable medical device measures an interval between an atrial depolarization and an intrinsic ventricular depolarization is measured. In various embodiments, the intrinsic ventricular depolarization may be an intrinsic right or left ventricular depolarization. The implantable medical device delivers pacing pulses to the left ventricle to test a plurality of pacing intervals. The pacing intervals tested may be within a range around the measured interval between the atrial depolarization and the intrinsic ventricular depolarization. One of the pacing intervals is selected based on a measured characteristic of an electrogram that indicates ventricular synchrony. For example, the pacing interval may be selected based on measured QRS complex widths and/or Q-T intervals. The implantable medical device paces the left ventricle based on the selected pacing interval. | 07-30-2009 |
