| 20090131873 | SYSTEM AND METHOD FOR POSITIONING IMPLANTABLE MEDICAL DEVICES WITHIN CORONARY VEINS - An improved system and method for placing implantable medical devices (IMDs) such as leads within the coronary sinus and branch veins is disclosed. In one embodiment, a slittable delivery sheath and a method of using the sheath are provided. The sheath includes a slittable hub, and a substantially straight body defining an inner lumen. The body comprises a shaft section and a distal section that is distal to, and softer than, the shaft section. A slittable braid extends adjacent to at least a portion of one of the shaft section and the distal section. In one embodiment of the invention, the sheath further includes a transition section that is distal to the shaft section, and proximal to the distal section. The transition section is softer than the shaft section, but stiffer than the distal section. | 05-21-2009 |
| 20090198298 | METHODS AND SYSTEMS FOR USE IN SELECTING CARDIAC PACING SITES - A method and system for use in selecting a cardiac pacing site includes sensors for tracking wall motion (e.g., sensors coupled to the right and left ventricular heart wall). The wall motion of one or more non-paced cardiac cycles is compared to the wall motion of one or more paced cardiac cycles to determine the effectiveness of one or more pacing sites. For example, image data may be generated to notify the user as to the effectiveness of the one or more pacing sites. | 08-06-2009 |
| 20090264862 | MEDICAL DELIVERY DEVICE CONSTRUCTION - A delivery device includes an outer sidewall and an inner sidewall extending therein.
