摘要： A cardiac rhythm management system comprises a medical electrical lead, a pressure sensing element, and an implantable pulse generator. The lead is sized to be advanced through the right atrium and coronary sinus into a coronary vein adjacent to the left ventricle. The lead includes an opening intermediate its proximal and distal ends, and a lumen extending longitudinally within the body in communication with the opening. The pressure sensing element is movably disposed in lead lumen and is dimensioned to extend through the opening in the lead, and includes a flexible, elongated conductive member having a distal end, and a pressure transducer coupled to the distal end of the conductive member. The pulse generator is configured to receive cardiac rhythm signals from the electrode and fluid pressure signals from the pressure transducer.

摘要： An implanted medical system includes a medical lead, an anchoring device and at least one suture secured circumferentially about the anchoring device to cause compression of the anchoring device on the medical lead. In particular, the anchoring device is received coaxially over the medical lead and includes an elastomeric sleeve and a compression governor. The elastomeric sleeve has a substantially elongate, hollow, and tubular body. The compression governor is substantially more rigid than the elastomeric sleeve and is coaxially secured to the elastomeric sleeve. The compression governor defines an inner bore having an effective diameter and is adapted to limit compression at a pre-selected minimum effective diameter to limit compressive forces exerted on the lead by the anchoring device.
