摘要： A distal section of an implantable medical electrical lead body includes a pair of pre-formed arcuate segments between which an approximately straight segment extends. The approximately straight segment includes a first portion extending distally from a first of the pair pre-formed arcuate segments, a second portion extending from the first portion, a third portion extending from the second to a second of the pair pre-formed arcuate segments. An electrode is coupled to the second portion of the approximately straight segment, and the adjacent first portion has a stiffness which is less than that of the first of the pair pre-formed arcuate segments and preferably less than the stiffness of the third portion, so that, when the distal section of the lead body is implanted, for example, within a cardiac vein, the lead buckles to bring the electrode into closer contact with surrounding tissue.

摘要： An introducer catheter used to deliver an endocardial cardiac electrode has a stylet lumen which collapses upon removal of the stylet to allow for more clearance for the lead and connector to pass when the catheter is removed after lead placement. The collapsible stylet lumen permits the introducer catheter size to be reduced to 8 or 9 French and provide for passage of a 4 French lead.

摘要： An improved medical lead assembly and method of use is provided. The lead assembly includes a lead body, and a spring member positioned adjacent to the lead body. The spring member may be deployed a selectable amount to maintain the lead body in a fixed location within a patient's body. The spring member may be an expandable coil, a mesh structure that is similar to a stent, or any other similar device that may be positioned in a low-profile state during a lead implant procedure. After the lead is positioned at a target destination, the spring member may be deployed an amount that is selected based on the characteristics of the surrounding tissue, including vessel size. According to one aspect of the invention, the lead assembly may provide means for facilitating chronic lead extraction.

摘要： The present invention provides a practical, multi-polar, in-line connector system for use in connecting implantable medical devices (IMD) and associated non-standard, low profile medical electrical leads. In addition, the present invention provides a system that uses tool less, frictional, sealed, compressive electrical connections for most or all of the electrical interconnections between an IMD and a low profile lead. A protective sleeve seals the lead connector to the non-standard port to prevent intrusion of body fluids therein. In addition, optional microchip-based circuitry coupled to the sleeve enables wireless communication and remote programming for diverse IMDs. Memory associated with the circuitry can store, update and reprogram a wide variety of information relevant to the IMD, the patient, and the attending physician, among others. For example, the microchip may be used to identify the lead type and characteristics, as well as other useful data.
