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： Methods and endocardial screw-in leads for enabling provision of electrical stimulation to the heart, particularly the His Bundle in the intraventricular septal wall. An endocardial screw-in lead having a distal end coupled to a retractable fixation helix wherein a distal portion of the fixation helix extends beyond the lead distal end when the fixation helix is fully retracted or partially extended is positioned in proximity to the His Bundle in the septal wall. The lead body is rotated to attach the distal portion of the fixation helix into the septal wall. The fixation helix is rotated with respect to the lead body to fully extend the fixation helix so that a portion of the fixation helix is in proximity to the His Bundle, enabling provision of electrical stimulation to the His Bundle and/or to sense electrical signals of the heart traversing the His Bundle through the fixation helix.

摘要： A medical electrical lead including an inflatable member at a distal tip section, and a system of use, are disclosed. The inflation member is adapted to engage the walls of a cardiac vein or coronary artery to occlude the vessel. According to one aspect of the invention, the inflation member is formed of a bio-absorbable material. In another embodiment, the inflation member is a micro-porous material. The lead of the current invention may include a port located distal to the inflation member to deliver radiopaque dye or any other substance to a vessel when the inflation member is in the inflated state. This allows a fluoroscopic image of a patient's vascular system to be obtained while the lead is in place within a vessel. A perfusion lumen may be provided to allow a partial flow of blood to continue around the inflation member when the inflation member is occluding a vessel. In one embodiment, lead is provided with a lumen for receiving a stiffening member such as a stylet to aid in lead placement. According to one method of using the current invention, inflation member may be inflated after the lead is placed at a desired implant site to provide a temporary fixation mechanism during withdrawal of the stiffening member and/or a guide catheter or sheath used to place the lead at the implant site. This temporary fixation mechanism may also be employed to retain a desired lead location while thresholds are obtains. The inflation member may be retained in an inflated state for a longer predetermined period of time until tissue in-growth begins to occur around the lead.

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.
