    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: 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.
