摘要： Disclosed is an improved system and method to selectively promote tissue in-growth on, or adjacent to, an implantable medical device. In one embodiment, at least one surface of the housing of a medical device is in contact with a first portion of a porous PTFE having a pore size adapted to prevent substantially all tissue in-growth. This first portion, or layer, of porous PTFE material is further in contact at predetermined locations with an additional porous PTFE layer having a pore size adapted to selectively promote tissue in-growth only at the predetermined locations. Each of the PTFE layers may be formed of porous PTFE tubing or tape. Alternatively, the two layers may comprise a single composite structure that has a more porous material exposed on a first surface, and a less porous, more dense, material on a second surface. Another embodiment of the invention involves forming the layers of PTFE into a removable member that is adjacent to at least one surface of the implantable medical device. The removable member may take the form of a sleeve that surrounds a portion of a the medical device and is adapted to remain in the body during an extraction process. For example, during the removal of a lead, the sleeve remains within the body and is capable of receiving a replacement lead, making it unnecessary to disturb tissue in-growth attached to the sleeve.

摘要： An improved system and method for deploying medical electrical leads is disclosed. The system includes a guiding device such as a guidewire used to navigate the vascular system of a body. The guiding device includes a fixation member that can be deployed to maintain the guiding device at a desired location within the vascular system. The fixation member may be an inflatable device such as a balloon, or alternatively, may be an expandable device constructed of flexible fibers that has both an expanded and a contracted state. The system may further include a coupling member located adjacent to the guiding device. The coupling member may be a rail extending distally from a proximal end of the guiding device to a point proximal the fixation member. In an alternative embodiment of the invention, the coupling member is a channel included in the body of the guiding device adapted to slidably engage an electrode assembly. The coupling member is adapted to allow the electrode assembly to be slid to the distal end of the coupling member and deployed at a predetermined implant site. In one embodiment of the invention, the coupling member is movable with respect to the guiding device. This allows the coupling member to be re-positioned to multiple implant sites to deploy more than one electrode while the fixation mechanism remains stationary within a patient's vascular system. According to yet another aspect of the invention, the guiding device includes a lumen to delivery fluoro visible medium.

摘要： An implantable device including an elastically compressible member coupled to a distal end of a lead and further coupled to at least one electrode. The compressible member is in a contracted state when the electrode is being delivered to an implant site. At the implant site, the compressible member is expanded to urge the electrode into contact with tissue. Compressible member further includes a keyed structure to engage a stiffening member such as a stylet. The stiffening member is used both to deliver the electrode to the implant site, and to rotate the compressible member, if necessary, so that the electrode contacts predetermined body tissue. According to one aspect of the invention, an introducer having an inner lumen with a diameter that is smaller than that of the compressible member may be used to disengage the stiffening member from the compressible member. In one embodiment, compressible member includes a conductor wound to form multiple turns that are aligned during electrode delivery, but which expand into a non-aligned configuration after deployment. In another embodiment, compressible member includes a spring clip that has a compressed profile during delivery, and an expanded profile after deployment.
