    摘要: A medical device lead is presented. The lead includes one or more jacketed conductive elements. The jacket comprises one or more covers. A first cover of polyether ketone (PEEK) is in direct contact with the at least one conductive element. At least one conductive element and a PEEK cover are coiled. The coiled conductive element can substantially retain its original coiled shape.

    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: A lead and a lead system for dispersion of a cardioversion/defibrillation electrode formed of one or more small diameter defibrillation electrodes in a heart chamber and for attaching a pace/sense electrode in contact with the heart. The small diameter defibrillation electrode or electrodes extend distally from the distal end of the lead body. If multiple electrodes are employed, they are preferably biased to spread apart when unrestrained and have a cross-section size small enough to be inserted into interstices of trabeculae in the ventricular chamber. The distal ends of the defibrillation electrodes may be free of attachment to the lead body or may be attached by a weak bond to the distal portion of the lead.
