    摘要: An implantable cardiac stimulation lead system for use with a stimulation device includes a lead body preferably having an outer diameter of less than 4 French and formed of a biocompatible material having a Young's modulus of at least 20,000 pounds per square inch. In the lead body, an inner insulator is composed of a suitable polymer such as PTFE or ETFE with an outer peripheral surface formed with a helical groove containing a conductor extending between a proximal connector and a distal tip electrode, and an outer insulator composed of polyurethane or silicone rubber or a combination thereof is positioned around the inner insulator. The lead system may be formed with a lumen for receiving a guidewire longitudinally through the lead body. A pair of insulated conductors may be received in the helical groove, one extending to the distal tip electrode, the other extending to a ring electrode proximally spaced from the distal tip electrode.

    摘要: The intrapericardial lead includes a lead body having a proximal portion and a flexible, pre-curved distal end portion. The distal end portion carries at least one electrode assembly containing an electrode adapted to engage pericardial tissue. The distal end portion further carries a pre-curved flexible wire member having ends attached to spaced apart points along the distal end portion of the lead body, the flexible wire member having a normally expanded state wherein an intermediate portion of the wire member is spaced apart from the distal end portion, and a generally straightened state wherein the wire member and the distal end portion are disposed in a more parallel, adjacent relationship so as to present a small frontal area to facilitate delivery into the pericardial space. The wire member re-expands to its normal state after delivery into the pericardial space to anchor the distal end portion of the lead body relative to the pericardial tissue.

    摘要: An implantable medical lead for transmitting electrical signals between an implantable medical device and selected body tissue comprises a lead body having a distal end portion, a proximal end and an electrically insulating, elongated housing connecting the distal end portion and the proximal end. The proximal end of the lead body carries an electrical connector assembly adapted to be electrically connected to the implantable medical device and the distal end portion of the lead body carries at least one electrode electrically coupled to a terminal contact on the connector assembly. The lead comprises at least one surface susceptible during use of the lead to the accumulation of electrostatic charges, the at least one surface having a coating comprising carbon nanotubes.
