摘要： A single-pass endocardial lead electrode adapted for implantation in, on or about the heart and for connection to a system for monitoring or stimulating cardiac activity includes a lead body which is adapted for implantation within a single chamber of the heart, or multiple chambers of the heart. The lead includes a first distal end electrode which has a first electrical conducting surface. The lead body also has a second electrode which has a second electrical conducting surface. The first and second electrodes are either passively or actively attached to the wall of the heart. The lead body also includes a curved portion which facilitates the positioning of the second electrode. The main lead body alternatively includes a recess into which an atrial lead body and an active fixation element attached to one end can travel from a recessed position to a position for fixation to the wall of the heart. The active fixation element can also be moved by turning the terminal pin. The lead body can also include multiple legs, each leg carrying an electrode. The lead is attached to a pulse generator for producing pulses to the multiple sites within the heart. A movement assembly for advancing a helix is also included within the legs and comprises an externally threaded collar which engages with an internally threaded housing or housing insert. The lead further includes a helical tip which has high impedance. The electrode has at least one features of the group: the helix having a coating of an insulating material on its surface, the helix having its surface beyond the distal end of the electrode and the distal end of the electrode having a porous conductive surface at a base of the helix, a porous conductive element at a base of the helix, and a porous conductive element at the end of the electrode having an insulating coating cover from 5-95% of the surface of the porous conductive element. The porous element may further provide a guiding mechanism for the helix as it travels out of the electrode for securing the electrode to the heart.

摘要： An endocardial lead comprising an elongate body having a first defibrillation coil electrode, a second defibrillation coil electrode and a first pacing/sensing electrode. The first defibrillation coil electrode has a first end and a second end, where the first end is at or near the distal end of the elongate body and the second end spaced longitudinally from the distal end. The first pacing/sensing electrode is spaced longitudinally along the peripheral surface from the second end of the first defibrillation coil electrode. The second defibrillation coil electrode is spaced longitudinally along the peripheral surface from the first pacing/sensing electrode to afford positioning the first defibrillation coil longitudinally adjacent an apical location of the right ventricle of a heart with the first pacing/sensing electrode within the right ventricle of the heart and the second defibrillation coil within the right atrial chamber or a major vein leading to the right atrial chamber of the heart. The elongate body further includes a curved portion on which the first pacing/sensing electrode is positioned such that the first pacing/sensing electrode extends beyond the peripheral surface of the elongate body to engage the tissue of the heart. The first pacing/sensing electrode further includes a retaining element, where the retaining element is adapted to be embedded in the right ventricle of the heart to secure the first pacing/sensing electrode and the elongate body of the endocardial lead to the right ventricle of the heart.

摘要： A cardiac rhythm management system provides an endocardial cardiac rhythm management lead with an at least partially dissolvable coating at least partially on insulating portions of the lead body at or near its distal end. Upon dissolution, the coating promotes tissue ingrowth to secure the lead in place within fragile vascular structures or elsewhere. Dissolution of one such coating releases a therapeutic agent, such as a steroid that modifies the fibrotic scar tissue content of tissue ingrowth, such that the resulting bond between the tissue and the lead is weak, so that the lead can be easily extracted if desired. One such lead includes an insulating elongate body carrying at least. The lead also includes an at least partially dissolvable coating on an insulating portion of the peripheral distal lead surface. The coating provides one or more of a rough surface, a porous surface, or a swollen surface after being exposed to an aqueous substance.
