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 implantable lead, being either a fixed or retractable/extendable lead, having a distal tip electrode is adapted for implantation on or about the heart and for connection to a system for monitoring or stimulating cardiac activity. The electrode includes a mechanical fastener such as a fixation helix for securing the electrode to cardiac tissue, which may or may not be electrically active. The implantable electrode with a helical tip includes an electrode which has a distal end and a proximal end. A helix is disposed within the electrode, where the helix is aligned along a radial axis of the electrode. The electrode further includes one or more of the following features: the helix having a coating of an insulating material on a surface of the helix, a porous conductive surface at a base of the helix, a porous conductive element at the end of the electrode having an insulating coating covering from 5-95% of the surface of the porous conductive element. The electrode may farther include an electrode tip having a porous electrical conductive element, such as a mesh screen, disposed on a surface at the distal end of the electrode tip, which can be used as a sensing or pacing interface with the cardiac tissue.

摘要: An implantable lead, being either a fixed or retractable/extendable lead, having a distal tip electrode is adapted for implantation on or about the heart and for connection to a system for monitoring or stimulating cardiac activity. The electrode includes a mechanical fastener such as a fixation helix for securing the electrode to cardiac tissue, which may or may not be electrically active. The implantable electrode with a helical tip may comprise: an electrode having a distal end and a proximal end; and a helix disposed within the electrode, which helix is aligned along a radial axis of the electrode to the distal end; and the implantable electrode having at least one feature selected from the group consisting of: a) the helix having a coating of an insulating material on its surface, b) 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, c) a porous conductive element, screen or mesh at a base of the helix, and d) a porous conductive element at the end of the electrode having an insulating coating covering from 5-95% of the surface of the porous conductive element. The electrode may further include an electrode tip having a porous electrical conductive element, such as a mesh screen, disposed on a surface at the distal end of the electrode tip, which can be used as a sensing or pacing interface with the cardiac tissue. The porous electrically conductive element will usually be positioned at the base of the helix (when extended if extendable/retractable). The mesh or screen may provide a guiding mechanism for the helix as it travels out of the electrode for securing the electrode to the heart or other muscle or organ. The guiding mechanism may include a groove within the mesh screen. Alternatively, the guiding mechanism includes a guiding bar on which the fixation helix rides on during extension or retraction. In combination with each of these high impedance tips, a drug delivery system is provided at least the majority of which drug delivery system is provided from a source within a volume which is within the structural walls of the lead and/or within a volume having its major dimensions and/or at least 50% of its volume generally within the projected area of the tip.

摘要: A pacing lead for a cardiac stimulator that includes an elongated flexible insulating lead body. An electrode is attached to the lead body at its distal end. An elongated conductor extends through a lumen of the elongated lead body for connecting the electrode to the terminal pin. The conductor is in the form of a coiled wire until it reaches approximate the electrode. It is then crimped to a cable conductor which in turn is crimped or welded to the electrode. The electrode is supported at the distal end by a molded support body which includes a lumen for a guide wire.
