摘要： In an endocardial, active fixation, screw-in lead of the type having a fixation helix adapted to be rotated in a first, advancement direction out of an electrode head chamber and into cardiac tissue by rotation of a lead connector end and attached lead conductor with respect to an insulating sheath in the first direction and retracted into the chamber by rotation of the lead connector in the opposite, retraction direction, a retraction stop mechanism for preventing over rotation of the helix in the retraction direction. The rotational motion of the lead conductor is transmitted to the helix by a connecting assembly and is translated into axial advancement and retraction of the helix by a guide cooperating with the helix turns. A retraction stop mechanism stops rotation of the helix in the retraction direction upon full retraction of the helix into the chamber and allows rotation of helix in the advancement direction. The retraction stop mechanism includes a fixed stop formed of a plurality of fixed cam and axial stop surfaces surrounding a proximal end bore of the chamber through which the lead conductor passes and a movable stop formed in the connecting mechanism of a like plurality of rotatable cam and axial stop surfaces aligned to face the fixed cam and axial stop surfaces adapted to engage in a locked relation of the stop surfaces upon full retraction of the fixation device into the chamber.

摘要： A lead connector arrangement includes a non-cylindrically shaped connector pin coupled to a lead conductor and a connector sleeve assembly for receiving the non-cylindrically shaped connector pin. The connector sleeve assembly includes an insert with an axial bore formed therein that complements the shape of the non-cylindrical connector pin. According to one embodiment, the non-cylindrical connector pin may be provided in the form of a triangular, square, rectangular, or hexagonal shape. The axial bore has a complimentary shape to receive the connector pin. When the connector pin is threaded through the connector sleeve assembly using a pull-wire device, the pull-wire device may be unscrewed from the connector pin without causing axial rotation of the lead conductor when the connector pin is fully inserted within the axial bore.

摘要： An implantable electrode of the type in which an elongated wire coil forms the electrode surface. The electrode coil is mounted around an insulative lead body and is stabilized on the lead body by means of a plastic filler between the individual turns of the electrode coil, extending radially outward to approximately one-third of the diameter of the electrode coil wire. The filler is produced by stretching a portion of the lead body which normally displays an outer diameter greater than the inner diameter of the electrode coil, sliding the electrode coil over the lead body and inserting a mandral into the lead body to urge the lead body into contact with the electrode coil. This assembly is heated to encourage flow of the lead body into the spaces between the electrode coil to stabilize the coil on electrode body and to prevent fibrotic ingrowth around the electrode coil wire.
