摘要： An implantable myocardial stimulation lead comprises a lead body having a distal end and a proximal end, and an electrical connector carried by the proximal end of the lead body. An electrode header carried by the distal end of the lead body has an axis and includes a helical fixation element extending along the axis, the electrode header having a surface configured to receive a driver for rotating the electrode header to screw the helical fixation element into the tissue of the heart. The lead body carries along its length a strain relief member resisting excessive bending of the lead body.

摘要： A chamber or vasculature of a heart may be accessed via the pericardial space of the heart. Initially, the pericardial space may be accessed via a transmyocardial approach or a subxiphoid approach. A lead or other implantable apparatus may thus be routed into the pericardial space, through myocardial tissue and into the chamber or vasculature. The lead or other apparatus may be used to sense activity in or provide therapy to the heart.

摘要： A delivery apparatus for accessing the pericardial space of a heart including an elongated body defining a lumen and a piercing member that extends from a distal portion of the elongated body for piercing tissue of the heart. A spring expands from a distal end of the piercing member in response to the distal end of the piercing member passing through the tissue and into the pericardial space. An electrode located on the spring in order to sense signals indicative of a distal end of the spring passing through the tissue and into the pericardial space.

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.
