Abstract
A lead includes a lead body and an electrode disposed proximate a distal end of the lead body. A retaining member is disposed proximate the distal end of the lead and adapted to retain the electrode proximate an interatrial septum when the retaining member is located on a left atrial side of the interatrial septum.
Claims40
A lead comprising:
- a lead body extending from a proximal end to a distal end and having an intermediate portion;
- an electrode disposed proximate the distal end of the lead body;
- and
- a retaining member disposed proximate the distal end of the lead and adapted to retain the electrode proximate an interatrial septum when the retaining member is located on a left atrial side of the interatrial septum.

A lead comprising:
- a lead body extending from a proximal portion to a distal portion and having an intermediate portion;
- an electrode disposed proximate the distal portion of the lead body;
- and
- a retaining member disposed proximate the distal portion of the lead, the retaining member having an expanded orientation having a larger outer diameter than a diameter of the distal portion of the lead body.
1 more element
A lead comprising:
- a lead body extending from a proximal end to a distal end and having an intermediate portion;
- a shocking electrode disposed proximate the distal end of the lead body;
- and
- a retaining member disposed on the lead body and located distally from the shocking electrode, wherein the lead body includes a pre-biased curved section between the shocking electrode and the retaining member.
1 more element
A method comprising:
- inserting a distal tip of a lead through an interatrial septum;
- deploying a retaining member on the lead on a left atrial side of the interatrial septum such that an electrode on the lead contacts the interatrial septum;
- and
- delivering energy pulses to the interatrial septum via the electrode.
1 more element
A method comprising:
- inserting a distal tip of a lead through an interatrial septum;
- deploying a retaining member on the lead on a left atrial side of the interatrial septum;
- providing a curved section on the lead so as to bias an electrode disposed on the lead towards a right atrial side surface of the interatrial septum;
- and
- delivering energy pulses to the interatrial septum via the electrode.
