Patent number: 7499758Abstract: Subcutaneous leads that incorporate active fixation elements including, for example, helical coils, provide for fixation of cardiac lead components within a patient. An implantable lead includes a lead body with a supported electrode configured for subcutaneous non-intrathoracic placement within a patient. A fixation element is provided on the implantable lead and configured to actively secure one or both of the subcutaneous electrode and the lead body in tissue. A delivery apparatus comprising a sheath may be employed that is configured to introduce the lead to a desired subcutaneous non-intrathoracic location. Lead delivery typically involves introducing a sheath into a subcutaneous non-intrathoracic body location of a patient, providing a lead supporting an electrode, advancing the lead through the sheath, actively fixing the lead to tissue, and thereafter removing the sheath from the patient.Type: GrantFiled: December 18, 2003Date of Patent: March 3, 2009Assignee: Cardiac Pacemakers, Inc.Inventors: Adam W.
