Acute and chronic fixation for subcutaneous electrodes
First Claim
1. An implantable lead, comprising:
- a lead body;
a cardiac electrode supported by the lead body, the cardiac electrode configured for subcutaneous non-intrathoracic placement within a patient;
an acute fixation element provided on the implantable lead, the acute fixation element configured to acutely secure one or both of the lead body and the cardiac electrode to the subcutaneous non-intrathoracic tissue; and
a chronic fixation element provided on the implantable lead, the chronic fixation element configured to chronically secure one or both of the cardiac electrode and the lead body in the subcutaneous non-intrathoracic tissue.

Abstract
Implantable subcutaneous devices and methods incorporating a lead and/or electrode for cardiac monitoring and intervention, the lead employing chronic fixation elements including, for example, ridges, grooves, surface roughness, porosity, combined with acute fixation elements such as, for example, a suture site. A method of implanting subcutaneous leads may involve providing a lead comprising a lead body, an electrode, an acute fixation element, and one or more chronic fixation elements, and securing one or both of the lead body and the electrode to subcutaneous non-intrathoracic tissue at one or more fixation sites using the fixation elements. The method may involve: introducing a sheath into a subcutaneous non-intrathoracic body location of a patient; providing a lead comprising a lead body and an electrode; advancing the lead through the sheath and to the subcutaneous non-intrathoracic body location; fixing the lead to subcutaneous non-intrathoracic tissue; and removing the sheath from the patient.
