Abstract
This document describes methods and devices for securing epicardial devices. For example, this document describes methods and devices for securing epicardial devices by passing a sheath into a pericardial space of a patient through a first percutaneous access site, passing a guidewire through the sheath into the pericardial space of the patient, passing the guidewire through a transverse sinus of the patient, passing a snare device into the pericardial space through a second percutaneous access site, and capturing a free end portion of the guidewire using the snare device.
Claims11
A method of securing an epicardial device, the method comprising:
- passing a sheath into a pericardial space of a patient using a first percutaneous access site;
- inflating a balloon on the sheath;
- passing a guidewire comprising a first end and a second end into the balloon using a second percutaneous access site;
- capturing a free end of the guidewire using a snare device in the balloon;
- threading the epicardial device over the guidewire to be positioned near the epicardial surface;
- and
- securing the first end and the second end of the guidewire to a hole, a slot, or a notch defined by a cap configured to abut an apex of a heart of the patient such that the guidewire forms a loop that begins and ends at the cap,
- wherein the guidewire comprises one or more denuded portions that are configured to function as one or more electrodes, and
- wherein the epicardial device comprises a defibrillator coil.
