RMED's LockeT Device Utilized in Structural Heart Procedures

Provides Evidence of Efficacy in Large Diameter Sheath Procedures, Expanding Use Beyond Electrophysiology Market

FORT MILL, SC / ACCESSWIRE / July 6, 2023 / Ra Medical Systems, Inc. (RMED:NYSE/American) today announced that its new LockeT device, used as a suture retention device for percutaneous closures, has now been utilized in structural heart procedures. The latest use was in six patients undergoing Watchman & Amulet procedures, where the left atrial appendage is closed off in patients with atrial fibrillation, and two patients receiving the AVEIR Leadless Pacemaker at HCA Trident Medical Center in North Charleston, South Carolina.

HCA Trident Medical Center's Dr. Frank Cuoco, commented, "The LockeT device is another tool in our arsenal that provides ease of use and greatly assists in the femoral closure of the openings from large diameter sheaths. The LockeT allows for greater patient comfort, and hemostasis is achieved in a matter of minutes."

David Jenkins, interim CEO of Ra Medical stated, "Although the electrophysiology market is quite large, we are pleased that the additional evidence of the LockeT use within the structural heart market takes us beyond electrophysiology procedures, and includes not only the LAA device implants, but also the TAVR devices, and certain pacemaker devices such as the AVEIR leadless pacemaker.

Watchman is a product and trademark of Boston Scientific (BSX). AMULET and AVEIR are products and trademark of Abbott (ABT).
