AI Technical Summary

⚠Technical Problem

Current temporary transvenous pacing leads face challenges such as high risk of myocardial perforation, dislodgement, require fluoroscopic guidance for placement, and are costly due to complex manufacturing and actuator mechanisms, limiting their use to interventional specialists.

⚗Method used

A self-expanding temporary pacing lead with an enclosed loop at the distal end, featuring a biasing member that expands to form a stable, atraumatic contact with the endocardial surface, allowing fluoroscopy-free placement and bedside deployment by non-interventional physicians, reducing manufacturing complexity and cost.

🎯Benefits of technology

The self-expanding design reduces myocardial perforation risk, dislodgement rates, and radiation exposure, enabling easy, cost-effective placement and repositioning without fluoroscopy, suitable for various clinical settings.

Abstract

Apparatus and related methods relate to a self-expanding temporary pacing lead. In an illustrative embodiment, a temporary pacing lead may include an enclosed loop at a lead distal end. The enclosed loop may form a permanently closed perimeter. The enclosed loop may, for example, include a biasing member having an expanded equilibrium shape. The biasing member may urge the enclosed loop to an expanded configuration. The enclosed loop may have at least a first electrode site located on a first side of a linear loop axis. For example, at least a second electrode site may be located on a second side of the linear loop axis. The first electrode site and the second electrode site may be spatially distributed along a distal portion of the enclosed loop. Various embodiments may advantageously provide a safe, easy to use, and cost-effective temporary pacing lead.
