AI Technical Summary

Technical Problem

Existing implantable heart stimulation devices, particularly those implanted subpectorally, prepectorally, or subcutaneously, experience lead deformation due to movement, leading to material fatigue and potential dysfunction, and can cause pacemaker-induced plexopathy by affecting blood flow, posing risks to patients.

Method used

An implantable device that replaces a rib segment, incorporating an anchor and exchange unit with probes, designed to replicate the shape of the removed rib, minimizing soft tissue disruption and using bone integration techniques to stabilize the device, reducing relative movement and lead fatigue, and featuring adjustable joints to absorb shocks.

Benefits of technology

The device reduces lead fatigue and prevents pacemaker-induced plexopathy by stabilizing the implant, promoting bone integration, and allowing for easy battery replacement without additional surgery, thus enhancing patient safety and device longevity.
