Bionic Breast Project Using a Neuroprosthetic Device to Restore Touch and Reduce Chronic Pain After Mastectomy

What this Trial Is About

Researchers are investigating whether touch sensation can be restored to the breast after mastectomy using neural stimulation. This trial aims to gather information to guide future studies on the safety, effectiveness, and acceptability of this approach. The study focuses on women undergoing bilateral mastectomy with two-stage reconstruction for certain types of breast cancer or breast cancer risk reduction. Participants will receive a small medical device called the Bionic Breast implant, temporarily placed in one breast during the mastectomy. This device sends tiny electrical currents to nerves to create sensory stimulation in response to touch or pressure. The device will later be removed, and the study will assess the sensations produced by the stimulation. During the study, participants will complete psychophysical tasks seven months after mastectomy, implantation, and device removal to evaluate sensation and stimulation levels. Researchers will measure outcomes such as stimulation intensity, ability to distinguish different stimuli, and mapping of sensation areas. Participants will be monitored throughout for safety and adherence, with the total study duration spanning several months post-surgery.
