Sponsor

Tensive SRL

Enrollment

92 participants

Start Date

Sep 29, 2023

Study Type

INTERVENTIONAL

Conditions

Mastectomy, Segmental Breast Neoplasm Malignant Female

Summary

The goals of this clinical trial are: * demonstrate the safety of REGENERA breast implant in patients undergoing lumpectomy of malignant breast lesions * demonstrate the safety and performance of REGENERA in terms of investigator's satisfaction, potential interference with current standard-of-care imaging techniques and occurrence of device-related serious adverse events.
