Abstract

Prosthetic Support NU 2010-142-02 Inventor John Kim Abstract Breast reconstruction surgeon Dr. John Kim has developed a novel matrix to assist with tissue expander-based reconstruction. In the last 5 years, there has been a surge of interest in using acellular dermal matrix (ADM) to enhance traditional tissue expander-based breast reconstruction. The technique involves releasing the pectoralis muscle and using the ADM to fashion a supportive lower pole "sling." The reported benefits of this technique include enhanced position, shape, and symmetry of the breast as well as more rapid expansion and potentially a reduced capsular contracture rate. As more prophylactic mastectomies are done--especially nipple-sparing versions--the ability to use ADM has allowed reconstructive outcomes for expander or direct-to-implant reconstructions to start approaching the outcomes of the more complex autogenous flap based procedures. While the integration of this new technology platform with the modified expander technique has gained substantial traction among plastic surgeons, there have been some dissenting specters of cost and safety raised. Specifically, the ADM is harvested from human or animal donors and the issue of disease transmission and sterility have been raised. Moreover, the product is imbued with a high cost secondary to this involved procurement and processing. This invention is an absorbable implant device of similar dimension and physical characteristics of ADM. It is made of suture material that is already commonly used in surgery (PDS-polydiaxosilane) and therefore both well-tolerated and absorable and easily manufactured in cost-effective fashion. Applications o Sling for mammary prosthesis in patients undergoing breast reconstructive surgery. o Breast cancer o Breast enlargement Advantages o An implant that replicates the function of tissue-based acellular dermal matrix o Cost-Effective o Safe (non-tissue based and sterile) Marketing Contact Maryam Saleh, PhD Invention Manager (e) maryam-saleh@northwestern.edu (p) 847-467-3095
