AI Technical Summary

Technical Problem

Silicone implants face challenges such as large incisions leading to aesthetically undesirable scars, contamination risks during manual insertion, and capsular contracture, particularly with polyurethane-coated implants, which existing delivery funnels exacerbate due to surface interaction and malposition issues.

Method used

A functionalized implant delivery funnel with a flexible layered body, comprising an outer base layer and a hydrophilic inner coating layer fixed by dipole-dipole forces, forming a lubricating coating, and an adjustable outlet to minimize deformation and reduce contamination risks, while maintaining tissue adhesion with polyurethane-coated implants.

Benefits of technology

The funnel reduces the need for large incisions, minimizes contamination and capsular contracture, and effectively delivers various silicone implants without permanent deformation, enhancing surgical precision and safety.

Abstract

The implant delivery funnel may include a funnel body, a funnel opening, and a funnel outlet, the funnel opening and outlet being located at opposite ends of the funnel body. The funnel body may include an outer base layer and an inner coating layer fixed to the functionalized mating surface of the outer base layer. The inner coating layer may be hydrophilic, forming a lubricating coating with retained water. The funnel opening is sized to receive the implant through the opening without the implant becoming permanently deformed. The funnel outlet has an adjustable size to compress and deliver the implant through the outlet while temporarily reducing its size.
