AI Technical Summary

Technical Problem

Existing technologies for manufacturing microfiber surgical implants, such as those used for soft tissue repair, face challenges including high variability, limited porosity leading to poor cell infiltration, use of harmful processing solvents, complexity in scaling, and high manufacturing costs, and inability to mimic the natural structure or strength of tissues.

Method used

A microfiber inkjet printer is used to manufacture microfiber implants by winding microfilaments on a device with a winding platform, applying a coating, and heating to fuse regions, allowing for the creation of microfiber patches that can be further processed to form implants with structural integrity and biological compatibility.

Benefits of technology

The method produces microfiber implants with enhanced structural strength and biological compatibility, facilitating better tissue integration and repair, with improved cell infiltration and mechanical properties comparable to natural tissues.

Abstract

A method for manufacturing a microfiber implant. The method includes a winding platform and The method uses an apparatus consisting of a feeder head, which is connected to a winding plug. Advance the microfilament towards the take-up platform and wrap it around the The feeder head is then rotated to the position where the microfilament is being wound. The feeder head moves laterally relative to the winding platform. Multiple sweeps can be performed to build up layers of coating, resulting in microfabrication. A fiber patch is obtained, which is then further processed (e.g., by applying a collagen coating). This winding technology creates a microfiber implant. Microfiber implants and devices for winding are also disclosed.
