The present invention relates to a stimuli-responsive hydrogel in which the timing of swelling is controllable by external stimuli, to a tissue expander using same, and to a method for using the tissue expander comprising same.

A method of removing fluid from breast tissue surrounding a tissue expander includes identifying a location of an injection port of a tissue expander, and obtaining a needle including a needle shaft defining a lumen, the needle including a closed tip at the distal end of the needle shaft and at least one lateral opening formed in an outer wall of the needle shaft that is in fluid communication with the lumen. The method includes inserting the closed tip of the needle through skin of the patient, the breast tissue, and the injection port until the closed tip of the needle contacts a needle guard, visually confirming that the at least one lateral opening of the needle is not located outside of the patient's skin, and aspirating fluid from the breast tissue via the at least one lateral opening of the needle.

To provide a tissue expander that can prevent excessive pressure that collapses capillary circulation and reduce shear stress generated at skin junctions. The tissue expander includes a shell, an opening in the shell that communicates with an external vacuum source for applying a vacuum within the shell to provide a distraction force to expand tissue, and a rim coupled to the shell and adapted to contact the patient's skin, the rim being non-fixedly attached to the patient's skin and adapted to move laterally outwardly relative to the shell under application of vacuum.

Provided are a tissue expander and a method for using same, the tissue expander comprising: an elastic shell; an injection port provided on the surface thereof; and a sealing member provided on the surface of the elastic shell, surrounding the injection port, wherein the sealing member comprises a scattering agent.

An implant insertion system including a tissue expander or separator including an inflatable balloon with a curved posterior side when inflated and an implant having a curved posterior side when positioned against an anatomical surface, wherein the curved posterior side of the implant substantially matches the curved posterior side of the tissue expander. The implant can have an anterior side substantially similar to the posterior side. The implant insertion system can have an injector configured to insert the implant into a target location.

A doctor can quickly change the matched expansion plate according to actual requirements, the accuracy and adaptability of surgical operation are improved, and meanwhile, when the equipment is transported and stored, the equipment is convenient to disassemble, space occupation is reduced, and transportation difficulty and cost are reduced.

This disclosure relates generally to electrically stimulating dilators for selectively stimulating nerves during surgical procedures. A dilator for use in surgery includes a body extending from a proximal end to a distal end, with a clip attachment area at the proximal end of the body for receiving a stimulating clip. The clip attachment area includes an anterior electrode and a posterior electrode, the anterior electrode and posterior electrode insulated from each other. The dilator also includes a first conductive pathway extending from the anterior electrode to the distal end of the body and a second conductive pathway extending from the posterior electrode to the distal end of the body. An anterior emitter is at a distal end of the first conductive pathway and a posterior emitter is at a distal end of the second conductive pathway, with the posterior emitter disposed opposite the anterior emitter.

A tissue expander comprising: a port assembly including a drain port and a fill port, a magnet housing assembly fitted to the port assembly, the magnet housing assembly including a single magnet having a magnetic field that is detectable on an exterior surface of a biological tissue of a patient; a shell defining the interior cavity of the tissue expander; and a drain assembly in fluidic communication with the drain port via the drain tubing.

A tissue expander includes a shell defining an interior cavity, a first port in fluid communication with the interior cavity, a second port, and a magnet. The magnet is positioned along an axis extending through the first port and the second port. The magnet produces a magnetic field to enable location of the first port and the second port.
