Publication number: 20240041552Abstract: Tissue expansion system includes a pump, a controller, and inflatable bladder, and a pressure sensor. The pump is adapted for substantially continuous operation in response to a pressure within a subcutaneously implanted inflatable bladder. The pump is thus able to deliver inflation medium to the bladder when the pressure within the bladder is below a predetermined lower threshold while stopping delivery of the fluid when the pressure rises above a higher threshold or reaches a predetermined maximum volume.Type: ApplicationFiled: March 17, 2023Publication date: February 8, 2024Inventor: Joshua Korman

Publication number: 20230029422Abstract: A tissue expansion system includes an expandable bladder for placement beneath the skin corresponding to a tissue to be expanded, a fluid source, a pump coupled to both the fluid source and the expandable bladder to deliver inflation medium thereto, a controller for the pump, a pressure sensor for monitoring pressure within the expandable bladder and informing the action of the controller, and a carrier for holding at least the fluid source, pump, and controller. The carrier is wearable as a bra or form-fitting vest and is shaped to mimic the appearance of natural breasts for the patient. The fluid source can have an outward facing surface that is relatively rigid to maintain a curved shape mimicking that of natural breast(s). The inward facing surface of the fluid source may be flexible to conform to the shape of the underlying skin and tissue as it is expanded.Type: ApplicationFiled: October 3, 2022Publication date: January 26, 2023Inventor: Joshua KORMAN

Publication number: 20160242865Abstract: A tissue expansion system includes driver assembly having a syringe pump and a controller held in a common enclosure. The driver assembly is connected to both an inflatable bladder and an inflation medium source. Fluid is delivered from the driver assembly to the inflatable bladder through a pressure sensor. The pump is actuated to deliver predetermined incremental volumes of the inflation medium to the inflatable bladder at spaced apart time intervals. Pressure is monitored and the pumping is interrupted if the pressure exceeds a predetermined high threshold value. Pumping is recommenced when the pressure falls below a lower threshold value until the total incremental delivery volume has been reached.Type: ApplicationFiled: May 5, 2016Publication date: August 25, 2016Inventor: Joshua KORMAN
