Patent number: 11614170Abstract: A new system for negative pressure wound therapy is described. The system includes a patient tube set connecting the wound dressing to the suction container. The patient tube set provides separate channels for applying suction to the wound site and sensing the therapeutic pressure at the wound site. A restrictor valve may also be included in order to introduce a small air leak into the system to prevent occlusions in the patient tube set.Type: GrantFiled: May 8, 2020Date of Patent: March 28, 2023Assignee: Innovative Therapies, LLCInventors: David Malcolm Tumey, Tianning Xu, Alan John Martin, Brent Lee Burchfield, Raymond Reade Harpham

Patent number: 10814047Abstract: Fluid collection systems and methods are disclosed which may utilize suction to draw fluids into containers for storage and eventual disposal. The system may utilize rigid or semi-rigid canisters to provide a chamber in which fluids may be collected under negative pressure, stored, and transported. The system may utilize disposable or reusable flexible, semi-rigid, or rigid liners for isolating fluid and liquid waste from the walls of the canister. In various embodiments, either a single canister assembly or multiple canister assemblies are mounted to a manifold, the manifold being configured to support each canister assembly and/or provide a connection to a source of suction for each canister assembly.Type: GrantFiled: April 25, 2017Date of Patent: October 27, 2020Assignee: ALLEGIANCE CORPORATIONInventors: Raymond Reade Harpham, Brent Lee Burchfield, Kok Hern Law, Rajesh Gladwin Dharmadas, Wei Chen Lie, Robert John Weinberg, Stephany Chang, Stacey Hoebel Burgardt, Matthew Michael Bruggeman, David James Stroud, Talya Mathein

Publication number: 20140050423Abstract: A biodegradable lawn waste collection system is provided. The system generally includes a waste receiver, a shaping insert, and a handle. The waste receiver may comprise a mesh structure having a filling end and a sealing end. The mesh structure may be formed from a biodegradable polymer composition. The shaping insert is configured for removable reception within the filling end of the waste receiver. The shaping insert provides the waste receiver with rigidity and stability when filling the waste receiver with lawn waste. After the waste receiver has been filled with lawn waste, the shaping inert is removed and the filling end is secured, such as by tying a knot. The full waste receiver is then releasably attached to the handle, which enables the full waste receiver to be easily carried or dragged to a desired destination.Type: ApplicationFiled: August 19, 2013Publication date: February 20, 2014Applicant: Green Bag, LLCInventors: Brent Lee Burchfield, Ryan Scott Crisp, Eric James Fickas, Paul Perry Kolada, Michael Anthony Lorenz, Donald Collins Meves, Shannon Staats, Herman Jones

Patent number: 8574253Abstract: A method and device for tissue removal. The device may be used to remove uterine fibroids and other abnormal gynecological tissue. According to one embodiment, the device includes a housing, an outer tube, and an inner tube. The outer tube is fixed to the housing and includes a side window proximate to its distal end. The side window may have sloped proximal and distal ends. The inner tube has a distal end positioned within the outer tube, the distal end being adapted to rotate and, at the same time, to move back and forth past the side window, with the rotational and translational movement of the inner tube being independently controllable. The distal end of the inner tube may have an external bevel. Suction is applied to the proximal end of the inner tube to draw tissue into the side window and to remove resected tissue through the inner tube.Type: GrantFiled: April 4, 2008Date of Patent: November 5, 2013Assignee: Hologic, Inc.Inventors: William Harwick Gruber, Ronald David Adams, Albert Chun-Chi Chin, Eric Karl Litscher, Roy Hewitt Sullivan, Paul DiCesare, Jeffrey Radziunas, Daniel Vigliotti, Bryan Dale Knodel, Chris Scott Daniels, Kevin J.
