Patent number: 11918197Abstract: Systems and methods for tissue containment and retrieval are disclosed. The containment system includes a primary chamber interconnected with a secondary channel extending from the primary chamber. A tissue specimen is mobilized inside a body cavity and placed into the primary chamber through a first opening. The first opening is pulled through a first incision or orifice and the narrower secondary channel is placed at a second incision or orifice. A second opening at the end of the secondary channel permits observation via a scope inserted through the second opening of the tissue specimen in the primary chamber undergoing morcellation via the first opening. Other systems and methods for deployment, containment, debulking and sealing of the second opening to create a closed system for the safe retrieval of the tissue specimen are provided.Type: GrantFiled: October 30, 2019Date of Patent: March 5, 2024Assignee: Applied Medical Resources CorporationInventors: Alexandra Do, Tracy Breslin, Emily Yin, Serene Wachli, Charles C. Hart, Jacob J. Filek

Publication number: 20230397931Abstract: Systems and methods for preventing the seeding of cancerous cells during morcellation of a tissue specimen inside a patient's body and removal of the tissue specimen from inside the patient through a minimally-invasive body opening to outside the patient are provided. One system includes a cut-resistant tissue guard removably insertable into a containment bag. The tissue specimen is isolated and contained within the containment bag and the guard is configured to protect the containment bag and surrounding tissue from incidental contact with sharp instrumentation used during morcellation and extraction of the tissue specimen. The guard is adjustable for easy insertion and removal and configured to securely anchor to the body opening. Protection-focused and containment-based systems for tissue removal are provided that enable minimally invasive procedures to be performed safely and efficiently.Type: ApplicationFiled: August 29, 2023Publication date: December 14, 2023Inventors: Serene Wachli, Tracy Breslin, Steven C. Kessler, Nikolai Poulsen, Nathan Collins, Alexandra Do, Eduardo Bolanos, Boun Pravong, Patrick Elliott, Matthew Wixey, Wayne Young, Jacob J. Filek, Kevin B. Castelo, Adam Hoke, Gregory K.

Publication number: 20230397932Abstract: A guard for providing a cut-resistant pathway through a body orifice or incision to circumferentially protect tissue at the margin is provided. The guard is made of flexible, cut-resistant mesh material having a plurality of interwoven thermosoftening filaments. The guard has a central lumen and at least one flared end. The flared end, which serves to anchor the guard in the body opening, is deformable into a reduced configuration to facilitate its insertion and removal. The layer of mesh stretches laterally to increase the diameter of the central lumen. The flexibility and expandability of the guard allows the guard to conform to body openings of different sizes. The guard may include a drawstring to cinch the flared distal end from the proximal end. The guard is thermoset with the flared distal end that is biased to spring back to its normal, undeformed configuration when released from a deformed configuration.Type: ApplicationFiled: August 30, 2023Publication date: December 14, 2023Inventors: Alexandra Do, Boun Pravong, Serene Wachli

Publication number: 20230321369Abstract: Pressure conditioning systems for supplying insufflation gas to an open-ended body conduit such as a rectal cavity during a transanal minimally invasive surgery (TAMIS) procedure can reduce billowing of walls of the body conduit. A pressure conditioning system can include a pressure storage component, an accumulator, and a flow restrictor. The pressure storage component can include a variable volume reservoir that is biased to a relatively low volume state. The flow restrictor can include insufflation tubing with a restrictor plate having a relatively low diameter orifice. The pressure storage component, accumulator, and flow restrictor can be fluidly connected in various orders in series or as side branches from a gas flow conduit. Despite a pulsed or otherwise discontinuous insufflation gas flow and leakage and absorption from the body conduit, the pressure conditioning system can maintain a constant pressure within the body conduit.Type: ApplicationFiled: April 5, 2023Publication date: October 12, 2023Inventors: Ralph Sias, Alexandra Do, Nikolai Poulsen, Boun Pravong, Kennii Pravongviengkham, Timothy McMorrow, W.F.
