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.

Patent number: 11735068Abstract: An anatomical model for surgical training is provided. The model includes a first layer simulating a liver and a second layer including a simulated gallbladder. A third layer having an inner surface and an outer surface is provided between the first and second layer. The outer surface of the third layer is adhered to the first layer at location around the simulated gallbladder and the simulated gallbladder is adhered to the inner surface of the third layer.

Publication number: 20230010780Abstract: The present invention provides a surgical training device for training laparoscopic first entry surgical techniques. The training device includes a simulated abdominal wall that is penetrable with an optical trocar. A receptacle containing a tissue simulation is located inside the receptacle. The tissue simulation is observable via scope placed inside the optical trocar. Upon penetration of the one or more of the simulated abdominal wall and receptacle, the tissue simulation appears to translate distally relative to the simulated abdominal wall. The distal translation is effected by a variety of ways including the release of negative pressure inside the receptacle upon penetration and the expansion of an elastic wall of the receptacle with the introduction of fluid under pressure into the receptacle.Type: ApplicationFiled: September 20, 2022Publication date: January 12, 2023Inventors: Serene Wachli, Gregory K. Hofstetter, Katie Black, Nikolai Poulsen, Heidi Holmes, Natasha Felsinger, Tracy Breslin, Kennii Pravongviengkham, Boun Pravong, Eduardo Bolanos, Zoran Falkenstein, Charles C. Hart, Tina Talwar

Patent number: 11514819Abstract: A surgical training model that includes a simulated tissue having a tubular shape that is connected to a tissue holder is provided. A portion of the simulated tissue overhangs the distal end of the tissue holder to simulate a cuff-like entry to the vaginal vault or resected intestine suitable for practicing laparoscopic closure of the vaginal vault, intestine or other organ via suturing or stapling. Two concentric tubular structures are also arranged over the same tissue holder. A second model includes two portions of simulated tissue that are held by two holders such that the simulated tissues are adjacent making the model suitable for practicing different types of anastomosis procedures. A third model includes two holders with a single or double tubular simulated tissue structure connected to and spanning a gap between the holders. The model isolates the step of closing a cylindrical opening for the purpose of repeated practice.Type: GrantFiled: January 10, 2020Date of Patent: November 29, 2022Assignee: Applied Medical Resources CorporationInventors: Tracy Breslin, Charles C.

Patent number: 11403968Abstract: A system for training a clinician in energy-based surgical techniques that advantageously does not require the simulated tissue to be electrically conductive is provided. The simulated tissue comprises one or more materials. A heat generator is configured in the shape of a medical instrument typically encountered in energy-based surgical procedures such as electrosurgery or electrocautery. The instrument delivers sufficient heat to melt at least one of the materials in order to simulate energy-based surgical techniques such as excising target material. The one or more materials are configured in the simulated tissue such that their relative thermoplasticity defines a predetermined surgical pathway of a desired clinical outcome.Type: GrantFiled: January 22, 2015Date of Patent: August 2, 2022Assignee: Applied Medical Resources CorporationInventors: Charles C.
