Patent number: 10595890Abstract: A minimally invasive laparoscopic tissue removal device, namely a morcellator. The device includes, from proximal end to distal end, a handle, handle guard, elongate sheath, and mouth, finally terminating in a safety tip. The elongate sheath and mouth are concentric, such that two elongate, rotating cutting/shredding blades/teeth and one elongate auger feed screw can be positioned along the length of the sheath and mouth. The teeth are opposingly disposed and staggered, such that contact with tissue mass grabs and pulls tissue inwards toward the auger, which transports the tissue proximally toward the outside of the patient's body. A motor unit and gear assembly can be coupled to the teeth and auger to drive rotation of the teeth and auger. A cup assembly can be disposed in overlying relation to the mouth for guiding the tissue mass towards the mouth. Various mechanisms of safely covering the mouth are contemplated as well.Type: GrantFiled: November 30, 2017Date of Patent: March 24, 2020Assignee: University of South FloridaInventors: Stuart Richard Hart, Erik James Esinhart, Adam Thomas Lytle, Daniel Ryan Kamsler, Charles William Drake, III, Yasin Ahamed Junaideen, Mario Alves Simoes

Patent number: 10593035Abstract: A system and methodology for the automated localization, extraction, and analysis of MRI-based features with clinical information to improve the diagnosis of pelvic organ prolapse (POP). The system can automatically identify reference points for pelvic floor measurements on MRI rapidly and consistent. It provides a prediction model that analyzes the correlation between current and new MRI-based features with clinical information to differentiate patients with and without POP. This system will enable the high throughput analysis of MR images for their correlation with clinical information to better detect POP. The presented system can also be applied to the automated localization and extraction of MRI features for the diagnosis of other diseases where clinical examination is not adequate.Type: GrantFiled: March 18, 2016Date of Patent: March 17, 2020Assignee: University of South FloridaInventors: Sinan Onal, Susana Karina Lai-Yuen, Alfredo Weitzenfeld, Stuart Richard Hart

Patent number: 10517642Abstract: A laparoscopic device with obturator. The device facilitates extraction of specimens from a female subject's abdominal cavity through the subject's vagina by also facilitating the suturing of a mesh to the anterior and posterior walls of the subject's vagina. The device includes an elongate sheath that has a flat surface on the front, a curved shape on the back, and an inner port opening formed within the flat surface, where the port opening that enables introduction of instruments or removal of specimens from the peritoneal cavity. An internal obturator can be inserted into the sheath to reduce the size of the port opening into the peritoneal cavity, or can be used to close the inner port opening into the peritoneal cavity. The obturator and sheath can be utilized as firm surfaces against which a user can suture a sacrocolpopexy mesh to the anterior and posteriors vaginal walls.Type: GrantFiled: January 12, 2018Date of Patent: December 31, 2019Assignee: University of South FloridaInventors: Stuart Richard Hart, Mario Alves Simoes, Mark Antoine Zakaria

Patent number: 10150265Abstract: A method of manufacturing a synthetic tissue model using one or more semi-flexible polymers or resin with at least one embedded mesh material is provided herein. The model provides suitable simulation of animal tissue designed to mimic tissue stiffness through varying the polymerization to simulate tissue stiffness level. Multiple polymers or multiple layers of polymer possessing different polymerization levels can be used to simulate tissues with different layers, such as skin. A mesh incorporated in the model provides durability, and can simulate layers of tissue through selection of the mesh material. A skin model using silicone-like material with a nylon tulle mesh was used to simulate skin for surgical procedures. The nylon tulle mesh increased resistance to tearing over time, due to insertion of surgical tools, thereby increasing usable life of the model and enhancing training as the model simulated skin for longer periods of time.Type: GrantFiled: October 28, 2016Date of Patent: December 11, 2018Assignee: University of South FloridaInventors: Stuart Richard Hart, Mario Alves Simoes

Patent number: 10083629Abstract: A vaginal cuff surgical model and methods of manufacture and use thereof. The model includes a body (resembling a vaginal cuff) and appendages (resembling uterosacral ligaments) extending from the body. The model (body and appendages) is formed of silicone, rubber, a polymer, or other suitable material with one or more layers of mesh embedded within the polymeric material. The embedded mesh permits suture between the components of the model. The surgical model permits surgical practice of this important component of a total hysterectomy procedure via suturing across the model and to the appendages.Type: GrantFiled: June 28, 2016Date of Patent: September 25, 2018Assignee: University of South FloridaInventors: Mario Alves Simoes, Stuart Richard Hart, Omar Carambot, Mark Evans Armstrong

Patent number: 9789268Abstract: In laparoscopic surgery, small (5-12 mm diameter) incisions are made in an abdominal wall through which instruments dissect and remove specimens that may be several centimeters in diameter. Removal of a sample typically requires either enlarging these incisions or morcellating the sample to pass through sub-centimeter ports. A laparoscopic device permits extraction of the sample to be removed in a female using a vagina, which has sufficient elasticity to accommodate removal of large specimens. A posterior portion of the vagina communicates to an abdomen through a few tissue layers, and is distant from vital anatomic structures. Utilizing the vagina is optimal due to its ease of access to the abdomen and repair, minimal scarring and post-operative pain, and faster recovery following surgery. A deployable collection bag is housed in a sheath, which is deployed into the vagina or an abdominal cavity to extract a large (multiple-centimeter) specimen(s) through the vagina.Type: GrantFiled: June 5, 2014Date of Patent: October 17, 2017Assignee: University of South FloridaInventors: Stuart Richard Hart, Philip James Hipol, Mario Alves Simoes, Mark Antoine Zakaria

Patent number: 9629650Abstract: A laparoscopy tool includes a sheath and a control wire slideably disposed within a lumen of the sheath. The sheath has a diameter of less than 1.6 mm and is introduced through an abdominal incision. A handle axially displaces the control wire within the lumen and operates a conventional tip with wire-controlled opposing jaws that is introduced through the umbilicus and has a bore formed in its trailing end. A first set of blades in the bore engage grooves formed in the leading end of the control wire and a second set of blades engages the sheath to prevent sheath retraction. A cam displaces the second set of blades away from the sheath for sheath introduction and removal, and toward the sheath to prevent sheath retraction. The tip is removed through the umbilicus and the tool is removed through the abdominal incision when the surgery is completed.Type: GrantFiled: October 2, 2015Date of Patent: April 25, 2017Assignees: University of South Florida, The Charles Stark Draper Laboratory, Inc.Inventors: Stuart Richard Hart, Mario Alves Simoes, Philip James Hipol, Kevin Hufford
