Publication number: 20230225606Abstract: A cystoscope and system are disclosed in which a repository of the cystoscope is configured to receive a cartridge tool and provide access to a working channel of an elongated shaft of the cystoscope. The handle of the cystoscope has a first control for actuating a movable element of the repository. The movable element is configured to engage a cartridge tool received within the repository and thereby implement a functionality of the cartridge tool when the first control is actuated.Type: ApplicationFiled: January 18, 2023Publication date: July 20, 2023Applicant: Prodeon Medical, Inc.Inventors: Al Burdulis, Craig Purdy, Gary Daniel Zaretzka

Publication number: 20220008093Abstract: An self-actuating grasping device and corresponding method of using the grasping device for retrieving a foreign object from a location in a patient's body. The grasping device has a handle with a self-actuating mechanism, an actuator on the handle coupled to an actuator wire, an elongated shaft member extending distally from the handle with the actuation wire coaxially disposed therein and opposing jaws at a distal end of the elongated shaft member that are coupled to the actuation wire and pivot between open and closed configurations. The self-actuating mechanism has a bias that imparts a closing force to the opposing jaws through the actuation wire. Actuation of the actuator is configured to impart an opening force to the opposing jaws through the actuation wire.Type: ApplicationFiled: July 6, 2021Publication date: January 13, 2022Applicant: Prodeon Medical CorporationInventors: Jimmy Jen, Kenneth Chih-Ping Chang, Craig Purdy, Gary Daniel Zaretzka, Po-Hua Lee

Publication number: 20210022594Abstract: Devices and systems are disclosed for managing and/or treating body tissues obstructing a hollow body lumen, including the prostatic lobe tissues obstructing the urethra, for example conditions including benign prostatic hyperplasia (BPH), bladder outlet obstruction (BOO), benign prostatic obstruction (BPO) and associated lower urinary tract symptoms (LUTS). An implant is maintained in a constrained configuration within a distal portion of an elongated sheath so that is may be deployed by driving the implant with a pusher coaxially disposed within the sheath. An implant engaging element helps maintain control of the implant during deployment.Type: ApplicationFiled: October 9, 2020Publication date: January 28, 2021Inventors: Jimmy Jen, Gary Daniel Zaretzka, Kenneth Chih-Ping Chang, Kondapavulur T.

Patent number: 10342563Abstract: An anti-clogging device for a vacuum-assisted tissue removal system is provided. The device includes a tissue-separation chamber in a close proximity to (i) a cutting head operated by a physician and (ii) the physician for a filling and emptying by the physician during a tissue removal procedure, the cutting head and the tissue separation chamber in an operable communications with the suction assembly. The tissue separation chamber has an entry port in an operable communication with the cutting head for the entry of an excised tissue into the chamber, the excised tissue having a solid component and a liquid component; a baffle to separate the liquid component from the solid component; and, an exit port for the exit of liquid component out of the chamber. The tissue can include any tissue accessible through a small surgical opening, such as a nucleus pulposus tissue removed during a discectomy procedure.Type: GrantFiled: July 15, 2014Date of Patent: July 9, 2019Assignee: DePuy Synthes Products, Inc.Inventors: John To, Fred Osorio, Gary Daniel Zaretzka
