Patent number: 10555666Abstract: A cannula system and method for accessing a blood mass in the brain. The system comprises a cannula with a camera mounted on the proximal end of the cannula with a view into the cannula lumen and the surgical field below the lumen. A prism, reflector or other suitable optical element is oriented between the camera and the lumen of the cannula to afford the camera a view into the cannula while minimizing obstruction of the lumen. The system may also include an obturator with a small diameter shaft and a large diameter tip which is optically transmissive, so that a surgeon inserting or manipulating the assembly can easily see that the obturator tip is near brain tissue (which is white) or blood (which is red).Type: GrantFiled: January 4, 2019Date of Patent: February 11, 2020Assignee: Rebound Therapeutics CorporationInventors: Peter G. Davis, Ross Tsukashima, Jeffrey J. Valko, Michael R. Henson, Todd D. McIntyre

Patent number: 10543016Abstract: An introducer system for use with a navigation probe. The introducer system has an introducer and a probe retainer configured to selectively connect to the introducer. The probe retainer includes a receiver configured to receive a navigation probe shaft and limit movement of the navigation probe shaft in the lateral direction. A first clamp and a second clamp are connected to the receiver with the receiver located between the first clamp and the second clamp. Each of the first clamp and the second clamp is selectively engageable with respective portions of the introducer sidewall to hold the receiver at a fixed location relative to the introducer. The receiver, the first clamp, and the second clamp are configured to provide a visual path through the probe retainer and into the introducer passage.Type: GrantFiled: November 7, 2017Date of Patent: January 28, 2020Assignee: Vycor Medical, Inc.Inventors: David Cantor, Robert Schaefer

Patent number: 10542869Abstract: Provided are an endoscopic surgical device and a guide device that can satisfy the function of interlocking two medical instruments with each other. An overtube, which is punctured into a body wall and guides an endoscope and a treatment tool into a body cavity, includes an interlocking member that interlocks the forward and backward movements of the endoscope and the treatment tool with each other. The interlocking member is constituted of a first sleeve coupled to the endoscope, a second sleeve coupled to the treatment tool, and a corded flexible coupling member that couples the first sleeve and the second sleeve together. Accordingly, when the coupling member is in a relaxed state, the endoscope and the treatment tool independently move forward and backward, and when the coupling member is in a tensioned state, the endoscope and the treatment tool move forward and backward in an interlocking manner.Type: GrantFiled: January 30, 2018Date of Patent: January 28, 2020Assignee: FUJIFILM CorporationInventors: Kimiaki Nakada, Takumi Dejima, Masayuki Iwasaka
