Patent number: 12135174Abstract: A heat exchange system for a surgical instrument includes a valve, a load, and a load conduit extending between the valve and the load. The load conduit delivers fluid from the valve to the load. The heat exchange system also includes an exhaust conduit that directs the fluid away from the valve. A portion of the load conduit is positioned so as to thermally transfer heat to a portion of the exhaust conduit.Type: GrantFiled: February 12, 2021Date of Patent: November 5, 2024Assignee: Medical Instrument Development Laboratories, Inc.Inventors: Jeffrey A. Walker, Erik W. Peterson, David Chen

Publication number: 20230305526Abstract: Surface editing is performed in typical computer-aided design (CAD) software products by using special tools to edit special surfaces, such as b-splines or subdivision surfaces. It is recognized herein that current approaches to editing surfaces are not generally applicable. For example, common CAD and surface modeling software products are tailored to a specific surface type or vendor specific format, or otherwise are not generally applicable to given analytical and non-analytical surfaces. In various embodiments described herein, subdivision surfaces can be generated to represent any surface. Further, surfaces can be manipulated using a control cage associated with the subdivision surface.Type: ApplicationFiled: August 20, 2020Publication date: September 28, 2023Applicant: Siemens Industry Software IncInventors: Vadiraj Mysore, Jeffrey A.

Patent number: 10918525Abstract: A tympanostomy tube delivery device comprises a shaft assembly, a pressure equalization tube, and a sensor. The shaft assembly comprises a cannula and a pusher operable to translate relative to the cannula. The pressure equalization tube is positioned within the shaft assembly. The pusher is operable to drive the pressure equalization tube out of the shaft assembly. The sensor is operable to detect a physical parameter associated with engagement between the distal end of the shaft assembly and a tympanic membrane. A controller may activate a feedback device to inform an operator that the distal end of the shaft assembly has achieved suitable apposition with the tympanic membrane, based on information from the sensor.Type: GrantFiled: February 28, 2019Date of Patent: February 16, 2021Assignee: TUSKER MEDICAL, INC.Inventors: Bernard H.
