Publication number: 20200222667Abstract: A guiding sheath assembly has a shaft that is operable to define more than one deflection curvature and defines a lumen to slidably receive a cardiovascular catheter. The guiding sheath assembly includes a proximal section, a distal section, and a stiffener member. The proximal section has a proximal shaft that defines a proximal lumen extending distally along a longitudinal axis to the distal section. The distal section has a distal shaft that defines a distal lumen that is configured to be biased (e.g., resiliently biased) laterally away from the longitudinal axis. The stiffener member is a rigid elongate member, such as an inner tubular member, that is configured to counteract the bias of the distal shaft. Longitudinal movement of the stiffener member relative to the distal section enables the operator to select and set a deflection curvature of the distal section.Type: ApplicationFiled: March 17, 2020Publication date: July 16, 2020Inventors: Raymond Y. Tang, Mark T. Stanley, Christopher T. Beeckler

Patent number: 9616185Abstract: A valve assembly and method are provided for selectively controlling a flow of pressurized fluid from a fluid source to trocar assemblies. The valve assembly includes a first coupling for a primary trocar assembly for directing pressurized fluid thereto, a second coupling for a secondary trocar assembly for directing pressurized fluid thereto, a third coupling for a source of pressurized fluid for directing pressurized fluid from the source to the first and second couplings; and at least one valve member to be operable in at least first and second operating positions, the first operating position directing pressurized fluid from the source to a coupled primary trocar assembly while preventing pressurized fluid from the source from flowing to at least a coupled secondary trocar assembly, and the second operating position directing pressurized fluid from the source to the coupled primary trocar assembly and to at least the coupled secondary trocar assembly.Type: GrantFiled: March 27, 2015Date of Patent: April 11, 2017Assignee: SURGIQUEST, INC.Inventors: Dominick Mastri, Raymond Y. Tang, Ralph Stearns, Kenneth Blier

Patent number: 9375539Abstract: The subject multimodal surgical gas delivery system configured to couple to one or more surgical devices providing access into a patient body cavity includes a computer-controlled control unit configured and adapted to provide at least one of the following modes of operation. A first mode of operation for providing a pressurized insufflation fluid from an insufflation gas source into a surgical device for providing and maintaining sealable access to the body cavity in a surgical device. A second mode of operation for performing smoke evacuation in a filter element from insufflation fluid caused to recycle through the multimodal system from the body cavity via a surgical device. A third mode of operation for providing insufflation fluid from the insufflation gas source into the body cavity for creating and maintaining insufflation of the body cavity.Type: GrantFiled: September 20, 2011Date of Patent: June 28, 2016Assignee: SurgiQuest, Inc.Inventors: Ralph Stearns, Dennis Feldman, Raymond Y.
