Publication number: 20240122453Abstract: In vivo visualization systems are described which facilitate tissue treatment by a user in utilizing real time visualized tissue images with generated three-dimensional models of the tissue region of interest, such as the left atrial chamber of a subject's heart. Directional indicators on the visualized tissue as well as the imaging systems may be utilized while other variations may utilize image rotation or manipulation of visualized tissue regions to facilitate catheter control. Moreover, visualized tissue regions may be combined with imaged tissue regions as well as navigational information to further facilitate tissue treatments.Type: ApplicationFiled: December 21, 2023Publication date: April 18, 2024Inventors: Vahid Saadat, Antony Jonathan Fields, Zachary J.

Patent number: 11559188Abstract: A system for visualizing a tissue region of interest comprises a deployment catheter defining a lumen and a hood coupled to and extending distally from the deployment catheter. The hood has a low-profile configuration within a delivery sheath and a deployed configuration when extended distally of the delivery sheath. The hood in the deployed configuration defines an open area in fluid communication with the lumen. A distal portion of the deployment catheter extends into the open area. An imaging element is coupled to an imager support member. When in the deployed configuration, the imaging element is configured to extend distally of the distal portion while the imager support member extends within the deployment catheter. The imaging element comprises a tapered surface and the deployment catheter comprises a complementary tapered surface. Retraction of the imaging element causes the imaging element to shift radially outward from a longitudinal axis.Type: GrantFiled: June 16, 2020Date of Patent: January 24, 2023Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Vahid Saadat, Ruey-Feng Peh, Chris A.

Patent number: 10441136Abstract: A method of treatment comprises intravascularly securing an anchor extending from an anchor member at least partially within a vessel lumen such that blood flows unobstructed through or past the anchor. While the anchor is secured, a distance of the anchor member, between the anchor and a barrier or membrane projecting distally from a deployment catheter, is adjusted such that an open area defined by the barrier or membrane is placed against or adjacent to a portion of a patient tissue. Adjusting the distance of the anchor member comprises moving the deployment catheter distally with respect to the anchor member. The method also comprises displacing blood with a transparent fluid from the open area, and while the anchor is secured, articulating the barrier or membrane circumferentially around the anchor. The method also includes treating the tissue while visualizing through the transparent fluid.Type: GrantFiled: February 16, 2016Date of Patent: October 15, 2019Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Vahid Saadat, Ruey-Feng Peh, Chris A.

Patent number: 10390685Abstract: A system comprises a deployment catheter defining at least one lumen and a hood projecting distally from the deployment catheter and defining an open area. The open area is in direct fluid communication with the at least one lumen. The system also comprises an elongate channel directly coupled to the hood such that the elongate channel terminates distally into the open area. The elongate channel extends proximally from an outer surface of the hood and is bounded proximally at a proximal pocket surface. The system also comprises an imaging element. The imaging element is sized to pass into the elongated channel at a distal end of the elongate channel. Proximal movement within the elongated channel is restricted by the proximal pocket surface. The system also comprises a control member extending within the elongate channel and through the proximal pocket surface for moving the imaging element through the elongate channel.Type: GrantFiled: December 4, 2015Date of Patent: August 27, 2019Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Vahid Saadat, Chris A.

Patent number: 10335131Abstract: A method of inhibiting tissue migration comprises positioning an open area of a hood against or adjacent to a tissue region. The method also comprises displacing an opaque fluid with a transparent fluid from the open area. The method includes engaging a portion of the tissue region within the open area via an end effector advanced through the open area and which grasps onto the portion. The end effector includes a tapered section, tapered along its entire length, through which a lumen extends. The tapered section includes threads extending from a surface of the tapered section in a direction orthogonal to the longitudinal axis. The tissue region is pierced while displacing the opaque fluid with the transparent fluid through the distal opening of the hood and while maintaining engagement of the portion of the tissue region such that distal movement of the tissue is inhibited.Type: GrantFiled: October 23, 2007Date of Patent: July 2, 2019Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Vahid Saadat, Ruey-Feng Peh, Edmund A.

Patent number: 10064540Abstract: Visualization apparatus and methods for transseptal access are described herein where intravascular access across a septal wall is facilitated via devices which provide for direct visual viewing of tissue area. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to the tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid can be pumped into the imaging hood until the fluid displaces any blood leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. Any number of therapeutic tools or a guidewire can be passed through the catheter and into the imaging hood for crossing the septal wall and passing the guidewire or instruments therethrough.Type: GrantFiled: June 14, 2007Date of Patent: September 4, 2018Assignee: Intuitive Surgical Operations, Inc.Inventors: Vahid Saadat, Amir Abolfathi, Chris A.
