A system and method, including an ultrasound imaging transducer, an ultrasound therapy transducer, a robotic arm configured to orient the ultrasound imaging transducer and the ultrasound therapy transducer about a patient, a display connected to imaging transducer, and a memory, storing instructions that when executed by a processor receive ultrasound images from the imaging transducer, present ultrasound images, receive an input to alter a shape of a contour line, present the contour line, receive an input of a size of a margin around the treatment area, present the margin, determine end points at locations where X, Y, and Z axes bisect the contour line in an XZ plane and a YZ plane, drive the ultrasound therapy transducer to a location where a focal point of the ultrasound therapy transducer is at the end point, and determining whether a resistance to movement exceeds a threshold.

Histotripsy systems and associated methods including user interfaces and workflows for treatment planning and therapy

Treatment head for an ultrasound therapy device

A handle for longitudinal movement of a first tubular member over a second tubular member includes a handle body, a nose cone, a locking mechanism, and a retraction control. The nose cone has a sleeve and an outer wall that define a control channel therebetween. The nose cone is moveable over the handle body between extended and retracted positions. The locking mechanism has locked and unlocked positions for selectively fixing the nose cone in the extended and retracted positions. A finger of the retraction control is positioned within the control channel of the nose cone. The retraction control has first and second positions relative to the nose cone for transitioning the locking mechanism between the locked and unlocked position and for moving the nose cone between the extended and retracted positions.

Microwave ablation catheter, handle, and system

Methods, systems, and devices for accessing tissue outside a bronchus and marking the location of a biopsy are provided. The method includes loading a navigation plan into a navigation system with the navigation plan including a CT volume generated from a plurality of CT images, inserting an extended working channel (EWC) including a location sensor into a patient's airways, registering a sensed location of the EWC with the CT volume of the navigation plan, and selecting a target in the navigation plan located outside the periphery of a patient's airways. The method further includes navigating the EWC and location sensor proximate the target, inserting a piercing catheter into the EWC, piercing through an airway wall to reach the target, storing a position of the location sensor in the navigation system as a biopsy location, and performing a biopsy at the stored biopsy location.

Navigable endobronchial tool to access tissue outside a bronchus

A catheter includes first and second handles, first and second tubular members, and first and second electrodes. The first tubular member defines a channel therethrough and is coupled to and distally extends from the first handle. The second tubular member is coupled to and distally extends from the second handle. The second tubular member is slidably disposed within the channel of the first tubular member and defines a lumen therethrough. The first and second electrodes are configured to generate an electric field therebetween. The second handle is translatable relative to the first handle between a retracted position in which the second electrode is adjacent the first electrode and an extended position in which the second electrode is spaced apart from the first electrode.

Electroporation catheter

A bronchial piercing catheter assembly used to navigate to target tissue in a patient under EMN guidance includes a handle, a shaft, and a catheter tip. The shaft extends from the handle and includes a proximal end and a distal end. The catheter tip is located on the distal end of the shaft and is designed to penetrate tissue. The catheter tip further includes a base member defined along a central longitudinal axis of the bronchial piercing catheter and a trailing tip member adjacent to the base member. The trailing tip member tapers relative to the base member and a leading tip member adjacent to the trailing tip member. The leading tip member further tapers to a distal end.

A support system including a rail, a lower support, and an instrument support. The lower support is configured to receive a portion of a bronchoscope and to selectively fix the bronchoscope relative to the rail. The instrument support is slidably disposed on the rail and is selectively lockable to the rail. The instrument support is configured to releasably couple to a surgical instrument inserted through the bronchoscope to fix the position of a portion of the surgical instrument relative to the bronchoscope.
