Abstract: A probe configured to deliver energy to a first tissue is placed in the first tissue, and an imaging device is configured to image a second tissue with the probe placed in the first tissue. Image data from the second tissue is processed to evaluate the effect of the energy source on the second tissue. In some embodiments, the image data from the second tissue is used to adjust the energy to the first tissue, for example by increasing or decreasing the energy to the second tissue. In some embodiments, image data from the first tissue or the second tissue or force sensor data from the probe is used to evaluate placement of the probe in the first tissue, and the placement of the probe in the first tissue adjusted to decrease tissue alterations of the second tissue related to probe placement in the first tissue.

Abstract: A user interface presents a 3D view of the tissue and treatment plan. The 3D view comprises a plurality of transverse images arranged along a one or more longitudinal images. The user adjusts the treatment profile with input to the user interface, and an updated treatment profile is shown on the other views. The user to one or more of zoom, pan, or rotate the 3D view with the treatment profile overlaid on the 3D view, and the treatment profile moves with the 3D view to maintain registration with the 3D view. In some embodiments, a 3D treatment plan is generated in accordance with a plurality of angles between a treatment probe and the one or more tissue structures. An AI algorithm can be used to identify tissue structures and plan the treatment angles and energy delivery in accordance with the tissue structures, which can provide a more customized treatment.

Abstract: A system for determining a position or an orientation of a probe across a drape may include a fiducial assembly that may be coupled to the probe though a drape. The fiducial assembly may include a base, a coupling attached to the base which may be configured to couple the fiducial assembly to the probe across the drape, and one or more fiducials attached to the base. Coupling the fiducials to the probe across the drape can allow sterile fiducials to be coupled to a non-sterile probe to determine the position and orientation of the probe based on images from the of the fiducials on a sterile side of the drape. In some embodiments, the fiducial is aligned with respect to an elongate axis of the probe with a predetermined offset and orientation with respect to the elongate axis of the probe.

Abstract: Disclosed herein are improved methods and apparatuses for providing hemostasis within a cavity defined by an internal surface of a bleeding tissue space. A catheter comprising a proximal end and a distal end may be advanced into the cavity through a proximal opening of the tissue space into the cavity. A distal balloon coupled to the catheter may be expanded, and the catheter tensioned to apply pressure to the internal surface of the tissue space to inhibit bleeding of the tissue space.

Abstract: Systems, methods, and apparatuses detect tissue strain associated with tissue resistance and shearing and provide feedback such as real time feedback during insertion of a probe, which can decrease potential tissue damage associated with insertion of a probe. In some embodiments, a method may include generating one or more digital images of a tissue, determining a strain imparted on the tissue based on the one or more digital images, and providing feedback based on the detected strain. The feedback may be one or more of audible, visual, or haptic feedback. The feedback may be provided when the determined strain is above a threshold. The strain may be determined through the use of an artificial intelligence or machine learning classifier.

Abstract: A probe for insertion into a patient comprises an elongate body. The elongate body comprises a distal portion and a proximal portion, in which the distal portion is shaped for insertion into the patient, and the proximal portion is coupled to the distal portion to advance the distal portion with advancement of the proximal portion. One or more sensors are supported with the elongate probe body and coupled to the distal portion of the probe to detect tissue resistance of the distal portion of the probe during insertion of the probe. An output is operatively coupled to the one or more sensors to provide feedback to a user in response to the tissue resistance. This output allows the user to respond and decrease pressure to the tissue. In some embodiments, a sheath comprising the one or more sensors is configured for placement over the probe prior to insertion.

Abstract: An energy source is offset from an elongate probe axis with an extension. The amount of offset of the energy source can be controlled by varying an amount of offset of the extension. The energy source rotated and translated at the offset distance to resect tissue. In some embodiments, the probe is configured to receive a second treatment probe comprising a second energy source, in which the second energy source is rotated and translated relative to the first treatment probe, which can improve positional accuracy and stability. The energy source and the extension can be coupled to a linkage to offset the energy source, and to translate and rotate the energy source with varying amounts of offset. The linkage can be coupled to a processor and one or more of the energy source moved in accordance with a treatment profile.

Abstract: A system for extracting lens material from an eye including an instrument having a first aspiration pump driven by a drive mechanism having a motor, and an elongate member sized and configured to extend through an anterior chamber to a capsular bag of the eye. The elongate member configured to be oscillated by the drive mechanism includes an inner lumen fluidly coupled to the first aspiration pump and defining at least a portion of an aspiration waste line, and an open distal end having a distal cutting tip. The system can further include a fluid system remote from the surgical instrument including a second aspiration pump and a fluid line configured to deliver background aspiration from the second aspiration pump to the inner lumen of the elongate member to aspirate the lens material from the eye towards the inner lumen. Related devices, systems, and methods are also provided.

Abstract: Disclosed herein are improved methods and apparatuses for providing hemostasis within a cavity defined by an internal surface of a bleeding tissue space. A catheter comprising a proximal end and a distal end may be advanced into the cavity through a proximal opening of the tissue space into the cavity. A distal balloon coupled to the catheter may be positioned adjacent a distal opening of the tissue space, and expanded to seal the distal opening. A hemostatic agent may be applied from the catheter to the internal surface of the tissue space to inhibit bleeding of the tissue space. The hemostatic agent may be applied without occluding the proximal opening, the distal opening, and a path extending therebetween with the hemostatic agent.

Abstract: A surgical treatment apparatus comprises an elongate support, an elongate tube, and a movable endoscope having a stiff distal portion, in which the stiff distal portion of the endoscope is configured to move one or more components of the apparatus when the support remains substantially fixed. The support may comprise a plurality of spaced apart aspiration openings near the distal end in order to facilitate alignment with the treatment site. In many embodiments, an image guided treatment apparatus is configured for use with an imaging device. In many embodiments, a target resection profile is provided. The target resection profile and one or more tissue structures are displayed on an image, and the target resection profile displayed on the image is adjusted with user input.
