Digital image analysis for robotic installation of surgical implants

Computer-implemented digital image analysis methods, apparatuses, and systems for robotic installation of surgical implants are disclosed. A disclosed apparatus plans a route within an anatomy of a patient from an incision site to a surgical implant site for robotic installation of a surgical implant. The apparatus uses digital imaging data to identify less-invasive installation paths and determine the dimensions of the surgical implant components being used. The apparatus segments the surgical implant into surgical implant subcomponents and modifies the surgical implant subcomponents, such that they can be inserted using the identified less-invasive installation paths.

Vessel sealer with heating and cooling capabilities

Certain aspects relate to systems, devices and techniques for vessel sealing and cutting. In particular, an instrument is provided that is capable of performing multiple functions, including sealing and cutting. The instrument can be robotically controlled, and can include a shaft, a multi-DOF wrist, and an end effector. The end effector is capable of generating and delivering heat via different energy modalities to perform the various functions at different temperatures.

Stapler apparatus and methods for use
11589864 · 2023-02-28 · ·

Apparatus and methods are provided for performing a medical procedure, such as a laparoscopic appendectomy using a stapler apparatus including a reusable handle portion including a shaft include proximal and distal ends, a disposable end effector attached to the distal end of the shaft of the reusable handle carrying one or more staples. For example, the end effector may include first and second jaws movable relative to one another between open and closed positions, the first jaw carrying a cartridge which includes the one or more staples. A Doppler sensor, a cutting element, and, optionally, a thermal element are also provided on the end effector. The end effector is introduced into a patient's body, tissue is positioned/locked between the jaws, and a plurality of staples are deployed into the tissue. The Doppler sensor is used to confirm that blood flow has discontinued in the stapled tissue, and the cutting element is actuated to sever the stapled tissue.

SYSTEMS AND METHODS FOR TREATING TISSUE WITH RADIOFREQUENCY ENERGY

A device for applying radiofrequency energy for sphincter treatment comprising a flexible outer tube, an expandable basket having a plurality of arms movable from a collapsed position to an expanded position, and a plurality of electrodes movable with respect to the arms from a retracted position to an extended position. An advancer is slidably disposed within the outer tube to move the plurality of electrodes to the extended position. An actuator moves the advancer from a first position to a second position to advance the plurality of electrodes. An aspiration tube extends within the outer tube. An assembly includes an aspiration disabler having a first position to enable aspiration from a distal portion of the aspiration tube to a proximal portion and a second position to disable aspiration.

SYSTEMS AND METHODS TO BLOCK OR INHIBIT GAS PROGRESSION DURING SPRAY CRYOTHERAPY
20230000536 · 2023-01-05 ·

The present disclosure relates generally to the field of cryoablation. In particular, the present disclosure relates to cryoablation systems (e.g., cryospray systems, cryogenic ablation, cryosurgery systems etc.) that prevent or significantly inhibit cryospray gases from accumulating and progression distally beyond a specific region within a body lumen.

APPARATUSES FOR STENT DELIVERY AND POSITIONING FOR TRANSLUMINAL APPLICATION

Methods, apparatuses, and systems are described for stent delivery and positioning for transluminal application. The system may include a stent that is disposed coaxially onto an inner tubular member. In some cases, the system may include an outer sheath disposed coaxially along at least a portion of the inner tubular member. The system may include a distal cutting element coupled with a distal end of the inner tubular member and an anchoring component disposed at a distal portion of the inner tubular member. The anchoring component may be configured to retain a distal portion of the stent in place along the inner tubular member as the outer sheath is retracted proximally to deploy the stent, wherein upon retraction of the outer sheath, the stent releases from the anchoring component and expands into a deployed configuration within the body lumen.

Multifunction medical device and related methods of use

An embodiment of the invention may include a medical device. The medical device may include a flexible tube, an elongate member configured to cut tissue and extend from the flexible tube, and a cauterizing member configured to cauterize tissue and to move relative to the elongate member and the flexible tube. The cauterizing member may substantially surround at least a portion of the elongate member.

TISSUE TREATMENT SYSTEMS, DEVICES, AND METHODS

Provided herein are systems for treating tissue of a patient. The system comprises an energy delivery console and at least one energy delivery device. The energy delivery console can provide a first dose of energy and a second dose of energy. An energy delivery device comprises a first delivery element configured to deliver the first dose of energy to target tissue, and a second delivery element configured to deliver the second dose of energy to the target tissue. The first dose of energy can comprise a delivery of energy that reversibly alters the target tissue, and the second dose of energy can comprise a delivery of energy that irreversibly alters the target tissue. The first dose of energy can be delivered to enhance a therapy provided by the second dose of energy.

Systems and methods for treating tissue with radiofrequency energy

A system for controlling operation of a radiofrequency treatment device to apply radiofrequency energy to tissue to heat tissue to create lesions without ablating the tissue. The system includes a first treatment device having at least one electrode for applying radiofrequency energy to tissue, a controller including a connector to which a first treatment device is coupled for use, and a generator for applying radiofrequency energy to the electrodes. The controller controls application of energy so that the tissue is thermally treated to create lesions but preventing thermal treatment beyond a threshold which would ablate the tissue.
