A system to treat a patient comprises a user interface that allows a physician to view an image of tissue to be treated in order to develop a treatment plan to resect tissue with a predefined removal profile. The image may comprise a plurality of images, and the planned treatment is shown on the images. The treatment probe may comprise an anchor, and the image shown on the screen may have a reference image marker shown on the screen corresponding to the anchor. The planned tissue removal profile can be displayed and scaled to the image of the target tissue of an organ such as the prostate, and the physician can adjust the treatment profile based on the scaled images to provide a treatment profile in three dimensions. The images shown on the display may comprise segmented images of the patient with treatment plan overlaid on the images.

The present disclosure is directed to a medical device. Systems and methods are provided for utilizing a laser to break a kidney stones into smaller fragments and/or dust, and removing particles, stone fragments and/or stone dust from a patient. The medical device may include a delivery device including a tube, and an elongate member having a distal end, a proximal end, and a lumen extending between the proximal end and the distal end, wherein the elongate member is configured to move axially relative to the tube and apply suction through the distal end.

A surgical instrument for treating the stomach tissue of a patient is disclosed. The surgical instrument comprises a handle comprising a display, a shaft extending from the handle, and an end effector extending from said shaft. The surgical system comprises a tissue treatment system configured to treat the stomach tissue along a path, an imaging system configured to capture a tissue image of the stomach tissue, and a controller configured to determine an edge of the stomach tissue, generate an image representing at least a portion of the edge of the stomach tissue, and display the image along with at least a portion of the tissue image on the display.

A method for conducting intrabody surgery by means of a surgical device having a cutting arrangement actuated by a driveshaft and rotationally supported by the guide wire. A receiving cannel extends through the cutting arrangement and movably receives the guidewire. A plurality of sensors is provided within the cutting arrangement to emit signals capable of changing parameters depending on the composition of the occlusion, so as to allow the control unit to generate signals controlling operation of the cutting arrangement. The method includes the steps of detecting parameters within the intrabody area by the sensors to controlling operation of the cutting arrangement with the power and control unit.

A device for treating infection within a subject includes an ultrasound transducer for applying ultrasound to a treatment site of the subject. In some embodiments, the device transmits ultrasound in the range of greater than about 20 kHz to about 5 MHz to site of infection. For example, the device can transmit ultrasound from a location outside the body to a location inside the body, such as a sinus. The ultrasound may be suitable for removing biofilm or decreasing the viscosity of mucus. Ultrasound from the device can also have other therapeutic and diagnostic uses.

A suture-carrying apparatus includes a suture engaging ridge for placement and retention of surgical sutures, and a base for conveniently mounting the apparatus to a predetermined location, such as a body structure, which is reachable by robotic arms during a robot-assisted surgical operation. The base may be configured to allow stability of the apparatus for one-handed placement and retrieval of sutures from the ridges.

A distal aspiration catheter comprises a catheter body having a central lumen, at least one distal opening and a distal tip positioned distally to the at least one distal opening. An aspiration source is configured to attach to a proximal end/luer hub of the central lumen. When the aspiration source is activated, a clot/emboli lodged in a blood vessel is partially ingested into the at least one distal opening of the catheter body by the application of a static aspiration force. The aspiration source may activate a cyclic aspiration force with a forward pressure flow to induce clot fatigue into the partially ingested clot. The fatigued clot can be collected inside the distal tip of the catheter and be removed completely by a single pass of the distal aspiration catheter.

In some embodiments, a suction-based tool for positioning an intraocular implant includes a tool body defining an internal channel; a suction extension extending through the internal channel; and a suction attachment connected to an end of the suction extension. In additional embodiments, a suction-based tool for positioning an intraocular implant includes: a tool body including a tool tip; a joint at an end of the tool tip; and a suction attachment connected to the tool tip via the joint.

Methods and apparatus are provided to facilitate the minimally invasive removal of tissue biopsies and to facilitate the direct approach to anesthetizing the chest wall, in accordance with embodiments of the present invention. A pull-type cutting device 1 comprises two coaxially nested tubes, each extending from a proximal end 21 to a distal end 22. The first tube 61 defines a guide wire lumen 23 for slidingly receiving a guide wire. The second tube 63 extends over the first tube 60 and coupled thereto at the distal end 22 defining an expandable portion 13 adjacent the distal end 22. The second tube 63 defines an inflation lumen 25 extending from the shaft proximal end 21 to the expandable portion 13. The inflation lumen 25 communicates inflation fluid from the proximal end 21 to the expandable portion 13 so as to inflate and deploy the expandable portion 13. Disposed adjacent the shaft distal end 22 is a cutting head 10 comprising the expandable portion 13 having a cutting portion 11 distal from the shaft distal end 22.

A method using a guide to assist in insertion of a helicoidal member in a target biological tissue. The method includes abutting a substantially longitudinally extending portion of the guide against a target tissue exposed surface with the helicoidal member mounted thereto so that at least a portion of the guide is inserted in a helicoidal member passageway substantially parallel to a helicoidal member longitudinal axis of the helicoidal member; adhering the substantially longitudinally extending portion of the guide to the target tissue exposed surface with the helicoidal member longitudinal axis substantially parallel to the target tissue exposed surface; and advancing the helicoidal member in the target biological tissue in a substantially helicoidal movement with the guide remaining substantially fixed relative to the target biological tissue.
