  • Publication number: 20220387039
    Abstract: Disclosed embodiments include apparatuses, systems, and methods for driving a needle to facilitate suturing, such as may be performed in a surgical anastomosis procedure. In an illustrative embodiment, an apparatus includes a frame. First and second rollers are rotatably mounted parallel with each other in the frame and are configured to engage therebetween a shaft of a needle formed in a helical shape. The first and second rollers are configured to counter-rotate. The needle is revolvable eccentrically around the first roller responsive to counter-rotation of the first and second rollers. A drive mechanism is secured to the frame and is configured to move the frame.

  • Publication number: 20220249076
    Abstract: A device having a sheath, a medical device, a stylet, a handle and a plunger device. The handle includes portions connected proximal ends of the sheath, the medical device and the stylet and a chamber portion connected to the actuator. The chamber portion includes a volume of space configured to volumetrically connect to at a lumen of the medical device, the sheath or the stylet and a plunger device configured to be slidably received within the chamber portion. The plunger device is able to pneumatically isolate a proximal portion of the volume of space from a distal portion of the volume of space. Proximal movement of the stylet and the plunger device cause a suction effect (i.e., reduced pressure) at the distal end of the sheath, the medical device and/or the stylet.

  • Patent number: 11406365
    Abstract: A device having a sheath, a medical device, a stylet, a handle having a chamber portion and a plunger device. The handle connects to proximal ends of the sheath, the medical device, and the stylet. The chamber portion includes a volume of space configured to volumetrically connect to at a lumen of the medical device, the sheath or the stylet. The plunger device slides and moves within the chamber portion. The plunger device is able to pneumatically or hydraulically isolate a proximal portion of the volume of space from a distal portion of the volume of space. Proximal movement of the stylet and the plunger device cause a suction effect (i.e., negative or reduced pressure) at the distal end of the sheath and/or the medical device.

  • Publication number: 20190099216
    Abstract: An electrosurgical instrument includes a needle configured as a first electrode and a coil extending through the needle and configured as a second electrode. The coil movable relative to the needle, and as the needle and the coil are inserted into tissue and energized with an electrical energy source, the needle and the coil apply current to the tissue to coagulate the tissue.
