  • Patent number: 10349970
    Abstract: A medical/surgical device for performing tissue resection can include an endoscope with proximal and distal ends, defining working channels, and a snare assembly located in one of the working channels. The working channel may include a bend near the distal end and towards the outward radial wall of the endoscope. The snare assembly may include a snare loop and an actuation element imparted with the pre-formed angular bends and an actuation control handle. The bends of the actuation element and the working channel may be the same. The rotational manipulation of the actuation element may synchronize the pre-formed bend of the actuation element with the bend of the working channel to concentrically (or otherwise) align the deployed snare loop with the endoscope or endoscope attachments.

    Abstract: A system and method for facilitating the removal of a tissue specimen from a patient is disclosed. The system includes a bag or pouch, a tissue cutter device, a support and a stabilizer. The tissue cutter device includes a passer, a wire, and a handle. The support is an elongated member. The passer is an elongated member configured to be coupled to the support and introduced as a temporary unit into the mouth of the bag or pouch in the patient's body holding the tissue specimen. The wire is attached to the passer. The temporary unit is configured to pass around the tissue specimen and out of the opening in the bag or pouch to carry the wire through that path so that a distal portion of the wire and a proximal portion of the wire are outside the patient's body. Those portions of the wire can be pulled to cut into the tissue specimen. The stabilizer holds the tissue specimen as the wire cuts into it.

  • Publication number: 20140288486
    Abstract: In laparoscopic surgery, small (5-12 mm diameter) incisions are made in the abdominal wall through which instruments dissect and remove specimens that may be several centimeters in diameter. Removal of the sample typically requires either enlarging these incisions or morcellating the sample to pass through the sub-centimeter ports. The laparoscopic device permits extraction of the sample to be removed in a female using the vagina, which has sufficient elasticity to accommodate removal of large specimens. The posterior portion of the vagina communicates to the abdomen through a few tissue layers, and is distant from vital anatomic structures. Utilizing the vagina is optimal due to its ease of access to the abdomen and repair, minimal scarring and post-operative pain, and faster recovery following surgery. A deployable collection bag is housed in a sheath, which is deployed into the vagina or abdominal cavity to extract a large (multiple-centimeter) specimen(s) through the vagina.

  • Publication number: 20140276907
    Abstract: Disclosed is an infinitely adjustable depth stop for a laparoscopic instrument having a shaft, the depth stop including a first component having a first annular space adapted to allow the shaft to be fitted therethrough. The first annular space has a reducible diameter and an interference surface against which the shaft may be fitted. Upon reduction of the reducible diameter, the interference surface frictionally engages the shaft to arrest relative movement of the depth stop along the shaft. The frictional engagement may be along a curve, a spiral curve, or an area. Means are also provided to reopen the reducible diameter to release the depth stop.

  • Publication number: 20140249391
    Abstract: Methods for distinguishing between two interspersed biological tissues, for procedures such as surgical resection, include exposing the tissues to at least two components, a first of which components produces or is capable of producing a detectable signal, and the other of which components either blocks the produced signal of the first component or activates the first component to produce the detectable signal. One of the components is selectively taken up by one of the tissues at a concentration which is greater than the concentration by which it is taken up by the other tissue to provide a distinguishable difference in the detectable signal originating from the two tissues.

  • Patent number: 8771288
    Abstract: A medical instrument converts linear movement of a shaft at a proximal end of the instrument to a rotational movement of an end effector of the instrument. According to one embodiment, the medical instrument includes an end effector formed of a snare loop connected to a shaft that is located within a sleeve. Once the sleeve is located near a desired location within a patient, the snare loop may be rotationally positioned with linear movement of the shaft by the operator. The shaft is formed with a threaded portion that matches threads formed in a torque transmitter element fixed within the sleeve. Linear movement of the shaft through the torque transmitter element causes the shaft to rotate. The medical instrument may also include a pivot connector for reducing torque build-up of the shaft and/or a clutch assembly for restricting controlled rotation of the snare loop to only one direction.
