  • Publication number: 20240315677
    Abstract: A biopsy forceps device includes a control member; a yoke coupled to the member; jaws coupled to the yoke; and a capsule. In an open configuration, the jaws are separated to receive target tissue. In a closed configuration, cutting edges of the jaws are moved toward one another to cut tissue. The capsule slidably receives the yoke and a portion of the jaws. The jaws are constrained to the closed configuration when withdrawn proximally to a first position within the capsule. When the jaws are moved to a second position, portions of the jaws are freed from the constraint capsule and spread apart. When the yoke and the jaws are moved distally and the jaws move to the open configuration, a tissue contacting structure of the yoke extends distally to engage tissue between the jaws to anchor the engaged tissue again lateral movement as the jaws contact the tissue.

  • Patent number: 11957350
    Abstract: A device includes an elongated hollow member having an open distal end for receiving tissue therein and at least one exterior groove for loading at least one ligation band thereon. The device also includes a band deployment sleeve slidable over the exterior of the hollow member and configured to move from a radially expanded position to a radially contracted position in which, when the band deployment sleeve slides longitudinally over the hollow member, the distal portion engages the at least one ligation band. A closing sleeve slidable over the exterior of the band deployment sleeve is configured to constrain the distal portion from the radially expanded position into the radially contracted position. Retracting the closing sleeve proximally over the distal portion of the band deployment sleeve releases the distal portion from the radially contracted position into the radially expanded position.

  • Publication number: 20230329732
    Abstract: A device includes a catheter extending longitudinally from a proximal end to a distal end and including a lumen and a grasper. The grasper includes jaws connected such that the jaws are movable between an open configuration and a closed configuration. Also, the device includes a control member connected to the grasper so that a longitudinal movement of the member relative to the catheter moves the grasper between the configurations and a proximal interface including a piston connected to the proximal end so that, when the grasper is moved toward the closed configuration, the piston applies a negative pressure through the catheter to draw a separated portion of thrombus proximally therethrough.

  • Patent number: 11589851
    Abstract: A biopsy forceps device includes a tension member and an end effector including first and second jaws movable between an open configuration, in which the jaws are separated from one another to receive target tissue therebetween, and a closed configuration, in which cutting edges of the jaws are moved toward one another to cut a portion of the target tissue. The jaws define a tissue receiving space therebetween to house the cut tissue. The jaws are pivotable relative to one another, each of the jaws including a serrated cutting edge extending therealong, the end effector further including a tension member attachment including a proximal end coupled to the tension member. The attachment is movably coupled to the jaws so that distal movement of the attachment moves the jaws to the open configuration while proximal movement thereof moves the jaws to the closed configuration.

  • Patent number: 11583292
    Abstract: A device includes an anoscope including an elongated hollow member with a longitudinal slot configured to receive tissue in an interior of the hollow member. The device also includes a clip applicator. The clip applicator includes a body slidably received in the slot and jaws at a distal end of the body configured to hold a ligation clip. The clip applicator further includes a plunger slidably coupled to the body configured to actuate the jaws. When the clip applicator is inserted into the slot and the plunger is moved relative to the body, the jaws close and deform the ligation clip from an open position into a closed position around tissue received in the slot.
