  • Patent number: 11849924
    Abstract: A tissue resecting instrument includes a drive assembly coupled to an inner cutting shaft and configured to drive translation and/or rotation of the inner cutting shaft, a trigger coupled to the drive assembly and configured for manual actuation to drive the drive assembly, a vacuum generator configured to generate vacuum to suction cut tissue through the inner cutting shaft and into the vacuum generator, and a tissue collection cartridge configured to engage the housing. The tissue collection cartridge defines a port configured to communicate with the vacuum generator such that the vacuum generator urges cut tissue from the vacuum generator through the port into the tissue collection cartridge. The tissue collection cartridge may include at least one histological agent disposed therein, may include a fill indicator configured to indicate a fill level of tissue within the tissue collection cartridge, and/or may include a latch configured to seal the port closed.

  • Patent number: 11833077
    Abstract: A modular glaucoma implant for the treatment of glaucoma is described. Embodiments disclosed describe a glaucoma treatment device including an elongated fixation stent that allows aqueous humor to flow from the anterior chamber of the eye to the Schlemm's Canal when implanted. One or more drainage tubes can be inserted into the fixation stent such that the drainage tubes allow aqueous humor to flow from the anterior chamber of the eye to the suprachoroidal space. Surgeons can opt to add as many drainage tubes as desired based on the needed aqueous humor outflow rate.

  • Patent number: 11805998
    Abstract: A tissue biopsy device includes an input configured to receive a rotational input and to rotate in a first direction in response thereto, an outer tube, and an inner cutting member extending through the outer tube. A mechanism couples the input with at least one of the inner tube or the outer tube and/or one of the inner tube or the outer tube is coupled to the input such that rotation of the input in the first direction drives rotation of the one of the outer tube or the inner cutting member in the first direction and drives rotation of the other of the outer tube or the inner cutting member in a second, opposite direction.

  • Patent number: 11744606
    Abstract: A tissue resecting end effector includes a housing, a shaft extending from the housing, and a drive assembly operably coupled to the shaft such that a rotational input provided to the drive assembly effects the rotation and reciprocation of the shaft relative to the housing. The assembly includes a proximal portion translationally fixed and rotatably coupled to the housing and configured to receive the rotational input and to rotate relative to the housing in response thereto, a distal portion translationally and rotatably coupled to the housing and operably coupled to the proximal portion such that the rotation of the proximal portion relative to the housing effects rotation and reciprocation of the distal portion relative to the housing to thereby rotate and reciprocate the first shaft relative to the housing, and a seal member disposed on the proximal portion or the distal portion and configured to selectively establish a seal therebetween.

  • Patent number: 11596429
    Abstract: An end effector assembly of a tissue-resecting device includes an outer shaft defining a window, a drive wire extending through the outer shaft, and a distal cutting tip disposed within the outer shaft. The drive wire includes a cylindrical body and a distal end portion defining a semi-cylindrical configuration including a semi-cylindrical bottom surface and a planar top surface having a semi-cylindrical cut-out defined therein. The distal cutting tip at least partially overlaps the window and has a semi-cylindrical lumen defined by a semi-cylindrical bottom surface and an open top. The distal end portion of the drive wire is at least partially received and within the semi-cylindrical lumen with the semi-cylindrical surfaces substantially mating. The drive wire is configured to drive rotation or oscillation of the distal cutting tip relative to the outer shaft.

  • Patent number: 11517370
    Abstract: A surgical forceps includes an end effector assembly including a first jaw member and a second jaw member pivotally engaged with one another. At least one of the first or second jaw member is pivotable between a spaced-apart position and an approximated position. The first jaw member includes first and second surfaces on opposite sides thereof. The first surface is disposed in opposition to the second jaw member. The second surface includes a cutting edge disposed on a proximal portion thereof. The second jaw member includes a proximal flange having first and second raised sidewalls defining a proximal channel therebetween. The proximal channel receives the cutting edge of the first jaw member when the first and second jaw members are in the approximated position. The cutting edge of the first jaw member is exposed when the first and second jaw members are in the spaced apart position.
