  • Publication number: 20240138970
    Abstract: The present embodiments provide an expandable mesh comprising a first coupling element, a second coupling element, and an intermediate portion disposed between the first coupling element and the second coupling element. Proximal retraction of the first coupling element relative to the second coupling element causes the intermediate portion to flare out to an enlarged width. In one embodiment, the first coupling element comprises a first tube and the second coupling element comprises a second tube.

  • Patent number: 11337723
    Abstract: The present embodiments provide apparatus and methods for treating tissue by applying a force to the tissue. In one embodiment, the apparatus comprises a deployable segment having proximal and distal regions, a main body extending therebetween, and a loop member formed at the distal region of the deployable segment. A cannula having a bore is dimensioned to circumferentially surround at least a portion of the main body at a location proximal to the loop member, and a spring member is disposed between the cannula and the loop member. The proximal end of the spring member is affixed to the cannula, and the distal end of the spring member is movable to apply a compressive force to adjust the size of the opening of the loop member and compress tissue disposed within the opening of the loop member. In an alternative embodiment, the cannula is omitted, and a diameter of the loop member is configured to be reduced and increased any number of times before final deployment of the deployable segment.

  • Publication number: 20220022938
    Abstract: An electrosurgical system may include a medical delivery device and an electrosurgical device to perform an electrosurgical procedure. The electrosurgical device may have a monopolar configuration. An outer surface of the medical delivery device may include a conductive portion that is part of a return path for a bipolar configuration. Current may be supplied through an active member of the electrosurgical device to perform the procedure. After passing through tissue, the current may be drawn to the electrode portion of the medical delivery device to complete the circuit.

  • Patent number: 10244921
    Abstract: The present embodiments provide apparatus for facilitating endoscopic resection of tissue. The apparatus comprises proximal and distal barrels. The proximal barrel is adapted to be coupled to an endoscope. A cutting member is disposed within a lumen of the distal barrel and configured to resect a segment of tissue. In one embodiment, a central longitudinal axis of the proximal barrel is radially offset from a central longitudinal axis of the distal barrel, thereby allowing the cutting member to be centered relative to the working lumen of the endoscope. Additionally, the cutting member may comprise at least one viewing window that permits endoscopic visualization of tissue distal to the distal barrel when the cutting member is disposed within the distal barrel.
