Patent number: 11045341Abstract: Apparatus for manipulating and securing tissue are described herein. In creating tissue folds within the body of a patient, a tissue manipulation assembly may generally have an elongate tubular member, an engagement member slidably disposed through the tubular member and a distal end adapted to engage tissue via a helical member, tissue stabilizing members positioned at the tubular member distal end which are adapted to stabilize tissue therebetween, and a delivery tube pivotable about the tissue stabilizer. The stabilizing members can be adapted to become angled relative to a longitudinal axis of the elongate tubular member. Moreover, one or all the articulation controls and functions can be integrated into a singular handle assembly connectable to the tissue manipulation assembly via a rigid or flexible tubular body.Type: GrantFiled: July 24, 2018Date of Patent: June 29, 2021Assignee: USGI MEDICAL, INC.Inventors: Vahid Saadat, Richard C.

Patent number: 9585651Abstract: Methods and apparatus for securing and deploying tissue anchors are described herein. A tissue manipulation assembly is pivotably coupled to the distal end of a tubular member. A reconfigurable launch tube is also pivotably coupled to the tissue manipulation assembly, which may be advanced through a shape-lockable endoscopic device, a conventional endoscope, or directly by itself into a patient. A second tool can be used in combination with the tissue manipulation assembly to engage tissue and manipulate the tissue in conjunction with the tissue manipulation assembly.
