Abstract: A measuring device and methods of use for measuring a section of a bowel of a patient. The measuring device includes a tubular section having a longitudinal axis and at least one wing normally projecting outward transverse to the longitudinal axis. The tubular section is configured for mounting on a conventional or robotic laparoscopic grasper adjacent the grasper's movable jaws. The at least one wing is are pivotable to a closed position so that grasper with the measuring device mounted thereon can be inserted through a conventional trocar, whereupon the at least one wing projects outward transversely to the longitudinal axis. The at least one wing is of a predetermined length to serve as a measurement tool enabling a surgeon to measure off a desired length of the bowel.

Abstract: Devices, systems, and methods described herein relate to affecting an internal diameter of a body lumen, and, in many examples, of a pylorus. A silk-based bulking agent may be injected in a pyloric tissue so as to reduce an effective inner diameter of the pylorus. A multi-part occluding agent may be injected into a pylorus on the surface of the pyloric tissue to occlude the pylorus alone or in combination with the silk-based bulking agent.

Abstract: An endoscopic instrument (10) containing a retractable tool (150, 152, 154) at its end that is articulated by engaging an actuator that moves pull wires (190) to angularly move the tip of the instrument along a plane for conducting a procedure at a target site. The tool (150, 152, 154) of instrument is linearly move from an extension position to a retracted position by another actuator. The instrument provide rotational control of the tool (150, 152, 154) and instrument tip portion (70) with a rotational actuator for rotating housings that carry both pull wires (190) and a conducting wire (160) connected to the tool (150, 152, 154).

Abstract: A robotic surgical instrument includes a housing having a shaft extending therefrom configured to receive a first end effector including jaw members moveable between a fully open position wherein the jaw members are spaced a maximum distance relative to one another and a closed position wherein a closure pressure between the jaw members is within a predetermined range. A drive rod actuates the first end effector upon translation thereof. The housing includes a spring compression assembly having proximal and distal hubs with the compression spring disposed therebetween. A jaw drive input rotates a drive gear to translate the distal hub relative to the proximal hub to compress the compression spring and actuate the end effector. Once the jaw members are fully open, the jaw drive input rotates a preset number of degrees to compress the compression spring and approximate the jaw members to a closure pressure within the predetermined range.

Abstract: A medical device includes an operating member, a hub, and an end effector. The operating member includes an actuation portion. The hub includes a channel receiving the actuation portion of the operating member. The actuation portion of the operating member moves within the channel. The end effector is movable between a closed configuration and an open configuration. Distal extension of the operating member transitions the end effector to the open configuration, and proximal retraction of the operating member transitions the end effector to the closed configuration. The medical device is formed through an additive manufacturing process.
