An aspiration system includes a pump and a control system in communication with the pump. The control system includes a microcontroller, an antenna configured to receive a signal, and a pump control board in communication with the microcontroller. The antenna is in communication with the microcontroller. Upon receiving the signal, the pump control board operates the pump to create negative pressure according to the signal.

The devices and methods described herein relate to jointless construction of complex structures. Such devices have applicability in through-out the body, including clearing of blockages within body lumens, such as the vasculature, by addressing the frictional resistance on the obstruction prior to attempting to translate and/or mobilize the obstruction within the body lumen.

A tissue specimen removal device comprises a specimen bag; a flexible ring, the flexible ring configured to form a top opening of the specimen bag; a cannula assembly comprising: an inner tube portion and an outer tube portion. The device may further comprise a connector carrier, the connector carrier configured to retain at least one connector housing, the at least one connector housing comprising one or more connector portions and reside within an interior of the connector carrier, and wherein the connector carrier can be moved from a position within the cannula assembly to outside the cannula assembly.

A tissue removal tool for use with an endoscope. The tool includes a loop formed by a piece of wire. The loop is movable between an open position and a closed position. The shape of the loop is defined in the open position by a proximal portion and a distal portion. The piece of wire may have a cross-sectional height in the proximal portion unequal to a cross-sectional height in the distal portion.

An access system includes a proximal handle, an overtube coupled to the handle, and an endoscope port extending through handle and overtube sized for receiving an endoscope therethrough. The overtube includes anatomic wall securing system that secures a distal portion of the overtube within a hole in the anatomic wall. The overtube is provided with a shaped distal portion or a controllably shapeable distal portion that aids in directing an endoscope inserted through the port to a particular location within the peritoneal cavity. The access system includes a system for insufflating/deflating the peritoneal space separately from the body cavity accessible via a natural orifice. The access system includes a closure system to cinch closed the hole made in the anatomical wall after the access system has been removed from the hole. Methods are provided for inserting the access system through the anatomical wall to perform intra-abdominal surgery.

Apparatus and methods for internal surgical procedures are disclosed. The apparatus and methods may involve supporting internal body locations, creating submucosal separations (blebs), and/or for resecting mucosal tissue separated from underlying tissue by a bleb.

Embodiments of this invention relate to endoscopic and laparoscopic surgical instruments. More specifically, embodiments of this invention relate to an open loop polypectomy system including a means for securely closing the loop. In some embodiments, the open loop polypectomy system comprises a snare wire and a capture mechanism wherein, when the snare wire is advanced, the snare wire extends from a distal portion of the open loop polypectomy system along a path passing through the capture mechanism. After the snare wire has advanced through the plane of the capture mechanism, retraction of the capture mechanism secures the snare wire, creating a formed loop around a target tissue. Retraction of at least one of the snare wire and capture mechanism contracts the formed loop, resecting the target tissue.

An apparatus is provided that is operable in different modes to perform various functions for treating a body lumen. The apparatus includes a shaft including proximal and distal ends, a lumen extending there between, and a balloon on the distal end. The apparatus includes a valve on the distal end that selectively opens or closes an outlet communicating with the lumen. With the valve open, fluid introduced into the lumen exits the outlet into a body lumen. With the valve closed, fluid introduced into the lumen expands the balloon. The valve may be biased to be closed, e.g., by a spring element disposed within the balloon. Optionally, the apparatus also includes an actuator for expanding a helical member within the balloon interior, e.g., either before or after expanding the balloon, such that the helical member and balloon may adopt an expanded helical shape for removing material within a body lumen.

Vascular treatment and methods include a plurality of self-expanding bulbs and a hypotube including interspersed patterns of longitudinally spaced rows of kerfs. Joints between woven structures and hypotubes include solder. Woven structures include patterns of radiopaque filaments measureable under x-ray. Structures are heat treated to include at least shapes at different temperatures. A catheter includes a hypotube including interspersed patterns of longitudinally spaced rows of kerfs. Heat treating systems include a detachable flange. Laser cutting systems include a fluid flow system.

An interactive control unit is disclosed. The interactive control unit includes an interactive touchscreen display, an interface configured to couple the control unit to a surgical hub, a processor, and a memory coupled to the processor. The memory stores instructions executable by the processor to receive input commands from the interactive touchscreen display located inside a sterile field and transmit the input commands to the surgical hub to control devices coupled to the surgical hub located outside the sterile field.
