Abstract: Compression anastomosis devices having a plurality of distinct pressure profile zones on the surface of the device. The anastomosis devices may be comprised of a plurality of magnetic connecting members arranged in an annular geometry, e.g., a polygon or circle. The anastomosis device may also be a continuous, non-segmented magnet, or other compression anastomosis device. The compression anastomosis device is deployed into a body lumen, e.g., endoscopically and/or laparoscopically, at a target site. A second compression anastomosis device is placed at an adjacent target site in an adjacent lumen. The compression anastomosis devices are brought together and mate, e.g., magnetically, creating an anastomosis.

Abstract: A magnetic compression anastomosis device comprises a plurality of interconnected vertebrae including a first vertebra and a second vertebra, wherein each of the first vertebra and the second vertebra is a multipiece vertebra comprising a magnet at least partially encapsulated by a vertebra skin, and wherein the first vertebra and the second vertebra are interconnected by a cylindrical roller and at least one flex element, the roller and the at least one flex element at least partially encapsulated by the first vertebra skin and the second vertebra skin, the roller configured to allow the first and second vertebra to pivot through a predetermined range of rotation in a device plane between at least a delivery configuration and an assembled configuration while constraining movement in other degrees of freedom, the at least one flex element biasing the first and second vertebra toward the assembled configuration.

Abstract: Various embodiments incorporate an “end effector” in a magnetic anastomosis device system. The end effector is located between the handle of an endoscope or laparoscope and the distal end of the catheter. The end effector engages with and secures the magnetic anastomosis device assembly within a body lumen. The end effector is able to hold a magnetic device or devices with a tensile strength of 0-10 lbs. The end effector is small enough that two instruments of 1.8 mm diameter or smaller may be placed in a 3.7 mm working channel of an endoscope.

Abstract: The invention provides systems, devices, and methods for the delivery, deployment, and positioning of magnetic compression devices at a desired site so as to improve the accuracy of anastomoses creation between tissues, organs, or the like.

Abstract: Embodiments of the disclosure include methods and systems for attaching an articulation section. In an embodiment, a medical instrument includes a first tubular member including a first end. The medical instrument also includes a second tubular member including a first end. The second tubular member includes a plurality of layers including an inner layer and a first layer including a fluorinated material. The inner layer includes a first section disposed under the first layer and a second section extending out from under the first layer. A portion of the first tubular member overlaps and is bonded to at least a portion of the second section of the inner layer of the second tubular member.

Abstract: Various types of otomy control devices that secure a periphery and/or adjacent tissue of a target otomy site and maintain the size of an otomy through a single wall of a vessel, organ, or lumen within the body. Among other things, this can reduce unintentional trauma, dilation, contraction, or locomotion of an otomy during a surgical procedure. They also can serve a beneficial purpose of allowing immediate communication between lumens before the complete creation of A permanent anastomosis. In some embodiments, magnetic compression anastomosis devices and/or other devices can be deployed through a channel of the otomy control device such as for deployment in a distal lumen.
