A tubular tissue transformer (TTT) for a tubular tissue structure. The tubular tissue transformer has a plurality of leaves and a plurality of retainers on each of the plurality of leaves. Each retainer retains the tubular tissue structure on the respective leaf. Also provided are a coupling system to coupling tubular tissue structures together and tools and methods for attaching and widening otubular tissue structures.

A transfer device for a living organism for placing an object in a living organism comprises a plurality of movable units. Each movable unit comprises one or more needles extending in a first direction. Each needle has a cylindrical shape capable of storing the object therein. Each movable unit is movable in the first direction.

Systems and methods for effecting bariatric procedures are disclosed. Each system includes an instrument, a control valve and, optionally, a suction controller. The instrument is in the form of an elongated, flexible member having a distal end portion arranged for anchoring the instrument in the patient's stomach and for enabling fluids to be removed from the patient's stomach. Suction is applied to the patient's stomach by the distal end portion of the instrument to drain gastric fluids and to bring adjacent portions of the patient's stomach into engagement with the instrument to provide a visually perceptible delineation line along which a portion of the stomach may be resected, sealed and tested.

A retrieval system for thrombus and foreign body removal.

Mechanical thrombectomy apparatuses including an inverting, rolling conveyor region (“tractor”) at the distal end that are configured to grab and remove thrombus material. In particular, described herein are mechanical thrombectomy apparatuses that are adapted to prevent premature deployment of the tractor, e.g., by including a tractor hold (e.g., a housing, a lock, a clamp, etc.) or the like to secure the outer end of the tractor against and/or relative to the elongate inversion support.

A method for closure of the left atrial appendage (LAA), including: placing an LAA reshaper in contact with an LAA wall or near the LAA wall; invaginating at least a portion of the LAA into the left atrium (LA); reshaping by the LAA reshaper the LAA during the invagination; fastening the invaginated at least a portion of said LAA; and retracting the LAA reshaper from the LAA

The present disclosure provides systems and devices for monitoring the pressure within a negative pressure system, such as a suction cannister. In one aspect, the system includes an anchor configured for positioning within an intestine of the patient at the anastomosis site and a source of negative pressure, such as a suction cannister, fluidly coupled to the anchor. A portable alarm device is coupled to the suction cannister and includes a trigger for detecting the pressure therein. A signal device emits a signal when this pressure is above a threshold level to ensure that the anchor remains securely in contact with the walls of the intestines at the anastomosis site. The alarm device includes a handle to allow a patient to grasp and carry the suction cannister, providing critical patient mobility during the recovery period.

A device is configured for use in negative pressure wound therapy (NPWT). The device includes a tube having a tube proximal end and a tube distal end and A coil having a plurality of windings extending from a coil proximal end to a coil distal end. The coil distal end is coupled to the tube proximal end in a manner that enables application of a negative pressure from within the coil through the coil to tissue surrounding the coil. The coil comprises a space between adjacent ones of the plurality of windings, the space having a predetermined dimension.

Systems and methods for effecting bariatric procedures are disclosed. Each system includes an instrument, a control valve and, optionally, a suction controller. The instrument is in the form of an elongated, flexible sizing member having a distal end portion arranged for anchoring in the patient's stomach and for enabling fluids to be removed from the patient's stomach. The elongated flexible sizing member is configured to produce near infrared fluorescence to facilitate its location within the patient's stomach and to provide visual information about location of certain relevant internal anatomical features. Suction is applied to the patient's stomach by the distal end portion of the instrument to drain gastric fluids and to bring adjacent portions of the patient's stomach into engagement with the instrument to provide a visually perceptible delineation line along which a portion of the stomach may be resected, sealed and tested.

A surgical instrument includes an end effector assembly including first and second grasping components each defining a tissue-contacting portion. One or both of the first or second grasping components is movable relative to the other between an open position and a closed position. In the closed position, the first and second tissue-contacting portions cooperate to define a grasping area therebetween. One or both of the first or second grasping components is configured to apply energy from the tissue-contacting portion thereof to tissue disposed within the grasping area to treat tissue. The tissue-contacting portion of the first grasping component defines a first opening therethrough. The first opening is disposed within the grasping area and in communication with a first lumen defined at least partially through the first grasping component. The first lumen is adapted to connect to a source of vacuum to enable aspiration through the first opening.
