Devices, systems, and methods for therapeutically treating tissue. The devices and methods are suitable for minimally invasive surgery or open surgical procedures. More particularly, methods and devices described herein permit accessing and/or treating areas of tissue with a therapeutic device having a hood member with a plurality of channels located therein for applying a vacuum and cooling the areas of tissue as energy is delivered through electrodes located adjacent to or in the hood member.

A medical device for use in the creation of a temporary pneumoperitoneum includes a substantially dome-shaped body having a vacuum port providing a fluid passageway between an underside of the dome-shaped body and an upside of the dome-shaped body. The medical device includes a first grasping wing and a second grasping wing circumferentially opposite one another. The combination of the first grasping wing and the second grasping wing is configured to enable a user to single-handedly place the medical device at a surface of a patient. The medical device includes a plug disposed within an aperture of the dome-shaped body. The plug includes a first frustoconical aperture facing an opposite direction than a second frustoconical aperture to form a substantially hour-glass shape. The plug is configured to provide a penetrable barrier from the outside surface of the hard-body dome to the inside surface of the hard-body dome.

A collapsible, clamping and/or steerable apparatus in conjunction with negative pressure system and methods for using such an apparatus are described. Preferred embodiments of the invention have lengths and bent and/or increase their curvatures along their lengths, by preferentially contracting and transforming upon negative pressure.

A gastric tube for use in a bariatric surgical procedure includes an elongate tube and a movable component supported on an outer surface of the elongate tube. The elongate tube has a non-circular cross section along at least a portion of a length of the elongate tube. The movable component is movable between an unexpanded configuration and an expanded configuration. In the unexpanded configuration, the movable component is disposed in abutting engagement with the outer surface of the elongate tube. In the expanded configuration, the movable component bows outwardly from the outer surface of the elongate tube.

A device for occluding an atrial appendage includes a catheter-deliverable epicardial implant that is detachably secured to a delivery device. The implant includes an inflatable cuff that is positionable about the atrial appendage to an extent that, when adjustably inflated, the cuff physiologically occludes the atrial appendage. Such occlusion addresses health risks associated with atrial fibrillation and cardiac rhythm disorder.

A rectal band ligation device and a method of operating the band ligation device. In one embodiment, the band ligation device includes: (1) a handle having a trigger associated therewith, (2) an extension tube extending from the handle and terminating in a head, (3) at least two openings in the head, (4) hollow pistons located in the openings and configured to move relative thereto between an extended position in which ends of the pistons are exposed through the openings and a retracted position, gaps between corresponding openings and hollow pistons being less than cross-sectional widths of elastic members stretched around the ends and (5) an actuating rod coupling the trigger and the pistons and configured to cause the pistons to move from the extended position to the retracted position.

Methods, systems, and devices are described for fabricating, providing, and using an orogastric tube. The orogastric tube may have, among other things: a proximal end section; a distal end section opposite the proximal end section and having a flexible, resilient curved portion; at least one sump channel extending from the proximal end section along a pre-determined length of the orogastric tube into the distal end section; at least one suction channel extending from the proximal end section along a pre-determined length of the orogastric tube into the distal end section; and optionally at least one balloon channel extending from the proximal end section along a pre-determined length of the orogastric tube to the distal end section. The optional balloon channel is in communication with an expandable balloon in the distal end section; and a main channel encloses a pre-determined length of the sump channel, the suction channel, and, if present, the balloon channel.

An epicardial implant having a positioning device that defines an open interior. The positioning device is configured to be detachably coupled with an implant delivery device such that the positioning device may be detached from the implant delivery device after the implant is in place about an atrial appendage. The positioning device has first and second sides with a distal end that couples the first and second sides. The implant includes an expandable cuff coupled with the positioning device. The positioning device is configured to selectively move the expandable cuff toward and away from an atrial appendage to position the expandable cuff in a desired position relative to the atrial appendage. The expandable cuff is expandable into at least a portion of the open interior of the positioning device to physically occlude a base of the atrial appendage following placement of the expandable cuff into the desired position.
