Abstract: An ostomy device includes a pouch, a bag, and a securing mechanism. The pouch extends from a proximal end attachable to skin surrounding a stoma exit of a patient to a distal end. The pouch includes an outlet accessible to the patient. The bag is housed within the pouch and extends from a proximal end interfacing with the exit to a distal end. The bag includes separatable sections. The mechanism secures, relative to the pouch, remaining sections that are proximal of a distal-most section. The bag is configured so that, when the distal-most section is filled with waste from the exit, the distal-most section may be detached from the remaining sections and a distal-most one of the remaining sections is securable by the mechanism relative to the pouch in a position to interface with the exit to receive further waste from the exit.

Abstract: An ostomy device includes an inflatable member and a tubing. The inflatable member defines a hole extending therethrough. The inflatable member is configured to extend about a portion of an intestine proximate a stoma. In an operative configuration, the inflatable member movable between a deflated configuration, in which the stoma is maintained in an open position, and an inflated configuration, in which the inflatable member expands to decrease a size of the hole such and close the stoma. The tubing extends from a first end connected to the inflatable member to a second end. A channel of the tubing is in communication with an interior of the inflatable member such that inflation fluid is configured to flow through the tubing to move the inflatable member between the deflated and inflated configurations.

Abstract: The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to an electrosurgical surgical tip that includes a conductive and low-profile cutting surface to provide high current density radiofrequency energy with minimal thermal damage to surrounding tissues. For example, an electrosurgical tip of the present disclosure may include a ring of conductive material sputter-coated around a distal opening of a non-conductive base component and a strip of conductive material sputter-coated along a longitudinal axis of the non-conductive base component.

Abstract: A multi-electrode energy-delivering assembly configured to be delivered in a generally elongate delivery configuration. The multi-electrode energy-delivering assembly includes one or more spaced apart electrodes of a first polarity. The electrodes may be spaced apart axially and/or may be expanded apart from one another upon deployment. In some aspects, the electrodes may be electrically activated independently of one another.

Abstract: Bipolar or monopolar adjustable energy-delivering assemblies. The assemblies are configured for transluminal (e.g., endoscopic) delivery within a patient. A first energy-delivering member defines a first electrode portion formed of an electrically-conductive material so that energy may be delivered to the first energy-delivering member to create an energy field along the first electrode portion to apply to a target site within a patient. The first energy-delivering member may define a lumen therethrough allowing delivery of materials distally therethrough to a target site and/or allows materials from the target site to be aspirated proximally therethrough. Optionally, a second energy-delivering member and a second insulation member form a second electrode portion. Optionally, either or both electrode portions may be adjustable. Additionally or alternatively, the first electrode portion and the second electrode portion are adjustable with respect to each other.

The sheath may be configured to change position by sliding along the member to insulate a portion of one or both of the first and second electrode.

Abstract: Stents, auxiliary compressive structure for stents, and techniques to avoid migration of a deployed stent are provided. An auxiliary support structure can be provided to apply compressive force on the flanges of the stent further compressing the stent or to provide axial or radial support for the flanges. The auxiliary support structures can be integrated into the stent or provided as separate device.
