An endoscopic foam delivery catheter comprising a dissolution solution and methods of their use for treating pancreatic necrosis are disclosed.

A distal end of a medical device may comprise a tube configured to be coupled to a source of suction; and a porous body coupled to the tube. The porous body may have a wall with an inner surface and an outer surface. The distal end may include a cavity, such that a gap extends from an outer surface of the tube to the inner surface of the porous body.

The present disclosure relates to a gastrointestinal delivery device of a chitosan dressing, where the delivery device is capable of stop bleeding, in particular in connection with TURP procedures. The delivery device may be used in all gastrointestinal bleeding applications and can be used with a biocompatible, foldable, thin profile, chitosan dressing. Various aspects of the device and its uses are provided herein.

A conformable surgical tampon for disposition into and removal from an anatomical cavity of a mammalian patient by a doctor to absorb and collect bodily fluids. The tampon comprises an absorbent chassis material and a plurality of spaced apart positioning strings attached to the chassis. The spaced apart positioning strings are operative to selectively position the conformable nasopharyngeal tampon within an anatomical cavity of a patient responsive to manipulation of a positioning string by a surgeon. The tampon is particularly suited for nasopharyngeal surgery.

Disclosed are devices, systems and methods for a removeable and replaceable gasket and attached patty or sponge for a surgical (or dental) suction cannula which facilitates the safe and effective removal of blood and other bodily fluids from a body cavity while allowing manipulation and/or management of the sponge and/or various tissues therein. These devices protect delicate anatomic structures from excessive negative pressure while allowing effective suctioning of fluid and debris from the operative field.
