    Abstract: A device for fluidizing and delivering a powdered agent, including a canister extending longitudinally from a first to a second end and defining a space within which a powdered agent is received, an inlet coupleable to a gas source for supplying gas to the space to fluidize the powdered agent to create a fluidized mixture, an outlet via which the gas mixture is delivered to a target area, a tube extending from the outlet into the interior space, the tube including a slot extending through a wall thereof so that gas mixture is passable from the interior space through the outlet via the second end and the slot, and a door movably coupled to the tube so that the door is movable over the slot to control a size of the slot open to the interior space of the canister.

    IPC: A61F5/00

    Abstract: The present disclosure relates generally to the field of medical devices and medical device delivery. In particular, the present disclosure relates to medical devices, systems, and methods for delivering a barrier device within a body lumen of a patient, such as the GI tract. For example, a barrier device may include a distal self-expanding stent. A tubular barrier may have a proximal end, a distal end, and a lumen extending therethrough. The distal stent may be disposed at the distal end of the tubular barrier. An anchoring self-expanding stent may be disposed at the proximal end of the tubular barrier.

    Abstract: This disclosure relates generally to the field of devices and procedures for forming an opening between adjacent tissue structures. For example, in an embodiment, a system for forming an opening between body lumens may include a delivery catheter. A first access element may be configured to be positioned against a first body lumen disposed about a distal end of the catheter. A second access element having an outer diameter that substantially matches an outer diameter of the first access element may be disposed about the distal end of the catheter. The second access element may be configured to be positioned against a second body lumen and axially aligned with the first access element. A filament may be electrically coupled to one or both of the first and second access element.

    IPC: A61M25/10

    Abstract: A medical device includes a sheath having a proximal end, a distal end, and at least one lumen extending from the proximal end to the distal end, and a balloon at the distal end of the sheath and having an inflated configuration and a deflated configuration. The balloon defines at least one space radially inward of an exterior surface of the balloon, the at least one space configured to retain a material, and the transition of the balloon from the deflated configuration to the inflated configuration delivers the material from the at least one space to a target site in a body.

    Abstract: Compositions including a plurality of particles that may be prepared from a chitosan salt and methods for preparing the same. The plurality of particles may have an average diameter ranging from about 100 μm to about 750 μm, such as from about 150 μm to about 500 μm; a steepness value ranging from about 30 to about 90; and an average aspect ratio greater than 0.6. The plurality of particles may be substantially spherical in shape, for example. Methods of preparation include electrospraying a chitosan salt solution through a needle.
