Abstract: A multi-working channel device with a cylindrical assembly having a distal end, a proximal end, an interior space, and an aperture. The multi-working channel device also has a longitudinally extending tube with a proximal end, a distal end that is coterminous with the distal end of the cylindrical assembly, and a balloon. The multi-working channel device also utilizes a stylet having a proximal end and a distal end that is connected to the balloon. The stylet can be adjusted between a home position and an active position. In the home position, the balloon is at least partially within the longitudinally extending tube. Alternatively, the active position deploys the balloon from the longitudinally extending tube. The stylet selectively urges the balloon to the active position, facilitating employment of the alimentary engagement device. In addition, the balloon is selectively inflated through the longitudinally extending tube.

Abstract: An adjunct non-pneumatic operative field device having a pair of selectively lockable, slidingly engaged nested tubes. The pair of tubes consist of an inner tube and an over tube. Each tube has a proximal end and a distal end. The distal ends could be tapered. In addition, this adjunct non-pneumatic operative field device has a lock. The adjunct non-pneumatic operative field device has two interchangeable configurations: a home position and an active position. In the home position the two distal ends are either coterminous or adjacent to each other. Alternatively, in the active position, the two distal ends are spaced apart by a user. And the active position engages the lock, which suppresses relative movement between the selectively lockable, slidingly engaged nested tubes. The active position also consists of expansion of the over tube to create an operative secure field.

Abstract: Provided is an alimentary engagement device that may be used for certain medical procedures such as colonoscopies and endoscopies. The alimentary engagement device includes a conduit that is fitted over a medical instrument such as a colonoscope or an endoscope as it is inserted within a body cavity. On the outer surface of the conduit is a balloon which may be expanded to engage the walls within the interior of the cavity. The interior of the conduit includes a seal which has an aperture for allowing a medical instrument to pass through.
