Abstract: A waste disposal system for receiving pharmaceutical waste material including at least one of a solid phase pharmaceutical waste material and a liquid phase pharmaceutical waste material is provided. The waste receiver includes a receiver body defining an opening. The waster receiver further includes an inner surface defining a container volume in fluid communication with the opening, and an outer surface opposite the inner surface. The outer surface defines a lock passageway separate from the opening. The system further includes a bracket adapted to be secured to a fixed surface and a locking assembly coupled to the bracket and adapted to releasably secure the waste receiver to the fixed surface. The locking assembly includes a lock housing sized to be removably positioned at least partially within the lock passageway.

Abstract: A waste receiver for receiving pharmaceutical waste material and adapted to be releasably secured to a fixed surface is disclosed. The waste receiver comprises a receiver body with a fluid absorber and a chemical composition disposed within the receiver body. The receiver body defines an opening for receiving the pharmaceutical waste material and comprises an inner surface defining a container volume in fluid communication with the opening, and an outer surface opposite the inner surface with the outer surface defining a lock passageway through the receiver body and a keyway comprising a portion of the lock passageway. The lock passageway is adapted to receive a locking assembly and the keyway is adapted to receive an engagement feature of the locking assembly to releasably secure the waste receiver to the locking assembly in a single orientation. The waste receiver also comprises a cover adapted to be coupled with the receiver body.

Abstract: An endoscopic tool for facilitating injection of fluid into a submucosal layer of tissue includes a first cannula, a second cannula, and means for attaching the first cannula to a mucosal layer of tissue. The first cannula has a distal end and a proximal end opposite the distal end. The second cannula is adapted to be coupled to a source of fluid and carries a needle at a distal end thereof. The means for attaching the first cannula to the mucosal layer draws the mucosal layer, which enlarges the submucosal layer. Fluid is then injected into the enlarged portion of the submucosal layer via the needle, thereby creating a raised portion of tissue around the injection site.

Abstract: A surgical system comprises a handpiece and a battery. The handpiece includes a body and a handpiece connector operatively coupled to the body, the handpiece connector including a first coupler. The battery includes a housing, a rechargeable cell for storing an electric charge, and a battery connector operatively coupled to the housing, the battery connector including a second coupler configured to rotatably engage the first coupler. The second coupler receives the first coupler along an axis at an initial radial position where relative axial movement between the battery and the handpiece is permitted and permits rotation of the battery relative to the handpiece from the initial radial position to a first secured radial position and a second secured radial position. Relative axial movement between the battery and the handpiece is constrained in the first secured radial position and in the second secured radial position.

Abstract: A surgical system comprises a handpiece and a battery. The handpiece includes a body, a handpiece controller, and a handpiece connector with a first coupler, a handpiece voltage terminal, and a handpiece data terminal. The battery has a housing, a cell, a battery controller, and a battery connector with a second coupler to rotatably engage the first coupler, a battery voltage terminal, and a battery data terminal. The second coupler receives the first coupler at an initial radial position and permits rotation to a first secured radial position and a second secured radial position. Rotation from the initial radial position to the first secured radial position engages the voltage terminals to transmit power between the cell and the handpiece controller, and rotation to the second secured radial position engages the data terminals to communicate data between the controllers while maintaining engagement between the voltage terminals.

Abstract: A waste disposal system with a waste receiver for receiving pharmaceutical waste material. A locking assembly is secured to a fixed surface and actuated from a locked configuration to an unlocked configuration. A lock cylinder of the locking assembly may extend forward of a front wall of a receiver body of the waste receiver to engage a locking feature of the cover in the locked configuration. A cover retention feature may prevent axial decoupling of the cover from the receiver body. An engagement feature is moved to be disengaged from the receiver body, and the receiver body is moved away from the fixed surface to disengage the locking assembly from the cover. The cover is decoupled from the cover retention feature, and coupled with the receiver body to seal the pharmaceutical waste material. The locking assembly may be removed from a lock passageway for disposal of the waste receiver.

Abstract: A waste disposal system (30) with a waste receiver (32) for receiving pharmaceutical waste material. A locking assembly (34) is secured to a fixed surface and actuated from a locked configuration to an unlocked configuration. A lock cylinder of the locking assembly may extend forward of a front wall (44) of a receiver body (36) of the waste receiver to engage a locking feature of a cover (82) in the locked configuration. A cover retention feature (124) may prevent axial decoupling of the cover from the receiver body. The receiver body may be formed from two shells (62,64). A reaction agent (150) is positioned within the container volume and spaced apart from a bottom wall of the receiver body. The reaction agent may be positioned within the container volume between the lock passageway (94) and/or a solid receiver volume, and opposing sidewalls of the receiver body. A support may maintain the position of the reaction agent within the container volume.

Abstract: An endoscopic tool for facilitating injection of fluid into a submucosal layer of tissue includes a first cannula, a suction source, a fluid lumen, and a second cannula. The first cannula has a suction surface disposed at a distal end, and defines a suction lumen. The suction source is coupled to the first cannula and creates a negative pressure within the suction lumen. The second cannula is disposed in a fluid lumen separate from the suction lumen, is adapted to be coupled to a source of fluid, and carries a needle at a distal end thereof. The tool draws the mucosal layer via the suction, which enlarges the submucosal layer, and injects a fluid into the enlarged portion of the submucosal layer via the needle, thereby creating a raised portion of tissue around the injection site.

Abstract: Devices and methods for gastrointestinal bypass are described. A gastrointestinal bypass device includes a gastrointestinal cuff and a gastrointestinal sleeve. The cuff may be configured to be attached in the esophagus, and may be sufficiently flexible to expand and collapse to conform with the inside of the esophagus to allow the esophagus to function substantially normally. The sleeve is configured to be coupled to the cuff, and may be made of a material that is floppy or flaccid but does not substantially expand radially.
