Abstract: A medical valve may comprise a valve stem and an operation portion. The operation portion may include a stationary portion, a movable portion which is movable relative to the stationary portion and fixed relative to the valve stem, a seal disposed between the stationary portion and the movable portion, and a biasing member. Movement of the movable portion in a first direction may cause deformation of the biasing member, such that a restorative force of the biasing member urges movement of the movable portion in a second direction opposite the first direction. A frictional force between the seal and one of the stationary portion and the movable portion resists the movement of the movable portion in the second direction.

Abstract: According to one aspect, a tissue fastening device may include a handle assembly including at least two actuators. The tissue fastening device may also include a first body extending distally from the handle assembly and defining a longitudinal axis. The tissue fastening device may also include a fastening device coupled to a distal end of the first body. The fastening device may include a longitudinal body including a channel, a cartridge configured to include a plurality of fasteners, a longitudinal channel configured to receive a device for cutting tissue, an anvil rotatable relative to the cartridge, and a fastener actuator. The fastener actuator may be coupled to one actuator of the at least two actuators and configured to move proximally relative to the cartridge to deploy the plurality of fasteners from the cartridge.

Abstract: A valve for use in an endoscope may comprise a proximal valve stem member having a first lumen extending from a proximal opening at a proximalmost end of the proximal valve stem member to a distal opening at a distalmost end of the proximal valve stem member. A distal valve stem member may have a second lumen with a proximal opening at a proximalmost end of the distal valve stem member. The proximalmost end of distal valve stem member may be received within the distal opening of the first lumen. The distal valve stem may be movable relative to the proximal valve stem.

Abstract: According to one aspect, an instrument may include a sheath having a distal end. The instrument also may include a fluid cannula at the distal end of the sheath. The instrument also may include a cutting electrode at the distal end of the sheath. At least one of: (i) an exterior surface of the fluid cannula, and (ii) a cutting electrode surface that faces the exterior surface, is longitudinally slidable along the other of the exterior surface and the cutting electrode surface during movement of at least one of the cutting electrode and the fluid cannula relative to the other of the cutting electrode and the fluid cannula.
