Abstract: A handle assembly for controlling a steerable catheter includes a handle extending about a longitudinal axis from a proximal end to a distal end. A lumen extends through the handle to a distal tip extending outwardly from the distal end of the handle and a pair of control wires are interconnected to the distal end of extend the lumen. A lever assembly is disposed within the handle and includes a lever rotatable about a lever axis to control deflection of the distal end of the lumen. The lever assembly includes a first and second gear assembly disposed in opposing relationship to one another and offset relative to the longitudinal axis for allowing the lumen to pass therebetween. Each of the gear assemblies are interconnected to one of the pair of control wires to individually pull a respective one of the control wires in response to rotation of the lever.

Abstract: A gastrectomy device includes an elongated member defining a centerline that extends through proximal and distal ends thereof. A shape modification member coupled to the elongated member is movable relative to the centerline of the elongated member. The shape modification member is movable between a first state, adjacent to the elongated member, and a second state, spaced from the elongated member. The shape modification member conforms to a portion of a patient's stomach in the second state.

Abstract: A medical valve assembly includes a tube extending between proximal and distal tube ends. A plunger plate extends radially from the distal tube end, and a valve housing surrounds the tube and extends between proximal and distal valve housing ends. The valve housing includes a flange extending radially inwardly from the distal valve housing end and disposed in spaced relationship with the plunger plate to define a distance dimension D extending therebetween. An elastomeric seal is compressed between the plunger plate and the flange to establish a closed condition of the medical valve assembly. The elastomeric seal axially moves one of the valve housing and the tube relative to the other when a medical device is inserted into the medical valve assembly to automatically increase the distance dimension and establish an open and sealed condition of the medical valve assembly with the inserted medical valve.

Abstract: A modular handle assembly includes a dial rotatably connected to a handle and rotatable about a first rotary axis. A first gear arm extends from the dial and terminates at a first traction surface. A second gear arm is connected to the handle and rotatable about a second rotary axis that is parallel to the first rotary axis. The second gear arm terminates at a second gear tip that presents a second traction surface disposed against the first traction surface such that rotation of the dial in a first rotary direction effectuates rotation of the second gear arm in an opposite direction. A cam is coupled with at least one of the first and second gear tips and presents at least one deflection surface for deflecting a deflection wire during rotation of the dial to steer a distal end of a steerable catheter containing the deflection wire.

Abstract: A medical valve assembly includes a tube extending between a first and second tube end along an axis, and a plunger plate extends radially from the second tube end. A valve housing surrounds the tube and includes a radially inwardly extending flange. A compression member is biased against the plunger plate and compresses an elastomeric seal from a non-compressed condition to a compressed condition to establish a sealed condition of the medical valve assembly. An inner surface of the elastomeric seal in the non-compressed condition has a plurality of planar portions and a plurality of radiused portions, with adjacent planar portions interconnected with one of the radiused portions to improve a closure of the elastomeric seal during compression. The inner surface preferably includes three planar portions and three radiused portions to define a generally triangular-shaped inner surface as viewed in cross section in the non-compressed condition.
