Rotating valve assembly including multi-lumen spherical valve

A valve system comprising:

• a valve housing having an upper body portion and a lower body portion, the upper and lower body portions being separable and defining an internal chamber and a central axis, the valve housing having axially aligned inlet and outlet ports formed in the upper and lower body portions, respectively;
• a first spherical valve member selectively positionable within the internal chamber of the valve housing, the first spherical valve member movable in the internal chamber between first and second positions, the first spherical valve member defining first and second bores that extend through the first spherical valve member, the first bore defining a first longitudinal axis and the second bore defining a second longitudinal axis offset relative to the first longitudinal axis, the first bore supporting a first seal and the second bore supporting a second seal;
• and
• a second spherical valve member selectively positionable within the internal chamber of the valve housing to replace the first spherical valve member.

A surgical system comprising:

• a valve housing having an upper body portion and a lower body portion, the upper and lower body portions being separable and defining an internal chamber and a central axis, the valve housing having axially aligned inlet and outlet ports formed in the upper and lower body portions, respectively;
• an elongated cannula sleeve coupled to the valve housing and defining an elongated passageway extending therethrough, the elongated cannula sleeve defining a long axis aligned with the inlet and outlet ports of the valve housing;
• a first spherical valve member selectively positionable within the internal chamber of the valve housing, the first spherical valve member movable in the internal chamber between first and second positions, the first spherical valve member defining first and second bores that extend through the first spherical valve member, the first bore defining a first longitudinal axis and the second bore defining a second longitudinal axis offset relative to the first longitudinal axis, the first bore supporting a first seal and the second bore supporting a second seal;
• and
• a second spherical valve member selectively positionable within the internal chamber of the valve housing to replace the first spherical valve member.

A valve system comprising:

• a valve housing defining an internal chamber and having axially aligned inlet and outlet ports;
• a first spherical valve member seated within the internal chamber of the valve housing and defining first and second bores that extend through the first spherical valve member, the first bore defining a first longitudinal axis and the second bore defining a second longitudinal axis offset relative to the first longitudinal axis, the first bore supporting a first seal and the second bore supporting a second seal, the first spherical valve member movable between a first position wherein the first bore of the first spherical valve member is axially aligned with the inlet and outlet ports of the valve housing and the second bore of the first spherical valve member is axially misaligned with the inlet and outlet ports of the valve housing, and a second position wherein the second bore of the first spherical valve member is axially aligned with the inlet and outlet ports of the valve housing and the first bore of the first spherical valve member is axially misaligned with the inlet and outlet ports of the valve housing, wherein the first spherical valve member is mounted for axial rotation within the internal chamber about an axis extending perpendicular to the axially aligned inlet and outlet ports of the valve housing;
• a camming mechanism operatively associated with the valve housing and the first spherical valve member for moving the first spherical valve member between the first position and the second position, the camming mechanism including cam surfaces formed on an exterior surface of the first spherical valve member and a cam pin mounted for movement relative to the cam surfaces of the first spherical valve member, wherein the cam surfaces formed on the exterior surface of the first spherical valve member are defined by a pair of cam lobes oriented at angles to one another with respect to an axis of rotation of the first spherical valve member;
• and
• a second spherical valve member selectively positionable within the internal chamber of the valve housing to replace the first spherical valve member.
