Surgical clamp devices and methods especially useful in cardiac surgery

A clamping and fluid delivery device for occluding a vessel during a surgical procedure and for simultaneously delivering at least one fluid to said vessel, the clamping and fluid delivery device comprising:

• first and second opposed vessel engagement arms having opposed sealing surfaces adapted to extend on the outside of the vessel and movable between clamped and unclamped positions, and
• an internal core portion having a distal end with a sealing surface and opposite side surfaces comprising sealing surfaces, said internal core portion adapted to be inserted transversely into the vessel through an incision in a wall of the vessel and further configured to be received between said opposed vessel engagement arms when in the clamped position such that each of said sealing surfaces of said core portion sealingly engages the wall of the vessel to inhibit fluid flow across the core portion within the vessel and each of said sealing surfaces of said core portion is opposed by a respective sealing surface of one of said arms bearing against the outer surface of the vessel wall.

A clamping device for occluding a vessel during a surgical procedure, the clamping device comprising:

• an internal core portion adapted to be inserted transversely into the vessel through an incision in a wall of the vessel,
• an external clamping portion adapted to extend on the outside surface of the vessel, at least one of the core portion and the external clamping portion being movable with respect to the other to clamp the wall of the vessel between the core portion and the external clamping portion, and
• a seal member disposed for movement along said core portion and configured to seat against the vessel within the incision to inhibit fluid leakage from the vessel.

A clamping device for occluding a vessel during a surgical procedure, the clamping device comprising:

• an internal core portion having a rounded distal sealing end adapted to be inserted transversely into the vessel through an incision in a wall of the vessel and to sealingly engage a portion of the wall generally across from the incision, and
• an external clamping portion including first and second opposed vessel engagement arms adapted to extend on the outside of the vessel, at least one of said arms being movable toward the other into a clamped position to clamp the wall of the vessel between said internal core portion and said arms, said arms further including distal tips having internal clamping surfaces curved to generally follow the curvature of the rounded distal sealing end of said internal core portion when in the clamped position thereby effectively clamping the vessel while inhibiting the loosening or breakage of plaque retained on internal surfaces of the wall of the vessel.

A clamping device for occluding a vessel during a surgical procedure, the clamping device comprising:

• an internal core portion adapted to be inserted transversely into the vessel through an incision in a wall of the vessel,
• an external clamping portion adapted to extend on the outside of the vessel, at least one of said core portion and said external clamping portion being movable with respect to the other to clamp the wall of the vessel between said internal core portion and said external clamping portion, and
• a valve mechanism carried by said internal core portion for disposition within said vessel and for selectively allowing fluid flow within the vessel between opposite sides of said internal core portion.
