Prosthetic valve holder

Claim 2

A holder of a valve prosthesis implantable in a patient's circulatory system, comprising: a first arm and a second arm hinge-joined to each other; said first arm having a first end and a second end; said second arm having a first end and a second end; handles provided at said first ends of said first and second arms; at least three similar working jaws, which can be brought together for a valve prosthesis to set thereon, and be brought apart for said valve prosthesis to hold thereto, thus giving said valve at least three bearing points; said working jaws pivotally mounted at said second end of said first arm and having vacant ends which, when brought apart, define a circle along their perimeter; a plate having a plurality of slots equal in number to that of said working jaws; said plate being secured at said second end of said second arm in such a manner that one of said working jaws is passed through each of said slots so that when said working jaws are being brought together or apart, they are free to traverse along said slots.

Claim 3

A holder as claimed in claim 1, wherein said working jaws are curved, and for said jaws to be brought together and apart, the edge of each of said slots slides along said curved working jaw passing through said slot.

Claim 4

A holder of a valve prosthesis implantable in a patient's curculatory system, comprising: a first arm and a second arm hinge-joined to each other; said first arm having a first end and a second end; said second arm having a first end and a second end; handles provided at said first ends of said first and second arms; at least three similar working jaws, which can be brought together for a valve prosthesis to set thereon, and be brought apart for said valve prosthesis to hold thereto, thus giving said valve at least three points of bearing; said working jaws being articulated to said second end of said first arm and having vacant ends which, when brought apart, form a circle along their perimeter; said at least three working jaws, each of them being arranged at an angle of 90° to a longitudinal geometric axis of the holder; said working jaws being of a curved shape; a plate having a plurality of slots equal in number to that of said working jaws; said plate being secured at said second end of said second arm in such a manner that one of said working jaws is passed through each of said slots so that when said working jaws are being brought together or apart, they are free to traverse along said slots, and the edge of each of said slots slides along said curved working jaw passing through said slot.

Claim 5

A holder of a valve prosthesis implantable in a patient's curculatory system, comprising: a first arm and a second arm hinge-joined to each other; said first arm having a first end and a second end; said second arm having a first end and a second end; handles provided at said first ends of said first and second arms; at least three similar working jaws, which can be brought together for a valve prosthesis to set thereon, and be brought apart for said valve prosthesis to hold thereto, thus giving said valve at least three points of bearing; said working jaws being articulated to said second end of said first arm and having vacant ends which, when brought apart, form a circle along their perimeter; said at least three working jaws, each of them being arranged at an angle of 90° to a longitudinal geometric axis of the holder; said working jaws being of a curved shape; a plate having a plurality of slots equal in number to that of said working jaws; said plate being secured at said second end of said second arm in such a manner that one of said working jaws is passed through each of said slots so that when said working jaws are being brought together or apart, they are free to traverse along said slots, and the edge of each of said slots slides along said curved working jaw passing through said slot.
