Abstract
A set of instruments for crimping a support structure of a heart valve having a first crown and a second crown. The set includes at least one instrument comprising a handle terminating at one end as a cylindrical body, the cylindrical body having a lateral surface provided with seats for receiving therein the front crown of the support structure. The set further includes a cap slidable on the cylindrical body to block the first crown there, and at least one crimping ring for crimping the second crown.
Claims15
A set of instruments for crimping a support structure of a heart valve comprising a first crown and a second crown, comprising:
- at least one instrument comprising a handle terminating at one end as a cylindrical body, the cylindrical body having a lateral surface and seats on the lateral surface for receiving therein the first crown of the support structure, and a cap slidable on the cylindrical body to block the first crown on the cylindrical body;
- and
- at least one crimping ring for crimping the second crown.
A procedure for crimping a support structure of a heart valve, the support structure having a first crown and a second crown, wherein the procedure comprises the steps of:
- i. crimping the first crown of the support structure to a first diameter of the first crown;
- ii. maintaining the first crown crimped at the first diameter of the first crown, crimping the second crown to a first diameter of the second crown;
- iii. maintaining the second crown crimped at the first diameter of the second crown, crimping the first crown to a second diameter of the first crown smaller than the first diameter of the first crown;
- and
- iv. maintaining the first crown crimped at the second diameter of the first crown, crimping the second crown at a second diameter of the second crown smaller than the first diameter of the second crown.
A crimper comprising at least a first plate and at least a second plate able to rotate with respect to each other about a common axis, a plurality of crimping structures in the form of wedges and received between the first plate and the second plate, the plurality of crimping structures being configured so as to collectively define a hole with a variable diameter in accordance with the mutual positioning of the crimping structures, the crimping structures further defining a pair of apertures.
