Estimating the term…
A device and method of radially collapsing a medical device is disclosed. The device is in the form of an improved crimper which is capable of crimping a medical device. The crimper includes without limitation one or more of, a base plate, a stopper, two side plates, two housing plates with a handle, a plurality of jaws, two guide plates, at least one gear ring and a plurality of gear pins. The jaws, when assembled, collectively form an iris opening. The assembly of the crimper has a central opening through which the iris opening can be accessed. The device to be crimped is introduced in the central opening and held within the iris opening. The crimping is achieved by reducing the size of the iris opening (by moving the jaws simultaneously with respect to each other in synchronized manner) which in turn reduces the diameter of the prosthetic device.
A crimping device (100) for crimping a prosthetic device, the crimping device (100) comprising:
The crimping device (100) as claimed in any of the above claims, wherein the crimping device (100) comprises two side plates (105, 105′), each side plate (105, 105′) coupled with a corresponding housing plate (107, 107′) such that the two housing plates (107, 107′) are free to rotate relative to the side plates (105, 105′).
The crimping device (100) as claimed in any of the above claims, wherein the crimping device (100) comprises two guide plates (113, 113′) forming the guiding housing, each guide plate (113, 113′) comprising a central guide opening (113b) and a plurality of linear guides (113a) extending away from a central portion of the guide plate (113, 113′) in a radial direction;
The crimping device (100) as claimed in any of the above claims, wherein the head portion (117a) of each gear pin (117) has a diameter that is larger than a diameter of the pin portion (117b) of the gear pin (117).
The crimping device (100) as claimed in any of the above claims, wherein the crimping device (100) comprises one or more stoppers (103) configured to restrict the downward movement of the handle (109) to prevent the size of the iris opening (111a) from reducing further.
The crimping device (100) as claimed in any of the above claims, wherein the prosthetic device is one of a balloon-expandable prosthetic device or a self-expandable prosthetic device.
The crimping device (100) as claimed in any of the above claims, wherein the prosthetic device is one of a vascular stent or a trans-catheter prosthetic heart valve.
