Assembly for crimping an implant frame
A recently filed patent (Publication Number: US20230293293A1) describes an apparatus for crimping a frame of an implant. The apparatus includes a crimping assembly consisting of a bath with one or more side-walls and a crimping mechanism. The crimping mechanism is attached to the bath in a way that the crimping aperture is located within the bath, below the side-wall height.
In one embodiment, the crimping mechanism has a first side and a second side, and the bath has an internal width that allows a human operator to place their hands on both sides of the crimping mechanism simultaneously. This design ensures ease of use and accessibility for the operator.
The patent also specifies that the internal width of the bath is 16-24 cm greater than the thickness of the crimping mechanism. This ensures that there is enough space within the bath to accommodate the crimping mechanism and allows for efficient crimping of the implant frame.
The patent further describes a system that includes the aforementioned apparatus and an implant. The frame of the implant is tubular and can be in a crimped or non-crimped state. In the crimped state, the radial diameter of the frame is smaller than in the non-crimped state. The implant can be a prosthetic heart valve or a vascular stent, indicating potential applications in the medical field.
Additionally, the patent discusses the working diameter of the crimping mechanism and the internal width of the bath. The internal width of the bath is greater than the working diameter, with the patent specifying that it is less than 5 cm greater, and in some embodiments, less than 2 cm or even 1-10 mm greater. This ensures a snug fit for the crimping mechanism within the bath, allowing for precise and controlled crimping of the implant frame.
Overall, this patent presents an apparatus and system for crimping an implant frame, particularly suited for prosthetic heart valves or vascular stents. The design allows for ease of use, precise crimping, and efficient operation.
