Abstract
An apparatus for crimping down a radially expandable stent to a pre-determined profile, the apparatus has at least one set of rollers, each set including a first roller having at least a first groove and a second roller also having at least a first groove, the first groove on the first roller having the same dimensions and corresponding in relative location along the roller with the first groove on the second roller. The first groove on the first roller is aligned with the corresponding first groove on the second roller so that the respective first grooves together define an aperture whereby on rotation of the rollers, a stent advanced toward the rollers is drawn into the aperture thereby crimping down the stent to the pre-determined diameter.
Claims11
An apparatus for crimping a stent, the apparatus comprising:
- A mounting block;
- A first pair of rollers comprising a first roller having a first groove and a second roller having a second groove, the first pair of rollers positioned on the mounting block such that the first groove is aligned with the second groove to form a first aperture for receiving a stent therethrough.
An apparatus of claim 1 and further comprising a n+1 pair of rollers having a n+1 pair of grooves, the n+1 pair of rollers positioned on the mounting block such that the n+1 pair of grooves are aligned to form a n+1 aperture for receiving the stent therethrough, the n+1 aperture smaller in diameter than the nth aperture.
An apparatus of claim 6 where the n+1 pair of rollers are mounted perpendicular to the nth pair of rollers.
An apparatus for crimping a stent, the apparatus comprising:
- A mounting block;
- A first pair of rollers comprising a first roller having a first groove and a second roller having a second groove, the first pair of rollers positioned on the mounting block for transverse rotation such that the first groove is aligned with the second groove to form a first aperture for receiving a stent therethrough, the first aperture has a substantially circular cross section and predetermined diameter.
An apparatus of claim where the third pair of rollers are mounted perpendicular to the second pair of rollers.
An apparatus of claim 8 further comprising a first pair of grooves defined by the first and second grooves and a second pair of rollers having a pair of grooves, the second pair of rollers positioned on the mounting block for transverse rotation such that the pair of grooves are aligned to form a second aperture for receiving the stent therethrough, the second aperture having a substantially circular cross section and a predetermined diameter smaller than predetermined aperture of the first pair of rollers.
