Device for compressing a stent
First Claim
1. A device for compressing a stent, comprising:
- a compressing mechanism configured to at least partially accommodate a stent, the compressing mechanism includingat least one clamping element configured to selectively exert a compressive force in a radial direction on the stent to reduce the cross-sectional dimension of at least a portion of the stent; and
a housing including a first housing section and a second housing section, wherein an inner circumferential surface of the first housing section includes a plurality of slits, the inner circumferential surface of the first housing being tapered towards the second housing section; and
a manipulating mechanism configured to manipulate the at least one clamping element, the manipulating mechanism being moveable relative to the compressing mechanism for affecting movement of the at least one clamping element in the radial direction.

Abstract
The present disclosure relates to a device for compressing a stent or a stent with a prosthetic heart valve affixed thereto, as well as a method for loading a stent into a medical delivery system. The device may comprise a compressing mechanism designed so as to exert a compressive force in radial direction on at least parts of a stent accommodated within the compressing mechanism such that the cross-section of the stent is reduced to a predefinable value at least at certain areas. The device may further comprise a manipulating mechanism moveable relative to the compressing mechanism for moving at least one clamping means in the radial direction in order to adjust the internal cross-sectional diameter of the compressing mechanism.

19. A device for compressing a stent, comprising:
-
a compressing mechanism configured to at least partially accommodate a stent, the compressing mechanism including at least one clamping element configured to selectively exert a compressive force in a radial direction on the stent to reduce the cross-sectional dimension of at least a portion of the stent, the at least one clamping element including a plurality of jaws circumferentially arranged such that respective radial inward surfaces of the jaws define a cavity at least partially surrounding the stent; and a manipulating mechanism configured to manipulate the at least one clamping element, the manipulating mechanism being moveable relative to the compressing mechanism for affecting movement of the at least one clamping element in the radial direction, wherein an inner surface of the manipulating mechanism includes a plurality of grooves, each groove extending in a longitudinal direction of the manipulating mechanism and configured to receive a respective head portion of one of the jaws.

20. A device for compressing a stent, comprising:
-
a compressing mechanism having a longitudinal axis, a housing, and a plurality of jaws; a plurality of slits disposed in a first section of the housing, the plurality of slits being arranged circumferentially about the longitudinal axis of the compressing mechanism, the plurality of jaws respectively disposed within the plurality of slits; a plurality of rails disposed in a second section of the housing, the plurality of rails being arranged circumferentially about the longitudinal axis of the compressing mechanism; and a manipulating mechanism at least partially surrounding the housing and engaging the plurality of jaws; wherein the manipulating mechanism is configured to move longitudinally relative to the housing and affect longitudinal movement of the plurality of jaws from the first section of the housing to the second section of the housing; and wherein the plurality of jaws are configured to respectively engage the plurality of rails during movement from the first section of the housing to the second section of the housing and move radially inward toward the longitudinal axis of the compressing mechanism thereby reducing the cross sectional size of at least a portion of a stent accommodated radially within the plurality of jaws.
