摘要： PROBLEM TO BE SOLVED: To uniformly crimp a stent by positioning the stent and a catheter inside the cavity of a stent crimping tool, clogging a segmented jaw on the stent which is fitted to a balloon part and crimping the catheter by the stent. SOLUTION: A stent 10 is fitted to a dilation balloon 14 at the far end of a supply catheter 11 and then, it is set inside the cavity 58 of a segment jaw 30 to be opened in a flared shape in a stent pressurizing tool. Thus, the balloon 14 where the uncrimped stent 10 is fitted in a right position is positioned inside the collet end part of a cylindrical main body 25. In this state, a cylindrical collar 34 is twisted and is advanced in the arrow 54 direction along the cylindrical main body 25. Thus, a front end part 36 advances and is engaged with the segmented jaw 30. As the result, the segmented jaw 30 is clogged and the stent 10 is uniformly crimped onto the balloon 14.

摘要： PROBLEM TO BE SOLVED: To keep fitting till a stent transplant and to enable uniform and firm crimping by combining a plurality of cams and a base groove with a plurality of parallel tangents, forming an axial direction space, inserting a stent to the space and executing crimping by the rotation of the cams. SOLUTION: A stent crimping tool 22 is constituted by arranging first and second horizontal cams 24 and 26 and a third vertical cam 28 with basically the same structure so that they are super imposed on a base 30. The first horizontal cam 24, for example, is provided with a semicircular edge 32 having the groove of 1/4 circular contour to be engaged with the outer diameter of the stent. The groove 72 which coincides with the tangent of the cams 24, 26 and 28 is formed in the base 30. The first and the second cams 24 and 26 impart pressure to the stent at the positions of about 0 deg. and 180 deg. and the third cam 28 and the groove 72 impart pressure to the stent at the positions of about 90 deg. and 270 deg. so that crimping is uniformly executed in a balloon. Uniform crimping is secured by the synchronizing rotation of the respective cams 24, 26 and 28.

摘要： PROBLEM TO BE SOLVED: To crimp effectively a stent by providing a loop portion that supports the stent and can be compressed radially inwardly and can be loosened in a crimping device intended for attaching an intravascular stent to the distal end of a balloon catheter assembly in a state of covering. SOLUTION: In order to crimp an intravascular stent 5 to a shrived balloon portion adjacent to the distal end 7 of a balloon catheter assembly 8, a U-shaped receiving member 22 and an engaging member 24 stored in the interior thereof are provided. A crimping member 32 is fastened to the projection 28 of the internal end of the engaging member 24 provided with a handle portion 26 at the external end. The crimping member 32 has a compressible loop portion 42 at least in one direction of contraction, one end 36 of which is fixed to the receiving member 22, and the other end 34 being fixed to the projection 28. Therefore, by the sliding of the engaging member 24, the compressible loop portion 42 contracts, crimping the stent 5 to the balloon portion 6.

摘要： PROBLEM TO BE SOLVED: To provide a crimp tool capable of securing a small outside diameter of a stent on the balloon part of a catheter and maintaining a state of reliably installing the stent on a balloon. SOLUTION: A stent crimp tool to reliably/uniformly crimp a stent 10 on a catheter 11, is composed of a base having two vertical support bodies spaced mutually and a coil-shaped tension spring having one end installed on a shaft and the other end installed on one vertical support body. When the stent 10 is loaded on the balloon 14 part of the catheter 11 and a stent/catheter assembly is also inserted into an axial directional space in the coil-shaped spring, a user can uniformly crimp the stent 10 on a balloon 14 by contracting the coil-shaped spring by twisting the coil-shaped spring by rotating the shaft.

摘要： PROBLEM TO BE SOLVED: To provide a crimping tool to crimp stent at the balloon part of a catheter. SOLUTION: A stent crimping tool consists of a housing having a near part coupled to a remote part. A cylindrical cavity 40 having a tapered-off tip 42 is formed at the near part. A cylinder collar 32 fitted in the end of the tapered- off part is fixed in a cavity. A tooth has a rounded edge part 62 sliding in the slot of a collar. A hollow core and a screw feed 28 are screwed in the remote part. A balloon catheter is extended through the passage of the near part and the collar and the stent 10 positioned in the hollow core of a screw and not crimped is charged therein. The remote portion of a housing is rotated, a screw and a tooth 30 are advanced toward a cavity having an inclination wall and the tooth is radially internally converged by the inclination wall. The rounded edge part of the tooth causes the stent 10 to be crimped by the balloon catheter.

摘要： PROBLEM TO BE SOLVED: To crimp a stent by providing a cylindrical loop portion that can be expanded and contracted elastically in the radial direction, expanding the loop portion by moving down pivoting arm portions, and tying the stent to a balloon catheter assembly in the loop portion. SOLUTION: A crimping device 10 that crimps a stent A in a blood vessel to the contracted balloon portion B of a balloon catheter assembly D has a base portion 14 having a pair of V slits 26, 28 to which a loop portion 12 whose circumferential length can be varied, is attached. The existence of the V slits 26, 28 helps pivoting arm portions 18, 20 to be pivoted to the base portion 14 rockably downward. The loop portion 12 that is made of a flexible and strong material and has multiple straps 40 is fixed to the pivoting arm portions 18, 20 by crimping portions 38, and the stent A is crimped to the balloon portion B by the rocking motion of the pivoting arm portions 18, 20 in the loop portion 12.

摘要： A pivotally-engageable device for enabling uniform and tight crimping of an intravascular stent onto a balloon catheter assembly. The stent crimping device includes at least one releasable loop portion that enables the stent and catheter assembly to be supported therein. The ends of the loop portion are moved in opposite directions thereby reducing the size of loop radially inwardly to uniformly and tightly crimp the stent onto the balloon catheter assembly.

摘要： A tool and method for enabling substantially uniform and tight crimping of an intravascular stent onto a balloon catheter assembly. The crimping tool is constructed from a rigid cylindrical chassis sealed at both ends, having a hollow interior containing an elastic tube that partially occupies the interior. A piston abuts the elastic tube and forms a hermetically sealed chamber behind the piston and a closed end ofthe chassis. A port connected to an indeflator and positioned on the chassis provides an inlet into and out of the chamber. A stent that is loaded onto the balloon portion of the catheter is inserted through a central opening in another end of the chassis to position the stent catheter assembly within the axial space inside the elastic tube. The indeflator injects a fluid into the chamber thereby increasing its pressure which in turn displaces the piston into the elastic tube compressing the tube longitudinally. The elastic tube decreases in length and expands in thickness radially to crimp the stent onto the balloon catheter. Once pressure is relieved from the chamber, the piston moves away from the elastic tube, which restores to its original shape. The crimped stent and catheter can then be withdrawn. The piston may be driven by a power screw in place of fluid pressure.
