A stent crimping assembly is provided for crimping a stent from a first diameter to a reduced second diameter. The crimping assembly includes a plurality of movable wedges disposed about a rotational axis to form a wedge assembly. Each wedge includes a respective first side and a second side converging to form a tip portion. The tip portions are arranged to collectively form an iris about the rotational axis thereof. The iris defines a crimp aperture about which the movable wedges are disposed. A control unit is electronically programmed to control the mechanical components. A method of calibrating the control unit includes inserting a quill of known diameter into the iris and reducing the diameter of the iris onto the quill.

Stent crimping system and method

A stent crimping assembly is provided for crimping a stent from a first diameter to a reduced second diameter. The crimping assembly includes a plurality of movable wedges disposed about a rotational axis to form a wedge assembly. Each wedge includes a respective first side and a second side converging to form a tip portion. The tip portions are arranged to collectively form an iris about the rotational axis thereof. The iris defining a crimp aperture about which the movable wedges are disposed. Each wedge is associated with a stationary structure and an rotational actuation unit such that during rotation of the actuation unit about the rotational axis, the iris is caused to rotate about the rotational axis, relative the stationary structure, for inward movement of the wedges to decrease the size of the aperture and outward movement of the wedges to increase the size of the aperture.

A stent crimping apparatus is provided which includes a crimping assembly adapted to crimp the stent, a clamp assembly configured to secure the medical device; and a control unit configured to control the movement of the crimp assembly. The clamp assembly includes a lower clamp device defining a seating groove formed and dimensioned to seat a portion of the medical device therein, and a retaining assembly having an elastomeric member. This elastomeric member defines a contacting groove oriented in an opposed manner proximate to at least a portion of the seating groove. The clamp assembly further includes an actuation mechanism associated with the retaining assembly and the lower clamp device such that operation thereof causes the retaining assembly to move between an opened condition and a closed condition. In the opened condition, the medical device can be positioned between the lower clamp device and the retaining assembly, and in the closed condition, retaining the medical device between the contacting groove of the elastomeric member and the seating groove of the lower clamp device.

Medical device delivery handle

A medical device for vessel occlusion, the medical device including an elongated body having a distal end portion, a proximal end portion, and a lumen disposed therethrough, an balloon disposed at the distal end portion of the elongated body, the balloon in fluid communication with the lumen. An opening defined at the proximal end portion of the elongated body, the opening being in fluid communication with the balloon via the lumen, and a valve body moveably disposed at the proximal end portion of the elongated body, the valve body movable between a closed position and an open position, the valve body configured to engage a surface of the elongated body, distal to the opening, to seal the opening when the valve body is in the closed position.
