摘要： A medical device shaft for connection with a handle and for insertion within a body includes an elongated, deflectable shaft having a proximal shaft portion, an intermediate shaft portion, and a distal shaft portion. The elongated, deflectable shaft includes a transition in stiffness from the proximal shaft portion to the distal shaft portion. In a preferred implementation, the shaft includes a plurality of slits that extend perpendicular to a longitudinal axis of the shaft. Varying at least one of the number of slits, the location of slits, the frequency of slits, the orientation of the slits, the size of the slits, and the depth of the slits varies the transition of stiffness.

摘要： Devices for loading a collapsible implant onto a delivery catheter. In one aspect, a loading device comprises an outer tubular structure and an inner tubular structure. The outer tubular structure comprises a narrowing passage configured to receive a catheter at one end and a collapsible implant at another end. The inner tubular structure is configured to move slidably and co-axially within the outer tubular structure. The inner tubular structure comprises a carrier pin configured to move within the narrowing passage as the inner tubular structure slides into the outer tubular structure. The sliding of the inner tubular structure into the outer tubular structure causes an implant mounted on the carrier pin to collapse as the implant moves through the narrowing passage and into the distal end of a catheter. In an optional aspect, the outer tubular structure further comprises a grasper to stabilize the catheter for receipt of the collapsible implant, and the internal diameter of the inner tubular structure varies to cause the grasper to first contract and stabilize the catheter, and then expand and release the catheter, as the grasper moves into the inner tubular structure.

摘要： This is an assembly for controllably delivering vaso-occlusive devices to a selected site within the vasculature or other lumen of the human body by the use of a catheter. In particular, the device includes a holding member which is at least generally tubular and has an opening through the tubular wall. The vaso-occlusive device to be delivered has on one end a mating member which may be at least partially pressed into the opening in the wall of the holding member. The mating member attached to the vaso-occlusive member is held in the opening with an interference wire. The interference wire is axially movable within the holding member and has a diameter sufficient to hold the mating member within the wall opening. Upon proximal movement of the interference wire, the mating member becomes free to leave the holding member. The interference wire may be tapered or not. The vaso-occlusive member may be a helically wound coil or a braid or other appropriate form.
