    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: A method and system for catheter-based delivery of implants in the body. Implants can include stents, plugs, coils, baskets, filters, valves, grafts, prosthesis', drugs, drug reservoirs, biologics, or pumps. The catheter system comprises a uniquely configured grasper mechanism that allows holding the implant during the unsheathing delivery step prior to full release. With this delivery system, the implant can be unsheathed, positioned, and the position can be evaluated prior to releasing the implant from the catheter. Upon evaluation of the position of the implant, if it is found to be inaccurately placed, then removal of the implant can be done easily and without a device exchange. If the implant is found to be positioned correctly, the grasper mechanism can be actuated to release the implant from the catheter.
