摘要： Devices including a capsule having an interior and a clamp assembly including a plurality of clamps. Each clamp includes a first arm having a first free end and a second arm having a second free end. The device includes a clamp assembly including a compacted state in which the plurality of clamps are compressed within the capsule and a deployed state in which at least the free ends of the plurality of clamps are positioned outside of the interior of the capsule. The first free end is closer to the second free end in the compacted state as compared to the deployed state. The device can further include a push rod releasably secured to the clamp assembly and a delivery rod releasably secured to the capsule. Methods of using the devices are also disclosed.

摘要： A method include of delivering a heart valve prosthesis includes loading the heart valve prosthesis in a crimped configuration within a dilator shaft, tracking the dilator shaft within a vasculature of a patient to a desired site with the heart valve prosthesis loaded therewithin, advancing a delivery device through the dilator shaft to the distal end of the dilator shaft, advancing the delivery device through the heart valve prosthesis to load the heart valve prosthesis onto the delivery device, advancing the delivery device with the heart valve prosthesis mounted thereon past the distal end of the dilator shaft to a treatment site within the vasculature of the patient, and deploying the heart valve prosthesis from the delivery device at the treatment site.
