Abstract: A delivery device for percutaneously delivering a stented prosthetic heart valve includes a capsule assembly, a handle, and an outer stability shaft. The capsule assembly includes a capsule and a proximal shaft coupled to the capsule. The capsule includes an expanded configuration wherein the capsule has a first outer diameter, and a collapsed configuration wherein the capsule has a second outer diameter smaller than the first outer diameter. The outer stability shaft defines a lumen and is coupled to the handle and configured to receive the proximal shaft within the lumen of the outer stability shaft. The outer stability shaft has an inner diameter, wherein the first outer diameter of the capsule is greater than the inner diameter of the outer stability shaft and the second outer diameter of the capsule is smaller than the inner diameter of the outer stability shaft.

Abstract: An embolic protection device includes a shaft, a first magnet fixedly coupled to a distal portion of the shaft, a second magnet slidingly coupled to the shaft proximal to the first magnet, and a filter including a distal portion coupled to the first magnet and a proximal portion coupled to the second magnet. The first and second magnets are magnetically attracted to each other such that in a radially compressed configuration of the filter, the second magnet is spaced from the first magnet a first distance, and in a radially expanded configuration of the filter, the second magnet slides towards the first magnet such that the second magnet is spaced a second distance from the first magnet, wherein the second distance is smaller than the first distance.
