Abstract: An alignment tool includes a body and a plurality of securement arms extending from the body, each of the plurality of securement arms adapted to releasably secure the alignment tool relative to a loader. The alignment tool includes a plurality of alignment arms extending from the body, each of the plurality of alignment arms including a first end having an alignment slot and an opposing second end including a handle portion, the plurality of alignment arms movable between a closed configuration defining a minimum distance between the first end of each of the plurality of alignment arms and an open configuration defining a maximum distance between the first end of each of the plurality of alignment arms. The plurality of alignment arms are biased into the closed configuration.

Abstract: A device for radially compressing a stent may include a housing including a central opening and a first iris positioned adjacent the housing. The first iris includes a first circumferential ring and a first plurality of arms extending radially inward from the first circumferential ring to define a first central opening. The device may include a second iris axially offset from the first iris and including a second circumferential ring and a second plurality of arms extending radially inward from the second circumferential ring to define a second central opening. Rotation of the circumferential ring(s) relative to the housing changes a size of their respective central opening(s). The plurality of arms may shift between a first configuration and a second configuration via rotation of the circumferential ring(s) relative to the housing.

Abstract: A device for compressing a stent may include a housing extending along a central longitudinal axis, a first threaded member and a second threaded member, a first iris and a second iris, and a compressor element disposed between the second iris and the second threaded member. The first iris includes a first ring extending transverse to the axis and a first plurality of arms extending from the first ring parallel to the axis. The first plurality of arms defines a first central opening and rotation of the first threaded member changes a size of the first central opening. The second iris includes a second ring extending transverse to the axis and a second plurality of arms extending from the second ring parallel to the axis. The second plurality of arms defines a second central opening and rotation of the second threaded member changes a size of the second central opening.

Abstract: An alignment tool for loading a stent includes a plurality of arms each having a shaft with an engagement region moveable between a first, angled configuration relative to the shaft, and a second, straight configuration, with each engagement region having an inner surface shaped to mate with a stent holder. The alignment tool further includes a lock ring having a lumen configured to receive the plurality of arms, with the lock ring configured to slide over the arms between a first retracted position in which the engagement region of each arm is exposed and allowed to bias into the angled configuration, and a second locked position in which the lock ring extends over at least a portion of the engagement regions and compresses the engagement regions into the straight configuration. The alignment tool may also include a spring configured to bias the lock ring in the locked position.

Abstract: Example medical device loading devices are disclosed. An example loading device for a stent-valve includes an elongated body having a proximal end region, a distal end region and a lumen extending therein. The loading device also includes a collar coupled to the distal end region of the body, the collar including first end region, a second end region and a lumen extending therein. Further, the loading device includes a first compression assembly coupled to the collar, wherein the first compression assembly is configured to shift between a first position a second position. The loading device also includes a second compression assembly coupled to the collar, wherein the second compression assembly is configured to shift between a third position and a fourth position.
