Medical devices, apparatuses, systems, and methods

摘要

Medical devices having a platform and an arm movable between a collapsed position and an expanded position. In some embodiments, the platform comprises at least one of a magnetically-attractive material and a material capable of being magnetically-charged. Methods of use.

主权项

1. A medical device comprising:
a platform; an arm having a hub that is pivotally coupled to the platform such that the arm is rotatable at least 90 degrees around a rotational axis between a collapsed position and an expanded position; a threaded member rotatably coupled to the platform; a shuttle coupled to the threaded member; and a shuttle arm having a first end coupled to the shuttle and a second end coupled to the hub of the arm; where the medical device is configured such that:
a tool can be coupled to the threaded member such that the tool can be rotated to rotate the threaded member; andif the threaded member is rotated in a first rotational direction when the arm is in the collapsed position, then the shuttle will travel in a substantially linear first direction to cause the arm to rotate from the collapsed position toward the expanded position.
