Abstract: A medical device controller is provided that avoids unintended user inputs and unwanted medical device operation(s). A controller sends display commands to a graphical user interface (GUI) display to generate a first screen having a swipe field with no moving icons that prompts a user to initiate a designated operation by the medical device. When a valid swipe gesture is inputted, the controller generates a second screen with confirm button that requires a valid user press before the controller undertakes the designated operation, the controller generating and sending a command for the designated operation to the medical device when the controller determines that a valid user press has been inputted to the confirm button. The controller also sends commands to generate a status screen that transitions a rotating progress ring symbol and level indicator in accordance with a selected event to clearly indicate the status of medical device operations.

Abstract: A retrievable medical filter which can be placed in a blood vessel or other body passage. The filter has improved structural features for enhancing its filter effectiveness and to facilitate its retrieval from the body passage. The filter has a longitudinal spine with struts extending from each longitudinal to form filter baskets. The ends of the spine to which the struts are attached may be rings with serpentine cuts in the rings to make them expandable. The struts can extend circumferentially as well as radially outwardly to provide a structure which can be radially compressed without bending the struts in a tight radius.

Abstract: A medical filter intended for placement inside a tubular body passage such as a blood vessel of a patient, the medical filter having an end member at one end of the longitudinal axis of the filter. The end member supports a retrieval element and a plurality of struts defining a first filter cone proximate to the end member and a second filter cone distal from the end member.
