Claims25
An embolism filter disposed on a guidewire, said embolism filter having an actuatable stop configured to selectively stop the embolism filter from longitudinally moving along a guidewire, the filter comprising:
- a filter element secured to a sleeve slideably disposed about the guidewire;
- the actuatable stop disposed within an interior space of the sleeve;
- and
- a restrainer disposed in a radial space between the actuatable stop and the guidewire, wherein the stop is actuated through removal of the restrainer from the space or dissolution of the restrainer, so as to urge the actuatable stop against the guidewire to prevent movement of the filter element along the guidewire.
An embolism filter disposed on a guidewire, said embolism filter having an actuatable stop configured to selectively stop the embolism filter from longitudinally moving along a guidewire, the filter comprising:
- a filter element secured to a sleeve slideably disposed about the guidewire;
- the actuatable stop comprising at least one inflatable member secured within an interior space of the sleeve;
- and
- a passageway in fluid connection with the at least one inflatable member,
- wherein the at least one inflatable member is urged against the guidewire by applying a fluid pressure through the passageway.
An actuatable guidewire stop disposed on a guidewire, said guidewire stop adapted to selectively stop an intravascular device from longitudinally moving relative to a guidewire, comprising:
- a sleeve slideably disposed about the guidewire;
- the actuatable guidewire stop secured within an interior space of the sleeve;
- and
- a restrainer disposed between the actuatable stop and the guidewire,
- wherein displacement or dissolution of the restrainer urges the actuatable stop against the guidewire to prevent longitudinal movement of the sleeve along the guidewire.
