Abstract:
1. A restraining mechanism configured to prevent outward expansion of a plurality of support struts, the restraining mechanism comprising: an intravascular filtering device including the plurality of support struts and a filter attached to at least one of the plurality of struts; a ribbon having a proximal end, a distal end, and at least two tubular members configured to receive an actuating member; and an actuating member configured to slidably engage the at least two tubular members, the actuating member including a distal stopping feature configured such that the distal stopping feature cannot pass through at least one of the two tubular members; wherein the ribbon is adapted to wrap around the filtering device at least one revolution and applies a restraining force to the plurality of support struts to prevent the plurality of support struts from expanding outward; wherein the actuating member is configured to release the restraining force of the ribbon and allow the outward expansion of the plurality of support struts when the actuating member is moved in a proximal direction; and wherein the ribbon is non-removably coupled to the actuating member; wherein the ribbon has at least one tubular of the two members fixedly attached to each of the proximal end and the distal end of the ribbon.
