Patent ID: 8062327

Claim:
A blood filter delivery system for a blood filter unit, comprising: an introducer having a coupling port connected to an elongated generally tubular member; a storage member coupled to the coupling port of the introducer and a Y-adaptor; and a pusher assembly having a distal end disposed in the storage member and a proximal end extending out of the Y-adapter, the pusher assembly including: a handle disposed along a longitudinal axis of the pusher assembly proximate the proximal end; a pusher pad disposed along the longitudinal axis of the pusher assembly proximate the distal end; an elongated member between the handle and the pusher pad, the elongated member having a flexible section with a distal end directly in contact with and continuous with a proximal end of the pusher pad, the flexible section compressed along the longitudinal axis in a predeployed configuration to provide a spring force for filter deployment; and a spline member disposed on the pusher assembly along the longitudinal axis between the handle and the pusher, the spline member having a first boss portion and a second boss portion spaced apart along the longitudinal axis to provide a gap therebetween, the first boss portion including a plurality of longitudinal grooves; and a blood filter having a plurality of anchor members disposed about the longitudinal axis, each of the anchor members having: a portion disposed in each of the plurality of longitudinal grooves, respectively; and a hook disposed in the gap.
