Claims
- 1. A filter device for capturing embolic material in a blood vessel comprising:
a guide wire having a proximal end and a distal end; an expandable frame of frame members having a radiopaque coating and having a closed, radially compact form and an open, radially expanded form and a fore end and an aft end, said aft end coupled to said distal end of said guide wire, said frame of frame members in said radially expanded form forming a pair of facing generally frustoconical frame structures; a filter material attached to one of said pair of frustoconical frame structures; and an actuator sleeve adapted to run over said guide wire, said actuator sleeve enabling longitudinal compression of said expandable frame and frame members thereby causing said frame to radially expand and deploy said filter material.
- 2. A filter device as claimed in claim 1 wherein said radiopaque coating is one of gold or platinum.
- 3. A filter device for capturing embolic material in a blood vessel comprising:
a guide wire having a proximal end and a distal end; an expandable frame of frame members having a closed, radially compact form and an open, radially expanded form and a fore end and an aft end, said aft end coupled to said distal end of said guide wire, said frame of frame members in said radially expanded form forming a pair of facing generally frustoconical frame structures; a filter material attached to one of said pair of frustoconical frame structures; and an actuator sleeve adapted to run over said guide wire, said actuator sleeve having a flexible distal end coupled to said aft end of said expandable frame, enabling longitudinal compression of said expandable frame and frame members thereby causing said frame to radially expand and deploy said filter material.
- 4. A filter device as claimed in claim 3 wherein said flexible actuator end piece is a coiled material.
- 5. A filter device as claimed in claim 4 wherein said flexible actuator end piece permits flexation of the frame relative to the guide wire in excess of 90 degrees.
- 6. A controllable deployment system for a radially expandable frame utilized during catheterization comprising:
a guide wire having a proximal end and a distal end; a radially expandable radiopaque frame having a closed, radially compact, elongated form and an open, radially expanded, longitudinally foreshortened form, said radiopaque frame having distal and proximal frame ends; said guide wire extending through said expandable radiopaque frame; an elongated actuation sleeve having a distal end, a proximal end, and a lumen through which passes said guide wire, said distal sleeve end coupled to said proximal frame end; a locking mechanism at a proximal end of said actuable sleeve locking during one of radial expansion or radial closure of said expandable frame.
- 7. A system as claimed in claim 6 wherein said radiopaque frame is coated with one of gold or platinum.
- 8. A controllable deployment system for a radially expandable frame utilized during catheterization comprising:
a guide wire having a proximal end and a distal end; a radially expandable frame having a closed, radially compact, elongated form and an open, radially expanded, longitudinally foreshortened form, said frame having distal and proximal frame ends; said guide wire extending through said expandable frame; an elongated actuation sleeve having a distal flexible end, a proximal end, and a lumen through which passes said guide wire, said distal flexible end coupled to said proximal frame end; a locking mechanism at a proximal end of said actuation sleeve locking during one of radial expansion or radial closure of said expandable frame.
- 9. A system as claimed in claim 8 wherein said flexible actuation sleeve end piece is a coiled material.
- 10. A system as claimed in claim 9 wherein said actuation sleeve end piece permits flexation of the frame relative to the guide wire in excess of 90 degrees.
- 11. A system as claimed in claim 8 wherein said frame is radiopaque a radially inboard locking surface has an interference fit with a radially outboard locking surface.
- 12. A filter device for capturing embolic material in a blood vessel comprising:
a guide wire having a proximal end and a distal end; an expandable frame of frame members having a radiopaque coating and having a closed, radially compact form and an open, radially expanded form and a fore end and an aft end, said aft end coupled to said distal end of said guide wire, said frame of frame members in said radially expanded form forming a pair of facing generally frustoconical frame structures; a filter material attached to one of said pair of frustoconical frame structures; and an actuator sleeve adapted to run over said guide wire, said actuator sleeve enabling longitudinal compression of said expandable frame and frame members thereby causing said frame to radially expand and deploy said filter material, and said actuator sleeve including a latch for placing said expandable frame in one of a compressed state and a filter deployed state.
