Abstract
A vascular lining removal assembly comprises a plurality of slats, each having inner and outer surfaces, configured to pass along a vascular cleavage plane to removingly engage a length of vascular lining. In some embodiments the assembly may also include means for engaging the length of vascular lining to aid removal of the length of vascular lining. The inner surface of at least one of the slats may comprise an inwardly opening passageway to permit direct access to the length of vascular lining by a tool.
Claims47
A vascular lining removal assembly comprising:
- a plurality of slats, each having inner and outer surfaces, configured to pass along a vascular cleavage plane to removingly engage a length of vascular lining.
A vascular lining removal element comprising:
- a slat, having inner and outer surfaces, configured to pass along a vascular cleavage plane to removingly engage a length of vascular lining;
- and
- the slat having a distal portion having an average thickness T , an average width W and a length L, with W being at least 3 times T and L being at least 80 times W.
A method for removing a length of vascular lining from a blood vessel comprising:
- positioning a plurality of slats, each having inner and outer surfaces, along a cleavage plane of a blood vessel;
- removingly engaging a length of vascular lining by the slats;
- and
- removing the slats and a removed length of vascular lining therewith from the remainder of the blood vessel, the removed a length of vascular lining having a length RL.
A vascular lining removal assembly comprising:
- a plurality of slats, each having inner and outer surfaces, configured to pass along a vascular cleavage plane to removingly engage a length of vascular lining;
- and
- the inner surface of at least one of the slats comprising a passageway extending along at least a portion of the inner surface, at least a portion of the passageway opening inwardly to permit direct access to the length of vascular lining by a tool.
A vascular lining treatment assembly comprising:
- a slat, having inner and outer surfaces, configured to pass along a vascular cleavage plane to engage a length of vascular lining;
- the inner surface of the slat comprising a passageway extending along at least a portion of the inner surface, at least a portion of the passageway opening inwardly to permit direct access to the length of vascular lining;
- and
- a tool engaging and passing along the passageway of the slat to permit engagement of the length of vascular lining by the tool.
A vascular lining removal element comprising:
- a slat, having inner and outer surfaces, configured to pass along a vascular cleavage plane to removingly engage a length of vascular lining;
- the inner surface comprising a passageway extending along at least a substantial portion of the inner surface, at least a portion of the passageway opening inwardly to permit direct access to the length of vascular lining by a tool;
- and
- the slat having a distal portion having an average thickness T , an average width W and a length L, with W being at least 3 times T and L being at least 80 times W.
A method for removing a length of vascular lining from a blood vessel comprising:
- positioning a plurality of slats, each having inner and outer surfaces, along a cleavage plane of a blood vessel, the inner surface comprising a tool passageway extending along at least a portion of the inner surface, at least a portion of the tool passageway opening inwardly to permit direct access to a length of vascular lining by a tool;
- engaging the length of vascular lining through at least one tool passageway by a tool;
- removingly engaging the length of vascular lining by the slats;
- removing the length of vascular lining therewith from the remainder of the blood vessel;
- and
- removing the tool from the blood vessel;
- and
- removing the slats from the blood vessel.
