Abstract
A combined multi-lumen sheath with a wire body and a filter. The filter may be removably coupled to the multi-lumen sheath within a filter capsule for temporary placement and retrieval.
Claims18
A medical device, comprising:
- a. a multi-lumen sheath having a central lumen including a wire body longitudinally disposed within the central lumen;
- and
- b. a filter capsule operably associated with a distal end of the multi-lumen sheath and longitudinally translatable within one lumen of the multi-lumen sheath;
- c. a filter member having a first end coupled to the wire body, the filter member having a diametrically enlarged state and a diametrically collapsed state, wherein the diametrically collapsed state is coaxially disposed with the filter capsule upon movement of the wire body along a longitudinal axis of the multi-lumen sheath.
1 more element
A vena cava filter catheter system, comprising:
- a. a multi-lumen sheath having a central lumen and a sheath wall surrounding the central lumen, a first port associated with a first lumen within the sheath wall of the multi-lumen sheath;
- a second port associated with a second lumen within the sheath wall of the multi-lumen sheath;
- and a third port associated with a third lumen within the sheath wall of the multi-lumen sheath;
- b. at least one wire longitudinally disposed within the first lumen, the second lumen, and the third lumen;
- c. a filter member operably associated with the distal ends of the at least one wires longitudinally disposed within the first lumen, the second lumen, and third lumen, wherein the at least one wires allow expansion of the filter member to a diametrically enlarged state from a diametrically collapsed state.
2 more elements
A vena cava filter catheter system comprising:
- a. a multi-lumen sheath having a central lumen and a thickness surrounding the central lumen, at least two secondary lumens longitudinally disposed within the thickness of the multi-lumen sheath, each of the at least two secondary lumens having an opening at a distal end of the secondary lumen;
- b. at least one wire disposed within at least one of the at least two secondary lumens and extending both proximally and distally through the at least one of the at least two secondary lumens;
- c. a filter member operably associated with a distal end of the at least one wire, wherein longitudinal translation of the at least one wire within the at least one of the at least two secondary lumens causes expansion of the filter member to a diametrically enlarged state from a diametrically collapsed state.
