Abstract
An implantable and removable filter that may be implanted in and/or removed from a body lumen, such as the Vena Cava. The filter including tissue anchors on expandable anchoring legs, which can be selectively moved between a non-anchoring or pre-deployed configuration into an anchoring or deployed configuration by obturators that are movable inside the anchoring legs.
Claims20
An implantable and retrievable filter for use in a body lumen, the filter comprising:
- one or more first anchoring legs having a pre-deployed, non-anchoring configuration, and a deployed, anchoring configuration, wherein each of the one or more first anchoring legs in the deployed, anchoring configuration has a first anchor sized and configured to anchor the filter within the body lumen;
- one or more first obturators movable inside the one or more first anchoring legs from a first position to a second position;
- and
- wherein:
- the one or more first anchoring legs are in the pre-deployed non-anchoring configuration when the one or more first obturators are in the first position;
- and
- the one or more first anchoring legs are in the deployed, anchoring configuration when the one or more first obturators are in the second position.
4 more elements
A filtering system for deployment in a body lumen, the system comprising:
- a filter including:
- at least one anchoring leg reconfigurable between a pre-deployed, non-anchoring configuration, and a deployed, anchoring configuration, the at least one anchoring leg forming one or more anchors sized and configured to anchor the filter within the body lumen;
- at least one obturator, wherein the at least one anchoring leg and the at least one obturator are movable relative to each other between a first position and a second position, in the first position the at least one anchoring leg being in the pre-deployed, non-anchoring configuration, and in the second position, the at least one anchoring leg being in the deployed, anchoring configuration;
- and
- a catheter including:
- an outer sheath sized and configured to house the filter therein;
- and
- one or more inner members coupled to one or more of the at least one anchoring leg and the at least one obturator, the one or more inner members being movable to position the at least one anchoring leg and the at least one obturator at one or more of the first position and the second position.
5 more elements
A method of removably implanting a filter in a body lumen, the method comprising:
- positioning the filter inside the body lumen;
- expanding one or more anchoring legs into a partially-deployed configuration, the one or more anchoring legs being positioned near a wall of the body lumen in the partially-deployed configuration;
- moving one or more of the one or more anchoring legs and one or more obturators from a first position to a second position, the one or more obturators being movable inside the one or more anchoring legs;
- and
- reconfiguring the one or more anchoring legs into the deployed configuration, each of the one or more anchoring legs forming one or more anchors that engage the anchoring legs with a wall of the body lumen.
