Abstract
The present invention provides, in certain aspects, devices and methods for plugging passageways and other open spaces in the body. In one embodiment, a plugging assembly comprises a first plug member and a second plug member, wherein the second plug member is configured to contact and move a portion of the first plug member in plugging a body passageway. These plug members may be formed with one or more of a variety of biocompatible materials including some that are naturally derived and some that are non-naturally derived. In another embodiment, such a plugging assembly is combined with a device that is suitable for delivering the assembly into a body passageway.
Claims27
A device for plugging a passageway in the body, comprising:
- a first plug member;
- and
- a removable second plug member positioned in the first plug member, the second plug member effective to force at least a segment of the first plug member to radially expand as the second plug member is being positioned in the first plug member.
An assembly for plugging a passageway in the body, comprising:
- a first plug member having a lumen;
- and
- a second plug member positionable in said lumen and effective as it is being positioned in said lumen to cause at least part of the first plug member to become outwardly displaced for plugging the body passageway.
A method for plugging a passageway in the body, comprising:
- providing a plugging assembly including a first plug member and a second plug member;
- delivering the first plug member and the second plug member to the body passageway;
- and
- causing relative movement between the first plug member and the second plug member, wherein contact between the first plug member and the second plug member outwardly displaces at least part of the first plug member for plugging the body passageway.
A method for plugging a passageway in the body, comprising:
- providing a plugging device delivery apparatus, the apparatus comprising:
- a delivery device having a lumen communicating with a distal end opening, the delivery device configured for passage through a body passageway;
- a first plug member received in the delivery device lumen;
- and
- a second plug member received in the delivery device lumen, the second plug member positionable in the first plug member and effective in the first plug member to outwardly displace at least part of the first plug member for plugging the body passageway;
- passing the delivery device through at least a segment of the body passageway;
- removing the first plug member from the delivery device lumen;
- removing the second plug member from the delivery device lumen;
- positioning the first plug member at a location in the body passageway;
- and
- causing relative movement between the first plug member and the second plug member, wherein contact between the first plug member and the second plug member outwardly displaces at least part of the first plug member for plugging the body passageway.
A method for plugging a passageway in the body, comprising:
- providing a plugging assembly, comprising:
- a first plug member having a lumen;
- and
- a second plug member;
- delivering the first plug member to the body passageway;
- and
- filling at least part of the first plug member lumen with the second plug member.
An assembly for plugging a passageway in the body, comprising:
- a first plug member having a cavity therein and positionable in a body passageway;
- and
- a second plug member comprised of a porous, collagen-containing matrix material and including a segment positionable in the cavity of the first plug member, the second plug member having a first condition suitable to deliver the segment to the first plug member cavity, and a second, expanded condition providing a more snug fit of the segment in the first plug member cavity relative to the first condition of the second plug member.
