Apparatus and methods for occluding an anatomical structure
Apparatus and methods are disclosed for occluding an anatomical structure including an occlusion apparatus having first and second beams and at least one connector for connecting the respective ends of the beams together. The occlusion apparatus may be adapted for use in a deployment device having a pair of jaws and optionally having a respective pair of shuttle bodies for releasably connecting an occlusion apparatus to the jaws while in an open position and for releasing the occlusion device from the jaws while in a closed position. A system for occluding an anatomical structure is also disclosed that includes an occlusion apparatus and a deployment device for holding the occlusion apparatus in an open position for locating the occlusion device adjacent the anatomical structure to be occluded and then moving the occlusion apparatus to a closed position and locking the occlusion apparatus in the closed position.
1. An apparatus for occluding an anatomical structure comprising:
a first beam having first and second ends, where at least a portion of the beam is axially and longitudinally hollowed to receive a line;
a second beam having first and second ends, where at least a portion of the beam is hollowed to receive the line; and,
the line operatively coupling the first beam to the second beam, the line extending through a hollowed portion of the second beam and extending through a longitudinal hollow and an axial hollow of the first beam, the line configured to be repositionable with respect to at least one of the first beam and the second beam to cause the first and second beams to approach one another.
2. The apparatus of claim 1 , wherein:
the hollowed portion of the second beam comprises a longitudinal channel;
the longitudinal hollow of the first beam comprises an elongated channel; and,
the axial hollow of the first beam comprises an axial opening communicating with the elongated channel.
3. The apparatus of claim 2 , wherein:
the hollowed portion of the second beam includes an axial channel communicating with the longitudinal channel; and,
the line extends through the axial channel of the second beam and through the axial hollow of the first beam.
4. The apparatus of claim 1 , wherein:
the hollowed portion of the second beam comprises a longitudinal channel and at least two axial channels communicating with the longitudinal channel;
the longitudinal hollow of the first beam comprises an elongated channel;
the axial hollow of the first beam comprises at least two openings communicating with the elongated channel; and,
the line extends through a first of the at least two openings and into the second beam through a first of the at least two axial channels, and then through a second of the at least two axial channels and returns to the first beam via a second of the at least two openings.
5. The apparatus of claim 1 , wherein the line is resilient.
6. A method of positioning an occlusion device to clamp tissue, the method comprising:
slacking a line concurrently engaging a first beam and second beam to increase a gap between the first and second beams, where the line is coursed to exit a first opening in the first beam, enter a first opening in the second beam, exit a second opening in the second beam and enter a second opening in the first beam and exit a third opening in the first beam;
positioning the first and second beams to be interposed by tissue;
pulling on the line extending through the third opening to decrease the gap between the first and second beams to clamp the tissue therebetween.
