Minimally invasive occlusion device and methods thereof
A minimally invasive occlusion device is disclosed. The minimally invasive occlusion device includes a first link having a first end and a second end, a second link having a first end and a second end; the first end of the second link connected to the first end of the first link by a compensating coupler. Another minimally invasive occlusion device may include a delivery frame or a shaft having an articulating cradle coupled to the shaft. A method of occluding tissue is also disclosed. The method of occluding tissue includes placing a first link of an occlusion device laterally at a base of tissue, placing a second link of an occlusion device on an opposing side of the base of tissue, substantially parallel with the first link, and securing the first link and the second link to fully occlude the base of tissue.
1. A minimally invasive surgical assembly comprising:
an occlusion device for occluding a left atrial appendage of a patient, the occlusion device comprising:
an elongated first link comprising a first end and a second end; and
an elongated second link comprising a first end and a second end, wherein the first end of the second link is pivotably coupled to the first end of the first link; and
a delivery device, the delivery device comprising a rigid frame having a receiving aperture adapted to receive at least a portion of the left atrial appendage of the patient, the receiving aperture having a first edge, a second edge, and a third edge that cooperate to form a triangular enclosure, wherein the first link of the occlusion device is removably coupled to a first portion of the frame such that the first link is parallel to the first edge of the receiving aperture and the second link of the occlusion device is removably coupled to a second portion of the frame such that the second link is parallel to the second edge of the receiving aperture.
2. The minimally invasive surgical assembly of claim 1 , the first link further comprising a filament channel.
3. The minimally invasive surgical assembly of claim 1 , the first link further comprising an aperture at the first end and an aperture at the second end.

7. The minimally invasive surgical assembly of claim 6 , the compensating coupler comprising a filament that is:
slidable in a longitudinal direction along the first link; and
slidable in a longitudinal direction along the second link.
8. The minimally invasive surgical assembly of claim 7 , the compensating coupler further comprising suture.
9. The minimally invasive surgical assembly of claim 1 , the first link and the second link each comprising an opposing interdigitating surface.
10. The minimally invasive surgical assembly of claim 1 , wherein the frame further comprises a filament channel.
11. The minimally invasive surgical assembly of claim 1 , wherein the frame further comprises a filament aperture.
12. The minimally invasive surgical assembly of claim 1 , wherein the frame is comprised of a translucent material.
13. The minimally invasive surgical assembly of claim 1 , wherein the frame is comprised of a transparent material.
14. The minimally invasive surgical assembly of claim 1 , further comprising at least one filament lumen.
