Abstract
Devices and methods are described for sealing tissue such as melding the two flaps of the foramen ovale together without the need for a permanent implant or closing openings in vessels.
Claims9
A method for treating an opening in or separated tissue, method comprising:
- positioning a catheter system having a first moveable part and a second moveable part adjacent to the opening and between adjacent edges of tissue such that the second moveable part does not penetrate the tissue, where the first moveable part comprises a helical member;
- advancing the helical member over the second moveable part, such the helical member penetrates and winds through at least a portion of the adjacent edges of tissue;
- compressing the helical member together to draw the adjacent edges of tissue together and apply force on the tissue;
- and
- applying force to the tissue while heating the tissue in order to close or fasten the adjacent edges of tissue.

A method for closing an anatomic defect in patent foramen ovale, the method comprising:
- engaging a heating member between adjacent sides of the patent foramen ovale by advancing a helical structure of the heating member through adjacent sides of the patent foramen ovale such that the helical structure winds through multiple locations along a length of at least one of the sides of the patent foramen ovale that is parallel to the opposite side of the patent foramen ovale, where the helical structure comprises a shape memory alloy;
- energizing the helical structure to draw the helical structure together to apply a force against the tissue;
- and
- applying heat with the heating member.
