PATENT FORAMEN OVALE CLOSURE SYSTEM

摘要

A tool for closing an opening in tissue may include a catheter, a clasp applicator positioned substantially at the distal end of the catheter; and at least one clasp held by the clasp applicator, where the clasp may include a plurality of tines and be plastically splayable by the clasp applicator. A patent foramen ovale in heart tissue may by closed by, for example, advancing that exemplary clasp applicator through the patient's vasculature to a location in proximity to the patent foramen ovale, anchoring the clasp applicator with respect to the patent foramen ovale, splaying the clasp, advancing the splayed clasp into contact with tissue; closing the clasp, and removing the clasp applicator from the heart.
