Closing openings in anatomical tissue
First Claim
1. A medical system configured to close one or more openings, each of the one or more openings leading to an anatomical cavity, at least a portion of the medical system sized in at least one configuration to be deliverable through a first opening of the one or more openings into the anatomical cavity, and the at least the portion of the medical system comprising:
- an elongated member, a portion of the elongated member sized to be deliverable through the first opening into the anatomical cavity;
a closure unit releasably coupled to the elongated member and arranged to be delivered into the anatomical cavity to a location at least proximate an interior tissue surface within the anatomical cavity, the closure unit further arranged to close an opening of the one or more openings located on the interior tissue surface within the anatomical cavity; and
an intermediate member releasably coupled to the elongated member and arranged to be delivered into the anatomical cavity to a location between at least part of the closure unit and the interior tissue surface within the anatomical cavity,wherein the closure unit comprises at least one piercing element, each piercing element of the at least one piercing element arranged to point back toward the elongated member in a state prior to any piercing of the interior tissue surface by the piercing element of the at least one piercing element and in which the closure unit is coupled to the elongated member of the at least one piercing element, and each piercing element of the at least one piercing element arranged to pierce through the intermediate member and pierce through the interior tissue surface into tissue surrounding the anatomical cavity.

Abstract
A device for closing at least one opening leading to an anatomical cavity is delivered via a catheter positioned in a first opening leading to the anatomical cavity. An orientation control unit is positioned within the anatomical cavity. The orientation control unit defines an orientation of a portion of a tissue surface within the anatomical cavity that is skewed with respect to the first opening and orients a closure member of the device with the tissue surface. An occluding member and a constricting unit of the device are positioned within the anatomical cavity with the occluding member blocking a portion of an opening that is constricted by the constricting unit. An intermediate member of the device is positioned within the anatomical cavity and a closure unit employing at least one piercing element pierces through the intermediate member into a tissue wall surrounding the anatomical cavity.
