Medical closure device
First Claim
1. A medical device for closing an opening in a tissue in a body of a patient, the device comprising:
- an elongated tubular member extending along a longitudinal axis, the tubular member including a distal section and a proximal section, wherein the distal section is expandable from a first configuration to a second expanded configuration through the application of a predetermined compressive force upon the distal section along the longitudinal axis.

Abstract
Several alternative designs, structures, assemblies, treatment methods and/or methods of manufacturing medical closure devices adapted and/or configured for closing an opening, for example, an incision or a puncture in the tissue of a patient, for example, the dural membrane of a patient. Some embodiments include a medical closure device including an elongated tubular member extending along a longitudinal axis. The tubular member including a distal section and a proximal section, and the distal section is expandable from a first configuration to a second expanded configuration through the application of a compressive force upon the distal section along the longitudinal axis.

33. A method for closing an opening in a dural membrane of a patient, the method comprising:
-
providing a closure device comprising a tubular proximal section defining an outer surface having an outer perimeter, a tubular intermediate section connected to the proximal section, the intermediate section defining an outer surface having an outer perimeter that is less than the outer perimeter of the proximal section, and a tubular distal section connected to the intermediate section, the distal section being configured to be radially expandable from a first configuration to a second expanded configuration through the application of a predetermined compressive force upon the distal section;
inserting the device into the opening while the distal section is in the first configuration such that the distal section extends through the opening, the intermediate section extends within the opening, and the proximal section remains outside of the opening; and
applying a predetermined compressive force to the distal section along the longitudinal axis to expand the distal section from the first configuration to the second expanded configuration. - View Dependent Claims (34, 35, 36, 37, 38, 39)
