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 elongated tubular member including a distal section and a proximal section, wherein the distal section is radially expandable from a first configuration to a second expanded configuration through an application of a compressive force upon the distal section along the longitudinal axis;
wherein the proximal section defines an outer surface and includes a widened proximal portion member attached to the outer surface of the proximal section;
a binding material including an adhesive disposed on an interior surface of the elongate tubular member in the distal section, wherein the binding material is configured to maintain the distal section in the second expanded configuration after the distal section is radially expanded from the first configuration to the second expanded configuration;
wherein the elongated tubular member is adapted to permit an insertion device to extend through the elongated tubular member and extend distally therefrom such that withdrawing the insertion device applies the compressive force; and
a first non-return valve disposed within the proximal section.

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.

13. A medical device for closing an opening in a dural membrane of a patient, the 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; 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 an application of a compressive force upon the distal section, the distal section being adapted to permit an insertion device to extend therethrough such that withdrawing the insertion device applies the compressive force; a bonding agent disposed on an interior surface of the tubular distal section, wherein the bonding agent is configured to maintain the tubular distal section in the second expanded configuration after the tubular distal section is radially expanded from the first configuration to the second expanded configuration; and a non-return valve disposed within the tubular distal section. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
