Vessel closure device
First Claim
1. A method for installing a tissue closure device, the method comprising:
- locating an opening in tissue;
positioning a closure device adjacent the opening, the closure device having a proximal annular cap and a coiled wire extending from adjacent the annular proximal cap, an elongate member extends through a portion of the coiled wire, the coiled wire increasing in diameter from the proximal annular cap toward a distal end of the closure device, a diameter of the proximal annular cap being larger than a diameter of the coiled wire adjacent the proximal annular cap and at least a diameter of an intermediate portion of the coiled wire; and
deploying the proximal annular cap and the coiled wire of the closure device distally into the opening to engage the coiled wire with the tissue surrounding the opening, the coiled wire engages and pulls the tissue surrounding the opening radially inwardly and reduces blood-loss by the patient after deployment.

Abstract
The present invention relates to closing an opening within a subcutaneous bodily vessel by using a spiral closure device to engage tissue around the opening. The spiral closure device is adapted to be threaded into the vessel wall surrounding the opening in the bodily vessel. A deployment mechanism may be used to rotate the spiral closure device. As the deployment mechanism is rotated the spiral closure device is rotated such that a tip of the spiral closure device engages the vessel wall around the opening in the bodily vessel. Continued rotation of the spiral closure device threads the closure device through the tissue around the opening. The closure device may have a tapered configuration in which the distal end is larger than the proximal end. As the distal end is threaded through the vessel wall, the narrowing closure device pulls the vessel wall tissue together, thereby effectively closing the opening.

9. A method for reducing blood-flow following a medical procedure, the method comprising:
-
locating an opening in a tissue wall through which a medical procedure was performed; positioning a tissue closure device at the opening, the closure device including a proximal annular cap and a coiled wire with a sharpened distal tip, an elongate member extends through a portion of the coiled wire, the coiled wire increasing in diameter from the proximal annular cap toward a distal end of the closure device, a diameter of the proximal annular cap being larger than a diameter of the coiled wire adjacent the annular cap and at least a diameter of an intermediate portion of the coiled wire; advancing the closure device distally into the tissue wall surrounding the opening; and deploying the closure device to engage the coiled wire with the tissue wall to engage and pull the tissue surrounding the opening radially inwardly, the combination of the coiled wire and the elongate member reducing blood-loss by the patient after deployment of the closure device in the tissue wall. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method for installing a tissue closure device so as to reduce blood-loss by the patient, the method comprising:
-
locating an opening in a tissue wall; positioning a deployment mechanism at the opening, the deployment mechanism supporting a tissue closure device, the closure device having a proximal annular cap and a coiled wire extending from adjacent the annular cap, an elongate member extends through a portion of the coiled wire, the coiled wire increasing in diameter from the proximal annular cap toward a distal end of the closure device, a diameter of the proximal annular cap larger than a diameter of the coiled wire adjacent the proximal annular cap and at least a diameter of an intermediate portion of the coiled wire; and rotating the deployment mechanism to deploy the tissue closure device distally into the tissue wall to engage and pull together the tissue wall surrounding the opening and to reduce blood-loss by the patient by traversing a plunger, disposed within a tube of the deployment mechanism, along an axis of the tube. - View Dependent Claims (17, 18, 19, 20)
