A device which facilitates the closure of puncture wounds in the vasculature of a patient is used in conjunction with a guidewire, and helps locate and isolate the site of the puncture wound in the patient. The retractor moves the surrounding tissue laterally when positioned in the patient, and acts as a guide for the physician in locating the exact site of the wound. A double-sleeved balloon can be used in conjunction with the retractor to move the tissues laterally and form a tunnel from the surface of the patient's body to the puncture site. The retractor is preferably used in combination with a surgical clip applicator which delivers clips to the site of the wound, but can also be used with other methods of wound closure such as suturing and stapling. |
