26. A method comprising:
-
creating a tract between an exterior portion of a tissue and a lumen defined by the exterior portion of the tissue, wherein the tract includes at least two sloped regions, and the tract seals when blood pressure acts on the tissue. - View Dependent Claims (27, 28, 29)

30. A method comprising:
-
introducing a device comprising a first introducer and a second introducer into a tissue to create a tract between an exterior portion of the tissue and a lumen defined by the exterior portion of the tissue, wherein the device further comprises a pressure check port and a sensor in fluid communication with the pressure check port, and the tract seals when blood pressure acts on the tissue. - View Dependent Claims (31, 32, 33, 34, 35, 36)

37. A method for forming a self-sealing opening in tissue comprising:
-
advancing an introducer into the tissue to form a tract including at least two sloped regions; and
identifying a location of a portion of the tissue with the introducer, wherein the tract collapses under mechanical pressure to self-seal. - View Dependent Claims (38, 39, 40)

41. A method comprising:
introducing an introducer into tissue; and
traversing the introducer through the tissue to form a tract in the tissue, wherein the tract includes at least two sloped regions, and the tract becomes sealed when blood pressure acts on the tissue.- View Dependent Claims (42, 43, 44)

45. A method for forming a self-sealing arteriotomy comprising:
-
introducing a first introducer through an artery wall into a lumen of the artery;
introducing a second introducer into the artery wall to form a substantially lateral tract within the artery wall; and
advancing the second introducer into the lumen of the artery, wherein the tract includes at least two sloped regions, and the tract becomes sealed after removal of the first and second introducers, when blood pressure acts on the artery wall. - View Dependent Claims (46, 47, 48)

49. A device for forming a self-sealing opening in tissue comprising:
-
a first introducer for creating an opening through a tissue wall into a lumen of the tissue, wherein at least a portion of the first introducer is configured to locate an inner surface of the lumen wall; and
a second introducer for creating a substantially horizontal opening through the tissue wall, wherein the first and second introducers are part of a single device and at least one of the first and second introducers has a preformed shape comprising one or more bends, wherein at least one of the one or more bends has an angle in the range of about 1 to about 120°
