Abstract
Described here are devices and methods for forming one or more tracts in tissue. The tracts may be formed in any suitable or desirable tissue, and may seal relatively quickly without the need for a supplemental closure device. In some variations, the methods may comprise clamping at least a portion of a tissue and advancing a tissue-piercing member through the clamped tissue to form a tract. The tract may, for example, provide access for one or more tools.

39. A method for forming a tract in tissue using a device comprising first and second curved surfaces that are opposed to each other and coupled at an attachment point, the first and second curved surfaces configured to move about the attachment point between a first collapsed position and a second outwardly displaced position, the method comprising:
-
moving the first and second curved surfaces from the second outwardly displaced position to the first collapsed position to clamp tissue between the first and second curved surfaces, wherein the first and second curved surfaces position at least a portion of the clamped tissue for piercing by a tissue-piercing member passing through a lumen defined by the device. - View Dependent Claims (40)
