Abstract

Among other things, there is disclosed structure and methods for maintaining access to a location in the body while reducing or eliminating the potential for pulling an access device (e.g. a catheter) back through an opening. An introducer sheath includes a distal indented portion and a balloon, so that once placed in a desired location through tissue, the balloon can be inflated to anchor the sheath against retraction. In particular embodiments, structure and methods for accessing the pericardial cavity via the right atrial appendage are shown.
