1. A method of penetrating the tissue wall of an anatomical cavity, comprising:
- (a) inserting a portion of a backstop apparatus into the anatomical cavity through a first tissue opening, said backstop apparatus having a backstop; and
(b) manipulating said backstop apparatus in order to direct the urging of a penetration member through the tissue wall of said cavity at a penetration site spaced away from said first tissue opening, wherein said manipulating step is performed while a portion of said backstop apparatus extends through said first tissue opening; and
(c) urging a penetration member through the tissue wall of said cavity at said penetration site towards said backstop.

Abstract
An instrument for directing the insertion of a penetration member urged through tissue. The instrument includes a shaft, and a backstop positioned at a distal end of the shaft. The backstop and shaft are configured such that the backstop may be positioned adjacent one side of the tissue to be penetrated, and a penetration member may thereafter be urged through the opposite side of the tissue into the backstop. A method of penetrating the tissue wall of an anatomical cavity is also provided.
