Abstract
Systems and methods for transeptal cardiac procedures are disclosed. A patient treatment system in accordance with a particular embodiment includes a catheter, a tissue penetration device carried by and deployable from the catheter, an energy delivery device carried by an deployable from the catheter, a backstop surface carried by the catheter, and a flexible, resilient tissue compression device. The tissue compression device can be coupled between the energy delivery device and the catheter and can be changeable between a first configuration in which the energy delivery device applies a first force to the backstop surface via intervening tissue, and a second configuration in which the energy delivery device applies no force or a second force less than the first force into the backstop surface via intervening tissue.
