Surgical perforation device with curve
First Claim
1. A method of creating a perforation in a heart septum comprising the steps of:
- applying a form of energy to a perforation device positioned at a desired location of a heart septum to create a perforation at said desired location, wherein said perforation device comprises an elongate member having a proximal region and a distal region and wherein said distal region comprises a portion fixed in a desired curve shape; and
advancing a distal tip of the device through the septum, such that said distal tip is automatically directed away from cardiac structures while being advanced, due to the shape of the curved portion;
whereby said distal tip is directed away from said cardiac structures in order to decrease risk of unwanted injury.

Abstract
A device for creating a surgical perforation with a functional distal tip for creating a controlled perforation. The functional tip may comprise at least one active electrode for creating the perforation through the application of Radio Frequency (RF) energy. The device is curved in order to decrease the likelihood of injury to structures of a patient such as inadvertent cardiac perforation when used in transseptal perforation procedures. The device is introduced into the right atrium, and the functional tip is then positioned against the atrial septum. Energy is applied to create the perforation. The tip is advanced toward the left atrium to create the perforation and as it advances into the left atrium, the device takes on its curved shape to direct the tip away from cardiac structures. The position of the tip of the device can be determined in response to pressure sensed at the tip and determined by a monitor.
