Surgical perforation device with curve
First Claim
1. A device for creating a perforation in material within a patient comprising:
- an elongate member having a proximal region and a distal region capable of adopting a curved shape; and
a functional tip at the distal region for delivering energy to create the perforation in the material;
wherein when the functional tip advances through the material, the distal region adopts a curved shape to direct the functional tip in a desired direction.

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.
