Publication number: 20210307823Abstract: A method of perforating a tissue of a heart of a patient when an inferior approach to the heart is contraindicated. The method utilizes an electrosurgical apparatus having an energy delivery device which can function as an ECG measuring device at a distal end thereof and a delivery system comprising a dilator. Said method comprises the steps of (a) advancing the dilator through a superior vena cava into the heart of the patient, from a superior approach, until a distal end of the dilator is adjacent the tissue; (b) checking an ECG signal to confirm a position of the energy delivery device; (c) using the electrosurgical apparatus, which is positioned through the dilator, to create a perforation in the tissue by delivering electrical energy to the tissue; (d) advancing the distal end of the electrosurgical apparatus through the perforation; and (e) advancing the dilator over the electrosurgical apparatus.Type: ApplicationFiled: June 17, 2021Publication date: October 7, 2021Inventors: John Paul Urbanski, Matthew Paul Joseph DiCicco, Bahe Achem, Gareth Davies, Amanda Hartley, Naheed Visram, Krishan Shah, Frank Baylis

Patent number: 7270662Abstract: A device with a functional tip containing at least one active electrode capable of creating a controlled perforation in body tissue through the application of energy (e.g. Radio Frequency (RF)) is described. The position of the tip of the device can be determined in response to ECG measured at the tip and determined by a monitor coupled to the device. The device is useful to remove or perforate unwanted tissue in a controlled manner in any location in the body, particularly in the atrial septum for controlled transseptal puncture. In this application, the device is introduced into the right atrium, and the functional tip is then positioned against the atrial septum. ECG is used to locate the region of the fossa ovalis on the atrial septum. Energy is applied to create the perforation and ECG is monitored to determine if the perforation was created in a desired location.Type: GrantFiled: January 21, 2004Date of Patent: September 18, 2007Inventors: Naheed Visram, Krishan Shah

Patent number: 7048733Abstract: 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.Type: GrantFiled: September 19, 2003Date of Patent: May 23, 2006Assignee: Baylis Medical Company Inc.Inventors: Amanda April Hartley, Krishan Shah, Naheed Visram, Frank Baylis
