A method includes, inserting a catheter into a cavity of a patient organ for performing a medical procedure, the cavity is of a given cavity type. A partial anatomical mapping of the cavity is performed by visiting one or more anatomical points on a surface of the cavity, using the catheter. Based on the partial anatomical mapping, a Graphical User Interface (GUI) template is selected, which is specified for applying the medical procedure to the given cavity type. The selected GUI template is presented to a user for performing the medical procedure in the cavity.

Ablation catheters and systems include coaxial catheter shafts with an inner lumen for delivering an ablative agent and an outer lumen for circulation of a cooling element about the catheter. Induction heating is used to heat a chamber and vaporize a fluid within by wrapping a coil about a ferromagnetic chamber and providing an alternating current to the coil. A magnetic field is created in the area surrounding the chamber which induces electric current flow in the chamber, heating the chamber and vaporizing the fluid inside. Positioning elements help maintain the device in the proper position with respect to the target tissue and also prevent the passage of ablative agent to normal tissues.

Surgical instruments with sensors for detecting tissue properties, and system using such instruments

A system is provided that furnishes expert procedural guidance based upon patient-specific data gained from surgical instruments incorporating sensors on the instrument's working surface, one or more reference sensors placed about the patient, sensors implanted before, during or after the procedure, the patient's personal medical history, and patient status monitoring equipment. Embodiments include a system having a surgical instrument with a sensor for generating a signal indicative of a property of a subject tissue of the patient, which signal is converted into a current dataset and stored. A processor compares the current dataset with other previously stored datasets, and uses the comparison to assess a physical condition of the subject tissue and/or to guide a procedure being performed on the tissue.

Method and system for mapping and analyzing cardiac electrical activity

A multiple-point basket-type or crown-shaped catheter device provides simultaneously mapping over a three-dimensional (3D) region of a subject, such as, one or more chambers of a subject's heart. The catheter device may include a series of splines each having a wave-like profile formed of a periodic series of peaks and troughs, with electrodes located at the peaks and troughs for mapping purposes.
