Systems and methods are provided for generating a high density (HD) map for identifying a location and/or an orientation of an electromagnetic (EM) sensor within an EM volume in which an EM field is generated by way of an antenna assembly. A measured EM field strength at each gridpoint of a set of gridpoints of the EM volume are received from a measurement device. An EM field strength at each gridpoint of a second set of gridpoints of the EM volume is calculated based on a geometric configuration of an antenna of the antenna assembly. The HD map is generated based on the measured EM field strength at each gridpoint of the first set of gridpoints and the calculated EM field strength at each gridpoint of the second set of gridpoints.

The apparatus includes a pulse generator coupled to the electroporation catheter, and a computing device coupled to the pulse generator, the computing device operable to control the pulse generator to selectively energize the plurality of electrodes on the electroporation catheter to form an energization pattern.

A surgical instrument comprising a housing, a shaft, an end-effector, a cutting member, and a control circuit is disclosed. The housing comprises a motor. The end-effector comprises a first jaw, a second jaw movable relative to the first jaw, an anvil, and a staple cartridge comprising staples, driver elements, and a sled configured to eject the staples toward the anvil. The sled is movable between a proximal unfired position and a distal fired position through a firing stroke. The cutting member is configured to be advanced distally into the sled by the motor. The control circuit is configured to detect the location of the cutting member, monitor a parameter indicative of a load experienced by the cutting member, determine a threshold value of the parameter based on a portion of the firing stroke, and adjust operation of the motor if the monitored parameter exceeds the determined threshold value.

A system and method for determining a position of a medical device within a body are provided. The system includes an electronic control unit that receives position signals from position sensors of a first type and a second type disposed on the device and applies a filter to each of the position signals to obtain filtered estimated positions for each sensor. The unit computes a spline connecting the position sensors of the first type responsive to the filtered estimated positions for the sensors and estimates a spline position for the sensor of the second type along the spline. The unit generates maps between the spline position and filtered and unfiltered estimated positions for the sensor of the second type and determines actual positions for the sensors of the first type responsive to the filtered estimated position for the sensors and a composite map of the two maps.

A method and system for automatic location of a target treatment structure, such as a pulmonary vein ostium, from an anatomical image. The method includes calculating a most likely path of blood flow through a pulmonary vein based on a cross-sectional area minimization technique and calculating pulmonary vein geometry as a function of length. For example, a pulmonary vein ostium may be located by analyzing a change in pulmonary vein dimensional size or other anatomical factors, such as absolute size. The method may also include determining tissue thickness at the pulmonary vein ostium or other treatment size for treatment dose optimization. The method may be an algorithm performed by a processing unit of a navigation system or other component of a medical system.
