Problems solved by technology

[0006] However, if such a map is constructed with respect to an external frame of reference (e.g., an electromagnetic field created outside the patient), then in some common situations, for example, when the patient moves relative to the externally generated frame of reference and / or one of the When some physiological parameters change (e.g. changes in lung volume, respiratory cycle, volume status, etc.), the created plots may suffer from significant inaccuracies

Embodiment Construction

[0017] Go to attached image, figure 1 and figure 2 Shown is an exemplary arrangement of instruments that may be provided in a cath lab or other setting that may include system 1 to facilitate imaging and / or otherwise performing a medical procedure within patient body 90, for example, while patient 90 is lying on an operating table 2 hours. Generally, the system 1 includes a field generator 4 mounted to or provided adjacent to the table 2, e.g., positioned and / or oriented to generate a field generator 4 surrounding an anatomical region of interest (e.g., including the patient's heart 92). electromagnetic field. As further described elsewhere herein, the electromagnetic field can provide an external frame of reference that remains substantially stationary relative to station 2, and within this external frame of reference one or more devices can be identified and located, such as figure 1 Catheter 10 is shown to facilitate positioning and / or maneuvering the device within the ...

Abstract

The present invention is directed to systems and methods for imaging during medical procedures and to apparatus and methods for making and using catheters including positional sensors for imaging systems for such procedures. The system is provided for facilitating imaging a patient during a medical procedure that includes an electromagnetic field generator for generating an electromagnetic field around a desired region of a patient's body to provide an external reference frame; an elongate member comprising a proximal end, a distal end sized for introduction into the patient's body, and a distal portion carrying a plurality of sensors spaced apart from one another such that the sensors may be positioned within the patient's body; and a processor for receiving signals from the sensors generated in response to the electromagnetic field, the processor configured to identify when the plurality of sensors move relative to the external reference frame to identify corresponding movement of the patient's body.

Description

[0001] relevant application data [0002] This application claims the benefit of co-pending U.S. Provisional Application Serial No. 62 / 681813, filed June 7, 2018, the entire disclosure of which is expressly incorporated herein by reference. technical field [0003] The present invention generally relates to systems and methods for improved imaging in medical procedures, such as cardiovascular procedures, and apparatus and methods for making and using catheters that include position sensors for imaging systems of such procedures. More particularly, the present invention relates to catheter devices including position sensors to improve the accuracy of cardiac electroanatomical maps, and systems and methods for using such devices. Background technique [0004] Electro-anatomical mapping has become a common adjunct to interventional cardiology procedures. In particular, the technology is used in electrophysiology suites to enable accurate placement of catheters in the heart, fo...
