ACCESS NEEDLE WITH DIRECT VISUALIZATION AND RELATED METHODS

摘要

Systems and methods for epicardial electrophysiology and other procedures are provided in which the location of an access needle may be inferred according to the detection of different pressure frequencies in separate organs, or different locations, in the body of a subject. Methods may include inserting a needle including a first sensor into a body of a subject, and receiving pressure frequency information from the first sensor. A second sensor may be included with the access needle to provide image data and/or cardiac waveform information of the subject.

主权项

1. A system for accessing one or more locations of a subject, said device comprising:
an access needle having a first lumen, a second lumen, a distal end and a proximal end; a first sensor configured for sensing pressure frequency in the one or more locations of the subject, and accommodated in at least one of the first or second lumens; an imaging device configured for obtaining image data in the one or more locations of the subject, and accommodated in at least one of the first or second lumens; an illumination device configured for illuminating the one or more locations of the subject, and accommodated in at least one of the first or second lumens; a second sensor configured for sensing temperature in the one or more locations of the subject while illuminating the one or more locations of the subject, and accommodated in at least one of the first or second lumens.
