Expandable apparatus for electrophysiological sensing with staggered electrodes
A recently granted patent (Publication Number: US11771373B2) describes an apparatus for electrophysiological sensing. The apparatus includes a shaft designed for insertion into a subject's body and an expandable element attached to the distal end of the shaft. The expandable element consists of multiple electrodes and is constructed using an assembly of parallel splines. The electrodes are grouped into rows that are staggered with respect to each other and are coupled to the splines. The distance between successive electrodes on the same spline is denoted as D0, while adjacent splines are spaced apart by a distance that is not specified in the claims.
Claim 2 specifies that the distance D0 between successive electrodes on the same spline is between 1 and 5 mm. This range provides flexibility in electrode placement and allows for precise sensing of electrophysiological signals.
Claim 3 states that each electrode comprises a ring fitted over a respective spline. This design ensures secure attachment of the electrodes to the splines and facilitates accurate sensing of electrophysiological activity.
Claim 4 mentions that the expandable element consists of multiple looped elements, each comprising a different pair of splines. This configuration allows for expandability and adaptability of the apparatus, enabling it to conform to different anatomical structures within the body.
Claim 5 describes the arrangement of the electrodes in a hexagonal grid. This arrangement optimizes the coverage area and enhances the accuracy of electrophysiological sensing by ensuring that the electrodes are evenly distributed.
Overall, this granted patent presents an apparatus for electrophysiological sensing that utilizes an expandable element with multiple electrodes arranged in rows coupled to parallel splines. The design allows for precise electrode placement, adaptability to different anatomical structures, and optimal coverage area. The apparatus has potential applications in various fields, including medical diagnostics and research.
