Patent ID: 10065022

Abstract:
A tactile probe for endovascular intervention with feedbacks informative of the range and direction of a contact force includes: a central column (7); a plurality of lateral electrodes (2) around the central column (7); a conductive contact sleeve (1) that is axially and radially movable relative to the central column (7); a top electrode (3) in movable connection with the central column (7); and an alert electrode (4) configured to generate: a lateral contact signal, upon the contact sleeve (1) radially moving relative to the central column (7) and being electrically connected to at least one lateral electrode (2); a top contact signal, upon the contact sleeve (1) axially moving relative to the central column (7) a first distance (d1) and being electrically connected to the top electrode (3); and a warning signal, upon the contact sleeve (1) axially moving relative to the central column (7) a second distance (d2) and being electrically connected to the alert electrode (4). The tactile probe can identify the direction of the contact force and also indicate its magnitude.
