Physiological Sensor Delivery Device - US12605075B2
Summary
USPTO granted patent US12605075B2 to ACIST Medical Systems, Inc. on April 21, 2026, covering an intravascular sensor delivery device and method for measuring physiological parameters such as blood pressure within vascular structures. The device is sized to pass over guidewires for use in coronary and peripheral arteries and can measure pressure gradients across stenotic lesions or heart valves. The patent contains 19 claims with a filing date of April 19, 2021.
What changed
USPTO issued patent US12605075B2 to ACIST Medical Systems, Inc., covering an intravascular sensor delivery device designed to measure physiological parameters within vascular structures or passages. The device can measure blood pressure and pressure gradients across stenotic lesions or heart valves, and is sized for use over guidewires in both coronary and peripheral arteries.
Medical device manufacturers developing pressure measurement or intravascular sensing technologies should review this patent when assessing freedom-to-operate for similar sensor delivery platforms. The patent's broad claim scope covering sensor delivery over guidewires may be relevant to competitive product development in the hemodynamic monitoring space.

Abstract
An intravascular sensor delivery device for measuring a physiological parameter of a patient, such as blood pressure, within a vascular structure or passage. In some embodiments, the device can be used to measure the pressure gradient across a stenotic lesion or heart valve. The sensor delivery device can be sized to pass over different sizes of guidewires to enable usage in coronary and peripheral arteries, for example.
