Tissue clamp for noninvasive physiological measurement
First Claim
1. A device comprising:
- a clamp having a first jaw member and a second jaw member, the first jaw member having a jaw face and the second jaw member having a complementary face, the second jaw member held in alignment with the first jaw member by a joint, the joint having an elastic member configured to exert a compressive force between the jaw face and the complementary face, the joint configured to allow movement of the jaw face relative to the complementary face in directions corresponding to pitch, roll, yaw, and heave, and the compressive force distributed over a surface of the jaw face;
a sensor coupled to the jaw face, the sensor configured to generate a sensor signal corresponding to a physiological parameter of a tissue proximate the jaw face.

Abstract
A device includes a clamp and a sensor. The sensor can be permanently attached to the clamp and tissue by the force exerted by the clamp. The clamp includes a first jaw member and a second jaw member. The first jaw member has a jaw face and the second jaw member has a complementary face. The second jaw member is held in alignment with the first jaw member by a joint. The joint has an elastic member configured to exert a compressive force between the jaw face and the complementary face. The joint is configured to allow movement of the jaw face relative to the complementary face in directions corresponding to pitch, roll, yaw, and heave. The compressive force is distributed over a surface of the jaw face. The sensor is coupled to the jaw face or held in place by the compressive force of the jaw face. The sensor is configured to generate a sensor signal corresponding to a physiological parameter of tissue proximate the jaw face.

17. A system comprising:
-
a clamp including a pair of arms configured to articulate about a joint, each arm having a jaw portion and having a sensor coupled to the jaw portion of at least one arm, the sensor configured to provide a sensor output corresponding to a physiological parameter of tissue proximate the sensor, the joint configured to allow movement of the jaw portions in directions corresponding to pitch, roll, yaw, and heave; an elastic member coupled to the clamp and configured to exert a compressive force between the jaw portions, the compressive force distributed over a surface of the sensor; a processor coupled to the clamp and configured to generate a result based on the sensor output; and a display coupled to the processor and configured to generate visible data based on the result. - View Dependent Claims (18, 19, 20, 21, 22, 23)
