1. A sensor, comprising:
- a conformable sensor body having a tissue-contact surface;
an emitter and detector disposed on the tissue-contact surface in a reflectance configuration; and
a deformable element disposed on the sensor body on a surface opposing the emitter and the detector, wherein the deformable element is configured to cause a portion of the sensor body to protrude against a patient'"'"'s tissue when the sensor is applied such that the pressure applied by the sensor body is non-uniform across the tissue-contact surface and is highest in the area of the sensor body proximate to the emitter and the detector.

Abstract
Embodiments of the present disclosure relate to sensors for applying pressure to a patient'"'"'s tissue. According to certain embodiments, the sensors may include one or more deformable elements that hold the optical components of the sensor against the tissue with an appropriate amount of pressure. In additional embodiments, such sensors may include a rigid one-piece sensor body that incorporates a deformable element to facilitate fine-fitting of the sensor against the tissue.

16. A sensor, comprising:
-
a rigid sensor body comprising a first member and a second member configured to be applied to opposing sides of a patient'"'"'s tissue, wherein the first member and the second member are joined to one another such that their relative positions are fixed. an emitter and detector disposed on a rigid surface on an end of the first member in a reflectance configuration; and a deformable element disposed on an end of the second member, wherein the deformable element is configured to be positioned between the patient'"'"'s tissue and the second member, and wherein the deformable element is configured to expand towards the patient'"'"'s tissue. - View Dependent Claims (17, 18)

19. A sensor, comprising:
-
a conformable sensor body having a tissue-contact surface; an emitter or a detector disposed on the tissue-contact surface in a reflectance configuration; and a deformable element disposed on the sensor body on a surface opposing the emitter and the detector, wherein the deformable element is configured to cause the sensor body to assume a non-planar configuration, wherein the non-planar configuration is stable in the absence of a biasing force. - View Dependent Claims (20)
