  • Patent number: 9816885
    Abstract: An optical force sensing element for microsurgical instruments and methods measures force F in three orthogonal directions and includes a monolithic cylinder structure, a cylindrical surface and a top surface that absorbs and transmits the force F. Three punch-like notches, all being parallel to the y-direction, are spaced apart along the z-axis and form two blades between the first and second notch and between the second and the third notch. Three channels parallel to the z-axis extend from the bottom surface to the top surface and cross the first notch while bypassing the other two notches. Three optical fibers, each fixed in one of the three channels, all entering the structure from the bottom surface, cross the first notch and end at or near the top surface while being interrupted in the first notch and forming two surfaces of each fiber that define a Fabry-Perot interferometric cavity.

  • Patent number: 9775966
    Abstract: A catheter system includes a handle and a catheter component operatively connected to the handle for selective adjustment by an actuator associated with the handle housing. The actuator comprises at least in part a generally cylindrical shuttle disposed at least in part within the housing for longitudinal movement. The catheter component is operatively coupled to the shuttle for movement therewith. The shuttle has an outer surface with an annular groove formed therein, and an elastomeric ring seated in the annular groove. An annular slide bearing is retained in the housing, with the shuttle being in part disposed in the annular groove and with the elastomeric ring in frictional contact with the slide bearing. Friction between the elastomeric ring and the slide bearing is sufficient to frictionally retain the shuttle at a selected longitudinal position relative to the housing corresponding to a selected adjustment of the catheter component.

  • Patent number: 9750413
    Abstract: Diffuse optical tomography systems and methods are described herein. In a general embodiment, the diffuse optical tomography system comprises a plurality of sensor heads, the plurality of sensor heads comprising respective optical emitter systems and respective sensor systems. A sensor head in the plurality of sensors heads is caused to act as an illuminator, such that its optical emitter system transmits a transillumination beam towards a portion of a sample. Other sensor heads in the plurality of sensor heads act as observers, detecting portions of the transillumination beam that radiate from the sample in the fields of view of the respective sensory systems of the other sensor heads. Thus, sensor heads in the plurality of sensors heads generate sensor data in parallel.
