  • Publication number: 20130310667
    Abstract: A physiologic sensor device configured to be placed on an appendage. The sensor device includes a foldable portion designed to be deformed around the tip of the appendage. In some embodiments the foldable portion is a soft compressible material. In other embodiments a stabilization component is provided to isolate sensing elements from external forces. Some embodiments also include a deformable frame that folds in response to a bending force as the sensing device is placed on the appendage. The deformable frame holds the sensor device in place until another bending force is applied. In other embodiments the frame and/or sensor elements are removable and disposable relative to other components of the sensor device.

  • Publication number: 20080221420
    Abstract: A medical device configured to be temporarily secured at a tissue field, such as a fetal skull, via a spiral probe. The spiral probe functions to both secure the sensor in place and provide an electrode for ECG purposes. The spiral probe is non-uniform and includes one or more of a stop element, a cross bar element and a collapsed portion adapted to engage tissue after a predetermined rotation of the probe into the tissue field. The probe diameter can expand with an increase in torque applied to a drive rod, leading to disengagement of the drive rod from the probe. The spiral probe and drive rod may define a detent mechanism whereby upon reaching a predetermined torque the drive rod is disengaged from the probe and freely rotates without further entry of the spiral probe into the tissue field.

  • Patent number: 5688223
    Abstract: A retractor apparatus for use in conducting a surgical operation through an incision in a patient. The retractor includes a retractor support, a plurality of surgical retractors, and a stretchable sleeve. The surgical retractors are mounted to the retractor support such that at least two of the surgical retractors are facing each other. The stretchable sleeve encircles the surgical retractors to form a continuous surface around the surgical retractors for engagement of tissue.
