  • Patent number: 11439330
    Abstract: A laparoscopic medical device includes an oximeter sensor at its tip, which allows the making of oxygen saturation measurements laparoscopically. The device can be a unitary design, wherein a laparoscopic element includes electronics for the oximeter sensor at a distal end (e.g., opposite the tip). The device can be a multiple piece design (e.g., two-piece design), where some electronics is in a separate housing from the laparoscopic element, and the pieces (or portions) are removably connected together. The laparoscopic element can be removed and disposed of; so, the electronics can be reused multiple times with replacement laparoscopic elements. The electronics can include a processing unit for control, computation, or display, or any combination of these. However, in an implementation, the electronics can connect wirelessly to other electronics (e.g., another processing unit) for further control, computation, or display, or any combination of these.

  • Patent number: 11432763
    Abstract: A method differentiates a blood vessel from a nonvascular tissue during a minimally invasive surgery using a device. A device may be any penetration sensor device, such as a dilator sensor device, a hollow needle sensor device, or a trocar sensor device, which penetrates the skin and subcutaneous layers to reach a target location inside the body. The penetration sensor device includes a sensor probe which can make optical measurements to determine various parameters of the tissue at the tip of the sensor probe. These parameters may include an optical signal level returned from tissue contacting the tip of the sensor probe, an oxygen saturation level of the tissue, a total hemoglobin concentration, a blood flow, and a pulse. Based on these parameters, the presence or absence of a blood vessel at the tip of the penetration sensor device can be determined while the device travels towards the target location for surgery.

  • Patent number: 11419528
    Abstract: A method for determining oxygen saturation includes emitting light from sources into tissue; detecting the light by detectors subsequent to reflection; and generating reflectance data based on detecting the light. The method includes determining a first subset of simulated reflectance curves from a set of simulated reflectance curves stored in a tissue oximetry device for a coarse grid; and fitting the reflectance data points to the first subset of simulated reflectance curves to determine a closest fitting one of the simulated reflectance curves. The method includes determining a second subset of simulated reflectance curves for a fine grid based on the closest fitting one of the simulated reflectance curves; determining a peak of absorption and reflection coefficients from the fine grid; and determining an absorption and a reflectance coefficient for the reflectance data points by performing a weighted average of the absorption coefficients and reflection coefficients from the peak.

  • Patent number: 11375925
    Abstract: A sensor probe has a connector and the connector's corresponding receptacle on a console have security mechanisms that ensure that the connector and the receptacle are properly connected and mated. The connector and receptacle can have physical security features that block insertion of the connector into the receptacle if they are not aligned in a proper orientation. The console can also include a software security feature that allows optical measurements from the sensor probe only if the connector of the sensor probe and receptacle on the console are connected properly. An adapter can also be used to convert a conventional receptacle mounted on a console into a receptacle with security features.

  • Patent number: 10939853
    Abstract: A sensor head for a compact oximeter sensor device includes light sources and light detectors. A compact oximeter sensor device implementation is entirely self-contained, without any need to connect, via wires or wirelessly, to a separate system unit. The sources and detectors are arranged in a circular arrangement having various source-detector pair distances that allow for robust calibration and self-correction in a compact probe. Other source-detector arrangements are also possible.

  • Patent number: 10905332
    Abstract: A bone oximeter probe includes an elongated member and a sensor head at an end of the elongated member to make measurements for a bone. The measurements can indicate the viability or nonviability of the bone. In an implementation, the probe is advanced through an incision in soft tissue, towards the underlying bone, and positioned so that the sensor head faces the bone to be measured. Optical signals are sent from the sensor head and into the bone. The bone reflects some of the optical signals which are then detected so that measurements for the bone can be made. Some of these measurements include an oxygen saturation level value, and a total hemoglobin concentration value of the bone.

  • Patent number: 10849536
    Abstract: An oximeter probe is user configurable for being in an absolute reporting mode and a relative reporting mode for measured values. The measured values for the absolute and relative modes include absolute oxygen saturation, relative oxygen saturation, absolute hemoglobin content, relative hemoglobin content, absolute blood volume, relative blood volume. The relative modes and absolute modes for determining and reporting relative or absolute hemoglobin content or relative or absolute blood volume for individual patients are beneficial when determining the efficacy of administered medications, such as epinephrine, that effect blood flow, but not oxygen saturation, in tissue, such as skin. The oximeter probe in these relative modes displays the efficacy of the administered medication as reported values for relative hemoglobin content or relative blood volume fall or rise.

  • Patent number: 10835227
    Abstract: A retractor system includes a retractor with an oximeter sensor at its tip and a force sensor coupled to the retractor. The retractor system also includes a system unit which can send signals to and receive signals from the oximeter sensor via optical fibers. The oximeter sensor measures oxygen saturation of a tissue being retracted by the retractor, and the force sensor measures an amount of force that is applied to the retracted tissue by the tip of the retractor. Another retractor system has a closed loop control arrangement with a positioning mechanism which moves the retractor based on measurements of the sensors.

  • Patent number: 10827957
    Abstract: An oximeter probe includes a probe unit or a base unit and a probe tip where the probe tip has a number of sources and detectors that can be accessed individually or in differing combinations for measuring tissue oxygen saturation at different tissue depth in tissue. A processor of the oximeter probe controls a multiplexer that is coupled to the detectors for selectively collecting measurement information from the detectors via the multiplexer. The oximeter probe is user programmable via one or more input devices on the oximeter probe for selecting the particular sources and detectors to collect measurement information from by the processor.
