  • Publication number: 20080097213
    Abstract: Medical devices are made visible under ultrasonic or magnetic imaging techniques by adding a series of features on their surfaces. The features are desirably placed at more than one angle to the surface in order to enhance the visibility of the surface. Laser-machining can make a series of depressions or voids that are symmetric with respect to the surface and another series of depressions or voids that are non-symmetric. The pattern of voids is also varied by using more than one size of void, the depth of the voids, and the distribution of voids, i.e. more voids in some areas than others.

  • Publication number: 20080097214
    Abstract: An ultrasonic probe assembly comprises a housing defining a longitudinal axis and having a linear motor assembly, a swivel base, and an extension arm disposed therewithin. An imaging transducer is mounted on a free end of the extension arm and is specifically adapted to be moved along an arcuate path as a result of mechanical interconnection of the swivel base to the linear motor assembly. The swivel base upon which the extension arm is mounted is configured to be pivotable about a pivot axis oriented transversely relative to the longitudinal axis such that reciprocative motion of the linear motor assembly is converted in swiveling motion of the swivel base and oscillating translation of the transducer along an arcuate path such that the transducer axis is oriented generally perpendicularly relative to an anatomical structure having a convexly shaped outer surface.

  • Publication number: 20080097221
    Abstract: Systems for highly efficient, in-vivo collection of modulated infra-red light are presented. Specifically, these devices are arranged in an important format with a view to integration with a wristwatch or other wearable device. An optical aperture of large surface area, specially distributed in an annular ring, receives radiation having been modulated in a tissue test site by blood flow. Radiation received about the annular aperture is redirected by a blazed grating or similar optical element at near perpendicular angles, into a radially distributed, condensing light pipe array and further toward a common axis. Radiation converges on the axis, thus increasing the energy density of the collected signal, before it is further directed via a conic element to a detector such as a photodiode. In some versions, these highly specialized optical paths may be formed into a single element of inexpensive plastic or other rigid substrate.

  • Publication number: 20080097229
    Abstract: Early treatment for a degenerated disc includes identifying a non-ruptured, dehydrated disc. A hygroscopic agent is then selected. This agent should pull water towards itself and have a hygroscopic compound with a molecular weight of at least 400 Daltons. Additionally, it may be desirable to selected hygroscopic compounds that are anionic or electrically neutral. The hygroscopic agent is then injected into the nucleus pulposus of the disc without any prior removal of the nucleus pulposus material. Because the surrounding disc structure allows for the passive diffusion of water into the nucleus pulposus, the hygroscopic agent will draw water into the nucleus pulposus, thus promoting tissue hydration within the disc. The hygroscopic agent may also include a biological agent and/or an imaging agent.

  • Publication number: 20080097233
    Abstract: The invention relates to a method and an apparatus for estimating a PaCO2 value for a patient subject to extracorporeal circulation by means of an oxygenator. The method comprises the steps of measuring a PexCO2 value in the exhaust gas of the oxygenator and the patient's arterial blood temperature value Ta, using a temperature sensor arranged in the oxygenator. The estimated PaCO2 value is then calculated, based on the measured PexCO2 value and the arterial temperature measurement. Advantageously, an average value determined from a predetermined number of recent PexCO2 values is used in the calculation. The calculation is performed by adding a correction term to the PexCO2 value, which is composed of a temperature dependent component and an offset component. The correction term may be adjusted by a user. The estimated PaCO2 value is presented on a display. A switch provides easy alteration between pH-stat mode and alpha-stat mode.

  • Publication number: 20080097243
    Abstract: Some embodiments of the invention provide a needle with a sharp open end and a blunt open end, housed in a barrel with an open anterior end and an open posterior end. The barrel can travel along the hub of the needle, for extending the needle for insertion into a blood vessel, and for retracting the needle into the barrel to avoid injury. The blunt open end can be fluidly connected to the inlet opening of a measurement apparatus, so that the blood can flow directly into the measurement apparatus, eliminating the traditional step of transferring the blood from a syringe to the measurement apparatus. The hollow needle assembly can remain attached to the measurement apparatus because of its small size, and the engagement of an optional safety cap to the open anterior end of the barrel, minimizes the risk of injury and blood contamination. Because a small blood sample is required, a very small needle shaft can be used, minimizing the discomfort experienced by the patient.

  • Publication number: 20080097258
    Abstract: Methods to control the delivery of CPR to a patient through a mechanical CPR device are described. The method generally allows for a gradual increase in the frequency of CPR cycles. The gradual increase can be regulated by protocols programmed within the CPR device such as intermittently starting and stopping the delivery of CPR, accelerating the delivery of CPR, stepping up the CPR frequency, increasing the force of CPR, and adjusting the ratio of compression and decompression in a CPR cycle. Combinations of each of these forms may also be used to control the delivery of CPR. This manner of gradually accelerating artificial blood flow during the first minutes of mechanical CPR delivery can serve to lessen the potential for ischemia/reperfusion injury in the patient who receives mechanical CPR treatment.
