  • Publication number: 20190183402
    Abstract: A system and method for detecting brain concussion includes detecting and measuring of acceleration at one or more points on a subject's head. Sensors, which can be accelerometers placed against the head, detect and measure natural motions of the patient's head due to blood flow in the brain and resultant movement of tissue in the brain. The acceleration data are then analyzed, including as to frequency of motions of the skull at the subject location in a frequency range of about 1 to 20 Hz. An observation is then made, as compared with data corresponding to non-concussion, of a change in frequency response pattern exhibited when accelerations are plotted as a function of time or frequency, to identify probable concussion if the frequency response pattern indicates concussion. Preferably the observation and comparison are made by a computer using an algorithm.

  • Patent number: 10307065
    Abstract: Cerebral vasospasm is detected in subarachnoid hemorrhage patients by use of highly sensitive accelerometers in contact with the head. Acceleration data can be investigated in the time domain, typically averaged over a number of heartbeats, to detect a drop in energy during diastole, and diastole/systole ratio can be compared with known data of normal and vasospastic patients. Data from one or more accelerometers can also be subjected to FFT and optionally plotted in a waterfall diagram, to observe the appearance of energy at higher frequencies as 50 Hz to 1000 Hz, also indicating vasospasm.

  • Patent number: 10092195
    Abstract: Vascular conditions are detected non-invasively in the human body using a collection of information from small local regions of the vasculature, or from a specific signature or “BrainPulse” that can be derived from a patient's heartbeat-induced cranium movements. An array of accelerometers or other sensors are engaged against the head of a patient and skull movements, preferably under 100 Hz, are recorded. Vibration signatures of vessel structures such as branches, aneurysms, stenosis, etc. using random, periodic, band limited or transient analysis provides a library for further processing. The signature library is used to localize the origin of the recognized vascular feature, and the localized feature is presented to the physician in a clinically relevant manner.

  • Patent number: 9055972
    Abstract: Attenuating masks for selective attenuation of radiation, particularly from an x-ray source in brachytherapy, employ materials having atomic number in a specific range, so as to attenuate radiation dose intensity generally proportionally through a range of distance from the source. Some preferred attenuation materials are silver and molybdenum. A set of small masks can be provided for a particular design of catheter that holds a radiation source, each mask having a size and shape to define a different solid angle of masking, so that in a brachytherapy procedure, sensitive tissue such as bone or skin can be protected by proper selection of and positioning of the attenuating mask, to reduce the dose intensity to that tissue.

  • Patent number: 8409070
    Abstract: Brachytherapy treatment of a patient's lung tissue following resection is effected using a balloon applicator which is inserted, normally through the same opening used for the surgery, through the chest wall and into the cavity. The lung and chest openings are closed around the applicator and generally sealed around the applicator. A suction port is provided, in a suction circuit of the applicator, to withdraw fluid from the pleural cavity, at intervals as needed, to assure that the lung can be inflated. Different embodiments of suction circuits are disclosed. A bronchial applicator and method are also disclosed.

  • Publication number: 20130041447
    Abstract: A cardiac pacemaker, other CRT device or neurostimulator has one or more fine wire leads. Formed of a glass, silica, sapphire or crystalline quartz fiber with a metal buffer cladding, a unipolar lead can have an outer diameter as small as about 300 microns or even smaller. The buffered fibers are extremely durable, can be bent through small radii and will not fatigue even from millions of iterations of flexing. Bipolar leads can include several conductors side by side within a glass/silica fiber, or can be concentric metal coatings in a structure including several fiber layers. An outer protective sheath of a flexible polymer material can be included.

  • Patent number: 8354658
    Abstract: A flexible, lightweight radiation absorbing sheet or shield includes heavy metal particles in one layer and mid-atomic number particles in another layer, the layer that will be adjacent to the patient. The shield is particularly intended for protection of the wearer and others from radiation emanating from a therapeutic source positioned within the patient's body. With the disclosed multi-layer shield construction, backscattered radiation off the heavy metal particle layer, affecting the patient's adjacent tissue, is minimized.

  • Patent number: 8262555
    Abstract: Radiation treatment methods for breast cancer following resection, both intraoperative and post operative, involve mapping preferably using an electronic x-ray source, and can include rotation of a direction source. By using a very rapid, near-instantaneous method of pathology of tissue margins following resection, the invention carries out intraoperative radiation treatment, preferably with the patient remaining anesthetized. Whether or not radiation is intraoperative, the invention preferably includes a mapping procedure using an electronic source that is progressed through the resection cavity while radiation dose is sensed at one or more points, to determine the shape of the resection cavity.

  • Publication number: 20120142992
    Abstract: In brachytherapy radiation treatment, particularly on the breast following a tumor resection, adequate skin to balloon distance must be maintained, to avoid damage to the skin. Often the distance is too small in certain areas or at a single point. The disclosed procedures and devices are effective to manipulate the skin-to-balloon distance to increase that distance when necessary, using vacuum, friction or other means to grip, move and “bunch” the breast tissue from regions of larger balloon-skin distance to regions with inadequate balloon-skin distance. The apparatus can include a ring or ring shaped array that fits around the breast, larger than the balloon, a circular vacuum device, or a cup which is pushed over the breast to move tissue toward a thin tissue region. In many cases only a few millimeters of added distance are needed to meet minimum requirements so that the radiation procedure can commence.
