  • Patent number: 10485631
    Abstract: The length of an optical fiber from a portion aligned with the rear end of an insertion needle to a fixing portion is a length obtained by adding a predetermined extra length to a linear distance between the rear end of the insertion needle in a case where the insertion needle is located at a protruding position (insertion position) and an optical fiber fixing position of a grip portion. There is provided a fiber feeding adjustment mechanism that suspends the optical fiber with a first suspension portion and a second suspension portion so as to make a detour in a state in which there is no slack, and changes the detour length continuously according to the movement of the insertion needle in a case where the insertion needle moves between the retracted position and the protruding position, thereby maintaining a state in which the optical fiber is suspended without slack.

    Abstract: Drug delivery devices and methods are disclosed herein. In some embodiments, a drug can be delivered into a brain ventricle of a subject, where it can diffuse, flow, or otherwise travel across the ependyma and into the hippocampus. The drug can be delivered through a delivery device configured to selectively or transiently obstruct a portion of the ventricle, e.g., the temporal horn or a posterior portion of the temporal horn. The obstruction can define a partitioned volume of the ventricle, limiting or preventing flow of cerebrospinal fluid (CSF) into or out of the partitioned volume. Accordingly, a drug can be delivered into the partitioned volume without being diluted or carried away by CSF, allowing the drug to saturate the ependyma adjacent the hippocampus.

The apparatus responds to a change in pressure, force, or other parameter such that when the tip reaches matter of a certain resistance, a change in the parameter is sensed. The apparatus provides a driving force to a penetrating medical device, such as a needle, when the apparatus tip encounters material of high resistance. When the apparatus tip encounters a low resistance material, no further driving force is applied to the apparatus. An inner core may be advanced into the low resistance material for deployment of a gas or a liquid as desired.

  • Patent number: 9364646
    Abstract: Tools for determining and adjusting the setting of an adjustable valve are disclosed. These tools allow a medical professional to locate and non-invasively determine the setting of an implanted valve. After the valve has been located and the setting of the valve determined, the valve may be re-adjusted non-invasively. There are three tools: a locator tool, an indicator tool and an adjustment tool. The locator tool allows the physician to locate the adjustable valve of interest and align the locator tool with a specific orientation of the valve. The indicator tool indicates the current setting of the adjustable valve and confirms new settings of the valve after the new settings have been implemented. The adjustment tool interacts magnetically with the implanted adjustable valve to couple with a movable internal element to change the setting of the valve. The indicator tool and the adjustment tool physically cooperate with the locator tool to accomplish the respective functions of the tools.

  • Patent number: 9204812
    Abstract: Devices and methods useful for sensing or measuring a pressure and remotely indicating or communicating that pressure are provided. The devices and methods have particular utility in sensing pressures in implantable medical devices and more particularly in hydrocephalus shunts. In one exemplary embodiment, an implantable valve can include a housing having a reservoir adapted to receive fluid flow therethrough between an inlet port and an outlet port. The implantable valve can also include a needle-penetrable septum to allow fluid delivery to the reservoir and/or a needle guard disposed within the housing and adapted to protect the radio frequency tag from a needle penetrating into the housing. A radio frequency (RF) tag can be disposed within the reservoir and can be adapted to change one or more of its electromagnetic characteristics in response pressure applied thereto by fluid in or flowing through the reservoir.

  • Patent number: 9168023
    Abstract: A method and apparatus for continuously measuring the absolute intracranial pressure in a non-invasive manner is described by using an ultrasonic Doppler device which detects the pulsatility indexes of the blood flow inside the eye artery for both intracranial and extracranial eye artery portions. The eye in which the blood flow is monitored is subjected to a small pressure, sufficient to equalize the pulsatility index measurements of the internal and external portions of the eye artery. The pressure at which such equalization occurs is used as a reference for autocalibration of the apparatus so that continuous absolute intracranial pressure measurements may be taken over a particular sampling period.

  • Patent number: 9044614
    Abstract: A successive approximation ADC made of a low voltage configurable differential amplifier and low voltage logic circuits which can convert a high voltage analog input to a digital equivalent. The differential amplifier can be configured as either an op amp or a comparator depending upon the mode of operation. An input capacitor C1 is switchably coupled to an electrode selected for voltage sampling. A switched capacitor array C2 is coupled across the differential amplifier input and output. A SAR coupled to the switched capacitor array provides a digital output corresponding to the sampled analog voltage. During a sampling interval and a charge transfer interval, the differential amplifier is configured as an op amp. During the transfer interval, the voltage on the input capacitor multiplied by the ratio C1/C2 is transferred to the switched capacitor array. During an analog to digital conversion interval, the ADC converts the analog voltage to an equivalent digital output.
