A device for protecting cerebral vessels or brain tissue during treatment of a carotid vessel includes a catheter having a distal portion, a proximal portion and a lumen extending therebetween, the catheter including first and second expandable areas for vessel occlusion provided over the length of the catheter. The device further includes an elongate stretching member insertable longitudinally through the lumen of the catheter, the elongate stretching member being configured for stretching at least a portion of the catheter and causing the first and second expandable areas to transition from an expanded state to a collapsed state, and wherein the elongate stretching member is retracted proximally relative to the catheter causes the first and second expandable areas to transition from the collapsed state to a radially, or laterally expanded state.

Apparatus and method for making and using devices that generate optical signals, and optionally also electrical signals in combination with one or more such optical signals, to stimulate (i.e., trigger) and / or simulate a sensory-nerve signal in nerve and / or brain tissue of a living animal (e.g., a human), for example to treat nerve damage in the peripheral nervous system (PNS) or the central nervous system (CNS) and provide sensations to stimulate and / or simulate “sensory” signals in nerves and / or brain tissue of a living animal (e.g., a human) to treat other sensory deficiencies (e.g., touch, feel, balance, visual, taste, or olfactory) and provide sensations related to those sensory deficiencies, and / or to stimulate (i.e., trigger) and / or simulate a motor-nerve signal in nerve and / or brain tissue of a living animal (e.g., a human), for example to control a muscle or a robotic prosthesis.

An apparatus and method for detecting radiation damage in an area of brain tissues, where the area of brain tissues has at least a first region containing brain tissues damaged from radiation exposure and a second region containing no brain tissues damaged from radiation exposure. In one embodiment, the method includes the steps of illuminating in vivo the area of brain tissues with a coherent light at an incident wavelength, lambda0, between 330 nm and 360 nm, collecting electromagnetic emission returned from the illuminated brain tissues, and identifying a first peak of intensity of the collected electromagnetic emission at a first wavelength, lambda1, and a second peak of intensity of the collected electromagnetic emission at a second wavelength, lambda2, wherein lambda0, lambda1, and lambda2 satisfy the following relationship of lambda1>lambda2>lambda0. The method further includes the step of locating the first region containing brain tissues damaged from radiation exposure as the region of brain tissues where the first peak of intensity of the collected electromagnetic emission is corresponding to.

The present invention relates generally to a device and method for treating tissues of the central nervous system and more particularly, but not exclusively, to a device and method for treating the brain tissue.

The invention discloses an implanted type flexible sensor based on an organic transistor. The implanted type flexible sensor comprises a substrate support layer, a left metal source electrode, a right metal leakage electrode, an insulating layer, an organic conductive polymer active layer, and a sheath structure, wherein the left metal source electrode is manufactured on one side in the middle of the surface of the substrate support layer; the right metal leakage electrode is manufactured on the other side of the middle of the surface of the substrate support layer and is spaced for a certain distance from the metal source electrode; the insulating layer is manufactured above the substrate support layer and above the left metal source electrode and the right metal leakage electrode; a disconnection window is formed in the middle of the insulating layer; the organic conductive polymer active layer is manufactured inside the opened window of the insulating layer and covers the left metal source electrode and the right metal leakage electrode; the conductive polymer active layer is sensitive to ion concentration caused by electric physiological activity; the sheath structure is used for promoting implanting the sensor into target tissue; and the sheath structure is manufactured above the opened side of the insulating layer. As the sheath structure is used for promoting implanting the whole flexible sensor into a deep part of brain tissue, single nerve cell signals can be conveniently recorded.

Provided herein are compounds and compositions which comprise the formulae as disclosed herein, wherein the compound is an amyloid binding compound. An amyloid binding compound according to the invention may be administered to a patient in amounts suitable for in vivo imaging of amyloid deposits, and distinguish between neurological tissue with amyloid deposits and normal neurological tissue. Amyloid probes of the invention may be used to detect and quantitate amyloid deposits in diseases including, for example, Down's syndrome, familial Alzheimer's Disease. In another embodiment, the compounds may be used in the treatment or prophylaxis of neurodegenerative disorders. Also provided herein are methods of allowing the compound to distribute into the brain tissue, and imaging the brain tissue, wherein an increase in binding of the compound to the brain tissue compared to a normal control level of binding indicates that the mammal is suffering from or is at risk of developing a neurodegenerative disease.

The present invention relates to a method and device for removing solid matter from a brain and controlling bleeding associated with the removal of the matter. The method involves securing a cranial anchor to a region of the skull in which an opening has been created to expose brain matter and introducing through a passage defined by the anchor a channel member that displaces brain tissue and exposes the solid matter. After removing the solid matter, a flowable hemostat is introduced into the cavity created by removal of the matter. A balloon introduced into the working channel is then inflated to compress the hemostat against the wall of the cavity to control bleeding from blood vessels around the cavity. The device includes a cranial anchor, a channel member defining a working channel, an optional removable trocar, and a catheter for introducing the hemostat and the inflatable balloon into the cavity.
