Disclosed is a blood debris deflector, for preventing embolization during a surgical procedure, and methods for insertion and removal of the deflector. The method can include the steps of advancing an embolic deflection device through a first side branch vessel and into the main vessel, manipulating the deflection device such that it covers the opening to a second side branch vessel, and inverting the deflection device to remove the device from a patient.

A system, apparatus and methods are provided for extra-corporeal blood treatment, and in particular for establishing and maintaining a neck down differential body temperature, while maintaining near normal brain temperatures, to protect the brain from extended or extreme hypothermia or hyperthermia. A blood treatment apparatus and system is provided for differential control of brain temperature and body temperature below the neck. For example, a first bypass circuit with heat exchanger for brain blood circulation maintains a near normal blood temperature, while a second bypass circuit for below the neck blood circulation provides for thermal treatment to induce a temperature differential, e.g. hyperthermia or hypothermia, relative to brain circulation. Such systems and apparatus have application, for example, for diagnostic and therapeutic treatments using hyperthermia, particularly for treatments of extended duration or at elevated temperatures above 42° C., for example, hyperthermia for treatment of cancer, infectious bacterial or viral diseases.

A medical device having a catheter and one or more expandable constricting / occluding members. The catheter is adapted for use with therapeutic or diagnostic devices, including an angioplasty / stent catheter and an atherectomy catheter. A first constrictor / occluder mounted at the distal end of the catheter is adapted for placement in a brachiocephalic or subclavian artery. A second constrictor mounted proximal to the first constrictor / occluder is adapted for placement in the descending aorta. Pressure measuring devices may be included, and filters may be used to capture embolic debris. Methods of using the devices for preventing distal embolization during extracranial or intracranial carotid procedures or vertebral artery procedures by augmenting collateral cerebral circulation by coarctation of the aorta to enhance reversal of blood flow in an internal carotid artery, an external carotid artery, and / or a common carotid artery toward the subclavian artery are disclosed.

The invention relates to a Chinese medicinal preparation for treating chronic cerebral circulation insufficiency. The Chinese medicinal preparation is prepared from the following traditional Chinese medicines: 30 grams of astragalus, 15 grams of kudzuvine root, 15 grams of Chinese taxillus twig, 30 grams of root of red-rooted salvia, 9 grams of raw fructus crataegi, 9 grams of szechuan lovage rhizome, 10 grams of cassia twig, 12 grams of dwarf lilyturf root, 6 grams of Chinese magnoliavine fruit and 15 grams of fried date kernel. A preparation method of the Chinese medicinal preparation comprises the following steps of: adding 1,000 ml of water into the Chinese medicinal herbs subjected to processing for decocting; concentrating the decoction to 200 ml; and extracting residues and filtering to obtain a decoction. The Chinese medicinal preparation is taken once every day, and each treatment course lasts for two weeks. The Chinese medicinal preparation has the effects of replenishing qi, enriching the blood, relaxing muscles and joints, activating the channels, remarkably improving heart and brain circulation, enhancing mechanism immunity, resisting inflammation, delaying senility, treating both principal and secondary aspects of a disease, and the like, has reasonable compatibility, and can be used for effectively relieving symptoms such as dizziness, head heaviness, headache, dysphoria, tinnitus, irritability, insomnia, dreaminess, hypomnesia, inattention, fatigue, and the like of a patient suffering from chronic cerebral circulation insufficiency.

The invention discloses application of a Tibetan medicinal composition to the preparation of a medicament for treating cerebral circulation insufficiency. The Tibetan medicinal composition consists of the following raw material medicaments in part by weight: 5 to 15 parts of lamiophlomis, 2 to 10 parts of whin, 15 to 60 parts of turmeric, 7 to 20 parts of pepper, 5 to 15 parts of buffalo horn, 15to 40 parts of myricariagermanica, 0.1 to 2.5 parts of safflower, 0.1 to 5 parts of borneol and 0.1 to 5 parts of camphor. Further research on the pharmacology of the conventional Tibetan medicinal composition indicates that the Tibetan medicinal composition has good curative effect on cerebral circulation insufficiency. Moreover, natural wild medicinal materials from the Tibet Plateau are adopted and no chemically-synthesized stabilizing agent is added, so that the Tibetan medicinal composition has no toxic or side effect on a human body, is safe and effective and is suitable for all kinds of people and for treating various types of cerebral circulation insufficiency.

The invention discloses a medicament for treating the chronic cerebral circulation insufficiency and a preparation method. The medicament comprises salvia, codonopsis, coptis, chuanxiong, zedoary, crataegus, seaweed, gastrodia, coix seed and curcuma as raw materials. The preparation method comprises the following steps of: adding water to the coptis for decoction, concentrating the water decoction into thick paste, adding water to other raw materials for decoction, concentrating the water decoction into thick paste, combing the two pieces of thick paste, adding a suitable amount of dextrin, and uniformly mixing, drying, crushing and pelletizing the mixture. The medicament has the effects of simultaneously removing blood stasis, promoting blood circulation, eliminating phlegm and invigorating spleen, can better treat the arteriosclerosis, remarkably improve the integral of syndrome of intermingled phlegm and blood stasis for the granule fraction of removing blood stasis and promoting blood circulation, has better effects of reducing the whole blood high-shear viscosity, low-shear viscosity, plasma viscosity and platelet aggregation ratio, and has the advantages of high safety and no influence on hemogram, liver and kidney functions and the like.
