An active cannula which does more than merely maintain a passage is usable to create and / or enlarge a passage, to position a scope or instrument, to move or locate tissue, etc. The cannula can vary in size or shape as needed, intraoperatively. Because a cannula of the present invention is expandable, the surgeon can make a relatively small incision, stretch the tissue with the expandable cannula, contract the cannula and remove it, allowing the skin to come back to its unstretched condition. Thus, a smaller incision can be made to fit the same size instrument. The cannulas can assume such a non-circular shape, to fit into a natural skin opening and cause less trauma. The devices can be used to seal off a space, expand an existing space or a potential space for working or visualization, move tissue (for example, to stretch an incision), or protect tissue.

The present invention discloses a human body affinitive lubricating protective and repair gel, which combines photocatalyst (TiO2) particles with a disinfection material such as nano silver to produce a TiO2Ag compound, and mixes the compound with a filtered natural biological organism with a molecular weight below 50 Kbp and a concentration of 0.05˜5% including small molecules of collagen, chitin, chitosan, hyaluronic acid, vitamin C, and nano iron, and its pH value is adjusted to 6 which is close to the pH value of our skin, and thus the mixture constitutes a gel affinitive to human skins and non-toxic to human cells. An accessory ingredient such as an aromatic agent, a detergent, or a cosmetic agent is added in the manufacturing process to produce an emulsion or a paste for coating or spraying, which is used as a health or sanitation item such as a hand liquid soap, a cosmetic, a shampoo, or a disinfectant. The feature of the small diameter of the particles (1˜100 n / m) can penetrate the cuticle of our skin and remain at the derma inside the skin pores to produce a protective film, and the collagen can be absorbed by the skin to give the effects of repairing tissues, stopping bleeding, and lubricating skins. With the cyclic disinfection effect of the TiO2Ag compound, a deeper clean skin to prevent germs is obtained and a disinfection effect is achieved to eliminate acnes and pimples. The present invention also makes use of an oxidation-reduction mechanism of the photocatalyst (TiO2) to achieve long-hour disinfection and naturally remove germs.

A method to stop bleeding at a puncture site of an artery on a wrist of a patient comprises wrapping a flexible band of a hemostatic device around the wrist of the patient, wherein the hemostatic device also includes a curved plate, a balloon and a marker used to position the balloon at the puncture site, and wherein the flexible band, the curved plate and the balloon are substantially transparent. The wrapping of the flexible band around the wrist of the patient involves wrapping the flexible band around the wrist of the patient while the balloon is in an uninflated state. The wrapping can also take place while an introducer sheath is in place at the puncture site. The method also involves using the marker to position balloon relative to the puncture site such that the balloon overlies the puncture site, introducing a fluid into the balloon and inflating the balloon, and maintaining inflation of the balloon and compression against the puncture site.

Diseases and disorders of dermal tissue such as the skin, hair and nails are treated or prevented by administering one or more lectins, capable of binding to the surface of pathogenic microorganisms inhabiting the hair, skin, and nails, or of binding to the superficial tissues that comprise hair, skin, and nails. The lectins may be administered topically or subcutaneously to a patient infected with pathogenic microorganisms or in danger of being exposed to such pathogens. Lectins that stimulate cell mitosis may also be administered to accelerate wound healing and restore the appearance of age-wrinkled skin. Lectins that coagulate blood can be administered to assist in stopping bleeding from skin lesions. The lectins may be applied to the skin in a pharmceutically acceptable vehicle.

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.

An AV fistula between first and second blood vessels is created by forming a hole through adjacent walls of the vessels and inserting a welding catheter into the first vessel, and through the hole into the second vessel, so that a distal end of the catheter is disposed within the second vessel. A portion of wall defining the welding catheter is then expanded radially outwardly, and the expanded wall portion is pulled proximally to engage the wall of the second blood vessel and to pull it toward the wall of the first blood vessel. A portion of wall proximal to the first expanded wall portion and disposed in the first blood vessel is expanded radially outwardly, thereby capturing the walls of each of the second and first blood vessels between the two expanded wall portions. Cutting elements are energized to create a tissue welded elongate aperture between the blood vessels.
