    摘要： A tunneling device, which is implantable in a body, includes a flexible covering to protect a medical from contamination during the handling and implantation of the device in the body. The tunneling device of the present invention may optionally include a rigid tunneler tip that allows for attachment of the tunneling device to a tunneler instrument prior to the implantation process.

    摘要： Systems and methods for positioning a wire for advancement through a vessel wall, and advancing it through one or more vessel walls, generally include a delivery catheter and an alignment catheter or a receiving catheter, and a guidewire. In some variations, the systems and methods may be used to bypass an occlusion or other barrier that may prevent advancement of a wire or tools through an endoluminal space. In these variations, the systems and methods include a delivery catheter, a bypass catheter, a receiving catheter, and a guidewire. The delivery and receiving catheters each generally include a side aperture, a deflection surface, and an alignment element, and the bypass catheter generally includes two side apertures, two deflectors, and two alignment elements. In some variations, the systems and methods may assist in treatment of a patient suffering from critical limb ischemia.

    摘要： Disclosed herein is a catheter apparatus for cranial cavities which exhibits the advantage of a conventional catheter structure in that a medicine and a bodily fluid are transferred along different paths, uniformizes the outer diameter of a catheter (30) to easily use stereotactic equipment, and facilitates tunneling of the rear end of the catheter (30) in a bypass space between the skull and the skin, so as to allow an operation to be simply and easily performed and thus to increase safety in operation. The catheter apparatus is advantageous in that no protrusion is formed on the outer surface of the catheter (30) so as to easily and accurately locate the end of the catheter (30) in a cerebral ventricle, the catheter (30) may be easily bent through the bypass space, and the rear end of the catheter (30) may be easily exposed to the outside through a perforated part.
