摘要： An intravascular safety guidewire including an elongated main shaft, a distal terminus extending from the elongated main shaft, and an anchor rotatably connected to the distal terminus. In use, a needle is inserted into a patient's vein, then the intravascular safety guidewire is placed through the needle and into the vein, the needle is then removed over the intravascular safety guidewire, then a venous catheter is exchanged over the intravascular safety guidewire following serial dilatation using the Seldinger technique. Tubes such as dilators and catheters can then be placed over the intravascular safety guidewire and the intravascular safety guidewire ultimately removed. Currently complications can arise if a guidewire becomes retained inside a patient during an endovascular procedure, which is associated with high morbidity and mortality rates. The instant intravascular safety guidewire with its rotatable anchor reduces the likelihood of this complication.

摘要： A delivery sheath is provided that that can be used to deliver a therapeutic device to the heart without dislodging the device when the delivery sheath is removed. The delivery sheath comprises a tubular body having a proximal end, a distal end, and a lumen. The therapeutic device is delivered through the lumen. A slit is provided along the length of the tubular body creating two opposing edges along the length of the tubular body. A guide wire engages along an entire length of the slit and closing the two opposing edges to form the lumen. The slit is opened from the distal end of the tubular body toward the proximal end of the tubular body by pulling on the guide wire at the proximal end, whereby the lumen expands and separates from the therapeutic device facilitating the extraction of the delivery sheath without disruption to the implanted device.

摘要： A guidewire includes a wire body having a first wire arranged on a distal end side and a second wire arranged on a proximal end side of the first wire. A proximal end surface of the first wire and a distal end surface of the second wire are joined to each other to form a joint portion. An outer member is arranged on an outer peripheral side of the wire body and forms a tubular shape which covers the wire body at least from a distal end portion of the first wire to the joint portion. An inner member is arranged between an outer peripheral portion of the wire body and an inner peripheral portion of the outer member and covers the joint portion. The inner member is an inner coil formed by winding a wire for the inner member into a coil shape.

摘要： A coil structure used in an endoscope includes a coil tube formed by densely winding a wire rod, both ends of the coil tube being fixed, a first contact surface formed on one surface of the wire rod on a distal end side, and a second contact surface formed on the other surface of the wire rod on a proximal end side, the first contact surface coming into contact with the second contact surface. The first contact surface is formed as a convex curved surface arcuate in cross section, a curvature center of which is located further on an inner side than an outer circumferential portion of the coil tube. For the convex curved surface, a curvature radius larger than a radius of the coil tube and smaller than a curvature radius during maximum bending of an insertion section is set.
