A catheter and guide wire assembly (10) for measurement of blood pressure in a living body, comprising: a proximal tube (11) having a distal end and a proximal end; a distal tube (12) having a distal end and a proximal end, which is connected to the distal end of the proximal tube (11); a fluid-permeable coil (13) having a distal end and a proximal end, which is connected to the distal end of the distal tube (12); a distal tip (14), in which the distal end of the fluid-permeable coil (13) is secured; and a core wire (16), which is attached in the proximal tube (11) and which extends through a portion of the proximal tube (11), the distal tube (12) and the fluid-permeable coil (13), and is secured in the distal tip (14), wherein the distal end of the proximal tube (11) and the proximal end of the distal tube (12) are connected by a butt joint and wherein the core wire (16) is glued or brazed to the inner wall of the proximal tube (11) at or close to the butt joint.

A coil winding apparatus includes: a core rod feeding unit configured to feed a string-shaped core rod from a core rod nozzle; a core rod drawing unit configured to draw out the core rod; a wire rod feeding unit configured to feed a wire rod towards the core rod; a rotator capable of rotating about the core rod nozzle; the guide member provided on the rotator, the guide member being configured to clamp, with the core rod, the wire rod that has been fed from the wire rod feeding unit; and a rotating unit configured to rotate the rotator to rotate the guide member together with the rotator so as to revolve the wire rod around the core rod in a vicinity of the core rod nozzle.

A method for forming a desired bend angle in an orthodontic appliance comprising: monitoring bending of the orthodontic appliance in a gripped state, the monitoring being continuous; in response to an initial bend angle in the orthodontic appliance in the gripped state being reached, causing the release of at least a portion of the orthodontic appliance so that orthodontic appliance is in a free state, measuring resultant angle of the bend in the free state; in response to resultant angle being within a predefined tolerance of the desired bend angle, determining that desired bend angle has been reached.

An occlusive device, occlusive device delivery system, method of using, and method of delivering an occlusive device, and method of making an occlusive device to treat various intravascular conditions is described.

A wire feeding and bonding tool and method for attaching wires to a component having first and second spaced-apart wire attach structures. Wire from a supply is fed through a capillary having at least a linear end portion with a feed opening. The capillary is positioned with respect to the component to locate a first portion of the wire extending from the feed opening adjacent to the first wire attach structure, and the wire is attached to the first attach structure. The capillary is moved with respect to the component along a wire feed path to feed the wire from the first wire attach structure to the second wire attach structure and to locate a second portion of the wire extending from the feed opening adjacent to the second attach structure. The wire is attached to the second wire attach structure, and cut from the supply.

Cutting devices useful for cutting objects or materials are described. Examples of cutting devices useful for creating avulsions in animals, such as human beings, are described. A cutting device includes an elongate main body having proximal and distal ends. A first portion of the main body has a cross-sectional shape that substantially lacks flat surfaces and a second portion of the main body has a cross-sectional shape having one, two or more flat surfaces. The distal end defines a hook having one or more sharpened edges disposed within the notch of the hook. Methods of making cutting devices are also described.
