Endodontic instruments for use in performing root canal therapy on a tooth are disclosed. In one form, the instruments include an elongate shank having a cutting edge extending from a distal end of the shank along an axial length of the shank. The shank comprises a titanium alloy, and the shank is prepared by heat-treating the shank at a temperature above 25° C. in an atmosphere consisting essentially of a gas unreactive with the shank. In another form, the endodontic instruments have an elongate shank having a cutting edge extending from a distal end of the shank along an axial length of the shank. The shank consists essentially of a titanium alloy selected from alpha-titanium alloys, beta-titanium alloys, and alpha-beta-titanium alloys. The instruments solve the problems encountered when cleaning and enlarging a curved root canal.

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 method is provided for determining the shape of a surgical linking device that is to be attached to a bony body structure such as the spinal column based on digitized locations of a plurality of attachment elements engaged to the bony structure. The method is implemented by a computer system through a GUI to generate an initial bend curve to mate with the plurality of attachment elements. The initial bend curve may be simplified based on user input to the GUI to reduce the number of bends necessary to produce a well-fitting linking device and may be altered to help obtain the goals of surgery.

Systems providing robotic bending used to bend a surgical rod are disclosed. Such systems may include a processor and memory coupled with the processor. The memory includes computer readable program code so that when the computer readable program code is executed by the processor, the processor performs operations including providing a set of transformation points corresponding to respective attachment implants, generating a bend plan for the surgical rod based on the set of transformation points, and generating an image output to render the set of transformation points and the bend plan on a display. Related methods and computer program products are also discussed.

A cerebral aneurysm stent (1) of the present invention comprises a hollow tubular main body (10) and a coil support (20) integrally formed with the main body (10) at one end of the main body (10) in the longitudinal direction, wherein the coil support (20) comprises a closed structure (21) with respect to the radially inner side of the cerebral aneurysm stent (1), the closed structure (21) being located at an outer end portion of the cerebral aneurysm stent (1) in the longitudinal direction.

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.

System and method for automatically bending a surgical rod are provided. The system includes a linear movement device configured to axially feed the surgical rod, a rotational movement device configured to rotate the surgical rod as it is axially fed, and a bending device including a roller to impose bending forces against the rod. The rod is free from contact with the bending device after it is axially fed past the roller.

A stent for repairing post-anastomasis (e.g., bariatric) surgery leaks is formed by an elongated tube having a proximal flare-shaped flange, an enlarged middle section, and a distal flare-shaped flange, where an exterior surface of the elongated tube is substantially covered with a polymer.

A method of making a medical guidewire including providing a wire having a length that includes a proximal length and a distal length. The method further includes applying cold work to the distal length and not applying cold work to the proximal length, thereby imparting to the distal length a diameter that is smaller than the proximal length diameter; and applying a reducing process to the wire whereby the proximal length is reduced to have an outer diameter that is the same as the outer diameter of the distal length. The proximal length has an inner diameter and the distal length has an inner diameter that is less than the inner diameter of the proximal length.

A stent and a method for manufacturing the stent are disclosed. A stent according to an embodiment of the present invention is manufactured by using a jig having a cylindrical body on which a plurality of pins (P) are arranged in the circumferential direction (X) and the lengthwise direction (Y). The stent has a cylindrical structure, in which a wire member forms a zigzag pattern woven in the circumferential direction (X) with a predetermined width through the pins on the jig and a plurality of zigzag patterns formed in the circumferential direction (X), intersecting with one another, are arranged in the lengthwise direction with predetermined intervals (W) therebetween, forming a mesh structure with a rhombus pattern.
