A stent is disclosed that has an elongated body composed of a bioabsorbable polymer having a proximal end, a distal end, two open spiral channels formed on the exterior surface of the body to provide fluid communication between the proximal end and the distal end. The stent also has a central lumen open at the proximal and distal ends of the stent for the passage of a guide wire. A method for using the stent and a kit containing the stent are also disclosed.

Intramedullary systems, expandable intramedullary nails, expandable anchors, and methods of using the same. The intramedullary system may include an expandable intramedullary nail configured to extend into an intramedullary canal of a long bone and/or one or more expandable anchors configured to extend at an angle transverse to the intramedullary nail. The intramedullary nails and/or anchors may include one or more integrated expansion mechanisms that allow for insertion in a contracted configuration and expansion into a deployed configuration to lock the relative position and prevent axial rotation and translation of the system.

An example apparatus is provided for bone fixation. The apparatus may include a nail, a suture lock, a tightening device, and a suture. The nail may include a proximal end and a distal end, with the suture lock being disposed at the proximal end of the nail. The suture may extend at least between the suture lock and the tightening device. Actuating the tightening device may transition the suture lock from an unlocked position to a locked position.

A device (200) for actuating an intramedullary nail (1) is proposed, which extends in the axial longitudinal direction (L) and comprises a proximal end (202) and a distal end (204), and comprises an actuating shaft (300, 600) which is associated with an actuating element (400, 700), and which comprises at its distal end (304, 604) an engagement section (306, 606) for engaging in, and rotating or retaining, a counterpart complementary thereto, wherein an adapter piece (500, 800) is arranged between the distal end (304, 604) of the actuating shaft (300, 600) and the distal end (204) of the device (200), which adapter piece (500, 800) is connected in a rotatably fixed manner to the engagement section (306, 606) of the actuating shaft (300, 600) at the distal end (304, 604) of the actuating shaft (300, 600), and which comprises, at the distal end (204) of the device (200), an engagement section (506, 806), which is complementary to an engagement section (32, 1032) of the anchor element (24, 1024) of an oppositely arrangeable intramedullary nail (1). Furthermore, the invention relates to an adapter piece (500, 800) and an adapter set, as well as a set for providing a device (200) according to the invention.

Systems for treating and/or preventing fractures include at least one needle sized and configured to be placed into target bone and at least one implantable pin configured to be releasably held in a first needle of the at least one needle. The systems also include at least one delivery device of injectable material configured to couple to the first needle while the first implantable pin is held in the first needle whereby the at least one delivery device and a respective needle cooperate to serially provide an external column of the injectable material about the at least one implantable pin.

A stent is disclosed that has an elongated body composed of a bioabsorbable polymer having a proximal end, a distal end, two open spiral channels formed on the exterior surface of the body to provide fluid communication between the proximal end and the distal end. The stent also has a central lumen open at the proximal and distal ends of the stent for the passage of a guide wire. A method for using the stent and a kit containing the stent are also disclosed.

An example apparatus is provided for the approximation of two bones. The apparatus can include a nail configured to be disposed within a first bone (e.g., the fibula). The nail can include a proximal end, a distal end, and a rigid body. The apparatus can further include one or more first threads disposed along the proximal end of the nail, and one or more second threads disposed along the distal end of the nail. The first thread(s) can be axially spaced from the second thread(s).

The invention relates to an intramedullary nail (1) for transverse distraction of a tubular bone (2), the intramedullary nail (1) comprising an at least partially hollow tube body (3) extending in an axial direction of the intramedullary nail (1), at least one locking means for locking the tube body (3) in an end portion of the tubular bone (2), a first inner part (5) and a second inner part (7), which are each arranged within the tube body (3) so as to be displaceable in the axial direction toward each other or with each other, a drive within the tube body (3) for axial displacement of the first inner part (5) relative to the second inner part (7), at least one longitudinal recess (11) in the tube body (3), and at least one lever mechanism (20) which comprises at least one lever element (9, 23, 24) which is designed to be extended out of, and to be retracted again into, the tube body (3) in a radial direction, wherein the displacement of the first inner part (5) relative to the second inner part (7) causes the at least one lever element (9) to be moved or extended out of the at least one lateral longitudinal recess (11) in the tube body (3) or causes the at least one lever element (9) to be moved or retracted into the at least one lateral longitudinal recess (11) in the tube body (3).

Photodynamic devices for replacement of an articular head of a bone are provided. In an embodiment, a photodynamic device includes a photodynamic support member and an articular member attachable, either fixedly or removably, to the photodynamic support member and having a bearing surface. In an embodiment, the articular member includes a recess designed to receive the photodynamic support member. In an embodiment, the photodynamic support member includes an opening into which a shaft of the articular member can be inserted to attach the articular member to the photodynamic support member.
