The current invention features a rod screw for medical application that can be configured and used to fixate fracture of bones varying in shape and dimension, and treating maladies such as scoliosis, and securing an implanted device, to tissue such as bone. This is achieved by designing a flexible rod screw with a mechanism to lock the configuration in a rigid state. In an embodiment, a bone-fracture fixation device, such as a rod screw, includes a flexible body, a plurality of flexible members, and first and second interfaces. The flexible members are disposed longitudinally within the flexible body, such that the flexible body is rigid when the flexible members are fixed into position. And the first and second interfaces are respectively coupled to the flexible body, each of at least one of the first and second interfaces including a respective at least one hole each configured to receive a respective attachment member configured to engage a bone.

An intramedullary nail system is provided with at least one resilient, elongate nail body configured to extend axially along a medullary bone cavity, and at least one bone anchor. The bone anchor includes a distal bone engagement portion configured to secure the anchor to a bone, a proximal nail engagement portion configured to receive a portion of the nail body therethrough, and a tightening mechanism configured to move from a movable state in which the nail body may slide axially and rotate through the engagement portion and a fixed state in which the nail body is prevented from moving relative to the engagement portion. Methods of use and surgical kits are also provided.

A surgical nail, such as an intramedullary nail, includes a nail body that includes a proximal end, an elongate intermediate portion comprising an intermediate flexible portion; and a distal end. The proximal end and the distal end are coupled and offset from one another by the elongate intermediate portion. The wherein the intermediate flexible portion comprises at least two cables boned one to another and configured to maintain a fixed length. The at least one cable comprises two or more cables twisted around one another in a helical arrangement and welded together. The proximal portion and the threaded end portion can be coupled together by the intermediate flexible portion as a unitary, integrated element prior to any use of the surgical nail in an implant procedure. The intermediate flexible portion is configured to permit the proximal portion to bend at an angle relative to the distal portion as a unitary, integrated element.

An intramedullary nail may include a shank with a centerline defined along a length thereof. The intramedullary nail may also include a channel with a channel axis transverse to the centerline. The channel may have an obround shape in a first cross-sectional plane perpendicular to the channel axis at the centerline and a tapered profile in a second cross-sectional plane containing the channel axis. A proximal edge of the channel within the second cross-sectional plane may form a first angle relative to the channel axis and a distal edge of the channel within the second cross-sectional plane may form a second angle relative to the channel axis that is different from the first angle.

The disclosure relates to medical devices and methods of manufacturing medical devices. An intramedullary rod includes a head member, a shaft member partially disposed within a distal recess of the head member, and an outer body member disposed circumferentially around the shaft member and a portion of the head member. Medical device systems and methods of manufacturing medical devices are also described.

Implantable devices for fixation of curved bone such as the pelvic ring pubic symphysis and acetabulum, and methods for the use of the devices are disclosed. The implantable devices are convertible between a flexible state and a rigid state, and include an elongate structure having a proximal bone interface, a main body, and a distal bone interface. In a flexible state, the devices may be inserted along, and conform to a curved pathway, and in the rigid state, the devices may support the mechanical loads required to fixate a fracture.

The invention consists in a product for the closed reduction and, more specifically, in a new type of an intramedullary cannulated guide for fracture reduction with an endoscopic camera for use in intramedullary nailing surgeries. The intramedullary cannulated guide for fracture reduction is consisted of a flexible, unbreakable, modular and cannulated shaft, a T-handle with a hole in the upper surface, a camera, which is located at the edge of the guide, bears a lightning source and is connected wired or wireless to an image reproduction device, a sealing flange with a slot or spout, an input/output cannula for liquid suction and/or washing of the camera glass. The intramedullary cannulated guide for fracture reduction with an endoscopic camera is inserted in a bone that has suffered a fracture. The intramedullary image that the camera transmits, when it encounters the fracture point, is shown on the screen. Thus, the surgeon perceives the direction towards which the bone parts have to be pushed, in order to achieve their reduction with skeletal manipulations. After the intramedullary cannulated guide for fracture reduction is inserted, the camera is removed from the guide, by pulling out the cable of the camera, and, through the canal of the guide, the ball tip guide wire is inserted and the surgery continues as it is conducted up until today.

An intramedullary affixing apparatus, comprising: a hollow shaft suitable for insertion into a bone and adapted to accommodate a proximal anchoring device, a transmission arrangement, and a distal anchoring device, wherein the hollow shaft comprises a proximal threaded actuator and a distal threaded actuator, wherein the threading-in of the proximal threaded actuator exerts a linear motion of the proximal anchoring device, the transmission arrangement, and the distal anchoring device towards the distal edge of the hollow shaft and the threading-in of the distal actuator exerts an opposite motion.

Implantable devices for fixation of curved bones such as the pelvic ring pubic symphysis and acetabulum, and methods for the use of the devices are disclosed. The implantable devices are convertible between a flexible state and a rigid state using a shape locking section. The implantable devices further include a main body and a distal bone interface. In a flexible state, the devices may be inserted along, and conform to a curved pathway, and in the rigid state, the devices may support the mechanical loads required to fixate a fracture.

Provided is a method of open reduction and internal fixation of a bone of a patient using a fixation device. The method includes analyzing the bone to obtain a fracture profile, wherein the fracture profile includes data corresponding to a physical structure of the bone, shaping the fixation device using the data of the fracture profile, heat treating the fixation device by heating the fixation device to a first temperature, cooling the fixation device to a second temperature lower than the first temperature, securing the fixation device to the bone, and heating the fixation device to a third temperature lower than the first temperature and greater than the second temperature to reduce the bone.
