A system for manipulating a rotational device using a flexible guide rod with an external rod feature along its length to engage a rotational device with a complementary interior channel feature along its length. A driver having a handle and coupling element is coupled to the rotational device while the flexible guide rod extends from the handle, through the coupling element, and into the interior channel of the rotational device in order to rotate from within along the length of the device.

The present application provides a new and innovative device for aiding in screw installation through a distal end of a nail installed in a patient's bone (e.g., humerus). The nail's distal end is disposed away from an insertion point of the nail into the bone. The targeting device includes a targeting body having an outer frame, a flexible member connected to the outer frame, a targeting block having multiple holes and connected to the flexible member such that the flexibility of the flexible member enables the targeting block to translate towards sides of the outer frame, and an adjustment assembly that adjusts and maintains the targeting block's position relative to the sides of the outer frame. The targeting device further includes a base plate removably coupled to the targeting body. The targeting device may be coupled to the nail at the base plate.

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 implant includes a body including a substrate and a bone interfacing lattice disposed on the substrate. The bone interfacing lattice includes at least two layers of elongate curved structural members.

Also, the first layer has a first deformability and the second layer has a second deformability, wherein the second deformability is greater than the first deformability. Further, one or more of the elongate curved structural members may have a spiraling geometry.

A targeting system for aligning an axis of a targeting sleeve and a bore in a distal end portion of an intramedullary nail is proposed, the targeting device comprising a distal targeting arm with a first end being configured to be coupled to a trailing end of an intramedullary nail, an adjusting device, the adjusting device being configured to be coupled to the distal targeting arm.

A reconfigurable bone adjustment device includes a first member configured for attachment to a first bone fragment, portion, etc., a second member configured for attachment to a second bone fragment, portion, etc., a drive mechanism configured to move the second member relative to the first member, a threaded rod having a proximal end operatively coupled to the drive mechanism and a distal end operatively coupled to the second member so that rotation of the drive mechanism rotates the threaded rod and moves the second member relative to the first member, and a dynamic segment positioned between the first and second members to enable compression of the second member relative to the first member to stimulate bone growth. The dynamic segment may be a silicone/rubber compressible member or assembly, a metallic spring, a non-metallic shock absorbing material or washer, or the like.

A system for targeting a feature on a surgical device, includes a shape sensing element coupled to an interrogator and operable to provide information to related to said portion's position in a reference frame in communication with the targeted feature. The interrogator is operable to poll the shape sensing element for information related to said portion's position in the reference frame. A surgical tool is coupled to the targeting system in communication with the shape sensing element. The data processor is operable to communicate with the interrogator to output position information of the portion of the shape sensing element with respect to a calibrated position, defined as the position of the portion of the shape sensing element in the reference frame when the guide axis is aligned to the targeted feature. A display provides the user visual information comparing the position of the tool to the targeted feature.
