Inflatable medical devices
Inflatable medical devices and methods for making and using the same are disclosed. The inflatable medical devices can be medical balloons. The balloons can be configured to have a through-lumen or no through-lumen and a wide variety of geometries. The device can have a high-strength, non-compliant, fiber-reinforced, multi-layered wall. The inflatable medical device can be used for angioplasty, kyphoplasty, percutaneous aortic valve replacement, or other procedures described herein.
Apparatus and method for percutaneously extending an existing spinal construct
Apparatus and devices for percutaneously extending an existing spinal construct ipsilaterally with an additional spinal construct in a patient are disclosed. The additional spinal construct comprises a rod connector that includes an elongate additional rod integrally attached thereto. The additional rod is placed through an access port in a first orientation generally parallel to the longitudinal axis of the access port and rotated to a different second orientation generally transverse to the longitudinal axis of the access port. During such rotation the additional rod is moved subcutaneously beneath the skin of the patient from the existing spinal rod to an additional bone engaging implant. In another arrangement, the extension of an existing spinal construct in a minimally invasive procedure comprises a rod connector having an offset support for receiving an additional spinal rod that may be placed laterally interiorly or exteriorly of the existing spinal construct.

Instrument for inserting a spinal device
In one aspect, a bone anchor assembly is provided having a bone anchor with a head, a resilient locking cap extending about a portion of the bone anchor head, and a cap drive member having a depending annular wall. In another form, a bone plate system is provided including a bone plate having an elongated throughbore and a resilient support member received therein. In another aspect, an insertion device is provided for manipulating and inserting a spinal device at or within a spinal joint. The insertion device is configured to actively pivot the implant about the implant gripping end of the device and to allow manipulation and release of the implant in any pivoted orientation from approximately 0 to 90 degrees.
Shaper for vertebral fixation rods
A system for rod bending for use in robotic spinal surgery, enabling the correct bending of a fusion rod to match the shape required to accurately pass through the heads of the pedicle screws. The system uses data generated by information provided to the robot by the surgeon's preoperative plan, optionally augmented by feedback from the robot control system of deviations encountered intraoperatively. Such deviations could occur, for example, when the surgeon decides intraoperatively on a different trajectory or even to skip screws on one vertebra, in which case, the robot will be commanded to perform the alternative procedure, with commensurate instructions relayed to the control system of the rod-bending machine. The system is also able to thin down the rod at predetermined locations along its length, adapted to be at selected intervertebral locations, for maintaining limited flexibility between vertebrae, instead of fixating them.
BONE FRACTURE FIXATION DEVICE AND RELATED SYSTEMS AND METHODS
The various embodiments disclosed herein relate to bone fixation devices, including intramedullary fixation or fusion devices. The various devices disclosed include an intermedullary rod or device having a proximal and a distal portion. The proximal and distal portions having articulated ends that are coupled to form a joint. The joint may be actuated to reduce a fracture and realign the bone after insertion of the device into the bone.
POSTERIOR STABILIZATION SYSTEMS AND METHODS
An implantable body for a posterior stabilization system includes a lateral end, a medial end, an inwardly facing surface configured to abut against a lamina when the body is implanted along a vertebra. A lateral bone outrigger extends from the inwardly facing surface and may include a bone-abutting surface along a medial portion disposed to abut against a lateral mass of the vertebra when the body is implanted along a vertebra. The lateral bone outrigger may have a first height. A penetrating feature extends from the inwardly facing surface between the bone-engaging portion of the inwardly facing surface and the lateral bone outrigger. The penetrating feature may have a second height less than the first height. A fastener bore extends through the body at an angle toward the lateral bone outrigger.
Intra-articular joint replacement
A method of forming a shoulder prosthesis includes resecting an end portion of a humerus to form a resected end of the humerus and a resected portion separated from the humerus, the resected portion having an outer convex surface and an inner surface. The inner surface of the resected portion is processed to include a concave articular surface. The outer convex surface of the resected portion is implanted in the resected end of the humerus. An implant having a convex articular surface is secured to a glenoid. The concave articular surface of the resected portion is articulated with the convex articular surface of the implant.
Locking element for a polyaxial bone anchor, bone plate assembly and tool
A locking element is configured to be used with a polyaxial bone anchor. The locking element including a central axis, a bottom side, a top side opposite to the bottom side, and a peripheral surface portion that extending completely around the locking element that has an external thread. The bottom side defines a first recess facing toward the bottom side for accommodating and applying a force in a direction toward the bottom side to at least the portion of the head of the polyaxial bone anchor. The top side defines a second recess having a non-circular cross-section in a plane perpendicular to the central axis for torqueable engagement with a driver.
Method and apparatus for minimally invasive insertion of intervertebral implants
A dilation introducer for orthopedic surgery is provided for minimally invasive access for insertion of an intervertebral implant. The dilation introducer may be used to provide an access position through Kambin's triangle from a posterolateral approach. A first dilator tube with a first longitudinal axis is provided. A second dilator tube may be introduced over the first, advanced along a second longitudinal axis parallel to but offset from the first. A third dilator tube may be introduced over the second, advanced along a third longitudinal axis parallel to but offset from both the first and the second. An access cannula may be introduced over the third dilator tube. With the first, second, and third dilator tubes removed, surgical instruments may pass through the access cannula to operate on an intervertebral disc and/or insert an intervertebral implant.
