A polymer coating/ring is employed to aid in the sealing and connection of modular elements used in body flow lumens for the exclusion and bypass of diseased regions of the flow lumen, such as where aneurysm occurs adjacent to branching blood vessels.

A stent graft includes at least one aperture extending through the main body thereof, into which an extension portion may be deployed for positioning within an adjacent branch flow lumen. The extension portions include self biasing features, wherein the extension is biased into engagement with the main body to seal the interface thereof. Additionally, the extension portion may be configured for tortuous or deviated anatomy, to enable sealing of the extension portion with the body while extending the extension portion in a substantially non-radial direction from the main body.

Skeletal stabilization systems include a base, a longitudinal member, and a retaining member. The base includes an engagement surface with a surface area that is positionable in contact with a bone to atraumatically or traumatically engage the base to the bone. The retaining member engages the base to retain the longitudinal member relative to the base so that the longitudinal member can provide a desired stabilization effect to one or more adjacent bony portions.

A braided flange branch graft formed of a braided super elastic memory material includes a neck between an inner flange and an outer flange. The neck is positioned in a side opening in a sidewall of a main stent graft and the inner flange and outer flange are deployed on opposite sides of the sidewall. The inner flange and the outer flange have a diameter greater than a diameter of the side opening in the sidewall of the main stent graft. Thus, the sidewall of the main stent graft is sandwiched between the inner flange and the outer flange securely and simply mounting the braided flange branch graft to the main stent graft. The braided flange has a substantially unobstructed fluid communication passage therethrough. Further, when stretched into a substantially cylindrical shape for delivery, the braided flange branch graft has a small delivery profile and is extremely flexible.

A method of securing vertebrae includes inserting a first pedicle screw into a first pedicle of a first vertebra. The first pedicle screw includes a first channel running perpendicular to a first central axis of the first pedicle screw. The first pedicle screw has a first engagement structure. The method further includes inserting a second pedicle screw into a second pedicle of a second vertebra. The second pedicle screw includes a second channel running perpendicular to a second central axis of the second pedicle screw. The second pedicle screw has a second engagement structure. The method also includes inserting a guidewire through the first and second channels, threading a tether attached to an end of the guidewire through the first and second channels, securing the tether to the first pedicle screw, applying tension to the tether, and securing the tether to the second pedicle screw.

Apparatus, systems and methods for making, using, implanting, and visualizing portions of a medical implant are provided. One such implant includes a bone plate at least partially of a radiolucent material having at least one aperture, and a fastener at least partially of a radiolucent material to extend through the aperture. The fastener has a distal end and a proximal end, with at least a portion of the proximal end is of a radiopaque material. A fastener lock is included to engage the fastener proximal end to maintain the fastener position relative to the bone plate. At least a portion of the fastener lock is of a radiopaque material. In this manner, at least a portion of the implant is adapted to be visible on a radiographic image.

Modular branch vessel stent-graft assemblies for the treatment arterial or vascular disease at the branch of two or more arteries or blood flow passageways, including, for example, abdominal aortic aneurysms are assembled in a patient's trunk/parent artery, from at least two components; a first component and a second component. The first and second components each include a first and second window, or fenestration. The second component couples with the first component by fitting at least partially in the first component to form the modular branch vessel stent-graft assembly with two selectively locatable branch openings. As the first and second components are deployed, the second component is selectively position able relative to first component so that the first and second component first and second windows overlap to form two branch openings whose longitudinal and angular positions are selectable within a range.

The present application is directed to screwdrivers and methods of use for applying a controlled amount of torque to a fastener. In one embodiment, the screwdriver includes a shaft constructed of a material that is deformable upon the application of an excessive amount of torque. The deformation may cause the screwdriver to disengage from the fastener. In one embodiment, the tip of the shaft that engages the fastener is constructed of a material that deforms when an excessive amount of torque is applied to the fastener. The deformation causes the tip to disengage from the fastener. The deformation prevents the screwdriver from applying an amount of torque above a predetermined limit.
