Abstract: A flow diverter is described and fabricated using ultra-thin porous thin-film Nitinol, and is configured for implantation to a treatment site within a vessel for significant reduction in an intra-aneurismal flow velocity and vorticity. Using small size pores in a coverage area of only 10%, a 90% reduction in flow velocity into a pseudo-aneurysm can be achieved, with an almost immediate cessation of flow into an anatomical feature such as aneurysm sac in vivo. The size of the holes can be tailored to be any shape and range in size from 1-400 ?m using photolithography and from 5-1000 nm using ebeam lithography.

Abstract: A modular stent graft system and methods of assembly are disclosed. The stent graft assembly comprises a first stent graft having an interface region at its distal end and a first locking stent secured to an internal surface of the interface region. A second stent graft having an interface region at its proximal end is configured to at least partially overlap with the interface region at the distal end of the first stent graft. The second stent graft comprises a second locking stent secured to an external surface of the interface region. The first and second locking stents are configured to be engaged such that the second locking stent is nested between the first locking stent and an internal surface of the interface region of the first stent graft thereby interlocking the first and second stent grafts to each other.

Abstract: A surgical drill guide for positioning, aligning, and of holes to be drilled in bone tissue has retaining means that holds the position and alignment of the drill guide body in a releasable manner with respect to a fastener hole in an orthopedic implant. The retaining means is a key guide that mates with a key way or key ways in or around a threaded locking hole of an orthopedic plate for alignment of a pilot hole and method of using the guide. The key guide has 2 to 8 projections that extend in the direction of the axis of the hole, such as hemi cylindrical projections, and the plate has a corresponding female key way that receives the retaining means. The invention also relates to a method of aligning a locking fastener in a plate at a desired angle relative to a bone by using a surgical guide having a key interface with the plate to position and align a pilot hole.
