A dual opposing helical stent having a furled, small-diameter state and an expanded, large-diameter state. In the furled, small-diameter state, the stent includes a plurality of central lobes arranged at spaced-apart intervals and extending longitudinally defining a stent axis. The stent also includes peripheral lobes formed on the plurality of central lobes. The terminal ends of the stent are welded in a middle section of the stent. A method and technique for manufacturing the stent is also disclosed.

A new approach is presented to reduce encrustation of catheters by the application of nanoparticles. It is demonstrated that the negatively surface charged nanoparticles produce coating films comprised of long-range domains in which the nanoparticles are self-assembled into a mosaic-like order, showing a relatively small tendency to agglomerate.

An embodiment includes a process for treating an abdominal aortic aneurysm (AAA) endoleak with a shape memory polymer (SMP) foam device. First, a bifurcated stent graft is placed within the aneurysm while a micro guidewire is positioned within the aneurysm for future catheter access. Second, after placing the iliac graft extension, a catheter is introduced over wire to deliver embolic foams. Third, embolic foams expand and conform to the aneurysm wall. Fourth, embolic foams create a stable thrombus to prevent endoleak formation by isolating peripheral vessels from the aneurysm volume.

Absorbent medical articles include a first absorbent layer with a radio opaque element located on the surface of the first absorbent layer. The radio opaque element has at least one segment that is non-linear and has at least one vertex, the vertex defines an angle of at least 15° and less than 165°. The radio opaque element may be a continuous or discontinuous element. The absorbent medical article may include additional absorbent layers. The radio opaque element makes the absorbent medical article detectable if left inside a patient.

The invention describes method for delivering and positioning radio-isotopes. The method uses encapsulating free flowing medicament into a leak proof vehicle and positioning the vehicle into the body. Also provided is a system for delivering and positioning radio-isotopes into the body, the system comprising fluid radio-isotope encapsulated in a leak proof material and/or absorbable material.
