A method of making a delivery system for a prosthesis includes providing a catheter shaft, sliding a plurality of rings over the catheter shaft, each of the rings having an inner diameter larger than an outer diameter of the catheter shaft, fixing a pull wire to each of the plurality of rings at a common circumferential location of the catheter shaft, and coupling a sheath to the pull wire, the sheath positioned over the prosthesis at a distal end of the catheter shaft. Fixing the pull wire to each of the plurality of rings can include wrapping a heat shrink film around each of the plurality of rings and the pull wire, and heating the heat shrink material.

A stent delivery system for treating a bifurcated vessel includes a first elongate shaft with a first expandable member. A first stent having a side hole is disposed over the first expandable member. A second elongate shaft has a second expandable member. The second elongate shaft is slidably disposed under the proximal end of the first stent and extends out of the side hole. The first stent is fully crimped over a proximal portion and a distal portion of the first expandable member and a proximal portion of the second expandable member so as to prevent axial movement of the first stent relative to the first or second elongate shafts during delivery. Portions of the first or second expandable members may be pillowed to provide a protective barrier that prevents edges of the stent from catching on other objects.

Embodiments of the present invention provide a unique new approach to generating operating condition information used for assessing flow assurance and structural integrity. More specifically, apparatuses, systems and sensor housing assemblies configured in accordance with embodiments of the present invention utilize fiber optic sensors for enabling monitoring of operating condition information within one or more elongated tubular members within a subsea environment. To this end, such fiber optic sensors connected by lengths of optical fiber are strategically placed at a plurality of locations along a length of each elongated tubular member thereby allowing critical operating conditions such as strain, temperature and pressure of the elongated tubular member and/or a fluid therein to be monitored. A viscous media is used for mitigating attenuation associated with exposure of optical fiber exposed to forces generated by pressure within the subsea environment.

Methods and devices useful, for example, in the field of angioplasty and stenting are disclosed. In some embodiments, the methods, devices and kits are configured for directional expansion inside a lumen, for example of a blood vessel obstructed by plaque. In some embodiments, the directional expansion displaces the plaque in a desired direction.

The present disclosure relates to an endoluminal prosthesis, such as a stent graft that includes one or more fenestrations to accommodate endovascular disease, such as an aneurysm in cases where one or more side branches is involved. In one aspect, the prosthesis includes fenestrations that are pivotable to accommodate the dynamic geometry of the aortic branches.
