A branched graft method includes securing a first end of a branch graft into a first conduit and subsequently moving the second end into a second conduit. The first conduit may be a branch vessel, such as a renal artery and the second conduit may be a main graft that extends over an aortic aneurysm.

AIR RELEASE QUANTIFICATION AND BACK-BLEED FLUSHING TECHNIQUES AND FEATURES FOR ENDOPROSTHESIS DELIVERY SYSTEM
Techniques and features for reduction of air potentially released during endoluminal device (e.g., thoracic aortic stent-graft device) deployment. Also addressed are methods for quantifying efficacy of pre-treatment techniques and features for reducing said air. Such air reduction can help reduce risk of air embolization during device (e.g., implant, such as stent-graft) deployment which could potentially decrease the risk of negative effects from such embolization.

Vascular filtering devices and methods for their use are disclosed. In some embodiments, the vascular filtering devices include an elongate member having an unsupported membrane bag portion attached thereto. The membrane may be porous in some examples. Multiple elongate extensions may also extend from the membrane, and may extend along the elongate member, such as to a proximal region of the elongate member. The unsupported membrane bag portion may be configured to inflate or otherwise radially expand away from the elongate member as a result of blood flowing through the vessel within which the vascular filtering device is positioned.
There is described a vent comprising a vent housing, the vent housing comprising a top portion and a base portion and at least one exterior aperture, the base portion comprising a vent aperture covered by a membrane within the vent housing, the top portion being fixed to the base portion such that a channel is formed from the at least one exterior aperture to the vent aperture through the membrane such that during use gas may flow from the vent aperture through the membrane to the at least one exterior aperture through the channel, wherein at least one opening is defined between the top portion and the base portion within the channel between the at least one exterior aperture and the vent aperture and the at least one opening has a minimum dimension of less than 0.6 mm.
Disclosed are processes and systems using asymmetric membranes for forming a plurality of particles such as liposomes, solid-lipid nanoparticles, solid nanoparticles, polymeric nanoparticles, or micelles. The membrane may have a bubble point of from 34.5 kPa to 1380 kPa, may be fibrillated and may further include a hydrophilic coating.
