The disclosure relates to cannulae, delivery systems, methods of making cannulae, and methods of making delivery systems. A delivery system comprises an elongate outer tubular member defining an outer tubular member lumen, a cannula having a circumferential wall extending between a proximal end and a distal end and defining an interior lumen, and an intraluminal medical device disposed within the outer tubular member lumen distal to the cannula and not about the cannula. A pattern of openings arranged in an interrupted spiral extends circumferentially along the cannula.

Medical cannulae, delivery systems and methods

Disclosed herein is a stent which is compressible to small diameter and usable in neurovascular applications. The device is a braided stent and has a crown geometry which enables compression to small diameter without cracking or tangling. Also disclosed is a method of deploying a stent to a body vessel and its use in a coiling procedure.

Braided stent crown geometry and flare

The disclosure relates to cannulae, delivery systems, methods of making cannulae, and methods of making delivery systems. A cannula comprises an elongate tubular member having a circumferential wall extending between a proximal end and a distal end and defining an interior lumen. A pattern of openings arranged in an interrupted spiral extends circumferentially along the elongate tubular member.

Variable stiffness cannulae and associated delivery systems and methods

The disclosure relates to medical devices comprising coaxial cannulae. A medical device includes an outer cannula and a coaxial inner cannula that is secure to the inner cannula. The circumferential wall of one of the cannulae defines a pattern of openings that extends along a spiral path about the lengthwise axis of the cannula.

Medical devices having coaxial cannulae

A cannula cut spiral flow inducing stent includes a plurality of spiral inducing flow diverters that each include a piece of sheet metal with a helically shaped flow surface. A proximal stent region, which includes a plurality of first struts, is joined to a proximal end of each of the spiral inducing flow diverters. A distal stent region, which includes a plurality of second struts, is joined to a distal end of each of the spiral inducing flow diverters. All of the first struts and all of the second struts share a cannula thickness, but the shaped pieces of sheet metal may have a lesser thickness.

Spiral flow inducing stent and canula cut method of making same

A spiral blood flow device includes a stent made up of a plurality of expansion members joined to a plurality of axial members that permit the stent to change diameter among a continuum of expanded configurations. The axial members have fixed orientation, whereas the expansion members have a variable orientation relative to the longitudinal axis throughout the continuum of expanded configurations. A spiral flow inducing structure, which may include fins attached to the axial members, define a helical flow angle that remains constant throughout the continuum of expanded configurations.
