摘要： Intrasaccular flow diverter including: an interior fill braid physically inverted over itself forming a proximal inverted end and an opposite free end; and a dome braid disposed distally of and secured to the interior fill braid. Subject to application of an external mechanical force, the dome braid is transitionable between an expanded state and a compressed state. The dome braid has a proximal end with an opening defined therein through which starting at the free end the interior fill braid is passable therethrough exerting a radially outward force on the dome braid. A delivery wire is releasably detachable from the proximal inverted end of the interior fill braid. The dome braid has a stiffer profile relative to that of the interior fill braid to maintain in position within the aneurysm the dome braid as the interior fill braid is advanced therein.

摘要： A delivery system for delivering and deploying an implantable medical device is presented that includes a delivery member having a flexible distal portion. The deliver member can include a proximal hypotube, a flexible coil extending distally from the proximal hypotube, a compressible distal hypotube extending distally from the flexible coil, a sleeve extending along the flexible coil, and a loop wire. The loop wire can be effective to inhibit longitudinal elongation of the flexible coil. The sleeve can be effective to inhibit radial expansion of the flexible coil.

摘要： An occlusion device that includes an inner embolic element with a proximal section and a distal section, wherein the distal section has a first stiffness and the proximal section has a second stiffness. An expandable mesh is included that is capable of being transformed between a collapsed position and an expanded position, wherein the expandable mesh is disposed over a portion of the proximal section of the inner embolic device and the first stiffness is greater than the second stiffness.

摘要： An aneurysm implant support device for treating an aneurysm at a bifurcation can include a body having a tubular lattice extending from an upper body section, through a mid body section, and to a lower body section. The upper body section can be sized, shaped, and otherwise configured for implantation in an aneurysm sac. The upper body section can include support elements positioned at the aneurysm neck which inhibit the embolic implants from exiting the aneurysm. The mid body section can have two large cell openings substantially larger than the cell openings over a majority of the tubular lattice. The two large cell openings can be placed across passageways from a stem blood vessel to branch blood vessels of the bifurcation. The lower body section can be sized, shaped, and otherwise configured to anchor within the stem blood vessel.

摘要： A tubular braided implant is provided including a braid that can be delivered as a single layer braid, invert into itself during deployment to form at least two nested sacks and include additional braid material that can fill the innermost sack. The additional braid material can loop or coil like a ribbon and/or invert to form smaller and smaller nested sacks. The braid can have a variable braid angle along its length such that when positioned for delivery, the can have a high braid angle near its distal end and a low braid angle near the proximal end. In addition, or as a replacement for the braid material that fills the innermost sack, the implant can include an embolic coil that can loop within the innermost sack.

摘要： A method of delivering a catheter to a location of interest in the vasculature, the method including positioning a self-expanding sheath within a lumen of the catheter; advancing the catheter and the self-expanding sheath in tandem over a guidewire; and distally moving a distal end of the self-expanding sheath out from the lumen of the catheter thereby causing the self-expanding sheath to move from a collapsed state within the catheter to an expanded state outside the catheter, wherein when the self-expanding sheath is in the expanded state both the self-expanding sheath and the catheter are distally advanceable in tandem.

摘要： An implant having an embolic portion and a braided tubular occluding portion can be delivered through a catheter and implanted in an aneurysm. The embolic portion can be an elongated embolic structure that can coil as it is inserted into an aneurysm sac. The occluding portion can be a braided tube that is shaped to encircle the elongated embolic portion during delivery and expands to form a cup shape within the aneurysm sac, nesting in the aneurysm neck when implanted. The implant can include a closure mechanism positioned between the occluding portion and the embolic portion that can serve the purpose of restricting an end of the occluding portion at the trough of the cup shape, connecting the embolic portion to the occluding portion, and/or providing a detachment feature for connecting to a delivery system.

摘要： Systems and methods for delivering a catheter to a location of interest in the vasculature, the method including selectively positioning a guidewire at the location, positioning a self-expanding sheath within a lumen of the catheter, advancing the catheter and the self-expanding sheath in tandem over the guidewire, and distally moving a distal end of the self-expanding sheath out from an inner lumen of the catheter thereby causing the self-expanding sheath to move from a collapsed state within the catheter to an expanded state outside the catheter.

摘要： An embolic coil implant having a stretch resistant fiber therethrough and dual-functional engagement feature at its proximal end is provided. The stretch resistant fiber can be effective to limiting separation of windings of the embolic coil. The engagement feature can provide an attachment for securing the embolic coil to an engagement system of a delivery tube and for securing the stretch resistant fiber at the proximal end of the embolic coil.
