摘要： An embolic protection device includes an expandable and contractible filter that can be supported by one or more struts. The struts can be connected to the filter or interwoven into the filter, so as to assist in the expansion and contraction of the filter. In one embodiment, the proximal ends of the struts connect to a joint that is fixed in position relative to a delivery wire, while the distal end of the filter connect to a joint that slides relative to the delivery wire.

摘要： An infusion system includes an infusion catheter defining a fluid passage extending between a proximal catheter end and a distal catheter end, and having a plurality of infusion ports in communication with the fluid passage and defining an infusion zone. A filtration device is provided which may be retrofitted upon the infusion catheter and includes a filter sleeve coupled to a slidable control sleeve. The filter sleeve is deformable between a first configuration having a radially contracted footprint and a second configuration having a radially expanded footprint, responsive to sliding the control sleeve over the infusion catheter such that the deformable filter sleeve buckles outwardly from the infusion catheter.

摘要： An endovascular valve device for use in a vessel during a therapy procedure includes a catheter having at its distal end a valve. The valve is constructed of a braid of elongate first filaments coupled together at their proximal ends in a manner that the first filaments are movable relative to each other along their lengths. The first filaments have a spring bias that radially expands the valve. A filter is provided to the braid formed by electrostatically depositing or spinning polymeric second filaments onto the braided first filaments. The lumen of the catheter is in communication with the center of the valve. The device is used to provide a therapy in which a therapeutic agent is infused into an organ.

摘要： A method of preventing ingress of material into the left atrium of a heart includes providing a delivery sheath, advancing the sheath distal end through an opening between the right atrium and the left atrium of the heart, providing an expandable cage, delivering the expandable cage to the left atrium, and expanding the expandable cage within the left atrium. The expandable cage includes a proximal end, a distal end, and a plurality of supports extending therebetween. The expandable cage also includes a first membrane provided at its proximal end and a second membrane provided at its distal end. The expandable cage has a collapsed configuration so that it can be received within the lumen of the delivery sheath, and an expanded configuration for deployment within the heart. When expanded, the first membrane is positioned at an opening between the left and right atria of the heart, and the second membrane is positioned at the ostium of the left atrial appendage. The first membrane substantially prevents passage of blood between the atria and the second membrane prevents passage of embolic material from the left atrial appendage into the left atrium of the heart.

摘要： An apparatus for crimping a radially expandable stent includes a pressure vessel, shaping balloon, and mandrel. The mandrel is configured to slidingly receive a stent thereon, and to be slidingly advanced into the pressure vessel. The shaping balloon is inflated to radially compress the stent onto the form of the mandrel; such compression need not be uniform. Pressurization of the shaping balloon facilitates the expansion of the balloon to achieve compression of the stent, with depressurization of the shaping balloon causing the balloon to return to an unexpanded state.

摘要： Described herein are flexible implantable devices or stents that can conform to the shape of vessels of the neurovasculature. In some embodiments, the devices can direct blood flow within a vessel away from an aneurysm or limit blood flow to the aneurysm. In some embodiments, a vascular remodeling device includes a first section and a protruding section. During deployment, the device expands from a compressed configuration to an expanded configuration. The first section anchors the device in an afferent vessel and/or in an efferent vessel of a bifurcation and the protruding section is positioned in the junction of the bifurcation having an aneurysm and across the neck of the aneurysm or at least partially within the aneurysm.
