20090018636 | Methods and apparatus for rapid endovascular vessel occlusion and blood flow interruption - An occluding device including expandable scaffold and a flow-limiting member is described. In some embodiments the scaffold is an expandable or self-expanding stent deliverable over a guide wire. The flow-limiting member can include a valve that can be closed following deployment. On deployment the stent and flow-limiting member can engage an inner surface of a body cavity lumen, blocking flow of material. In some embodiments the body cavity is a blood vessel, and the device can be used to block blood flow. In some embodiments the device includes bioactive agents. | 01-15-2009 |

20100063582 | ENDOVASCULAR DEVICE - Embodiments of an endovascular device and of methods for treating an aneurysm therewith are described. In certain embodiments, an endovascular device includes a distal assembly coupled to a flow reducing member. In some embodiments, the distal assembly is composed of multiple engagement members that, when deployed within an aneurysm, engage an inner surface of the aneurysm. In certain embodiments, the engagements members are substantially parallel to a central axis of the distal assembly in a first position and shift away from the central axis to a second position, and the distal ends of some engagement members are substantially curled when in the second position. In certain embodiments, the flow-reducing member reduces blood flow from a blood vessel into the aneurysm. In certain embodiments the flow reducing member includes a membrane, which can include a porous section. | 03-11-2010 |
20110319906 | REDUCING FLOW THROUGH A TUBULAR STRUCTURE - In some embodiments, an apparatus, for reducing or stopping flow through a tubular structure of a patient, includes an elongate member arranged to form a frame having a distal and proximal opening and configured to be positioned within a lumen of the tubular structure. The frame includes a proximal, distal, and middle portion. The distal portion is tapered such that an outer cross sectional dimension (OCSD) of the distal opening is less than an OCSD of the middle portion. The frame is configured to be inverted such that the distal portion moves within and toward the middle portion for removing the frame from within the lumen. The apparatus also comprises a flow reducing member coupled to the frame such that when the frame is positioned within the lumen, the flow reducing member substantially reduces or totally obstructs flow of at least one of emboli and fluid flowing through the lumen. | 12-29-2011 |
20120095489 | EXPANDABLE DEVICE DELIVERY - A device for delivering an expandable member to a luminal structure in a patient is described. In some embodiments, the device has a carrier member, with a carrier lumen extending at least partially therethrough. The device can have an elongate member that extends through the carrier lumen across a first notch in the carrier member. The device can have an expandable member that expands within and engages the luminal structure, can be carried by the carrier member, and has a first portion that fits within the first notch. When the elongate member extends through the carrier lumen and across the first notch, the elongate member secures the first portion to the carrier member. The elongate member is configured to move axially through the carrier lumen such that the elongate member permits release of the first portion from the carrier member and expansion of at least part of the expandable member. | 04-19-2012 |
20130053879 | METHODS AND APPARATUS FOR RAPID ENDOVASCULAR VESSEL OCCLUSION AND BLOOD FLOW INTERRUPTION - An occluding device including expandable scaffold and a flow-limiting member is described. In some embodiments the scaffold is an expandable or self-expanding stent deliverable over a guide wire. The flow-limiting member can include a valve that can be closed following deployment. On deployment the stent and flow-limiting member can engage an inner surface of a body cavity lumen, blocking flow of material. In some embodiments the body cavity is a blood vessel, and the device can be used to block blood flow. In some embodiments the device includes bioactive agents. | 02-28-2013 |

20140215792 | BODILY LUMEN OCCLUSION - An occlusion system can include an expandable implant that can be delivered to a bodily lumen. The implant can be carried on an engagement section of a catheter used in the system. The implant can be assembled onto the catheter by coupling a cover member of the implant with a support member of the implant. When assembled, the system can be advantageously configured to have a low delivery profile to facilitate delivery through catheters having a size of less than 7 Fr, and in some cases, less than 6 Fr. | 08-07-2014 |
20140222059 | METHODS AND APPARATUSES FOR BLOOD VESSEL OCCLUSION - An occlusion device delivery system and methods are provided in which an expandable coiled implant can be delivered using the delivery system. The system can comprise a catheter having a lumen extending between distal and proximal portions. The distal portion can have proximal and distal apertures extending through a wall of the catheter. The expandable coiled implant, which can be wound about the distal portion, can have a proximal section that extends within the proximal aperture and a distal section that can extend radially within the distal aperture. Further, the system can comprise an elongate member that extends through the lumen and engages and radially restrains the at least one of the proximal and distal sections within its respective aperture while engaged with the member. | 08-07-2014 |
20140257369 | BLOOD VESSEL OCCLUSION - An occlusion device delivery system can deliver an expandable coiled implant using a catheter. A distal portion of the catheter has proximal and distal apertures extending through a wall of the catheter. The expandable coiled implant is wound about the distal portion and has a proximal section that extends within the proximal aperture and a distal section that can extend radially within the distal aperture. Further, the system has an elongate member that extends through the lumen and engages and radially restrains the at least one of the proximal and distal sections within its respective aperture while engaged with the member. | 09-11-2014 |
20140371716 | CATHETER-BASED CANCER THERAPY - An implant can include a support component, a cover component, and a valve component. The valve component can be operable to permit flow through the implant. The implant can be delivered on a catheter, with one of the ends of the implant being selectively expanded to permit temporary occlusion of a vessel while delivering a material through the valve component to a downstream target region. The other end of the implant can thereafter be released such that the implant occludes the vessel, or the implant can be removed from the vessel entirely. | 12-18-2014 |
20140371777 | IMPLANTABLE LUMINAL DEVICES - An implant may include a frame and a cover to facilitate endoluminal vessel occlusion, selective release of embolic material toward a target region, and/or endoluminal stenting. The frame of the implant provides radial expansion properties to secure the cover within a body vessel. The cover and/or the frame can occlude flow of a fluid through the body vessel. | 12-18-2014 |
20140371778 | IMPLANTABLE LUMINAL DEVICES - An implant may include a frame and a cover to facilitate endoluminal vessel occlusion, selective release of embolic material toward a target region, and/or endoluminal stenting. The frame of the implant provides radial expansion properties to secure the cover within a body vessel. The cover and/or the frame can occlude flow of a fluid through the body vessel. | 12-18-2014 |
