20080262595 | Methods and Apparatus for Treatment of Aneurysms Adjacent to Branch Arteries - A stent graft includes at least one aperture extending through the main body thereof, into which an extension portion may be deployed for positioning within an adjacent branch flow lumen. The extension portions include self biasing features, wherein the extension is biased into engagement with the main body to seal the interface thereof. Additionally, the extension portion may be configured for tortuous or deviated anatomy, to enable sealing of the extension portion with the body while extending the extension portion in a substantially non-radial direction from the main body. | 10-23-2008 |
20090012597 | Universal Modular Stent Graft Assembly to Accommodate Flow to Collateral Branches - Universal modular stented graft assemblies are assembled, on site, and often in a patient's parent artery, from at least two components; a first component and a second component. The first and second components each include a window, or fenestration. The second component couples with the first component by fitting at least partially in the first component to form the universal modular stent graft assembly with an adjustable collateral opening. As the first and second components are assembled, the first and second components are adjusted relative to each other so that the first and second component windows overlap to form a collateral opening whose size is selectable, depending on the overlap, with the desired position and dimensions in the universal modular stent graft assembly. | 01-08-2009 |
20090270966 | Stent Graft System and Method of Use - A stent graft system and method of use includes a stent graft for fixation at an attachment site with graft material defining at least one opening having an opening perimeter; a support attached to the graft material; a guide rail attached around the opening perimeter; and a helical anchor having a plurality of coils with a point at one end. The plurality of coils are rotatable around the guide rail to cause the pointed end of the coils to penetrate the graft material and the adjacent tissue in contact with the stent graft to sew the stent graft to the attachment site. | 10-29-2009 |
20100121429 | Stent Graft Having a Flexible, Articulable, and Axially Compressible Branch Graft - A stent graft and method for positioning and deploying the stent graft within a vessel system that includes a main vessel and a branch vessel emanating from the main vessel. The stent graft includes a tubular shaped main body formed from graft material, a branch opening (aperture) (ring) in the graft material of the main body whose position can be varied. A tubular shaped branch graft can extend from the main graft. A side wall of the main body may be configured as a series of connected annular corrugations or pleats, and coupled to the main body to define and provide variable positioning of its branch opening (aperture). | 05-13-2010 |
20100125282 | Robotically Steered RF Catheter - A distal end of a stent graft fenestration or other special purpose catheter is guided to a location in a patient's vasculature based on input from a surgeon using a pre-operatively generated image of the patient's vasculature—this can be in proximity to an already implanted device. The movement of the catheter is controlled by a robotic surgical system based upon the input from the surgeon. The distal end of the catheter, at the location, is synchronized to the patient's cardiac cycle so the robotic surgical system maintains the distal end of the catheter at the location throughout a cardiac cycle of the patient. The surgeon is not required to precisely manipulate the catheter to maintain the distal end in the proper location throughout the cardiac cycle. The surgeon can focus on performing the desired procedure such as fenestrating the stent graft, endostapling or endosuturing, for example. | 05-20-2010 |
20100179632 | Robotic Fenestration Device Having Impedance Measurement - A method and system for real-time continuous impedance monitoring along the surface of a graft implanted within a main vessel to aid in optimally positioning an electrode at a branch vessel ostium. Due to the conductivity differences among various kinds of solid tissue and blood, a fenestration catheter system uses impedance monitoring as a tool to detect the location of branch ostia through graft cloth. Such information enables the fenestration electrode to be properly positioned for creation of a fenestration in the graft cloth in situ. In addition, the fenestration catheter system may utilize impedance information to avoid contact between the electrode and metal stent structures used to anchor the graft during an in situ fenestration procedure. The fenestration catheter system includes a catheter shaft, an electrode, one or more reference or indifferent electrodes, an impedance analyzer, a power source and an electrode position reference to record impedance measurements in relation to position. | 07-15-2010 |
20100241163 | Aortic Dissection Treatment System and Method of Use - An aortic dissection treatment system and method of use including a treatment system for an aortic dissection having a catheter defining a suction lumen and a sealant lumen; a flexible cup defining an isolation region within the flexible cup, the isolation region being in communication with the suction lumen and the sealant lumen; and a sealant fluid deliverable to the aortic dissection through the sealant lumen and the isolation region. The flexible cup is sized to fit over at least one end of the aortic dissection and the suction lumen applies suction to maintain the flexible cup over the at least one end of the aortic dissection. | 09-23-2010 |
