Patent number: 10925635Abstract: Provided is a method performing vascular surgery utilizing a guiding apparatus that includes an adaptor and an introducer, by inserting a longitudinal section of the adaptor into the introducer and operating a valve of the introducer by moving a cursor provided on a side wall of the introducer within a travel region of the cursor. Operating the valve either fixedly attaches or releases the longitudinal section of the adaptor within or from the introducer. The adaptor includes an inner volume that encloses a plurality of ducts and the introducer includes an inner volume that aligns with the inner volume of the adaptor when the valve is fixedly attached the longitudinal section of the adaptor within the introducer, thereby providing ducts that allow an instrument to pass entirely through both the adaptor and the introducer.Type: GrantFiled: February 22, 2018Date of Patent: February 23, 2021Inventor: Claude Mialhe

Patent number: 10314687Abstract: A stent-graft suitable for chimney grafting comprising a sheath and a tubular framework defining a lumen. The stent-graft comprises, at one end of the sheath, at least one bucket formed at the end so as to form a depression in the sheath able to mate with a collateral stent. The stent-graft is applicable to the treatment of vascular pathologies, in particular to treat aneurysms. More particularly, the stent-graft is an endoprosthesis designed to be placed in parallel with at least one other endoprosthesis.Type: GrantFiled: November 4, 2014Date of Patent: June 11, 2019Inventor: Claude Mialhe

Publication number: 20160310304Abstract: Provided is an implant placement device that includes an envelope that contains an implant with a first auto-expandable element expandable in a radial direction, a nose at a distal end of the envelope, a sheath that confines a portion of the implant therein and restricts expansion of a second auto-expandable element of the implant, and a plunger. The sheath moves within the envelope in a longitudinal direction perpendicular to the radial direction and the plunger moves in the longitudinal direction within the sheath with the implant positioned between an end of the plunger and the nose, to discharge the implant from the device at a desired position. The sheath slides in the longitudinal direction towards the nose to bring the first auto-expandable element in contact with an interior of the plurality of slots, thereby opening the nose.Type: ApplicationFiled: July 5, 2016Publication date: October 27, 2016Inventor: Claude MIALHE

Patent number: 9398916Abstract: A device for placing a vascular implant including a device for dilating a vessel, has an outer envelope and a tapered end piece for introduction into a vessel. The end piece includes a nose formed at the distal extremity of the outer envelope. The dilation device includes elements for opening the nose having at least two longitudinal slots which divide the nose into several segments which can be opened out in order to open the nose; and an implant which is placed in the outer envelope. The implant includes an expandable element which can be placed in the outer envelope. The implant includes an expandable element which can be placed on the internal wall of the outer envelope and is provided with elements for the translation of the implant in relation to the outer envelope such that the expandable element can press against the internal wall of the nose in order to open out the segments. A device for placing vascular implants fitted with the device is also disclosed.Type: GrantFiled: March 22, 2004Date of Patent: July 26, 2016Inventor: Claude Mialhe

Patent number: 8709067Abstract: The present invention provides, in a first aspect a bifurcated stent for use in juxtaposition with an angelogical bifurcation. The bifurcated stent comprises a proximal portion adapted to be disposed within a blood vessel in juxtaposition with a bifurcation, a first distal stent portion adapted to extend across the bifurcation into one of the branched blood vessels, and a second distal stent portion adapted to allow blood to flow from the proximal portion into the other branch blood vessel. The invention also embraces a bifurcated prosthesis including such a bifurcated stent and a tubular graft layer formed from a biocompatible fabric in juxtaposition with the stent. In a second aspect of the invention there is provided a stent connection for joining two stents one to the other to define a continuous lumen through the two stents. Said stent connection comprises a first stent including a male engaging portion which can be compressed radially inwardly and a second stent including a female cooperating portion.Type: GrantFiled: August 31, 2012Date of Patent: April 29, 2014Assignee: Lifeshield Sciences, LLCInventors: Andrew H.
