Each of the core, the shell and the intermediate shell is made of a different material or a different combination of materials. Both the core and the intermediate shell are sacrificial. Additive manufacturing of the tubular structure is usable for fabricating an object featuring properties of a blood vessel.Type: ApplicationFiled: July 27, 2018Publication date: November 26, 2020Applicant: Stratasys Ltd.Inventors: Daniel DIKOVSKY, Amit FEFFER

Publication number: 20200368010Abstract: Some embodiments are directed to methods and systems for percutaneously treating dissections in a patient's vasculature, such as, without limitation, the aorta. The method can include deploying a catheter containing a collapsed anchoring element, frame, and cover through a first vessel to an entry point of the dissection. The anchoring element can be secured to the second branch vessel. The frame can be expanded in the first branch vessel. The cover can be unfolded over at least a portion of the entry point. The cover then reduces blood flow into the entry point.Type: ApplicationFiled: August 12, 2020Publication date: November 26, 2020Inventor: Stefan G. Schreck

Publication number: 20200368011Abstract: There is described an arteriovenous fistula stent, having a tubular body comprising a series of sinusoidal shaped struts along the length of the tubular body. A plurality of curvilinear connectors extend between and are attached to adjacent struts wherein a first end of a connector is attached to a distal face of a proximal strut apex and a second end of a connector is attached to a proximal face of a distal strut apex. A pair of unconnected strut apexes are between pairs of connected apexes. When the tubular body is in a stowed configuration a proximal aperture and a distal aperture are circular and when the tubular body is in a deployed configuration the distal aperture is oblong or ovoid. There is also described a method for inserting a stent for use in creation of an arteriovenous fistula by identifying a candidate artery and a candidate vein and dissecting the candidate vein. Next, inserting a stent into the vein and creating a breach in the candidate artery at a desired angle and location.Type: ApplicationFiled: August 13, 2020Publication date: November 26, 2020Inventor: Marius C.

Publication number: 20200368014Abstract: A prosthetic heart valve can include a valve frame having a wireform portion and a stent portion. The wireform and stent portions can be undetachably coupled together via a plurality of upright struts so as to form a one-piece prosthetic heart valve frame. Alternatively, a self-expanding wireform portion and a balloon-expandable stent portion can be coupled together via one or more leaflets and a subassembly having a flexible leaflet support stent and a sealing ring. The wireform portion can include cusps and commissures configured to support a plurality of leaflets. The prosthetic valve can be radially collapsible for minimally invasive and/or transcatheter delivery techniques. Disclosed embodiments can also provide flexion of the wireform portion (e.g., of the commissures) in response to physiologic pulsatile loading when the valve is implanted in a patient's native valve annulus. Methods of making and using prosthetic heart valves are also disclosed.Type: ApplicationFiled: August 10, 2020Publication date: November 26, 2020Inventor: Brian S. Conklin

Publication number: 20200368015Abstract: Methods are described herein for delivering a replacement valve to a native valve location. In one method, ventricular anchors of the replacement valve are released and allowed to reverse orientation while positioned in the atrium of a human heart. After reversing orientation, the ventricular anchors extend in a generally proximal direction. The ventricular anchors can then be advanced through the annulus into the ventricle and then moved back toward the atrium to capture native valve leaflets between the main body and the ventricular anchors of the replacement valve. In one modification, the ventricular anchors are allowed to reverse orientation at a level adjacent the annulus. The implantation methods described herein are preferably performed via a transseptal delivery approach or a transapical delivery approach.Type: ApplicationFiled: August 14, 2020Publication date: November 26, 2020Inventors: J.

Publication number: 20200368016Abstract: Devices for assisting with the functioning of a tricuspid valve of a heart include a shaft, a flow optimizer, and an anchoring mechanism. A tilting mechanism can be configured to tilt the shaft relative to a central axis of the anchoring mechanism. Leaflets (e.g., multi-layer leaflets) of the flow optimizer can include a membrane and a rim, and the rim can have a higher stiffness than the membrane.Type: ApplicationFiled: May 22, 2020Publication date: November 26, 2020Inventors: Luca PESCE, John Paul USSIA, Christine Thanh NGUYEN, Christine Thao NGUYEN

Publication number: 20200368018Abstract: Prosthetic heart valves are described. Prosthetic heart valves can include radially expandable and compressible inner and outer metal frames. The inner frame can be disposed within a lumen of the outer frame and can be coupled to the outer frame. An outflow end of the inner frame can be coupled to and/or located at an outflow end of the outer frame. An end portion of the inner frame can be spaced radially inwardly from an inner surface of the outer frame, such that a radial gap exists between the inner surface of the outer frame and an outer surface of the inner frame. Prosthetic heart valves can further include a plurality of leaflets disposed within and supported by the inner frame, such as by commissure posts of the inner frame.Type: ApplicationFiled: August 13, 2020Publication date: November 26, 2020Applicant: Edwards Lifesciences CorporationInventors: Netanel Benichou, Stanton J.
