Abstract: A medical device for an anastomosis is provided. The medical device distinguishes an inner tubular layer, an outer tubular layer, and a support element defining a longitudinal axis. It further distinguishes two or more independent C-rings distributed and positioned at an acute orientation angle relative to the longitudinal axis of the support element at one end of the support element. The support element and the two or more C-rings are embedded in between the inner and the outer tubular layers. The types of applications one could envision are e.g. a proximal anastomosis, distal anastomosis, or side-to-side anastomoses, in a customized pre-fabricated graft. Embodiments of the invention could also be incorporated into an anastomotic connector device design. Embodiments of the invention could further be envisioned as vascular grafts applications such as Coronary Artery Bypass Graft (CABG), dialysis access grafts and peripheral vascular applications.

Abstract: Graft devices are provided addressing a long need for off-the-shelf small diameter replacement vessels to overcome the drawbacks of currently available alternatives. As they are available off-the-shelf, the graft devices do not require additional surgery to harvest it such as for a vein graft. A porous nature of the graft devices enables restoration process, which results in new natural and patient-own tissue, in contrast to currently existing vascular prosthesis that can never fully heal. A built-in graft support device over-comes the limited kink-resistance that is typical for these kinds of (electro-spun) porous devices. A zigzag pattern with alternating laminating and non-laminating areas enables the incorporation of the graft support device without the need for additional suturing or connecting the inner and outer layer for good lamination, while maintaining adequate kinkresistance.

Abstract: Multi-layered engineered designs are provided for heart valve leaflets. The multiple layer designs have significantly improved mobility of the leaflets, without reduced durability, compared to an ordinary single-layer design. In addition, a folded double layer design also showed highly reduced the risk of fraying.

Abstract: A medical implant is provided that has a first and a second electrospun component with the same type of biodegradable electrospun polymers. In one example, the second electrospun component is separately manufactured from the first electrospun component. Furthermore, the implant is structured such that the first electrospun component and the second electrospun component are assembled or joint together by the same type biodegradable electrospun polymers as in the first electrospun component and the second electrospun component. The assembled implant is a porous, biodegradable medical implant capable of being replaced by naturally ingrown tissue over time upon implantation. Advantages are the avoidance of sutures and the problems associated with the use of sutures, capability of ETR, avoidance of the need for extra materials, allowance for more precise and reproducible assembled structures for which the process could be automated.
