Biodegradable antimicrobial films are provided that are solid at room temperature and substantially liquefy in situ after implantation into a mammal, such as a human patient. Methods of using the films to cover a medical device, such as a breast implant, prior to insertion into a subject are also provided.

An aortic stent graft includes a stent with a framework attached to a fabric tube by a plurality of suture ties. The fabric tube includes a plurality of discrete attachment areas that are at least partially surrounded by at least one permeable graft area. The fabric tube is one of a weave and a knit of thermoplastic yarn. Each of the suture ties associated with the discrete attachment areas at least one of penetrates through and encircles a respective one of the discrete attachment areas. The weave or knit of the discrete attachment areas is identical to that of the permeable graft area with an exception that a wall thickness of each of the discrete attachment areas is flattened relative to, and thinner than, a wall thickness of the permeable graft area.

A tubular structure fabricated by additive manufacturing from non-biological building material formulations, and featuring an elongated core, a shell encapsulating the core and an intermediate shell between the core and the shell. 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.
