Advantageously, said textile component comprises multifilament yarns and/or spun yarns made of fibers, at least a part of the filaments and/or fibers each having a diameter less than or equal to 25 micrometers.

A carbo nanofiber nerve scaffold includes a cylindrical helix, a bundle of aligned carbon nanofiber yarns, and a carbon nanofiber sheet. The cylindrical helix includes a surgical suture material, and the cylindrical helix defines an interior of the carbon nanofiber nerve scaffold. The bundle of aligned carbon nanofiber yarns is disposed within the interior of the cylindrical helix. The carbon nanofiber sheet is disposed around the cylindrical helix on a side of the cylindrical helix opposite of the interior.

A laser is used to form openings within a graft material to selectively enhance permeability of a prosthesis for tissue integration therein. A feature of utilizing a laser to create the openings for tissue integration builds from its tunability. More particularly, the laser precisely places openings in any pattern and location, and on any textile that forms the graft material. Further, the power and focus of the laser is precisely adjusted to control the diameter and shape of the openings. All parameters of the openings can be controlled at will, allowing for the opportunity to selectively enhance and optimize the permeability of the graft material in a vessel.

A vascular prosthesis (1) for connection to a natural cardiovascular system, includes a volume chamber (2), wherein the volume chamber (2) has, in a blood pressure range below a pressure threshold value D, a pressure-expansion behavior substantially corresponding to the pressure-expansion behavior of a natural blood vessel, while the volume of the volume chamber (2), depending on the pressure, increases by at least 10 cm.sup.3 in a blood pressure range above the pressure threshold value D. The vascular prosthesis (1) is configured as a textile tube, wherein the textile tube includes in the region of the volume chamber (2) an elastic yarn having a core made from silicone yarn around which a yarn made from polyethylene terephthalate (PET) is wrapped.

The techniques of this disclosure generally relate to a variable permeability layered prosthesis including an impermeable outer layer and a permeable inner layer. The impermeable outer layer is well suited to seal a dissection opening of a dissection. The permeable inner layer allows fluid to enter into a dead space between the impermeable outer layer and the permeable inner layer. The fluid in the dead space coagulates in the dead space providing a media for tissue growth into the prosthesis. The ability of tissue to integrate into the prosthesis provides biological fixation of the prosthesis in vessels and prevents endoleaks and migration of the prosthesis.

Resorbable implants comprising poly(butylene succinate) and copolymers thereof have been developed. The implants implants are preferably sterilized, and contain less than 20 endotoxin units per device as determined by the limulus amebocyte lysate (LAL) assay, and are particularly suitable for use in procedures where prolonged strength retention is necessary, and can include one or more bioactive agents. The implants may be made from fibers and meshes of poly(butylene succinate) and copolymers thereof, or by 3d printing, and the fibers may be oriented. Coverings and receptacles made from forms of poly(butylene succinate) and copolymers thereof have also been developed for use with cardiac rhythm management devices and other implantable devices. These coverings and receptacles may be used to hold, or partially/fully cover, devices such as pacemakers and neurostimulators. The coverings and receptacles are made from meshes, webs, lattices, non-wovens, films, fibers, and foams, and contain antibiotics such as rifampin and minocycline.

A hydraulic muscle comprises a hollow carbon nanotube (CNT) yarn tube comprising: a plurality of CNT sheets twisted and wrapped in form of a hollow tube; and a binding agent infiltrated in the plurality of CNT sheets that binds the plurality of the CNT sheets together. A method of manufacturing a hydraulic muscle comprises: twisting and wrapping a plurality of carbon nanotube (CNT) sheets around a core fiber; infiltrating a binding agent in between the plurality of CNT sheets, wherein the binding agent binds the plurality of the CNT sheets together; and removing the core fiber from the plurality of CNT sheets.
