Abstract
Medical constructs with collagen fibers and gelatin and related collagen fibers. The collagen fibers can be derived from extruded soluble dermal collagen and can include a gelatin film attached to the at least one collagen fiber. The gelatin film can include one or more minerals and has a gelatin concentration of between about 0.1% to about 40% weight per volume.
Claims29
A medical device, comprising:
- a tube with a wall surrounding an axially extending cavity, the wall having at least one wound collagen fiber derived from extruded soluble dermal collagen and a gelatin film attached to the at least one collagen fiber, the gelatin film comprising one or more minerals and having a gelatin concentration of between about 0.1% to about 40% weight per volume, wherein the at least one wound collagen fiber has a pattern with a number of revolutions about the tube cavity with overlying intersecting segments over at least a major portion of a length of the tube.
At least one elongated collagen fiber, wherein the at least one collagen fiber has a length of between about 1 m to about 100 m and is at least partially coated with a gelatin film comprising one or more minerals and having a gelatin concentration of between about 0.1% to about 40% weight per volume.
An implantable medical device comprising:
- a tube with a wall surrounding an axially extending cavity, the wall having at least one collagen fiber with a continuous length arranged in a pattern having a number of revolutions about the tube cavity with overlying intersecting segments over at least a major portion of a length of the tube;
- a gelatin film attached to the at least one collagen fiber, the gelatin film comprising one or more minerals and having a gelatin concentration of between about 0.1% to about 40% weight per volume;
- at least one layer of collagen film attached to the at least one collagen fiber residing over the gelatin film;
- and
- at least one layer of collagen film attached to the at least one collagen fiber residing under the gelatin film.
