An inflatable device for use in a biological body, comprising: a balloon defining a longitudinal axis having a longitudinal axis length, the balloon comprising a fiber having a fiber length, wherein the fiber length is from about 175% to about 300% of the longitudinal axis length, wherein the fiber is parallel with the longitudinal axis, and wherein the balloon has a closed longitudinal end. 2. The device of claim 1, wherein the balloon comprises a wall comprising a layer, and wherein the fiber is in the layer, and wherein the layer comprises a resin contacting the fiber. 3. The device of claim 1, wherein the balloon comprises a wall comprising a first layer and a second layer, and wherein the fiber is in a second layer, and wherein the first layer is radially inside of the fiber, and wherein the first layer is leak-proof. 4. The device of claim 1, wherein the balloon comprises a wall comprising a first layer and a second layer, and wherein the fiber is in a second layer, and wherein the first layer is radially outside of the fiber, and wherein the first layer is MMA-resistant. 5. An inflatable device for use in a biological body, comprising: a balloon comprising a wall comprising a reinforcement fiber, wherein the balloon has a a distal terminal end having a distal-most point oriented substantially along a longitudinal axis of the balloon, and wherein the balloon has no longitudinal through-lumen extending through the proximal terminal end and through the distal terminal end, and wherein the reinforcement fiber is in a matrix, wherein the reinforcement fiber is oriented parallel with the longitudinal axis of the balloon, and wherein the reinforcement fiber extends around the distal-most point of the distal terminal end of the balloon. 6. The device of claim 5, wherein the balloon has a balloon area and wherein the fiber is on about 50% or more of the balloon area. 7. The device of claim 5, wherein the matrix comprises a thermoplastic material. 8. The device of claim 5, wherein the matrix comprises a urethane. 9. The device of claim 5, wherein the matrix comprises a polyether block amide. 10. The device of claim 5, wherein the matrix comprises a polyamide. 11. An inflatable device for use in a biological body comprising: a balloon comprising a wall comprising a plurality of fiber tape strips;wherein the balloon has a closed distal end, and wherein the plurality of fiber tape strips overlay one another such that the fibers therein meet at regular angles at the closed distal end. 12. The device of claim 11, wherein the regular angles between the fibers are greater than or equal to about 30 degrees. 13. The device of claim 12 wherein the regular angles between the fibers are greater than or equal to about 45 degrees. 14. The device of claim 12, wherein the regular angles between the fibers are about 60 degrees. 15. The device of claim 11, wherein at least one of the fiber tape strips has a first length, and wherein the first strip along the first length has a first width, and wherein the first strip has a second length adjacent to the first length, and wherein the first strip along the second length has a second width larger than the first width, and wherein the first strip along the second length tapers to the first strip along the first length, and wherein the first strip has a third length adjacent to the second length, and wherein the first strip along the third length has a substantially round shape. 16. The device of claim 15, wherein the at least one of the fiber tape strips has a fourth length adjacent to the third length, and wherein the first strip along the fourth length has a fourth width, and wherein the first strip has a fifth length adjacent to the fourth length, and wherein the first strip along the fifth length has a fifth width smaller than the fourth width, and wherein the first strip along the fourth length tapers to the first strip along the fifth length. 17. The device of claim 11, wherein the fiber in each of the fiber tape strips are uni-directional.
