One or more longitudinally extending members with periodic raised wedges can be attached to a medical balloon. They can be attached with a fiber coating, a polymer coating, or other methods. A polymer matrix can be used to bond the longitudinally extending member to the surface of the balloon. The fiber coating can be, for example, a thread or mesh that secures the longitudinally extending member to the balloon. The medical balloon can be an angioplasty balloon, such as an off-the-shelf angioplasty balloon. ## Claims ### Claim 1 A method of manufacturing a serration balloon, comprising: inflating a medical balloon; dipping the medical balloon in the inflated state in a polymer matrix to form an over mold to the medical balloon; attaching a plurality of cutting blades along the surface of the polymer coated medical balloon in the inflated state, each cutting blade of the plurality of cutting blades comprising a strip of material with periodic raised wedges spaced along a length thereof; and retaining the plurality of cutting blades with retention layer over the plurality of cutting blades. ### Claim 2 (depends on 1) The method of claim 1, further comprising applying an adhesive to each cutting blade of the plurality of cutting blades prior to attaching the plurality of cutting blades along the surface of the polymer coated medical balloon. ### Claim 3 (depends on 1) The method of claim 1, further comprising forming each cutting blade of the plurality of cutting blades from a flat, planar piece of material. ### Claim 4 (depends on 1) The method of claim 1, wherein the medical balloon is dipped multiple times. ### Claim 5 A method of manufacturing a serration balloon, comprising: inflating a medical balloon; and dipping the medical balloon in the inflated state in a polymer matrix to form an over mold to the medical balloon and attaching a plurality of cutting blades along the surface of the polymer coated medical balloon in the inflated state, each cutting blade of the plurality of cutting blades comprising a strip of material with periodic raised wedges spaced along a length thereof. ### Claim 6 (depends on 5) The method of claim 5, wherein a retention layer is positioned over the plurality of cutting blades. ### Claim 7 (depends on 5) The method of claim 5, wherein a retention layer is applied after the cutting blades are attached to the polymer coated medical balloon. ### Claim 8 (depends on 5) The method of claim 5, wherein a second layer of balloon retains the cutting blades. ### Claim 9 (depends on 5) The method of claim 5, wherein the medical balloon comprises an angioplasty balloon. ### Claim 10 (depends on 5) The method of claim 5, wherein the polymer matrix comprises at least one of urethane, nylon, silicon or elastomeric material. ### Claim 11 (depends on 5) The method of claim 5, further comprising applying an adhesive to each cutting blade of the plurality of cutting blades prior to attaching the plurality of cutting blades along the surface of the polymer coated medical balloon. ### Claim 12 (depends on 5) The method of claim 5, wherein attaching a plurality of cutting blades along the surface of the polymer coated medical balloon further comprises adhering the cutting blades to the coated balloon with one or more points of attachment of the cutting blades. ### Claim 13 (depends on 5) The method of claim 5, wherein attaching a plurality of cutting blades along the surface of the polymer coated medical balloon further comprises adhering the cutting blades to the coated balloon with attachment along the entire length of the cutting blades. ### Claim 14 (depends on 5) The method of claim 5, wherein the cutting blades comprise strips of metal with a plurality of identical periodic raised wedges spaced along a length thereof. ### Claim 15 (depends on 5) The method of claim 5, further comprising forming each cutting blade of the plurality of cutting blades from a planar piece of material by cutting out the periodic raised wedges along a length of the planar piece of material. ### Claim 16 A method of manufacturing a serration balloon, comprising: inflating a medical balloon; dipping the medical balloon in the inflated state in a polymer matrix to form an over mold to the medical balloon and attaching a plurality of wedges along the surface of the dipped medical balloon in the inflated state. ### Claim 17 (depends on 16) The method of claim 16, further comprising retaining the plurality of cutting blades with retention layer. ### Claim 18 (depends on 16) The method of claim 16, further comprising applying a retention layer after the cutting blades are attached along the surface of the dipped medical balloon. ### Claim 19 (depends on 16) The method of claim 16, further comprising retaining the cutting blades with a second layer of balloon. ### Claim 20 (depends on 16) The method of claim 16, wherein attaching the plurality of wedges along the surface of the dipped medical balloon comprises gluing the plurality of wedges.
