The strip is directed adjacent an elongate mandrel, such as beading, such that the length of the strip extends along the mandrel and the coating is disposed towards the mandrel. The strip is rolled at least partially around the mandrel such that the coating or surface modification is disposed inwardly towards the mandrel, and one or more strip-constrainment members are wrapped around the rolled strip. The directing, rolling, and wrapping steps may be substantially continuous to create one or more strip-mandrel-constrainment member subassemblies. ## Claims ### Claim 1 A method for making a tubular component of a catheter sized for introduction into a patient's body using a strip of polymer material including a length, a width, and a first surface comprising a surface modification, comprising: directing the strip adjacent an elongate mandrel such that the length of the strip extends along the mandrel and the first surface is disposed towards the mandrel; rolling the strip at least partially around the mandrel such that the first surface is disposed inwardly towards the mandrel; and wrapping a plurality of strip-constrainment members around the rolled strip, wherein the directing, rolling, and wrapping steps are substantially continuous to create one or more strip-mandrel-constrainment member subassemblies. ### Claim 2 (depends on 1) The method of claim 1, further comprising collecting the one or more strip-mandrel-constrainment member subassemblies helically on a take-up reel. ### Claim 3 (depends on 1) The method of claim 1, further comprising: periodically separating the rolled strip and mandrel wrapped by the constrainment members into multiple strip-mandrel-constrainment member subassemblies; and collecting the multiple strip-mandrel-constrainment subassemblies in a collection area. ### Claim 4 (depends on 1) The method of claim 1, further comprising encasing the one or more strip-mandrel-constrainment member subassemblies in a jacket. ### Claim 5 (depends on 4) The method of claim 4, wherein the one or more strip-mandrel-constrainment member subassemblies are encased in a jacket by extruding jacket material around the one or more strip-mandrel-constrainment member subassemblies. ### Claim 6 (depends on 4) The method of claim 4, wherein encasing the one or more strip-mandrel-constrainment member subassemblies in a jacket comprises: separating the rolled strip and mandrel wrapped by the constrainment members into multiple strip-mandrel-constrainment member subassemblies; and encasing each strip-mandrel-constrainment member subassembly in an individual jacket. ### Claim 7 (depends on 6) The method of claim 6, each strip-mandrel-constrainment member subassembly is encased in an individual jacket by: inserting a tubular member around the strip-mandrel-constrainment member subassembly; and heating at least one of the tubular member and the strip-mandrel-constrainment member subassembly to bond the tubular member around the strip-mandrel-constrainment member subassembly. ### Claim 8 (depends on 1) The method of claim 1, wherein the mandrel comprises a plurality of lengths of beading, and wherein the lengths of beading are fed sequentially into a guide to direct the lengths of beading adjacent the strip. ### Claim 9 (depends on 8) The method of claim 8, wherein the beading is substantially rigid and successive lengths of beading are spaced apart such that sections of the strip-mandrel-constrainment member subassemblies including rolled strip around the beading and wrapped in constrainment members are spaced apart from regions including rolled strip wrapped in constrainment members without beading. ### Claim 10 (depends on 1) The method of claim 1, wherein the strip of material is directed from a reel into a guide to place the strip adjacent to the mandrel, and wherein the guide rolls the strip at least partially around the mandrel. ### Claim 11 (depends on 1) The method of claim 1, further comprising: separating the one or more strip-mandrel-constrainment member subassemblies into multiple tubular bodies; directing a plurality of the tubular bodies into a guide; directing another strip of material into the guide to roll the strip at least partially around the plurality of tubular bodies; and wrapping one or more strip-constrainment members around the rolled strip and plurality of tubular bodies to create one or more multiple lumen tubular bodies. ### Claim 12 (depends on 1) The method of claim 1, wherein the surface modification comprises a coating on the first surface. ### Claim 13 (depends on 1) The method of claim 1, wherein the mandrel comprises a flexible beading material that is fed substantially continuously from a reel adjacent the strip. ### Claim 14 (depends on 1) The method of claim 1, further comprising: separating the one or more strip-mandrel-constrainment member subassemblies into multiple tubular bodies; directing a plurality of the tubular bodies into a guide; and wrapping one or more strip-constrainment members around the plurality of tubular bodies to create one or more multiple lumen tubular bodies. ### Claim 15 A method for making a catheter body sized for introduction into a patient's body, comprising: directing a strip of material substantially continuously from a reel to a guide to place the strip adjacent an elongate mandrel such that a length of the strip extends axially along the mandrel and a surface modification on a first surface of the strip is oriented towards the mandrel; substantially continuously rolling the strip at least partially around the mandrel such that the coating is disposed radially inwardly towards the mandrel; and substantially continuously wrapping one or more strip-constrainment members around the rolled strip to create one or more strip-mandrel-constrainment member subassemblies; and encasing the one or more strip-mandrel-constrainment member subassemblies in a jacket to create one or more tubular bodies. ### Claim 16 (depends on 15) The method of claim 15, further comprising collecting the one or more strip-mandrel-constrainment member subassemblies helically on a take-up reel. ### Claim 17 (depends on 15) The method of claim 15, further comprising: periodically separating the rolled strip and mandrel wrapped by the constrainment members to create multiple strip-mandrel-constrainment member subassemblies; and collecting the multiple strip-mandrel-constrainment subassemblies in a collection area. ### Claim 18 (depends on 15) The method of claim 15, wherein the one or more strip-mandrel-constrainment member subassemblies are encased in a jacket by extruding jacket material around the one or more strip-mandrel-constrainment member subassemblies. ### Claim 19 (depends on 15) The method of claim 15, wherein encasing the one or more strip-mandrel-constrainment member subassemblies in a jacket comprises: separating the rolled strip and mandrel wrapped by the constrainment members into multiple strip-mandrel-constrainment member subassemblies; and encasing each strip-mandrel-constrainment member subassembly in an individual jacket. ### Claim 20 An apparatus for making components of catheters sized for introduction into a patient's body and including one or more lumens, comprising: a strip of material having a width, a length wound around the reel, and a coating on a first surface of the strip; an elongate mandrel; a guide for directing the strip adjacent the mandrel and rolling the strip at least partially around the mandrel such that the coating is disposed inwardly toward the mandrel; a strip constrainment mechanism for wrapping a plurality of elongate constrainment members around the rolled strip after the rolled strip exits the guide to constrain the strip around the mandrel; and a drive mechanism for substantially continuously directing the strip and mandrel along the guide and strip constrainment mechanism to create one or more strip-mandrel-constrainment member subassemblies.
