Apparatus and methods are provided for making one or more tubular components of medical catheters or other tubular bodies using a strip of polymer material including a length, a width, and a first surface including a lubricious or other coating or surface modification. 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.

Inflatable medical devices and methods for making and using the same are disclosed. The devices can be medical invasive balloons, such as those used for transcutaneous heart valve implantation, such as balloons used for transcatheter aortic-valve implantation. The balloons can have high strength, fiber-reinforced walls.

The invention relates to a lining element for repairing a connection area between a main pipe and a branch pipe, the lining element including a layer of resin-absorbing material, wherein at least six flexible, expandable lining parts are connected to each other by at least six connections to form the lining element. To manufacture such a lining element the at least six flexible, expandable lining parts are provided and connected to each other by at least six connections to form the lining element.

A lining element for repairing a connection area between a main pipe and a branch pipe, comprising a layer of resin-absorbing material, wherein at least three flexible, expandable lining parts are connected to each other by at least three connections to form the lining element. Each lining part comprises a main pipe section and a branch pipe section, and side edges. The lining element is characterized in that the lining parts are connected to each other by connecting both side edges of the adjacent branch pipe sections and side edges of adjacent main pipe sections in a continuous fashion.
