A pipe adapter includes a first tubular element having a first portion, a second portion axially adjacent the first portion, and a securing portion adjacent an end of the second portion opposite the first portion, the second portion defining a socket; a second tubular element having a first portion and a second portion axially adjacent the first portion, the first portion defining a distal end sized for insertion into the socket and having a radially extending stop; an annular sealing member. The securing portion is formed integrally with the second portion of the first tubular element and has a flange portion contacting the stop to secure the second tubular element axially relative to the first tubular element while also allowing the second tubular element to rotate relative to the first tubular element.

A connecting rod comprises a convex elongated body around a longitudinal axis of symmetry and two connecting ends for connecting to adjacent structures. The connecting rod includes two shells with two longitudinal edges that are assembled in these edges and that each have a base of at least one shell web including continuous shell fibers primarily parallel to this axis of symmetry and impregnated with a thermoplastic shell matrix. The connecting rod incorporates at least one assembly web wound around and along the shells, and assembly fibers primarily inclined relative to the axis and impregnated with a thermoplastic assembly matrix remelted in contact with the shell matrix.

A cured in place liner system and associated connections and methods are disclosed. The cured in place pipe system forms a completely rehabilitated, stand-alone, fluid-tight flow path between upstream and downstream portions of an existing pipe system. The rehabilitated flow path is stand-alone in that the liner system does not rely on structure of the portion of the pipe system through which the liner system is installed to define the fluid-tight flow path. The flow path between upstream and downstream portions of the liner system is defined by and made fluid-tight solely by components of the rehabilitation system such as cured in place liners and couplers. The portion of the pipe system through which the rehabilitation system is installed merely provides a path (e.g., through the ground) through which the cured in place liner system can be inserted. After the cured in place liner system is installed, the liner system forms a fluid-tight flow path between an upstream portion of the pipe system and a downstream portion of the pipe system. Various types of connections may be used. In addition, various types of methods may be used in forming the connections, such as using a mold to cure connecting sections of the cured in place liners in desired configurations (e.g., having a generally circular outer profile) for forming connections with the liners.

A moldable material shaping system for shaping a moldable material, the system comprising a thermal transfer mold having an internal cavity configured to receive a moldable material, the internal cavity further comprising an internal mold shape, a thermally controlled heat source subsystem configured to heat the thermal transfer mold and the moldable material received in the thermal transfer mold thereby reshaping the moldable material to a deformed moldable material shape conforming to the internal mold shape. Some embodiments further comprise a cooling source subsystem configured to cool the thermal transfer mold and stabilize the moldable material inside the thermal transfer mold to maintain the deformed moldable material shape. Methods of molding a moldable material are also disclosed.

Disclosed herein are expandable introducer sheaths and methods of making and using the same. The sheaths minimize trauma to a patient's vasculature by allowing for temporary expansion of a portion of the sheath to accommodate passage of a delivery system for a cardiovascular device, then return to a non-expanded state after the passage of the device. The sheath includes an elongated annular member having longitudinally extending channels that facilitate the sheath's temporary expansion. The channels are positioned in such a way that, upon expansion, they enable the movement of protruding contact surfaces toward the inner and outer surfaces of the annular member, reducing friction between the surface and the passing device. Some embodiments of the expandable sheath include an elastic outer layer that pushes the protruding contact surfaces back towards their original positions after the passage of the device.

Method for fabricating a catheter including providing an inner tubular member formed from a first polymeric material, the inner tubular member having a distal section, a distal end, and a lumen defined therein by a first inner diameter; necking down at least a portion of the distal section of the inner tubular member to form a necked tip having a second inner diameter; and removing a portion of polymeric material from an inner surface along the necked tip to define a third inner diameter for the necked tip. The method can include positioning the distal section of the inner tubular member in a balloon having a working length, a distal neck, and a distal leg, with the distal end of the inner tubular member extending distally beyond a distal end of the distal leg, and coupling the distal leg of the balloon to at least a portion of the distal section of the inner tubular member.
