A medical device includes a balloon expanded scaffold (or stent) crimped to a catheter having a balloon. The scaffold is crimped to the balloon by a process that includes using protective polymer sheaths or sheets during crimping, and resetting the sheaths or sheets during the crimping to avoid or minimize interference between the polymer material and scaffold struts as the scaffold is reduced in size. Balloon pressure is adjusted when the polymer material is reset.

A pipe deployment system that includes a vehicle or trailer. A coil of pipe couples to the vehicle or trailer. A rerounder system is supported by and couples to the vehicle or trailer. The rerounder system changes a cross-sectional shape of the pipe. The rerounder system rotates relative to the vehicle or trailer to facilitate loading of the coil, and un-loading of the product on the coil.

Electrically powered crimp tools are described. Also described are methods of operating the tools and methods of crimping. The tools include a housing, an electric motor, a roller screw assembly, and a jaw assembly. In particular versions of the tools the jaw assembly includes a cam linkage member that is manually displaced by a user to more easily open the jaws after performing a crimp.

A bending method and a bending device, wherein a composite bar comprising a bundle of reinforcing fibres embedded in a polymer matrix is bent at a bending point. To make it bendable, the composite bar is heated locally at the bending point using an ultrasonic device with a sonotrode. After the bending point has been heated, an infeeding movement between the composite bar and the sonotrode is used to deform a region of the composite bar at the bending point to create a deformed portion of which the outer dimensions are different from the outer dimensions of the bar portions of the composite bar adjoining the bending point. The two bar portions are then moved or angled away in relation to one another, and so the composite bar is curved at the bending point. Once the desired bending has been achieved, the composite bar is cured at the bending point.

Electrically powered crimp tools are described. Also described are methods of operating the tools and methods of crimping. The tools include a housing, an electric motor, a roller screw assembly, and a jaw assembly.

A hose forming apparatus is provided that can separate with minimum shape deformation when separating a hose after forming is complete. The hose shaping apparatus includes an insertion path configured to insert a hose in a longitudinal direction and to have a shape corresponding to that of the hose to be formed; and a fixing portion configured to fix the hose inserted into the insertion path, wherein the insertion path forms a straight insertion portion configured to insert a straight segment of the hose to be formed and a bending insertion portion configured to insert a bending segment of the hose, and the bending insertion portion has an additional angle further bent by 15 to 35 than an angle of the bending segment.

The scaffold is crimped to the balloon by a process that includes using protective polymer sheaths or sheets during crimping, and resetting the sheaths or sheets during the crimping to avoid or minimize interference between the polymer material and scaffold struts as the scaffold is reduced in size. Balloon pressure is adjusted when the polymer material is reset.

An embodiment for disposing a sleeve on a fluid conduit includes positioning a sleeve through lead rollers, pressing sleeve edges to flatten the sleeve against its normal geometry, aligning the flattened sleeve with opposing guide channels defined in an passage through a sleeve guide, feeding the sleeve through the passage, and compressing the sleeve in the passage, letting the edges of the sleeve ride against the guide channels to open the sleeve. A length of the compressed sleeve exiting the guide may be cut using a heated device that fuses the sleeve material, leaving the sleeve clear to receive a fluid conduit. A collar may be disposed around an end of the cut sleeve and over the conduit, then compressed, with an end of the sleeve captured between the collar and end of the conduit. This compressing may define at least one raised portion in the collar.

Methods and devices of shaping a part during a manufacturing process. The devices include a contouring unit that applies a force to one or more contact points of an index section of the part, and a measuring unit that measures a shape of a virtual index section of the part. The methods include applying a force to the index section of the part and shaping the separate the virtual index section of the part. The shaping can shape the virtual index section to a target shape.

A weather strip including a bottom wall, a first lateral wall and a second lateral wall and in which an angle between the bottom wall and the first lateral wall is constant and an angle between the bottom wall and the second lateral wall is partially varied in a longitudinal direction is manufactured. The method includes: a first step of pre-forming the angle of the first lateral wall and the angle of the second lateral wall to be constant and equal to or larger than final maximum angles; a second step of regulating a boundary between the bottom wall and the second lateral wall from moving toward the first lateral wall by a regulating member; a third step of partially varying the angle of the second lateral wall by a movable roller; and a fourth step of forming the angle of the first lateral wall by a fine-movable roller.
