10252309 · 2019-04-09 · ·

A tie bar tensioning system that allows a bending machine operator to removably couple an upper end of a bend die post of the bending machine to a base of the bending machine via a tie bar, and to lock the tie bar in a tensioned position. The tensioning system includes a stationary member and a rotatable member, each with aligned tie bar passages for receiving the one end of the tie bar. Both the stationary member and the rotatable member include respective engagement surfaces, with the rotatable member engagement surface being rotatable relative to the stationary member engagement surface between a released position and a tensioned position whereat the rotatable member is selectively lockable. The rotation of the rotatable member with the stationary engagement surface in engagement with the stationary engagement surface longitudinally displacing the rotatable member relative to the stationary member.

In-line hydraulic crimp tool

A crimp tool having jaw members joined in a tongue-in-groove connection held in place by a locking pin. Each jaw member being tapered and including weight reducing pockets defined in respective sidewalls. Each jaw member includes a locking tab on an outside edge that mates with a respective locking tab opening in the neck of the tool. When the locking pin is removed, the jaws of the tool separate and rotate away from one another until their respective locking tabs engage their respective locking tab opening, thereby holding the opened jaws in the neck of the tool.

Radical compression apparatus and method of incrementally compressing an article using same
09956604 · 2018-05-01 · ·

A radial compression mechanism incorporates an introduction funnel that truncates down to a cylindrical cavity for radial compressing articles. The introduction funnel facilities the loading of an article into the cylindrical cavity and enables incremental radial compression of articles, such as stents. The radial compression mechanism employs a plurality of compression dies that are configured radially about the cylindrical cavity and move in unison to cause the cylindrical cavity to open or close. The compression dies are coupled with a base and drive mechanism for moving them in unison. A method of loading a delivery catheter with a radially compressed article, such as a stent, includes positioning a delivery catheter over a compressed portion of an article that extends from an exit end of the cylindrical catheter. One or more drive mechanism may be used to automatically and incrementally load a compressed article into a delivery catheter.
