Patent CA-2172231-A1 (CA)
Title: Box hanger and method
Inventor: LAUGHLIN RAYMOND SCOTT
IPC: H02G3/12
Filed: 1996-03-20
Abstract: The box support system uses a channel shape one piece slotted strut and a twist spring snap clip.  The strut ends are bent opposite the legs of the channel to form spring separable fingers which snap over and lock behind the bulb on the stem of a Tee bar. The slots of the strut are centered transversely providing two equal shelves on each side. The slots are positioned asymmetrically longitudinally so that a box may be supported anywhere between spaced Tee bars.  If it will not fit because of unslotted areas, it will fit if the strut is turned end-for-end.  The spring snap clip includes a V-shape body forming a pointed nose.  The two legs of the body have shouldered necked portions adjacent outwardly extending feet which terminate in upwardly extending toe tabs. Opposite shoulders at the neck includeoppositely angled spring locking talons.  Box assembly is obtained by inserting the clip through the center knockout in the back of a box with the toe tabs entering two smaller holes on each side of the knockout. Then using the box as a handle for the clip the clip is inserted into the slot and the clip-box assembly is twisted 90°. The talons rake over the shelves on each side of the slot limiting the twisting to one direction until the toe tabs projecting slightly through the box back wall snap into the slot.

Patent CA-2175100-A1 (CA)
Title: Delivery catheter for electrolytically detachable implant
Inventor: MILLS TIMOTHY
IPC: A61N1/20
Filed: 1996-04-26
Abstract: The invention involves a catheter for introducing a delivery member such as a guidewire having an implant coupled thereto via an electrolytically disintegratable link that is coupled to the anode of a power supply having an anode and a cathode. The catheter comprises an elongated tubular member having an outer surface, proximal and distal end portions, a lumen extending between those portions, an electrode and a conductor. The electrode is disposed within the outer surface of the tubular member in the vicinity of the distal end portion and has a surface that faces and communicates with the lumen. The electrode is electrically coupled to the conductor which, in turn, is adapted for coupling to the power supply cathode such that when the electrolytically disintegratable link is placed in an ionic solution, such as can be found in an aneurysm, and positive current is provided from the power supply to the link, current from the link may return to the cathode of the power supply via the electrode. With this construction, the electrode is shielded from endolumenal structures which could otherwise increase the resistance in the current path from the sacrificial link to the electrode. The positioning of the electrode in the catheter as described above allows a reproducible impedance path from the electrode to the detachment zone, thus reducing detachment time variability.
