Patent number: 8474490Abstract: A slip brass nipple includes a tubular brass body that may be approximately 6 inches long. The apparatus includes a threaded proximal end, a non-slip gripping portion and an open distal end n. The open distal end includes an internal stop to allow a copper pipe to slip in and terminate at a predetermined distance such that the gripping portion may be used to tighten onto a female tube fitting. The apparatus advantageously enable galvanized and copper pipes to be connected together while significantly reducing the risk of galvanic corrosion caused by a dielectric reaction between the galvanized steel and copper pipes. The slip brass nipple may be manufactured in ½, ¾, 1, 1¼, 1½ and 2 inch diameters and may be manufactured according to brass material regulations in the industry.Type: GrantFiled: February 27, 2012Date of Patent: July 2, 2013Inventor: Juan M.

Patent number: 8439084Abstract: A flexible conduit for insertion into a body lumen comprises a plurality of elements coupled end to end to define a conduit lumen. A first one of the elements includes a male portion and a female portion. A second element includes a female portion having an inner surface configured to engage a male portion of an outer surface of the first element to form a first ball joint. A third element includes a male portion, an outer surface of the male portion of the third element configured to engage an inner surface of the female portion of the first element to form a second ball joint. The male and female portions of the first element are adapted to frictionally engage the female portion of the second element and the male portion of the third element to establish a rigid connection therebetween.Type: GrantFiled: September 23, 2011Date of Patent: May 14, 2013Assignee: Boston Scientific Scimed, Inc.Inventor: Stephen J.

Publication number: 20130068341Abstract: The present invention is to provide a tube for cable sheath and the cable sheath using the same. The front end of each tube is connected to the rear end of another one. Two side plates are connected to another tube. A cable is received in the cable sheath. Thereby, when a brake cable is received in the cable sheath, the side plates are connected to another tube so as to restrict one of the bending direction degree of the cable that can avoid the cable sheath being bended in all direction. It is important that the side plates can protect the connecting point of each tube quite well and enhance the structure intensity of the whole cable sheath. After standardizing the specification of the present invention, it can be connected to many kinds of products. The present invention has abundant variability and achieves the best efficacy.Type: ApplicationFiled: September 18, 2011Publication date: March 21, 2013Inventor: Yuan-Hung WEN
