International Classification:

A61M 3700

US Classification:

604 9501

Abstract:

A steerable catheter having a segmented tip formed from materials of differing hardnesses. A tip segment formed of softer material provides improved steerability, while an adjacent harder segment provides improved resistance against steering wire pull-through. Wear-resistant sleeves and a coined loop portion of steering wire provide additional resistance against steering wire pull-through. A tip fabrication method is also disclosed. The catheter includes a one-piece inlet housing with integral mounting fins for attachment to the catheter housing.

Appl. No.:

8/168057

Inventors:

Robert C. Biggs - Roswell GA

International Classification:

F24D 900

US Classification:

126101

Abstract:

A combination hot air furnace and hot water heater (10) having a furnace (20), a gas flow control valve (40) and a hot water heater (60) constructed as an integral assembly. Furnace (20) has furnace gas burner (33) supported below furnace heat exchanger (32). Furnace heat exchanger (32) is supported within conduit (24) through which air is passed for heating. Gas flow control valve (40) is sealingly mounted upon the top outlet (36) of furnace heat exchanger (32), and may selectively direct the heat of combustion from furnace gas burner (33) toward water tank (62) for heating water within the water tank. Gas flow control valve (40) may also seal off furnace heat exchanger (32) from the flow control valve and draw outside combustion air into valve body (42) through side wall opening (48) for providing combustion air for water tank gas burner (64).

International Classification:

US Classification:

Abstract:

An endocoupler system having an endocoupler (110) and a myeloscope (210). The present invention relates to an endocoupler system. More particularly, the present invention relates to an endocoupler system consisting of an endocoupler connected to a myeloscope. The present invention is a system to directly view the pathology of the epidural space in the lower spine region using a miniature endoscopic catheter device. This device is currently used by physicians to diagnose and treat patients who suffer from chronic low back pain. The present invention consists of a developed medical procedure, disposable procedure access kit, multi-lumen steerable catheter (Video Guided Catheter), small fiber optic endoscope (Myeloscope), endocoupler (Endocoupler), light source, and camera system. A major feature of the invention is the ability to orientate the viewing plane with respect to the image transmitted through the image fiber bundle by rotation of the image fiber coupler in a plane that is normal to the central optical axis of the objective lens assembly and image fiber coupler. This is accomplished in the present invention which is designed permitting the endocoupler to rotate allowing the image fiber coupling to be oriented at the connection point to the endocoupler.
