20080228139 | Angioplasty Balloon With Concealed Wires - A balloon catheter having wires situated between an outer layer and a surface of a balloon is described. Each wire may be confined within an interior space of a pocket or encapsulated within a sheath. The pocket includes the outer layer and the balloon surface. The outer layer and balloon surface are unattached to allow the wire to slidably fit between therewithin. The pocket is selectively bonded to the balloon. The sheath includes a preformed shape that completely circumscribes the wire along the longitudinal and radial directions of the wire. The confined and encapsulated feature of the wires enable the wires to be atraumatic and remain spaced apart during treatment of calcification of a lesion. | 09-18-2008 |

20110048423 | Valve system for use with a flexible gas supply tube extending to a patient - Low pressure oxygen or other breathable gas is supplied from a tank or other source to a patient or other person through a flexible plastic tube, and a safety valve system is connected between the source and the tube. The valve system includes a valve member having a tubular outlet portion and supported for axial movement within a valve body having an inlet connected to the gas source. Fluid passages are formed within the valve member and valve body, and the valve member shifts axially to an open position in response to connecting the flexible tube to the tubular outlet portion of the valve member. The valve member shifts to a closed position in response to removing the tube from the tubular outlet portion, and the supply gas holds the valve member in the closed position. | 03-03-2011 |
