A tube equipped electric wire, which is configured to be used in a catheter equipped with a catheter tube and be installed within the catheter tube, is composed of a tube including an outer surface, and one or more electric wires helically wound around the outer surface of the tube.

The present invention discloses a telescopic hose and the process technology thereof. The telescopic hose comprises an elastic support member that can be configured to conduct strong electricity; the support member comprises a first wire and a second wire, and the first wire and the second wire are arranged in a double helix structure in cooperation with each other; a hose wall that is wrapped around the outer side of the support member, and at least part of the hose wall between the first wire and the second wire forms a corrugated portion. Through the setting of the above structures, the hose can not only conduct strong electricity, but also stretch back and forth and turn at any angle. In addition, the hose structure is relatively simple, the amount of gas and liquid passing per unit time is larger.

The presently disclosed embodiments relate to insufflation and irrigation conduits for vessel harvesting systems and methods of their use. In particular, the present disclosure relates to a system having a combined cabling for providing gases, liquids, and/or electrical power to an attached medical device and method of use.

A cable is provided for suspending a down hole pump that has a core with at least one tube for the transport of fluid and at least one conductor covered with an insulation layer made of a high temperature resistant insulating material. The core is covered by a steel tape and a first layer of steel wires are positioned radially outside the steel tape in contact with the steel tape. The wires of the first layer of steel wires are positioned side by side around the core with no filler in between the steel wires and an outer layer made of heat resistant polymer covers the steel wires.

In particular, the present disclosure relates to a system having a combined cabling for providing gases, liquids, and/or electrical power to an attached medical device and method of use.

A cable system is provided which is configured with both electric wires and a fluid conduit running through the axial passage of a surrounding flexible sheath of the cable. The system allows for communication of electricity over the wires for electrical circuits and concurrent communication of a fire ignition suppressant fluid or gas through the fluid conduit, to all points in an electric circuit using the cable. One or both of a dye or scent can be included in the ignition suppressant fluid.
