A polymer sheath is formed about the helically coiled conductor such that the coil pitch of the unifilar helically coiled conductor is maintained.

The elastically-deformable member comprises a helically-coiled spring (11).

The conductor is comprised of a wire wound in a coil configuration with the wire comprised of a duplex titanium alloy.

This invention is a brachytherapy device (10) in the form of a radioactive coiled wire (10).

The devices are comprised of a flexible body, preferably formed from a helical wound spring.

The heater wire is spirally wound in a helix or double helix with both ends of the wire available for termination at one end of the conduit.

The polymer sheath is configured to increase a torque transmitting capacity of the helically coiled conductor.

A machine for producing a tubular product by means of a web material wound helically, comprising a spindle (4) and a feed and winding member (7) to feed and wind strips of web material (S1, S2) around said spindle to form the tubular product.

The second group is helically twisted around the first group with a cord twisting step.

A tube connecting the pump on the abutment to the inflatable collar is wrapped helically around the sleeve of the trocar.

In a method of producing a double-walled structure, such as a silencer for use in a ventilation duct system, use is made of an arrangement having a forming head (5) for forming helically-wound lock-seam tubing (2).

Lashing wire is released from the rotating drum and helically wrapped around the cable and the strand.

Advantageously, the masking element is a directly mounted wire (12) helically coiled in a recess (13, 14) provided in the form wire (3).

The construction includes a core tube (110, 210, 310), a second tube (130, 240, 320)helically disposed about the core tube, and a tubular jacket (140, 250, 330) surrounding the core tube.

Helices alone with large quantities of wire will produce similar results.
