Trimedyne Cleared to Sell Laser Needle

Trimedyne Inc. said Thursday it has received regulatory clearance to begin marketing a new laser needle used in treating herniated lumbar disks.

The Irvine company’s shares moved up $1.22 to $2.59 after the announcement.

The company said its OmniTip side-firing laser needle received clearance from the Food and Drug Administration. The device vaporizes a portion of a herniated lumbar spinal disk in a minimally invasive procedure, reducing the volume of the disk.
