  • Methods of using compressible tubes for placing implants
    Patent number: 9610151
    Abstract: Medical delivery devices include a needle and a flexible compressible impermeable tube attached to the needle. The compressible tube has an open interior channel. The device is adapted to releasably hold a length of a medical implant in the open interior channel of the tube. The medical implant can be slidably inserted into the interior channel of the tube and is loosely held by the tube.
    Type: Grant
