Description

ABSTRACT:
The present invention relates to the direct delivery of therapeutic to a target tissue. In one embodiment a method for direct injection of plug forming material into a body tissue is provided. The method may comprise providing a catheter including an injection tube having a first channel, a second channel and a piercing tip. The first and second channels can be in fluid communication with a pressure source and a plug forming material. The injection tube may be slidably positioned in a pressure apron and moved from a first position to a second position so that the piercing tip extends beyond the tissue-mating surface in the second position to deliver the plug forming material.
