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.
Claims14
A method for directly injecting plug forming material into body tissue comprising:
- providing a catheter including an injection tube having a first channel, a second channel, and a piercing tip;
- delivering plug forming material to the first and second channels with a pressure source;
- slidably positioning the injection tube in a pressure apron having a tissue mating surface;
- and
- moving the injection tube between first and second positions to form a void in the body tissue and to inject the plug forming material into the void.
A method of directly injecting plug forming material into body tissue comprising:
- providing a catheter with a lumen and a catheter piercing tip;
- coupling a pressure apron to the catheter, the pressure apron surrounding the catheter and having a tissue-mating surface adaptable to sealably engage a target tissue, the catheter slidable within the pressure apron;
- slidably positioning an injection tube within the lumen, the injection tube having at least one first channel and an injection tube piercing tip;
- and
- delivering plug forming material to the at least one first channel, wherein the injection tube is extendable and retractable from the lumen to form a void in the target tissue and to inject the plug forming material into the void.
A method for directly injecting plug forming material into body tissue comprising:
- providing a catheter having a lumen, at least one channel feed, and a pressure apron surrounding the lumen;
- slidably positioning an injection tube within the lumen, the injection tube having first and second channels and an injection tube piercing tip;
- and
- delivering plug forming material and therapeutic to the channels via the at least one channel feed,
- wherein the injection tube is extendable and retractable from the pressure apron to form a void in the body tissue and to inject the plug forming material and therapeutic into the void.
