Abstract
A pressure apron for insitu plug formation is provided. In one embodiment an injection tube having a first channel and a piercing tip is provided, the first channel in fluid communication with a pressure source. In this embodiment, the injection catheter may also include a pressure apron with a tissue-mating surface. In another embodiment a medical kit for delivering a therapeutic is provided. This medical kit may include a catheter having a channel and a piercing tip, the piercing tip in fluid communication with a pressure source and slidably placed in the channel. The catheter in this embodiment may include a pressure apron with a tissue-mating source while a therapeutic may be included with the kit.
Claims25
An injection catheter for direct injection into a body tissue comprising:
- an injection tube having a first channel and a piercing tip, the first channel in fluid communication with a pressure source;
- and
- a pressure apron,
- the injection tube slidably placed in the pressure apron and moveable from a first position to a second position,
- the pressure apron having a tissue-mating surface,
- the piercing tip extending beyond the tissue-mating surface in the second position.
An injection device for direct injection into a body tissue comprising:
- a catheter with a lumen;
- a pressure apron coupled to the catheter and surrounding the lumen;
- and,
- a piercing tip retractably positioned within the lumen and extendable from the pressure apron,
- the pressure apron having a tissue-mating surface adaptable to sealably engage a target tissue.
A medical kit for delivering a therapeutic comprising:
- a catheter having a channel, and a piercing tip, the piercing tip in fluid communication with a pressure source the piercing tip slidably placed in the channel;
- a pressure apron coupled to the catheter and having a tissue-mating source;
- and
- a therapeutic.
A system for preventing leakage of material from a body tissue during the injection of a therapeutic comprising:
- a catheter with a lumen;
- a pressure apron surrounding the lumen;
- and,
- a piercing tip retractably positioned within the lumen,
- the pressure apron having a tissue-mating surface.
