|I.P. Brief:||This idesign for transurethral injection provides an increase pressure at the base of the needle. This design is intended to decrease the backflow of an injected solution, leading to better delivery of the desired solution, and elimination of the side effects of solution leaking outside of the intended site. |
|Summary of I.P.:||This device has been designed to provide the capability of inserting an injection needle at a substantially perpendicular angle substantially radially into and through the wall of a body cavity, most notably the prostate. The design includes the feature by which the injection needle can be inserted without backflow of the injected material out of the target and into adjacent tissue. The distal end portion of the needle delivery member compresses the tissue at and immediately surrounding the injection site. This compression tends to create a zone of increased pressure about the target portion of the internal bodily cavity wall. Also, the design keeps the injected material within compressed tissue at a location separated from the entry opening formed by the needle.
Advantages: This design more effectively delivers material to the prostate and enhances the retention capability of the tissue. Back flow of material is eliminated and therefore it is more efficacious and safe than current instruments.
