Abstract

A dispensing tip for e.g. a syringe dispensing an adhesive tissue sealant, having two rigid sections connected together by a flexible section. Preferably, although bendable, the flexible section has enough resilience that in the absence of external force the two rigid sections are held at a predictable angle to one another. In this way manual dispensing into hard to reach places during surgery is facilitated. This flexibility also facilitates use of the dispensing tip with a cannula.

Claims

1. A dispensing tip, comprising:

(a) a first rigid section having at least one lumen therethrough;

(b) a flexible section attached to the first rigid section; and

(c) a second rigid section attached to the flexible section, the second rigid section having an opening for dispensing material conducted through the lumen;

wherein the first rigid section has at least two lumens therethrough, wherein the second rigid element further comprises at least one static mixing element for mixing material conducted through the lumens prior to reaching the opening, and wherein the flexible section has a preset bend so as to urge the first and the second rigid sections towards a preset angle to one another.

2. The dispensing tip according to claim 1 wherein the preset angle is between about 20 and 45 degrees.

3. The dispensing tip according to claim 2 wherein the preset angle is about 30 degrees.

4. The dispensing tip according to claim 1 wherein the first rigid section is adapted to engage a dual syringe having at least two exit ports such that liquids dispensed from the exit ports each enter a different one of the lumens and are kept separate within the first rigid section.
