Abstract

An improved fibrin glue delivery system is disclosed. The delivery system is comprised of a pair of syringe tubes which can be actuated by plungers simultaneously or independently, a connecting member which holds the syringe tubes in parallel alignment and a unique needle assembly which ensures the components in the syringe bodies will not be comingled until they reach the treatment site. The unique needle assembly also permits the user to manipulate the needles to enhance visibility when the surgeon is working through a speculum or when direct access is difficult.

Claims

1. A delivery system for applying to a treatment site a tissue adhesive having a pair of components which must be kept separate from each other until they reach the treatment site, said delivery system comprised of:

(a) a first syringe body for storing a first tissue adhesive component and a second dyringe body for separately storing a second tissue adhesive component;

(b) a separate piston type plunger, having an elongated shaft, a head and a push flange, associated with each of said syringe bodies for expelling from each of said syringe bodies its associated tissue component;

(c) a hypodermic needle, having an elongated portion, associated with each of said syringe bodies;

(d) means for connecting said syringe bodies to said hypodermic needles so that each of said tissue adhesive components is afforded an independent flow path from its syringe body, through said connecting means and through its hypodermic needle preventing the comingling of said first and second tissue adhesive components before they reach the treatment site;

(e) a hollow sleeve surrounding the elongated portions of said hypocermic needles retaining said elongated portions in parallel registration with respect to each other and forming a structure which permits the needles to be bent simultaneously into a desired shape; and

(f) means for retaining said syringe bodies in parallel alignment.

2. The apparatus of claim 1 further including a removable connecting clip member to be secured to each push flange so that each piston type plunger may be actuated simultaneously when desired.

3. The apparatus of claim 1 wherein said means for retaining said syringe bodies in parallel alignment includes:

(a) open faced semi-cylindrical channels for receiving and retaining said syringe bodies; and

(b) a flange assembly including flange members which project in a plane perpendicular to the semi-cylindrical channels so that the apparatus can be comfortably held by the user in a variety of orientations.
