Definitions

• This invention relates to an applicator for the directional delivery of one or more materials to a desired internal site in a human or animal.
• a directional application system for applying one or more components to a desired internal site in a human or animal within a range of angular directions.
• the present system comprises a source of the components; means for fluid communication integral at a first end with the source of components and at a second end with a directional nozzle; and a directional nozzle comprising an inner tube of resilient material integral at a first end with the second end of the fluid communication means and having a nozzle at a second end, the second end being bent to the maximum angle within the desired range of directions; and an outer tube of a material more rigid than the inner tube and having an opening at one end to allow the inner tube to slidably project through the opening, whereby the amount of projection of the bent end of the inner tubing through the opening determines the angular direction of the nozzle.
• Figure 1 shows a section of resilient tube with the bent or curved nozzle end.
• Figures 2-4 illustrate the different range of angular delivery possible depending upon the extent to which the resilient tube is projected out of or retracted into the second end of the rigid tube.
• Sliding means can be provided at or near the first end of the rigid tube.
• the device of the present invention may be used to deliver materials endoscopically, i.e., via a body opening or duct to an organ, or through a surgical opening typically fitted with a trocar, e.g., laparoscopically or thorascopically, that is, into the abdominal or thoracic cavity.
• the invention comprises a directional dispensing or delivery device comprising an inner tube of a resilient material integral at a first end with a source or sources of the one or more materials to be delivered and having a nozzle at a second end.
• the second or nozzle end of the resilient material is bent or curved to the maximum angle within a desired range of angular directions for delivery of the materials.
• the inner tube is positioned slidably within an outer tube of a more rigid material such that the user can hold a first end of the rigid outer tube (which may be formed into a convenient handle) and such that the second end of the resilient tube can extend out of an opening at a second end of the rigid tube.
• the second end of the more rigid tube is positioned in the vicinity of the site to receive the desired materials, e.g., through the trocar.
• Means are provided to slide the resilient tube within the rigid tube so as to vary the length of the resilient tube projecting beyond the second end of the rigid tube. In doing this, the bent or curved nozzle (second) end of the resilient tube will assume, or be positioned at, varying angles to deliver or dispense the materials to a desired internal location.
• the resilient inner tube is in fluid communication directly or indirectly with sources of the components to be delivered.
• indirectly is meant that the resilient tubing is in fact connected to a separate tubing or conduit which is, in turn, connected to the sources.
• the source of components are at a remote location and connected by tubing. This means that the user does not have to hold the sources of components in his/her hand and greater ease of use is provided. This is disclosed in WO 98/20931 and WO 97/20585 incorporated herein by reference.
• the sources of components are in a remote location as part of a mechanical or electromechanical drive unit to deliver the components from the sources to, and out the nozzle of, the present device.
• Delivery of the components from the sources, through the means for fluid communication and out of the directional nozzle, can be accomplished using a foot pedal which signals the drive unit.
• the present device may incorporate a handle for the user which may further include an actuator, button or trigger to actuate dispensing of the components.
• the device of the present invention can be incorporated onto the delivery end of any medical component applicator, such as double barreled syringes, known in the art to apply fibrin sealants.
• the dimensions of the outer tube are adapted for their intended purpose.
• the outer tube needs to be comparable to other endoscopic tubing for insertion into canals, e.g., esophagus, colon, etc., or into other body apertures or cavities.
• the laparoscopic use the outer tube needs to fit through a trocar.
• the outer tube (with the inner tube withdrawn as in Figure 2) is inserted into the area where component delivery is desired. Thereafter, the inner tube is extended sufficiently to provide the desired angular directional spray or delivery of components as shown in Figures 3 and . This can be used in conjunction with known endoscopic or laparoscopic cameras or optical equipment to observe/confirm the procedure.
• the present device is extremely useful in any endoscopic, laparoscopic, thorascopic or similar procedure where directional angular applications of components, e.g., fibrin sealant components, is required. It can be used in nearly all "minimally" invasive procedures and provides a great benefit by providing a comfort level to the surgeon, regarding fluid and air leakage, which is comparable to that realized in standard open surgical procedures.
• components e.g., fibrin sealant components
