Streamlined Delivery for Curable Materials in Critical Applications

Introduction

Delivering curable materials in precise amounts and at the right moment is essential in numerous fields, from medical procedures to industrial applications. Whether it’s delivering bone cement in orthopedic surgery or applying adhesives in a manufacturing setting, accuracy and efficiency can be the difference between success and costly errors. This curable material delivery device offers an advanced solution for professionals needing precise control over material flow in time-sensitive situations.

The Challenge

In both medical and industrial settings, delivering curable materials like bone cement, dental composites, or construction adhesives can be fraught with challenges. Improper mixing, inconsistent flow, or timing issues can lead to compromised outcomes. For example, in surgery, improper delivery of bone cement could result in joint instability or increased patient recovery time. Similarly, in construction or dental applications, inaccurate application of adhesives can lead to structural weakness or product failure.

The demand for a device that simplifies material handling while ensuring accuracy and consistency is growing. The complexity of current tools often results in delays or errors that negatively affect performance, adding cost and risk to the procedure or process.

Please see terms and conditions
An apparatus and method for introducing material into an injection site of a patient is disclosed. The device includes a cannula and a carrier. The cannula is inserted into an injection site of a patient. The carrier is connected to an injector containing a volume of material. Material may be pre-loaded into the carrier so that the material is delivered to a distal end of the carrier from the injector and the carrier is thus pre-loaded with material. A portion of the distal end of the pre-loaded carrier is inserted into the cannula and material is delivered to an injection site.

1. An apparatus for introducing material into an injection site of a patient comprising:

a cannula defining a lumen;

a carrier for delivering material from an injector to an injection site, the carrier defining a lumen and the carrier comprising

a supply section operable to receive curable material, and an inner section having an axis and defining a tip section operable to direct material in a direction that is off-axis relative to the axis of the inner section, wherein the carrier is releasably attachable with the cannula, and at least a portion of the inner section is located within the lumen of the cannula, wherein said portion is at least 50% the length of the cannula.
2. The apparatus of claim 1 wherein the tip section defines at least one orifice for delivering material.
3. The apparatus of claim 1 wherein the tip section defines at least two orifices for delivering material wherein the orifices at least two of the orifices are of different size.
4. The apparatus of claim 1 wherein the cannula is connected with a handle having a connector operable for attaching the carrier.
5. The apparatus of claim 1 wherein the carrier further comprises a connector operable for attaching to the cannula.
6. The apparatus of claim 1 wherein the supply section is a tube having a first end and a second end and the inner section is a tube having a first end and a second end.
7. The apparatus of claim 6 wherein the carrier further comprises a connector for connecting an end of the supply section with an end of the inner section wherein the connector defines a chamber between an end of the supply section and an end of the inner section.
8. The apparatus of claim 7 wherein the supply section, chamber and inner section form a lumen section having walls defining a substantially smooth transition from the supply section to the inner section.
9. The apparatus of claim 8 wherein the supply section and inner section have inner diameters that are different and an inner wall of the chamber is tapered to form a transition from a first diameter to a second diameter.
10. The apparatus of claim 9 wherein a first end the supply section connects with an injector containing a volume of material.
11. The apparatus of claim 6 wherein the supply section and inner section are made of non-compliant materials.
