Solution Overview

Problem

Current bone graft delivery systems often require invasive surgical procedures and lack efficient methods for minimally invasive delivery and decortication of bone graft material.

Innovation Solution

A bone graft delivery system comprising an elongated tube with a handle and a distal tip featuring one or more openings for delivering bone graft material and a rasping surface for decortication, allowing for minimally invasive delivery and bone preparation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If open surgery implantation is used to deliver bone graft material, then the bone graft can be placed into the target location, but the surgical invasiveness increases and recovery time extends

Engineering Contradiction:

Improvebone graft delivery reliabilityVSAvoidsurgical invasiveness

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the traditional mechanical open surgery approach with a minimally invasive percutaneous needle-based delivery system. The bone graft material is delivered through a needle catheter directly into the target bone location, eliminating the need for large surgical incisions and extensive soft tissue dissection while maintaining effective graft placement

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The delivery system utilizes a thin-walled needle catheter that can be inserted through small percutaneous access points. The flexible yet structurally sufficient catheter wall allows minimally invasive insertion while maintaining the integrity of the bone graft material during delivery

Inventive Principle:

Principle #30Flexible shells and thin films

2Reliability

If decortication is performed to expose cancellous bone for better graft integration, then bone integration accelerates, but the procedural complexity and time increase

Engineering Contradiction:

Improvebone graft integrationVSAvoidprocedural complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the decortication function and bone graft delivery function into a single integrated needle catheter device. The catheter incorporates both a decortication tip for removing cortical bone and openings for graft material delivery, allowing both functions to be performed through one minimally invasive insertion without requiring separate surgical steps

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The needle catheter is designed as a multi-functional device that can perform decortication, deliver bone graft material, and potentially provide structural support. This universal device eliminates the need for multiple separate instruments and surgical procedures, reducing overall procedural complexity while achieving the same therapeutic goals

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A bone graft delivery system can include an elongate tube and a handle having a trigger and a ratcheting mechanism. The trigger is actuated to deliver bone graft material through the tube. The bone graft delivery system can further include a distal tip at a distal end of the tube. The tip has one or more openings to deliver the bone graft material to a desired location and includes a surface suitable to act as a rasp for decorticating bone. A method for delivering bone graft material to a desired surgical location includes providing a bone graft delivery device, positioning the device adjacent the surgical location, decorticating bone, and delivering bone graft material to the surgical location.
