Devascularizing Material for Minimally Invasive Uterine Tissue Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for uterine abnormalities such as endometriosis, polyps, and fibroids often involve painful procedures, hormone therapy with adverse side effects, or surgical removal of the uterus, which can cause trauma and require hospital admission, while lacking a minimally invasive solution for treating the target tissue effectively.
Innovation Solution
The use of a devascularizing material applied topically or injected directly into the target tissue to disrupt blood supply and reduce biological activity, allowing for selective treatment of uterine abnormalities without surgical removal, using a surgical device with a treatment end that includes an injection needle or application shaft to administer the material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surgical removal of the uterus or target tissue is performed, then the abnormality is effectively treated, but physical and psychological trauma is caused and hospital admission is required
Solution Approach 1:
The invention extracts and removes only the abnormal tissue (polyp, fibroid, or endometriosis) while preserving the healthy uterus and surrounding tissues. The surgical device selectively targets and removes the pathological growth through the cervix without requiring removal of the entire uterus, thereby maintaining treatment effectiveness while minimizing physical trauma and psychological impact.
Solution Approach 2:
The surgical device applies local quality by concentrating the treatment effect precisely at the abnormal tissue site. The device delivers energy or mechanical action localized to the polyp, fibroid, or endometriosis, achieving effective treatment of the target while leaving the surrounding healthy uterine tissue intact, thus reducing overall trauma to the patient.
2Object-affected harmful factors
If hormone therapy is used, then symptomatic treatment is provided, but adverse side effects occur and the underlying cause is not treated
Solution Approach 1:
The invention converts the harmful approach of hormone therapy into a beneficial mechanical or energy-based treatment. Instead of using hormones that cause side effects, the surgical device directly addresses the root cause (abnormal tissue) through localized mechanical removal or energy ablation, eliminating the source of symptoms without introducing adverse hormonal side effects.
3Reliability
If UAE is performed, then fibroid treatment is achieved, but particles may migrate to wrong locations and the procedure requires a specialist doctor
Solution Approach 1:
The surgical device acts as an intermediary tool that provides precise mechanical or energy-based treatment to fibroids and other abnormalities. Unlike UAE particles that rely on circulatory transport, the surgical device directly delivers treatment to the target tissue through controlled mechanical action or localized energy, ensuring precise placement and eliminating the risk of particle migration to wrong locations.
4Reliability
If polypectomy is performed, then the polyp is removed, but surgical tools and hysteroscope insertion are required
Solution Approach 1:
The surgical device is designed with multi-functionality to treat various uterine abnormalities including polyps, fibroids, and endometriosis through a single integrated system. The device can adapt its treatment mechanism (mechanical removal, energy ablation, or a combination) based on the type of abnormality, eliminating the need for different specialized tools and hysteroscopes required in traditional polypectomy procedures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enables effective treatment of uterine abnormalities with minimal equipment and risk, as a minimally invasive outpatient procedure, reducing the need for symptomatic treatments or hormone therapy and avoiding the removal of the uterus, thereby minimizing trauma and anxiety for patients.
Implementation Method 1
administering a devascularizing material to the target tissue, wherein the devascularizing material is able to devascularize the target tissue
Data Source
AI summary
A method for treating target tissue comprises introducing a portion of a surgical device into a patient, the surgical device having a treatment end, positioning the treatment end of the surgical device adjacent to the target tissue, and administering a devascularizing material to the target tissue. The devascularizing material, after a time period, is able to devascularize the target tissue. A surgical device comprises a shaft extending between proximal and distal portions, a treatment end located at the distal portion, where the treatment end administers the devascularizating material to a target tissue.
