Solution Overview

Problem

Current medical procedures for implanting devices in the pelvic region require time and skill due to the complexity of tying multiple knots to secure implants, which can be cumbersome and inefficient.

Innovation Solution

A medical device comprising an elongate member, a suture, and a needle, where the suture is wrapped around the elongate member and the needle is used to pass through tissue to form knots, facilitating the secure attachment of implants within the body.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional manual knot-tying methods are used to secure implants, then reliable attachment is achieved, but procedural time and operational complexity increase significantly

Engineering Contradiction:

Improveimplant attachment reliabilityVSAvoidprocedural time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The suture is pre-wrapped around the elongate member a specific number of times (e.g., 4-8 times) before insertion, creating pre-formed loops that will become knots. This preliminary configuration eliminates the need to tie multiple knots manually during the procedure, significantly reducing procedural time while maintaining secure attachment

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The elongate member serves as an intermediary tool that facilitates knot formation. By having the suture pre-wrapped around it, the elongate member enables automatic knot creation when passed through tissue, converting a complex manual task into a simple insertion and pulling motion

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If multiple sutures and knots are used to secure implants, then secure attachment is achieved, but device complexity and skill requirements increase

Engineering Contradiction:

Improveimplant attachment reliabilityVSAvoidknot-tying complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The invention combines the elongate member, pre-wrapped suture, and needle into a single integrated device. This merging of components simplifies the overall system by eliminating the need for separate knot-tying instruments and manual manipulation of multiple sutures, reducing both device complexity and the skill level required to operate it

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If traditional knot-tying procedures are performed, then implant security is achieved, but ease of operation deteriorates due to skill and time requirements

Engineering Contradiction:

Improveimplant securityVSAvoidknot-tying ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The device performs the knot-tying function automatically through its design. When the elongate member with the pre-wrapped suture is inserted and pulled through tissue, the pre-formed loops automatically create secure knots without requiring the operator to perform manual tying operations, making the procedure easier to perform while maintaining implant security

Inventive Principle:

Principle #25Self-service

AI summary

According to an aspect, a device includes an elongate member, a suture, and a needle. The elongate member has a first end portion and a second end portion. The elongate member defines a lumen and a slot. The lumen extends from the first end portion to the second end portion. The slot extends from the first end portion to the second end portion. A portion of the suture is wrapped around the elongate member. The needle is coupled to the suture.
