Biological Suture Core with Composite Cover for Healing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical sutures made from synthetic materials lack the biocompatibility and enhanced wound healing properties that biological materials like collagen can provide, particularly in promoting tissue regeneration and healing.
Innovation Solution
Development of surgical sutures comprising a core made substantially of biopolymers or proteins, such as collagen, which can be optionally covered with a braided layer and impregnated with biological components like blood, growth factors, or antibiotics to enhance healing, and coated for improved handling and retention at the surgical site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If synthetic materials are used for surgical sutures, then strength and durability are improved, but biocompatibility and wound healing properties deteriorate
Solution Approach 1:
The patent applies composite materials by combining synthetic suture material with biological materials (collagen, blood, growth factors) to create a hybrid structure that provides both mechanical strength from the synthetic component and biocompatibility/healing properties from the biological component. The biological material is applied to the synthetic suture through impregnation, coating, or binding, creating a composite structure that resolves the contradiction between strength and biocompatibility.
2Reliability
If biological materials like collagen are used for surgical sutures, then biocompatibility and wound healing properties are improved, but strength and durability deteriorate
Solution Approach 1:
The patent uses composite materials to combine the biocompatibility of biological materials with the strength of synthetic materials. The synthetic suture material provides the mechanical framework and strength, while the biological materials (collagen, blood, growth factors) are applied as coatings or impregnations to provide biocompatibility and healing properties without compromising the underlying structural integrity.
3Reliability
If biological material is applied to synthetic suture, then healing properties are improved, but manufacturing complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-applying biological materials to the synthetic suture during the manufacturing process rather than requiring post-manufacturing application. The biological materials are impregnated, coated, or bound to the suture material in controlled manufacturing steps, ensuring uniform distribution and proper integration before the suture is used surgically.
Solution Approach 2:
The composite material approach allows for integrated manufacturing where biological and synthetic materials are combined in a single production process. The biological materials are incorporated into the synthetic suture structure through impregnation, coating, or binding techniques that can be performed during manufacturing, creating a ready-to-use composite suture product.

AI summary
A surgical suture having a core made substantially of biological material (such as biopolymers or proteins, for example) and a cover surrounding the core. The section comprising the biological material may be provided adjacent at least a section of suture not comprising biological material. The section comprising the biological material may be provided in the form of strands or a matrix or a spongy material, which may be additionally treated with biological components such as blood, blood fractions or components, platelet-rich plasma, autologous conditioned plasma, bone marrow aspirate, growth factors, antiseptics, and antibiotics, among others.
