Device for Applying an Active Agent to or into Organic Tissue and Method

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent concerns a device and method for repeatedly penetrating organic tissue, such as human or animal skin, in a more gentle and less painful way. The device uses at least two application tools (such as needles or blades), which are moved relative to each other so that their forces oppose each other, stretching the tissue and facilitating penetration. This mechanism can be adapted for both manual and machine-driven operation and is suitable for delivering various substances—including drugs, pigments, or cosmetic agents—onto or into the tissue.

Use CasesContent extracted from patent full text and abstract with AI.

• Tattooing and permanent makeup with reduced pain and skin trauma.
• Medical drug delivery (e.g., vaccines, insulin, or other medications) through the skin in a controlled, minimally traumatic manner.
• Cosmetic procedures such as anti-aging treatments, hair follicle implantation, or microneedling.
• Diagnostic skin tests that require repeated or precise penetration (such as allergy tests).
• Transdermal gene, cell, protein, or nanoparticle delivery for regenerative medicine or therapeutic purposes.

BenefitsContent extracted from patent full text and abstract with AI.

• Reduces pain and trauma compared to traditional penetration methods, making procedures more comfortable for patients.
• Provides precise and repeatable penetration depth and force, improving safety and treatment outcomes.
• Supports both manual and machine operation, allowing flexible adaptation to different clinical, cosmetic, or personal use scenarios.
• Can deliver a wide variety of substances (liquids, particulates, biological agents) efficiently into tissue.
• Modular construction allows for easy replacement or disposal of single-use components, enhancing hygiene and reducing contamination risks.
• Tissue-stretching mechanism prevents the skin from excessively shifting, leading to cleaner and more accurate substance delivery.

Patent Abstract

The device has a penetration device comprising an arrangement of application tools (1, 2), which are coupled to an operating mechanism. The application tools are displaceable relative to each other between an initial position and a penetration position by the operating mechanism. An effect direction of application force provided by one application tool is counter to an effect direction of the application force provided by another application tool during the relative movement of the application tools. An independent claim is also included for a method for applying an active ingredient on or into an organic tissue.
