Add-on Plastic Tips for Cryogen Administration in Difficult-to-access Areas

Area of Science:

• Medical Devices
• Surgical Techniques
• Cryotherapy

Background:

• Targeted cryotherapy is effective for lesion treatment.
• Accessing lesions in difficult locations poses a significant challenge for current cryotherapy methods.
• Improved delivery systems are needed for enhanced therapeutic outcomes.

Purpose of the Study:

• To develop and evaluate novel add-on tips for targeted cryotherapy delivery.
• To address the challenge of treating lesions in difficult-to-access anatomical sites.
• To provide a cost-effective and accessible solution for cryotherapy application.

Main Methods:

• Custom add-on tips were fabricated using readily available materials: disposable micropipettes, needle caps, and syringe barrels.
• The add-on tips were designed for secure attachment to standard cryotherapy devices.
• The functionality and applicability of the fabricated tips were assessed in simulated difficult-to-access scenarios.

Main Results:

• The fabricated add-on tips demonstrated successful adaptation to standard cryotherapy applicators.
• The novel tips facilitated targeted application of cryotherapy in simulated challenging locations.
• The materials used are inexpensive and widely available, suggesting a low-cost solution.

Conclusions:

• Add-on tips fashioned from disposable micropipettes, needle caps, and syringe barrels offer a practical solution for targeted cryotherapy in difficult locations.
• This innovation can potentially improve the efficacy and accessibility of cryotherapy for a wider range of clinical scenarios.
• Further clinical validation is warranted to confirm the safety and effectiveness of these add-on tips.
