Solutions

Safe and effective clamping for more intuitive and convenient operation, achieving a therapeutic effect with greater precision for a wide range of different patients.

Central filler with an ingenious, adjustable clamping angle (within 45°) designed for reducing residual central regurgitation and concurrent flexible adjusting of the post-operative pressure differential.

Four clip sizes, customizable to fit mitral regurgitation patients with a variety of pathological changes and anatomic structures.

Improved procedural success rate and operative efficiency in complicated cases by virtue of independent grasping function capable of grasping one-side in difficult situations.

Visualized quantitative operating system, calibration knob, and three-segment catheter body design for more accurate and simple operation.

Fully independent intellectual property rights of DragonFly™. By September 2023, a total of more than 150 Chinese and foreign patents had been applied for in the areas of fundamental principles, core solutions, and key innovation of products, including 95 Chinese and foreign patents of inventions and 28 PCT applications of which 30 patents were granted.

Granted access to the "green channel" for innovative products by the NMPA in accordance with the Special Review Procedure for Innovative Medical Devices in March 2021.Won first prize for vascular medical devices and second prize for high-value consumables in the 6th session of the China Medical Devices Design & Entrepreneurship Competition in September 2023.Three papers related to Valgen products were published in JACC: ASIA and other renowned English journals.

The "Dragonfly™ Transcatheter Mitral Valve Repair System R&D" project received support from the Diagnostic and Therapeutic Equipment and Biomedical Material Special Program and the National Key Research and Development Program for the "14th Five-Year Plan". Granted marketing authorization by the National Medical Products Administration (NMPA) in November 2023; it is the first Chinese transfemoral transcatheter edge-to-edge mitral valve repair system product ever approved.

Lead equivalent: Meeting the requirements in the applicable National Standard.

Unique operation window: Doctor's exposure to radioactive rays minimized.

Ultrasonic probe hanger: For hanging the control handle of the ultrasonic probe to facilitate control of the ultrasonic probe.

Arm support: Used to prevent operator fatigue by supporting the operator's arm and facilitating operation.

Suspension support: For carrying the display that synchronously displays DSA images in split-screen mode to improve collaboration of the team.

Hub box: For carrying the wireless signal source of the display for a more compact appearance.

High rated burst pressure: Non-compliance balloon body that focuses the dilating force to achieve uniform and consistent dilation of stenosis.

Rapid filling and relief of pressure: Larger fill cavity area, shorter low perfusion and fast pacemaker duration for cardiac function protection.

Eight-pedal flap: More regular initial morphology, smaller external diameter, and more stable back embrace morphology for reuse after remodeling.

Reinforced inner catheter: Inner catheter with additional braided mesh, which reinforces the catheter body and enables the safe application of the catheter in patients with a sharp angle arc and horizocardia.

Puncture sheath: Increased hardness, greater supporting force; Better anti-bending performance, sheathing canal less susceptible to deformation; Greater torsional strength, better axial orientation; Smaller frictional force, better vascular passability;

Puncture needle: For its stronger puncture strength, appropriately sharp point design, and unique post-treatment process for removing sharp edges and burrs, the needle enables comfortable control when puncturing and prevents sliding and mispuncturing.
