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™.

Pu Jie Jie™

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.

Pu Jie Jie™ Medical Radiation Protective Shield

A green shield that protects doctors from intraoperative X ray irradiation during interventional ultrasonographic procedures in the catheterization room.



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.

Magpie™ Balloon Dilatation Catheter

A non-compliant balloon dilatation catheter suitable for native valve dilation of cardio-aortic aortic valves.



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.

DragonPath™ Transseptal Puncture System

For creating access to the left heart via transfemoral vein transseptal puncture into the left atrium.



Consisting of core wire and wire coil.

The product surface is coated with a layer of polytetrafluoroethylene (Teflon).

The core wire and wire coil are made of 304 stainless steel.

Special double curve pre-shaped tip (“双弯预塑形头端”)for easy and stable positioning in the left ventricle.

Stable morphology maintenance capacity for minimizing heart tissue injury.

Two curve sizes available for hearts of different sizes.

Two guidewire hardness values available for use with medical device products of different hardness.

Appropriate supporting performance and compliance by virtue of agreeable body hardness suitable for transarc, release, and stabilization.

Firework™ Stiff Guidewires

Suitable for cardiovascular (coronary exclusive) interventional diagnostics and treatment procedures, especially interventional procedures for delivery devices into blood vessels, and positioning/establishing access to blood vessels.
