Soft-Flow Arterial Cannulae
Cardiac Surgery
Overview
Designed to be gentle on the aorta and easy to insert, Soft-Flow®* arterial cannulae help you proceed with confidence during cardiac surgery procedures.
As the first diffusion tip arterial cannulae on the market, the Soft-Flow was the cannula of choice for many cardiac surgeons. Working with MC3 Cardiopulmonary, we’ve made it possible to bring Soft-Flow arterial cannulae back to the market. Medtronic is the exclusive distributor and MC3 Cardiopulmonary is the manufacturer. Orders may be placed through your local Medtronic products representative.
Indications
Soft-Flow arterial cannulae are indicated for use in the perfusion of the ascending aorta during cardiopulmonary bypass (CPB) surgery. They are single use products, and are indicated for up to 6 hours of use.
Compare Velocity Performance
Soft-Flow®* arterial angled-tip cannula showed a lower exit velocity than the Medtronic Select Series™ arterial angled open-tip cannula in an independent 3C-PIV bench test.**
Reduce Jetting Effect
Advanced flow visualization analysis demonstrates Soft-Flow arterial cannula provides a divided blood flow pattern which lessens the jetting effect observed with open-tip aortic cannulae.** The closed diffusion tip is designed to help reduce the risk of dislodging plaque from the aortic wall.1
**MC3, Inc. data on file. Testing was conducted in 3rd-party laboratory setting with aortic arch models and CPB circuit that utilized a Three-Component Particle Image Velocimetry (3C-PIV) technology to capture flow data. 3D velocity data is visualized in one 2D plane per image. The images capture the peak velocity for each cannula. Flow still occurs in unshaded vessel areas. These tests may not be indicative of clinical performance.

Product Details
All Soft-Flow cannulae feature kink-resistant wire-wound bodies and a 3/8” vented or non-vented connector.
Choose:
- Extended body with suture ring
- Straight tip with suture bulb
- Angled tip with suture bulb or suture flange
Soft-Flow Extended Arterial Cannulae
The extended-length, kink-resistant, wire-wound body allows use across various patient anatomies. An orientation line, depth markings, and suture ring help you position the cannula.
Tip of Soft-Flow extended arterial cannula
The closed tip has an inner cone that directs flow through side vents. This results in a diffuse, lower velocity flow.
Soft-Flow straight tip arterial cannula
A smooth, tapered, reverse-angle tip is designed to facilitate insertion and placement.
Soft-Flow angled tip arterial cannula with suture bulb
A smooth, tapered, reverse-angle tip is designed to facilitate insertion and placement.
Soft-Flow angled tip arterial cannula with suture flange
A smooth, tapered, reverse-angle tip is designed to facilitate insertion and placement.
Flow Performance
Right Flow When You Need It
Soft-Flow®* cannula flow charts are provided for your comparison. Each flow curve represents in vitro laboratory data obtained using water at room temperature. The actual pressure drops encountered in a clinical situation may vary from those shown, depending on the blood viscosity and temperature.
