The Venapax Difference


A re-imagined approach to EVH

We believe that our industry functions best when there is continuous innovation fueled by constant communication with you, the clinical experts who make great outcomes a reality. Our focus is to advance the field of EVH by pioneering a system born and refined by feedback received in close partnership with the harvester community and hospital facilities.


Integration that Facilitates Action

Imagine no device exchanges and just a single unit to control. Venapax’s innovative design transforms the EVH process with streamlined operation and excellent conduit quality.

The reality? A unitary device that lets you dissect, cauterize and ligate branches on the fly.

All-in-one design, all for your needs

  • Dissect, cauterize, and cut as you go —eliminating the need to insert and control a second device or exchange a device for additional dissection.
  • Cauterize and cut even the smallest branch vessels during dissection, which may reduce branch avulsions. 
  • Intelligent electrode high-density current pathway minimizes smoke generation to enhance visibility during the procedure.
  • Hemostatic system allows spot cauterization of any bleeding so the tunnel stays dry during dissection.


A Minimal-touch Approach

Thermal vessel injuries and vessel manipulation that occur during typical endoscopic harvests have been shown to greatly reduce graft patency. Venapax was designed to approach a ’no touch’ technique focused on minimizing vessel manipulation to optimize graft quality. With less vessel manipulation and a graft conduit with decreased spasm, increased distensibility with enhanced flow rates is possible. The design of Venapax has the potential to improve graft quality in a number of ways.

High-strength seal and low thermal spread with our High-Density Current Pathway design

  • Venapax features an intelligent design that tailors the energy delivery to each specific branch, which results in a high-strength seal with low thermal spread and low char.
  • The electrode geometry and material make efficient use of the energy available by focusing it on a very small area to deliver energy where it is needed most.
  • The system has real-time feedback to adjust the level of energy delivered to the branch. Tissue impedance is measured real-time to constantly adjust the flow of energy automatically, delivering a treatment that’s tailored specifically to each branch rather than a one-size-fits-all energy delivery approach.

No vessel manipulation through a decoupled electrode configuration

  • The bipolar electrodes are decoupled, which means they do not require an additional appendage to engage the target vessel to apply tension to the branch, potentially reducing the risk of damage to the conduit wall and intima.
  • The decoupled electrodes allow for free control of the device in space, which results in long branch lengths and possible preservation of more vaso vasorum and adventitia.
  • It is not necessary to contact or manipulate the target vessel in order to take a branch.

Smooth Is Better

  • The smooth conical tip remains in place throughout the entire procedure, preventing the target vessel from being exposed to a rough circumferential edge during branch taking. This can reduce the potential for damage to the conduit wall and intima.
  • A soft, pliable trocar is utilized to reduce the potential for vessel damage at the incision site.
  • Avoiding rigid structures near the incision site may reduce the potential for vessel stasis during the procedure.
  • It can also be trimmed to a desired length if needed.


Outcomes that Make Sense

In the cardiac OR, patient outcomes are everything. The ability to achieve the best possible results and outcomes in the most efficient manner is paramount. Saphena understands your needs, and Venapax is designed to address them.

Helping reduce procedure time

  • Cauterizing and cutting branches as you dissect may improve management of even the smallest branches.

Shortened learning curve

  • Venapax’s intuitive design coupled with our procedural training process allows the experienced harvester to quickly adopt the device into the workflow.

Evolving EVH to enhance value

  • Continued commitment to design and process improvements translates to a drastic reduction to the overall expense of the entire EVH disposable cost.
  • Comprehensive procedural training programs help users get up to speed quickly so users can experience the Venapax advantage sooner.

"I have been very happy with the quality of the veins that our first assistants have been able to harvest with Saphena’s device. It provides us with a quality vein comparable to what we used to see with open vein harvesting.”

– Geoffrey R Cousins, MD, Cardiac Surgeon at St. Mary’s Medical Center in Huntington, WV.

“We have been able to compare Venapax to the other devices and have found less trauma to the vein during harvesting. I have seen less bleeding during harvesting as evidenced by less bruising or hematoma formation post-operatively. I am very happy with this system and prefer it for all of my patients requiring EVH."

– Nepal C Chowdhury, MD, Cardiac Surgeon St. Mary’s Medical Center, Huntington, WV

"The more cases I do the better the vein graft looks. I never have to repair anything, just tie branches."

– Eric Ping, ACNP

“The quality of the vein is more pristine with fewer avulsions and fewer thermal burns as compared to the other systems we have trialed.”

– Dr. Scott Schubach, Chairman of Cardiac Surgery, NYU Winthrop Hospital

"Since learning to use the Saphena Venapax system, my vein quality is consistently better than with any other device I have used in the last 20 years. "

– Matt Petrides PA, Manager, Cardiothoracic Surgery

This is a true minimal-touch instrument. The integrated design allows for simultaneous dissection and ligation of the branches as you move down the tunnel.

– Michael Sullivan PA-C

"The ability to dissect with minimal distortion of the vein while providing long branches decreases the risk of unseen intimal damage. I have observed excellent vein quality and no leg wound issues with the use of Venapax.”

– Dr. Steven A Leyland

"Venapax is producing the highest quality conduit I’ve seen in my years of cardiothoracic surgery. It reduces venous compression and traction, resulting in less endothelial damage, therefore enhancing graft patency. "

– Aaron Amburgey PA-C

“Since we first began using the simplified method of vein harvesting with Venapax, I have noticed a significant decrease in the learning curve of our new and inexperienced vein harvesters. "

– Dr. Scott Schubach, Chairman of Cardiac Surgery, NYU Winthrop Hospital
