Surgical Stapler: ES Vascular Raises $3M

ES Vascular has developed highly-advanced surgical staplers for endovascular surgery, open aortic surgery and critical limb ischemia (CLI). Private investors have now invested $3 million in hopes that the company’s Open Aortic Stapler will soon receive the CE mark which will allow it to begin marketing in Europe. The money should also help the company complete clinical studies on its other staplers.

Founded in Israel in 2003 by Prof. Edward G. Shifrin, a vascular surgery expert, ES Vascular’s staplers “form a continuous ringed line of staples with no gaps between adjoining staples to eliminate leakage and bleeding.” The company claims that these staplers will drastically reduce complications arising from current surgical procedures.

According to its website, ES Vascular products will address a large and growing market:

  • The Company’s immediate addressable market for the Aortic Staplers includes over 120,000 patients undergoing open AAA repairs annually worldwide.
  • The US endovascular AAA device market reached close to $500 million in value in the year 2004.
  • In the US and EU 1.9 million surgical interventions are performed for patients suffering from CLI.

ES Vascular claims its staplers offer the following advantages:

  • Its Open Stapler creates a quick, uniform, one-shot sutureless anastomosis and may eliminate up to 90% of suturing time, reduce clamping and operative times as well as re-clamping cycles and bleeding.
  • Once the stapler is in place the staples are deployed in one shot, firmly fixating the stent graft to the aortic wall and possibly preventing one of the most common problems of current EVAR devices.
  • CLI Endostapler will facilitate a minimally invasive procedure that can replace an open femoral-popliteal bypass (FPB) operation. Eliminating open end-to-side anastomoses, this device will potentially improve patency rates and reduce hospitalization to a one night hospital stay.

  1. The ES vascular device seems to compete with the Aptus medical device, which seems like a sophisticated yet simple procedure for excluding AAA. According to endovascular today .The Aptus Endovascular AAA Repair System (Aptus Endosystems, Inc., Sunnyvale, CA) divides the endovascular AAA repair procedure into two steps: (1) exclude the aneurysm with an endograft designed to provide radial support while maintaining longitudinal compliance and (2) secure the endograft to the vessel wall with an endovascular stapling system that provides transmural aortic fixation with a high pull-out force proportional to the number of EndoStaples (Aptus) deployed.
    The Aptus modular endograft is designed specifically for use with the Aptus Endovascular Stapling System, which in turn is designed to provide secure fixation of the proximal edge of the endograft to the infrarenal aortic wall.
    The modular endograft is designed to accommodate changes in aneurysm and/or aorta morphology without compromising graft integrity, graft patency, or arterial attachment and sealing. In addition, this two-step approach to endovascular AAA repair allows for a significant reduction in the profile and increased flexibility of the delivery systems (endograft and EndoStaples). The modular endograft and the EndoStaple Applier are delivered through a 14-F sheath (16-F outer diameter). These attributes may allow a broader range of patients to be safely treated with an endovascular procedure.
    The Aptus Endovascular Repair System provides active fixation via an endovascular stapling system that allows placement of EndoStaples along the proximal edge of the main body endograft. The EndoStaple is a 4-mm helical staple manufactured from medical-grade wire designed to engage the full thickness of the aortic wall in an active fashion.
