Cardiovascular Systems Stock (CSII): Why The Price Went Up Today

By Amit Chowdhry ● Jan 14, 2022
  • The stock price of Cardiovascular Systems Inc (NASDAQ: CSII) increased by 6.14% today. This is why it happened.

The stock price of Cardiovascular Systems Inc (NASDAQ: CSII) – a medical device company developing and commercializing innovative interventional treatment systems for patients with peripheral and coronary artery disease – increased by over 3% during intraday trading. Investors are responding positively to Cardiovascular Systems announcing it has made significant progress towards the commercialization of intravascular lithotripsy (IVL) systems for the treatment of calcific coronary and peripheral artery disease.

Lithotripsy is known as a medical procedure that uses non-invasive high-pressure waves to fracture and disrupt pathologic solid masses. And lithotripsy has been used successfully for many years in the treatment of kidney and gall stones and more recently has found application in the treatment of calcified coronary and peripheral arteries.

The feasibility testing of a proprietary console and associated IVL balloon catheters is complete. The CSI IVL systems are designed to improve upon the limitations of incumbent technology, allowing physicians to cross and treat more challenging atherosclerotic lesions. And the commercialization of the IVL systems will be highly complementary to CSI’s broader portfolio of advanced vessel preparation technologies.

In coronary, CSI’s current product offering — which is focused on the treatment of severely calcified coronary arteries using orbital atherectomy — targets 12% of percutaneous coronary interventions (PCI). The addition of a coronary IVL system will enable CSI to offer products that effectively treat a broader range of calcific coronary lesions, tripling CSI’s total addressable market (U.S.) to $1.3 billion. And the enrollment of patients in an investigational device exemption study for the CSI coronary IVL system is currently targeted for calendar 2023.

CSI’s peripheral orbital atherectomy devices are primarily used by physicians to treat long, diffuse calcified arteries below the knee. Introducing a peripheral IVL system to the CSI offering will expand its treatable patient population across an even broader spectrum of calcified arteries above and below the knee, thus increasing CSI’s addressable market (U.S.) by over 50% to nearly $1 billion. And CSI plans to begin first in-human experience for the peripheral IVL system in calendar 2023.


“The development of an IVL system for the treatment of coronary and peripheral artery disease will uniquely position CSI to provide the right device, for the right lesion, for all physicians. We believe the successful execution of this program will greatly expand patient access to care and CSI’s overall market position in complex coronary and peripheral disease.”
