Thank you, Glenn, and thanks to everyone for joining the call this morning.
Without a doubt, the most significant development since our last quarterly update and one of the most significant milestones in InspireMD's history is our completion of a transformational financing through a private placement of up to $113 million. The financing was led by Marshall Wace, with participation by OrbiMed, Soleus, Nantahala, Rosalind and Velan Capital. These are amongst the most highly regarded medical technology institutional investors.
It's also worth noting that a certain number of our Board members have also elected to participate in the offering. We are both inspired and humbled by this vote of confidence, which fuels our company's growth and enables our strategic goal to change the therapeutic standard of care in the carotid disease market.
Pursuant to the engagement, we received an initial $42.2 million in gross upfront capital, with an additional 4 tranches of $17.9 million each, tied to milestones totaling $113.6 million fully exercised.
The warrants are tied to the following milestones: First, the readout of top line 12-month data from our ongoing FDA C-Guardians IDE clinical trial; second, receipt of premarket approval, PMA from the FDA for the CGuard Prime Carotid Stent System; third, the announcement of receipt of FDA approval for the SwitchGuard trans carotid system and CGuard Prime 80 cm; and fourth, the first 5 quarters of commercial sales in the U.S. market.
The funds are intended to further catalyze our milestone execution, including approval in launching our new products in the U.S. and in our current served countries, including the CE Mark territories, advancing our tandem lesion indication for CGuard and establishing a U.S. base of business operations and commercial architecture.
With our balance sheet significantly strengthened, we can accelerate our plan to drive value inflection by way of advancing CGuard EPS through their U.S. regulatory pathway, while commencing the build-out of a world-class commercial infrastructure, deeply committed to making CGuard broadly available to the many patients with carotid artery disease who stand to benefit from this novel advancement and sensing technology.
The mission of our business remains unchanged, which is to focus on implant performance and positive patient outcomes. As a reminder of the superiority of our unmatched data from 9 rigorously designed peer-reviewed clinical studies that have enrolled approximately 1,850 patients, CGuard EPS demonstrated superior short- and long-term clinical outcomes, measured by the lowest complication range of death, stroke and myocardial infarction as compared to both competing first-generation stent systems as well as surgical endarterectomy.
Turning now to the quarter. We generated total revenue of $1.2 million, representing growth of 4.7% over the first quarter of 2022. This was driven by a 6.7% increase in sales of CGuard EPS in our 30 served markets.
As we shared in our last quarterly reporting, our temporary restriction of sales due to the loss of MDD certification in November 2022, created a gap in sales and shipments, which was resolved in the second half of the first quarter. It is significant to note that we were able to generate year-over-year revenue growth despite this restriction. But more importantly, we're able to successfully maintain sufficient inventory in our channels to avoid loss of procedural volume and access for patients for our CGuard stent for best patient care.
It is a testament to the tire report and focus of the entire InspireMD team that we were able to maintain availability in our markets and address patient needs, despite with temporary interruption of [ CE Mark ].
Recall that in November 12 of last year, our CE Mark certification temporary last as European regulators transition from the existing MDD directive regulatory framework, which governs the marketing approval and sale of medical devices in the EU to the medical device regulation framework or MDR. This transition resulted in a well-documented and significant delays by the European regulatory bodies in processing of application and audit under the new MDR certification.
The MDR deadline for transition to updated certification has taken more than 3 years with multiple revisions, delays and requirement changes, putting the entire medical device industry serving the EU markets at risk. This complexity, combined with the constantly changing requirements and deadlines, has made this a challenging undertaking for all medical device companies that fall under the MDD purview.
In anticipation, we proactively worked with our distributor partners and provide as much available inventory as possible to avoid shortages, while continuing to complete the MDR process to reestablish sales, which we have successfully done and are now able to resume normal cadence in our sales efforts.
As a reminder, we enjoy greater than 25% market share in over half of our served CE Mark territories, with some exceeding 80%. We believe our continued efforts on the ground, together with the launch of 2 new stent delivery platforms, will enable share growth and accelerate the conversion of surgeries to endovascular standard of care with the CGuard stent system.
Our mission remains unchanged, to convert the last surgery first segment of vascular medicine to an endovascular first-line standard with a best-in-class implant with CGuard EPS. With a full range of delivery options serving the broadest multidisciplinary physician base, we believe we are uniquely positioned to accelerate this conversion.
And turning now to our U.S. regulatory activities, our C-Guardians U.S. IDE trial continues at a robust pace for enrollment, with 20 active trial sites recruiting and treating patients. We recently announced that on May 1, the first patient was successfully treated in our C-Guardian's trial utilizing CGuard Prime, the company's next-generation CAS stent platform. This marks a very significant milestone for the company, with CGuard Prime used in a clinical setting, marking a significant step forward in advancing more stenting procedures.
Since that first case, we've continued to rapidly enroll in the final patient set with CGuard Prime, anticipating completion of enrollment by the end of this quarter. As a reminder, the new CGuard Prime offers numerous benefits and advantages to physicians performing carotid revascularization, including an innovative handle design and catheter and TIP construction, which makes stent trackability and deployment much easier.
This gives physicians and staff a much higher degree of confidence, which we believe will contribute to its confidence in stent utilization once approved and launched. After completing enrollment in C-Guardians, we will advance our PMA submission and approval process to get us closer to the potential launch of CGuard prime in the U.S. market.
In parallel, we've commenced critical commercial readiness activities in the U.S., including the hiring of Sean Gleason, a seasoned commercial executive in the vascular space, to lead our go-to-market preparation as the GM of the Americas.
In terms of product pipeline, the CGuard EPS stent platform remains the core of our business as we focus on the value of the implant as the single most important variable in patient outcomes. To fully realize the full potential of CGuard, however, we've developed 2 new delivery platforms to drive utilization across the broadest vascular specialist community.
As noted earlier, we continue to advance development, regulatory approval and launch plans for our CAS platform, CGuard Prime, which will be available in both standard and short shaft versions, compatibility with development of SwitchGuard, our TCAR neuroprotection platform. In combination, we believe our Trans Carotid kit will enhance TCAR utilization with the best implant.
We believe the breadth of our total tool set, with its stent centric focus, will be a key differentiator for us as we work to unlock the tremendous potential of this rapidly evolving market segment. The wins of change and focus on endovascular first and carotid revascularization reinforce that our investment in this space will yield tremendous value as we work to lead this market transition.
In summary, we're incredibly proud of this financing, which serves as a proxy of our direction and is a transformational time for our company as we look for a bright future.
With that, I'll turn the call over to Craig for a review of the first quarter financials. Craig?
