Thanks, Marvin. For the 3 months ended September 30, 2023, revenue was $1,556,000 compared to $1,431,000 during the 3 months ended September 30, 2022.
This revenue increase of $125,000 was predominantly driven by an increase in commercial sales of $166,000 of CGuard EPS to existing geographies, offset by a $41,000 decrease in the United States as we completed in June 2023, as the enrollment of all patients in the C-Guardians IDE clinical trial. And accordingly, there was no further enrollments in the 3 months ended September 30, 2023. For the 3 months ended September 30, 2023, gross profit increased by 19.7% to $438,000 from $366,000 during the same period in 2022.
This increase in gross profit resulted from an $85,000 increase in revenues less the associated related material and labor, offset by miscellaneous expenses. Gross margin increased to 28.1% during the 3 months ended September 30, 2023 from 25.6% during the 3 months ended September 30, 2022, driven by the factors just mentioned. Total operating expenses for the third quarter of 2023 or $6,077,000, an increase of $1,101,000 or 22.1% compared to $4,976,000 for the third quarter of 2022. This increase was predominantly due to an increase in compensation expenses.
Total financial income for the third quarter of 2023 was $461,000 an increase of $380,000 or 469% compared to $81,000 for the third quarter of 2022. This increase was primarily due to a $412,000 increase in interest income from investment in marketable securities, money market funds and short-term bank deposits. Net loss for the third quarter of 2023 totaled $5,178,000 or $0.15 per basic and diluted share compared to a net loss of $4,529,000, or $0.58 per basic and diluted share for the same period in 2022. As of September 30, 2023, cash, cash equivalents and short-term investments and bank deposits were $43 million compared to $17.8 million as of December 31, 2022.
That concludes our prepared remarks. We will now open the call for questions. Operator?
