| Compensation Actually Paid vs. Total Shareholder Return [Text Block] | CAP and Cumulative TSR As demonstrated by the below graph, the amount of CAP to Mr. Kiani and the average amount of CAP to the Company’s Non-PEO NEOs as a group is aligned with the Company’s cumulative TSR over the three-year period presented in the table. The alignment of the CAP with the Company’s cumulative TSR over the period presented is because a significant portion of the CAP to Mr. Kiani and to the Non-PEO NEOs is comprised of equity awards. As described in more detail in the section “Executive Compensation—Compensation Discussion and Analysis,” the Company targets that approximately 75% of the value of total compensation awarded to the PEO and the Non-PEO be at-risk, which is comprised of equity awards, including performance-based RSUs and stock options. | | |
| Compensation Actually Paid vs. Net Income [Text Block] | CAP and Net Income As demonstrated by the below graph, the amount of CAP to Mr. Kiani and the average amount of CAP to the Company’s Non-PEO NEOs as a group is generally aligned with the Company’s net income over the three-years presented in the graph. While the Company does not use net income as a performance measure in the overall executive compensation program, the measure of net income is correlated with the measure of Adjusted Product Revenue, which the Company uses in setting goals in the Company’s incentive compensation plans and the performance-based RSUs that are awarded to the PEO and Non-PEO NEOs. As described in more detail in the section “Executive Compensation—Compensation Discussion and Analysis,” the Company targets that approximately 61.8% of the value of total compensation awarded to the Non-PEO NEOs (and approximately 84.8% of the value of total compensation awarded to the PEO) consists of amounts determined under the Company long-term incentive compensation program. | | |
| Compensation Actually Paid vs. Company Selected Measure [Text Block] | CAP and Adjusted Product Revenue As demonstrated by the below graph, the amount of CAP to Mr. Kiani and the average amount of CAP to the Company’s Non-PEO NEOs as a group is generally aligned with the Company’s Adjusted Product Revenue over the three year period presented in the table. While the Company uses numerous financial and non-financial performance measures for the purpose of evaluating performance for the Company’s compensation program, the Company has determined that Adjusted Product Revenue is the most important financial performance measure that is linked to the CAP for the PEO and the Non-PEO NEOs, for the most recently completed fiscal year. The Company utilizes Adjusted Product Revenue when setting goals in the Company’s incentive compensation plan. As described in more detail in the section “Executive Compensation—Compensation Discussion and Analysis,” the Company targets that approximately 75% of the value of total compensation awarded to the PEO and the Non-PEO NEOs consists of amounts determined under the Company incentive compensation plans to be comprised of performance-based RSUs and stock options. | | |
| Total Shareholder Return Vs Peer Group [Text Block] | Relative TSR and Nasdaq Medical Equipment Index TSR As demonstrated by the below graph, the Company’s cumulative TSR over the three year period presented in the table was 7%, while the cumulative TSR of the Nasdaq Medical Equipment Index, was 24% over the three years presented in the table. The Company’s cumulative TSR has historically outperformed the Nasdaq Medical Equipment Index during the three years presented in the graph, representing the Company’s superior financial performance as compared to the companies comprising the Nasdaq Medical Equipment Index.

| Compensation Actually Paid vs. Other Measure [Text Block] | CAP and Adjusted Non-GAAP Operating Profit As demonstrated by the below graph, the amount of CAP to Mr. Kiani and the average amount of CAP to the Company’s Non-PEO NEOs as a group is generally aligned with the Company’s Adjusted Non-GAAP Operating Profit over the three-years presented in the table. While the Company uses numerous financial and non-financial performance measures for the purpose of evaluating performance for the Company’s compensation program, the Company has determined that Adjusted Non-GAAP Operating Profit is a financial performance measure that, in the Company’s assessment, represents a relevant measure used by the Company to evaluate CAP to the Company’s PEO and Non-PEO NEOs. The Company utilizes Adjusted Non-GAAP Operating Profit when setting goals in the Company’s incentive compensation plans. As described in more detail in the section “Executive Compensation—Compensation Discussion and Analysis,” the Company targets that approximately 61.8% of the value of total compensation awarded to the PEO (and approximately 84.8% of the value of the total compensation awarded to the Non-PEO NEOs) consists of amounts determined under the Company’s incentive compensation plan to be comprised of performance-based RSUs and stock options. | | |
