Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	We assess, identify and manage risks from cybersecurity threats through our Global Cybersecurity and Compliance Program (Cybersecurity Program). Cybersecurity risks identified in the Cybersecurity Program are integrated into our Enterprise Risk Management Program. In addition, the Cybersecurity Program seeks to incorporate consideration of cybersecurity risk into our product development, business strategy, financial planning and capital allocation decisions. The Cybersecurity Program is currently overseen by the Board of Directors (Board) and is managed by our Chief Information Officer (CIO), who is currently serving as our interim Chief Information Security Officer (CISO) while we complete the search for a permanent CISO. The CISO's organization is responsible for cybersecurity strategy, policy, standards, risk-management architectures, and processes for the security of our corporate and manufacturing enterprise network, information assets and medical device technologies. Additionally, this organization provides governance and guidance related to secure-by-design principles and secure development practices for medical technologies. Our CIO has over 30 years of experience in information technology and has served in a number of professional services leadership roles, including as CIO over the past 15 years at three companies. The CISO’s organization monitors and manages, and works to identify and assess, cybersecurity risk through various technologies, resources, processes and policies that are updated as necessary to align with the changing threat landscape, our evolving business needs as well as global regulatory requirements. In addition, from time to time, we also utilize external auditors, assessors, and pen-testers to help evaluate the maturity of our Cybersecurity Program, including conducting penetration testing and vulnerability, risk, and maturity assessments. We also actively engage with industry experts, regulatory agencies, advocacy groups, industry peers, intelligence, and law enforcement communities as part of our continuing efforts to evaluate and enhance the effectiveness of our Cybersecurity Program and to stay abreast of the emerging cybersecurity landscape.

Additionally, we, in partnership with a third-party consultant, facilitate periodic cyber-crisis tabletop exercises with members of senior management (including our executive officers) to help us prepare for the occurrence of a significant cybersecurity event and our related response activities. Cybersecurity risks and threats, including any previous cybersecurity incidents, have not materially impacted us or our operations to date. However, we cannot provide any assurance that we will not be subject to a material cybersecurity incident in the future.
