The product life cycle for medical devices typically includes several stages:

1. Introduction: This is the stage where a new medical device is introduced to the market. It involves research, development, and regulatory approval processes.
2. Growth: Once introduced, the device enters a phase of rapid sales growth as it gains acceptance among healthcare providers and patients. Manufacturers may expand production and distribution during this stage.
3. Maturity: In this phase, sales stabilize as the device reaches its peak market penetration. Competition may increase, leading to price pressures and the need for differentiation through innovation or added features.
4. Decline: Eventually, the device may face a decline in sales due to factors such as technological advancements, regulatory changes, or the emergence of superior alternatives. Manufacturers may decide to discontinue the device or invest in modifications to extend its life cycle.

Throughout these stages, manufacturers must also consider factors like regulatory compliance, customer feedback, and ongoing support and maintenance for the device.
