Clarifying Questions (3 minutes)

• Context: I'm thinking about the current market position of the WATCHMAN FLX. Could you provide more insight into our market share and primary competitors?

Why it matters: Helps frame the urgency and potential impact of this trade-off. Expected answer: Market leader with 60-70% share, facing increasing competition. Impact on approach: Would influence how aggressively we need to optimize for ease of implantation vs. durability.

• Business Context: Based on our revenue model, I assume the device is sold directly to hospitals. Is this correct, and are there any unique pricing or reimbursement factors we need to consider?

Why it matters: Affects how we balance short-term sales (ease of implantation) with long-term reputation (durability). Expected answer: Correct, with reimbursement tied to successful outcomes. Impact on approach: Would emphasize the importance of balancing both factors for sustainable growth.

• User Impact: I'm considering both physicians and patients as key users. Are there specific physician segments (e.g., experienced vs. new implanters) we're particularly focused on?

Why it matters: Different user segments may have varying needs and preferences in this trade-off. Expected answer: Targeting both experienced users and expanding to new implanters. Impact on approach: Would necessitate a solution that caters to both ease of use and proven long-term results.

• Technical: Regarding the current design, what are the primary factors affecting ease of implantation, and how do they potentially impact long-term durability?

Why it matters: Identifies the core technical challenges and potential areas for innovation. Expected answer: Factors include device compressibility, deployment mechanism, and materials used. Impact on approach: Would guide where to focus our R&D efforts in resolving this trade-off.

• Timeline: Given the medical device industry's regulatory environment, what's our expected timeline for implementing significant design changes?

Why it matters: Influences the scope and nature of potential solutions we can consider. Expected answer: 2-3 years for major changes, 6-12 months for minor iterations. Impact on approach: Would determine whether we focus on immediate optimizations or longer-term innovations.
