When designing a catheter, shaft performance is often where success or failure is determined. Pushability, torque response, flexibility, and kink resistance all depend heavily on catheter shaft design and reinforcement strategy. One of the most important design decisions in catheter development is how the shaft is reinforced. Most engineers think of reinforcement as a choice…

Sterilization validation is one of the final steps before a medical device moves toward regulatory submission or commercialization. For many teams, it also becomes a bottleneck. Validation studies can take months to complete, especially when a new sterilization cycle must be developed from the ground up. But in many cases, there is a more efficient…

Verification and Validation (V&V) testing is a critical milestone in medical device development. It’s where teams generate objective evidence that a device meets design requirements and performs as intended. Yet many V&V programs run into delays, failed tests, or repeated studies. In most cases, the issue isn’t the testing itself, it’s how the program was…

As a medical device approaches regulatory submission or commercialization, the focus shifts from design iteration to verification and validation (V&V). This phase provides objective evidence that the device meets design requirements, performs as intended, and is safe for clinical use. For minimally invasive devices such as catheters, delivery systems, and implants, a complete V&V program…

Scaling a catheter program is not simply about increasing production volume. It is about increasing maturity across four critical areas: device design, manufacturing process, quality system, and cost structure. Most catheter programs move through three distinct phases: Each phase serves a distinct purpose. When expectations are aligned with that purpose, catheter scale-up becomes predictable, controlled,…

Women’s health has been underrepresented in medtech for far too long.Not because the clinical needs are small, but because they have often been treated as niche. We do not see it that way. At Medical Murray, women’s health is not a side category or a temporary focus. It is a critical and growing area of…

Pulse field ablation (PFA) is rapidly transforming electrophysiology (EP). Its non-thermal mechanism, tissue selectivity, and reduced collateral damage have accelerated interest in next-generation PFA mapping and ablation catheters. At the same time, many EP catheter development programs stall before commercialization. Funding constraints, underestimated technical complexity, and late-stage manufacturing surprises are common. While full-scale PFA production…

IVUS and OCT each offer something valuable in intravascular imaging. IVUS gives deeper visualization through blood and plaque, while OCT provides very fine detail close to the vessel wall. For years, companies have treated them as separate tools because the engineering needs behind each system are so different. Now more teams are trying to bring…

Embolic filters protect downstream vessels while thrombectomy devices actively remove clots, but both face the same engineering challenge: capturing debris is only step one. The true test of a device is what happens after the material is captured. What happens after material is captured ultimately determines whether a device is safe, effective, and clinically successful.…

Braiding is a core technique in many interventional medical devices. Most people know braiding from its role in reinforcing catheter shafts, but it also plays a critical role in devices like thrombectomy tools, embolic filters, septal occluders, left atrial appendage (LAA) implants, and even some stents. The braid pattern and material choice have a big…
