Full disclosure before the Q&A: I am not a surgeon or a radiologist. I am the quality/compliance person at a medical device distributor. I review every product before it goes into our catalog — roughly 200 unique items a year, sometimes more. In the first half of 2025, my own review log showed about 10% of first submissions were rejected because the IFU, label, or calibration record did not match the purchase order. That shapes my answers: I care less about what a product is supposed to do and more about how we know it does it.

This is not a complete product guide. It is a list of questions we actually get from hospital buyers and surgical teams, plus the details I usually add when I review the paperwork. You can jump to any section.

1. What does Globus Medical make?

Globus Medical is often described as a spine company, but the product range is wider than that. It makes spinal implants, surgical instruments, ExcelsiusGPS surgical navigation, imaging systems, patient monitoring products, diagnostic tools like ECG and pulse oximeters, dental equipment, rehabilitation aids, and energy devices.

If you are a hospital buyer, the main question is not whether the company exists; it is how the portfolio connects. Products tied to the NuVasive merger are now under the same corporate umbrella, though legacy part numbers may still appear on sterilization labels and invoices for a while. When I review a large quote, I do not assume one strong product line makes every line item equal. I check whether the specific item, software version, accessories, instructions for use, and supplier identification are consistent.

2. Who is David Paul? Why do people search for “david paul globus medical”?

David Paul is a co-founder of Globus Medical. He helped start the company in 2003, and his name appears in the company history section of investor materials. Search volume for “david paul globus medical” usually comes from people trying to figure out whether the founder is still connected to product decisions.

From my quality perspective, that is the wrong person to focus on. The product release process is not a founder approval chain. A current regulatory submission is approved by current responsible people — quality managers, regulatory affairs staff, notified bodies, and FDA or CE audit trails. That is a good thing, not a cynical thing. You want more than one set of eyes. If a founder’s name appears in an old article, keep scrolling. Ask to see the current IFU and any applicable 510(k)/CE documentation before you approve a vendor.

3. Is NuVasive now the same as Globus Medical?

Yes and no. Globus Medical completed a merger with NuVasive in 2023, and the combined company uses the Globus Medical name. NuVasive products and capabilities, especially lateral spine surgery and intraoperative monitoring, are now part of that broader offering.

The paperwork side is not always as clean as the marketing side. Legacy NuVasive registrations, unique device identifiers, and service histories may still exist under the original legal manufacturer. If someone says, “this is a NuVasive Globus Medical order,” I would ask which legal manufacturer name appears on the label and whether sterilization and traceability documents were updated. This is not a warning; it is a checklist item. In an audit, a mismatched manufacturer name is the kind of small detail that causes a week of email follow-ups.

4. What should I look for in a centrifuge machine?

A centrifuge machine is a motorized rotor that spins samples to separate materials by density. It can separate plasma from blood, cells from media, or precipitate material into a pellet. If you buy one without a protocol in mind, you often end up with either too much capacity or not enough speed for the application.

The most common mistake is buying by RPM alone. In quality reports, people list g-force because that is the physical parameter that matters. RPM only matters for a given rotor radius. A machine that spins 15,000 RPM with a small rotor might produce less force than a 10,000 RPM machine with a wider rotor. So match the unit to the tube size and the g-force in your procedure. I also check whether rotor life is documented, whether the machine has imbalance detection, and whether the lid interlock is easy for staff to use. A used centrifuge machine can be a fine purchase if there is a clear service record. Without one, the rotor itself is a hidden liability.

5. How do I choose an electronic pipette?

An electronic pipette uses a motor to move the piston, which helps with consistency and reduces thumb strain. In a busy lab, that has real benefits. But for me, the deciding factor is not the digital screen or the number of modes. It is calibration and service access.

Before selecting an electronic pipette, ask the manufacturer: where do you recalibrate this model? How long is a typical service turnaround? Can you provide a basic accuracy verification report after service? Are replacement O-rings available locally? The best pipette in the world is still a measuring instrument, and measuring instruments need periodic verification. I have seen labs buy eight identical units and then discover the only authorized service center is in another country. The units sat unused for three weeks waiting for a technician. If you need accuracy, you need a service plan, not just a feature list.

6. How does an MRI machine work?

An MRI machine creates images without ionizing radiation. It uses a strong, constantly active magnetic field to align hydrogen protons inside the body. Then it applies a radiofrequency pulse that tips those protons out of their aligned state. When the pulse is turned off, the protons relax back and release a small radio signal. Receiver coils and gradient coils turn that signal into spatial information, and a computer reconstructs the image.

My one-sentence version for non-radiology staff is: it is like listening to billions of tiny tuning forks after they are knocked out of a magnetized lineup.

When you buy an MRI system, do not let magnet strength be the only conversation. Safety screening, coil availability, room shielding, cryogen venting, software upgrades, and service response time matter just as much. I am not an MRI engineer. I am the person who asks to see the installation checklist and the preventive maintenance schedule before final approval.

7. What document should I ask for before buying any medical equipment?

This is the question people rarely ask: what records do you have that prove the exact unit is ready for use? New equipment comes with an IFU and a declaration of conformity. Used or refurbished equipment needs more. I would request the unit-specific service history, any calibration certificate or performance verification record, and the manufacturer’s field action notice list if the model has one.

Words like “works fine” are not traceability. I once reviewed a used imaging cart that was sold with a clean verbal history, and the serial number showed an incomplete field correction from the original manufacturer. It took three weeks to resolve. That experience changed how I order equipment. If the serial number does not match the records, or the record has a gap longer than a standard preventive maintenance interval, ask for an explanation before you send money.

All seven questions point to the same rule: product claims matter less than verification records. That is true whether you are looking at a Globus Medical quote, a NuVasive legacy part, a centrifuge machine, an electronic pipette, or an MRI scanner.
