What Are Cardiovascular Instruments? Types, Uses and FDA Class

This page describes products and general use; it is not medical advice.

Cardiovascular instruments are hand-held surgical instruments with special features for use in heart and blood-vessel surgery, such as forceps, retractors, scissors, clamps and needle holders. In US regulation the category “cardiovascular surgical instruments” is Class I, while one member of the family, the vascular clamp, is Class II. Who uses them: surgeons, scrub and perioperative nurses, and sterile processing staff in operating rooms.

What cardiovascular instruments are

The FDA defines cardiovascular surgical instruments as “surgical instruments that have special features for use in cardiovascular surgery,” and lists forceps, retractors and scissors as examples (21 CFR 870.4500). Searchers use several phrases for the same family: cardiac surgery instruments (heart operations), vascular surgery instruments (blood-vessel operations) and a “vascular instrument set” (a facility’s grouping of those instruments). They are one product class, covered together here.

Main instrument groups

The perioperative nursing association AORN describes the cardiothoracic instruments below by what each one does on the surgical field.

Group	Example	Purpose described by AORN
Retractors	Sternal retractor	Keeps the breastbone separated to give access to the heart and aorta; it stays in place for the whole procedure.
Retractors	Rultract	Exposes the internal mammary arteries; rakes attach to the sternum and elevate it.
Clamps	Derra partial occlusion clamp	Occludes a vessel partially, so some flow continues.
Clamps	DeBakey clamp	Deeper angle for deeper vessels such as the aorta; fully stops flow.
Clamps	Aortic cross clamp	Larger, more angled DeBakey-style clamp used to stop aortic flow during surgery; soft inserts make it atraumatic.
Clamps	Bulldog appliers	Temporary vessel occlusion; removed before surgery ends.
Clamps	Tubing clamps	Control flow in heart-lung machine tubing.
Needle holders	Coronary (Castro) holder	Smaller tips for microneedles, usually 5-0 and smaller.
Needle holders	Wire needle holder	Heavy holder used to load and pass sternal wires.
Scissors	Coronary scissors	Delicate scissors that cut vein and artery conduits.
Pickups and dilators	Scanlan pickups; coronary dilators	Pickups are used to position vein and artery conduit grafts; dilators are sized 1.0 mm and 1.5 mm (AORN).
Other	Rumel tourniquet passer; wire cutters, twisters and removers; battery-operated sternal saw	Control bleeding at cannulation sites; work with sternal wires; open the sternum.

How FDA classifies them

Under 21 CFR 870.4500, cardiovascular surgical instruments are Class I (general controls) and exempt from premarket notification (510(k)), subject to the limits in 21 CFR 870.9. Those limits mean the exemption applies only to a device that has the characteristics typical of its generic type; a device whose intended use or fundamental technology differs still needs a 510(k).

The vascular clamp is separate. 21 CFR 870.4450 defines it as “a surgical instrument used to occlude a blood vessel temporarily” and classifies it as Class II (performance standards). For clamp classes in more depth, see types of surgical clamps.

Instruments without a cardiovascular-specific feature fall under the general manual surgical instrument regulation, 21 CFR 878.4800 (nonpowered, hand-held or hand-manipulated, reusable or disposable; Class I). Specialty instruments are regulated under their own parts of the CFR, which is why cardiovascular instruments sit in Part 870.

Cardiac vs vascular instrument sets

Using the AORN descriptions, cardiac surgery work is characterised by sternal retractors, the aortic cross clamp and sternal wire instruments, while vascular and bypass-conduit work is characterised by clamps, bulldog appliers and conduit-handling instruments such as coronary scissors and coronary pickups. No FDA rule or standard fixes what a “vascular instrument set” or “cardiac set” contains: contents are set by each facility and the instrument supplier. For how FDA treats kits, see surgical pack contents and FDA classes.

Safe use and handling basics

• AORN notes that veins and arteries used for bypasses must be handled with care so they are not torn; this is why delicate scissors, pickups and atraumatic clamp inserts exist.
• Use each instrument only for the purpose its manufacturer’s instructions for use state, and follow those instructions for cleaning, inspection and sterilization.
• Bulldog appliers and other temporary clamps are removed before surgery ends, per AORN.

Common mistakes

• Treating “vascular clamp” and “cardiovascular surgical instruments” as one regulatory class: the clamp is Class II, the general category Class I.
• Assuming a set name defines its contents; no FDA rule fixes them.
• Assuming every instrument in the category is 510(k)-exempt without reading the 21 CFR 870.9 limits.

Frequently asked questions

What are cardiovascular instruments?

Surgical instruments with special features for use in cardiovascular surgery, for example forceps, retractors and scissors, as defined in 21 CFR 870.4500.

Are cardiac surgery instruments different from vascular surgery instruments?

They overlap. Both fall under the same FDA category; the practical difference is the operation, for example sternal retractors and aortic cross clamps for open-heart work, and clamps and conduit instruments for vessel work.

What is in a vascular instrument set?

There is no FDA-defined list. Contents vary by facility and supplier; typical members include clamps, needle holders, scissors and forceps.

What FDA class are cardiovascular instruments?

Class I and 510(k)-exempt subject to 21 CFR 870.9; vascular clamps are Class II.
