Do I need a full validation of QPack, or is Orcanos COC is enough?

What is COC: Type Approval or Certificate of Conformity is granted to a product that meets a minimum set of regulatory, technical and safety requirements.

Orcanos provides this certification for its customers, but the question whether its instead of QPack validation, well, in some places it is enough, for example in Europe (CE), and in some places its not, such as in US, FDA, where the medical device manufacturer must do a full validation of any IT software he uses, based on the intended use.

You need to check with your regulatory consultant about it.

How does medical device classification really being set?

It is not feasible economically nor justifiable in practice to subject all medical devices to the most rigorous conformity assessment procedures available. A graduated system of control is more appropriate. In such a system, the level of control corresponds to the level of potential hazard inherent in the type of device concerned. A medical device classification system is therefore needed, in order to apply to medical devices an appropriate conformity assessment procedure.

The classification of medical devices is a ‘risk based’ system based on the vulnerability of the human body taking account of the potential risks associated with the devices. This approach allows the use of a set of criteria that can be combined in various ways in order to determine classification, e.g. duration of contact with the body, degree of invasiveness and local vs. systemic effect.

According to the ISO 62304 Section 4.3 it is being said:

Software safety classification shall be done in accordance to the following guidance:

a) The MANUFACTURER shall assign to each SOFTWARE SYSTEM a software safety class (A, B, or C) according to the possible effects on the patient, operator, or other people resulting from a HAZARD to which the SOFTWARE SYSTEM can contribute. The software safety classes shall initially be assigned based on severity as follows:

Class A: No injury or damage to health is possible
Class B: Non-SERIOUS INJURY is possible
Class C: Death or SERIOUS INJURY is possible

If the HAZARD could arise from a failure of the SOFTWARE SYSTEM to behave as specified, the
probability of such failure shall be assumed to be 100 percent. If the RISK of death or SERIOUS INJURY arising from a software failure is subsequently reduced to an acceptable level (as defined by ISO 14971) by a hardware RISK CONTROL measure, either by reducing the consequences of the failure or by reducing the probability of death or SERIOUS INJURY arising from that failure, the software safety classification may be reduced from C to B; and if the RISK of non-SERIOUS INJURY arising from a software failure is similarly reduced to an acceptable level by a hardware RISK CONTROL measure, the software safety classification may be reduced from B to A.

 

Where the Lines Blur

For more than 90% of products, classification is very clear. Still, certain products cause confusion, and what may seem like an ordinary device might be considered a medical device or a drug (or combination, such as a drug-eluting stent) depending on claims and how it is used.

In conclusion, the first regulatory step toward European device compliance is to determine whether your device is considered to be a device and, if so, what the classification will be for Europe. You simply cannot let this determination be based on the US classification of your device.

 

 

510(k) Clearance and PMA

February 23rd, 2011 Posted by 510(k), Pre Market Approval (PMA), Software Lifecycle Management 0 thoughts on “510(k) Clearance and PMA”

PMA = Pre Market Approval

Risk Classification

Class I: Simple devices with a minimal risk to the user. Most of these devices are exempt from FDA clearance or approval. Examples: crutches, elastic bandages, bedpans.

Class II: Moderate level of risk to the user. Almost all of these devices require a regulatory submission before they can be legally marketed. As a rule, class II devices require 510(k) submissions. Examples: administration sets, sutures, inflatable blood pressure cuffs.

Class III: These devices pose a serious level of risk to the user, mostly because they are implants or sustain life. All of these devices require a regulatory submission before they can be legally marketed. As a rule, class III devices require a PMA (Premarket Approval) submission. Examples: implantable pacemakers, blood vessel stents, breast implants.

510(k) Clearance
The purpose of a 510(k) submission is to demonstrate that a device is “substantially equivalent” to a predicate device. The 510(k) submitter compares and contrasts the subject and predicate devices, explaining why any differences between them should be acceptable. Manufacturers may also submit a 510(k) if they alter their device. Not all changes require a 510(k) submission. In general, changes to a device’s intended use, contraindications, or basic operation require a new 510(k) clearance. Changes to blood-contacting materials, sterilization method, or performance specifications may also require a new 510(k).

The FDA does not “approve” 510(k) submissions. It “clears” them.

Premarket Approval (PMA)

A PMA submission is used to demonstrate to the FDA that a new or modified device is safe and effective. This standard is higher than is required for 510(k) submissions. Human use data from a formal clinical study is almost always required in addition to laboratory studies.

PMA devices can be legally advertised as “PMA-approved” or “FDA-approved.”
