  • 1.  Intended Uses, are they same or are they different?

    Posted 13-Feb-2017 22:36
    I'd like to pose this question to a greater audience in this community, below are the two intended use statements for device A and device B.  I hope to understand if you consider device A&B are having the same or similar intended  uses or not?

    “The device A is intended for use in diagnostic and operative endoscopic procedures to provide illumination and visualization of an interior cavity of the body through either a natural or surgical opening. The device A is intended for use with a compatible Camera Head and other accessory devices including an endoscope, optical coupler, and light cable. “

    “The device B is intended for use in diagnostic and operative endoscopic procedures to provide illumination and visualization through either natural or surgical openings of interior cavities of the body, hollow body organs or joint spaces. The device B is intended to be used in a surgical setting by personnel trained in endoscopic procedures with a compatible camera head and other accessory devices including an endoscope, light cable, display and potentially image recording devices.”

    When you add "hollow body organs or joint spaces.", You are going specific and therefore this is not the same indications for use. This may open to additional indications.
    When you add "... display and potentially image recording devices." You are adding constraints to the intended use. The environmental constraints of use have changed and you need to demonstrate that the device is effective and safe in that new environment.

    Hi Lin,

    I don't think I would not consider hollow body organs or joint spaces the same as body cavities. Having to get there could affect the design. I suspect you would need to provide good justification on that.

    The Indications for Use statements are the same.  No new devices or patient population.

    Different hypothetical:
    What if original 510k includes patient population of adults and children, but the newly modified device is strictly for children?  Does this require a traditional 510k or will a Special suffice?

    Are these from the official Indications for Use Statement in the 510(k) clearance?  If so, you should keep in mind that FDA has said that "intended use" and "indications for use" are not the same thing.

    The same in what sense?  Clearly the two statements are not identical.  Are you asking whether they are different "enough" that the one could not serve as the predicate for the other?  Or if they are different "enough" that both could not be accommodated under the same 510(k), and that each would need its own 510(k) instead?

    Yes, it is from the official 510(k) clearance letter from the FDA website, the cleared indication for use statement is “The device A is indicated for use in diagnostic and operative endoscopic procedures to provide illumination and visualization of an interior cavity of the body through either a natural or surgical opening.  The device A is indicated for use with a compatible  <company> Camera Heard and other accessory devices including an endoscope, optical coupler, and light cable.”   Then on the 510(k) summary letter under the intended use section, the same verbiage was used for this device A’s intended use.  In this case the indication for use/intended use statement is the same.  Under intended use section of the 510(k) summary, it also spelled out that “the device A is intended for use n endoscopic procedures without limit to the decease or condition being treated by the treating physician.  The device A is intended for use with patients undergoing endoscopic procedures for which the treating surgeon desires external video display and/or illumination.”  I think it is general enough to cover endoscopic procedures without going into details.  In this case, the indication for use and intended use statements were used interchangeability.  I see that happen quiet often on cleared 510(k)s.  My take is that this device only really requires intended use statement, however since 510(k) requires an indication for use statement, some company just cut and paste the same verbiage into that FDA’s indication for use statement FORM. 

    If I have a new device, “The device B is indicated for use in diagnostic and operative endoscopic procedures to provide illumination and visualization through either natural or surgical openings of interior cavities of the body, hollow body organs or joint spaces. The device B is intended to be used in a surgical setting by personnel trained in endoscopic procedures with a compatible camera head and other accessory devices including an endoscope, light cable, display and potentially image recording devices.”  

    Even though the spell out of the verbiage tried to separate the indication for use and  intended use statements for device B, however in FDA’s 2014 SE Guidance, FDA had indicated the intended use encompass the indication for use, therefore I would say when submitting a 510(k), I would consider the the intended uses of the device B is the combination of indication for use and intended use in the above paragraph (see my original post for device B).


    Julie, I am comparing the two intended uses (see my original post) and hope to understand if you consider device A&B are having the same intended use or not?  Like you said, clearly the two statements are not identical, if A & B are considered NOT having the same intended uses (or different enough), then using A as a predicate for B would not be sufficient as FDA requires predicate and subject devices must have the same intended uses.  I would think that the A&B are having the same intended uses in the context of “used in endoscopic procedure to provide illumination and visualization” whether it is through either natural or surgical openings of interior cavities of the body, hollow body organs or joint spaces.  I am wondering if anyone would recommend to remove these verbiage of hollow organs or joint spaces to be on the safe side of FDA's "intended uses must be the same" for SE determination?

    Hi Lin,
    If you have not read it yet, I recommend FDA guidance on General/Specific Intended Use, that should clear up some confusion around differences between intended use and indications for use, as well as general vs specific indications.
    http://www.fda.gov/MedicalDevices/DeviceRegulationandGuidance/GuidanceDocuments/ucm073944.htm

    I also recommend a great article by DuVal Law that provides additional insight: http://duvalfdalaw.com/resources/documents/client-alerts/fdas-current-interpretation-of-510k-general-vs-specific-use--through-the-eye-of-a-needle.pdf

    Based on my previous experiences with FDA, I am almost positive that "joint spaces" will be considered a more specific, and thus different indicated use. Hollow body organs is on the edge - it might be deemed equivalent to "a natural" body opening, but it might not.

    I would not assume this predicate, in and of itself, would support the proposed wording for Device B

    Ginger, thank you for the insight. Hollow body organs is fine in this case, FDA just made SE determination in a similar case in December 2016, so I am confident about that.   The  joint space is on the edge - however the joint space intended use is covered in the component's 510(k) <let me call it component a> hat was cleared many years ago, the same component is an 510(k) exampt device at the descretion of the FDA at this time until they issue the final rule (which could be in the next 3-4 months).  The device A is a combination of component a (Class II 510(k) exempt device by itself, and component b (class I device), the safe use of individual components have been established for decades. The functions f the combined device do not really change.
