Device Description
The Carr-Locke and Articulator Injection Needles are single use, disposable, flexible sheath injection needles that are intended to be used for the injection of various types of media through flexible endoscopes. All the needles have the same general design and consist of a handle luer, a handle hypo tube, a compression spring (except for PN 00711808), a PEEK tube, a spring sheath, a distal hub and an injection needle. The Carr-Locke and Articulator needles are sterile, disposable devices that are used through the working channel of flexible endoscopes for the purpose of injecting media into the gastrointestinal tract.
More Information

No
The summary describes a mechanical injection needle and does not mention any software, algorithms, or AI/ML capabilities.

No
The device is described as an "injection needle" used for injecting "various types of media" through endoscopes, and its predicate device is a "Sclerotherapy Needle." While sclerotherapy is a therapeutic procedure, the device itself is an instrument used to deliver substances, not a therapeutic device that inherently treats a condition.

No
The device description states it is intended for the "injection of various types of media through flexible endoscopes" into the gastrointestinal tract. This describes a therapeutic or interventional function, not a diagnostic one.

No

The device description clearly outlines physical components such as needles, sheaths, tubes, and a handle, indicating it is a hardware medical device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is for the "injection of various types of media through flexible endoscopes." This describes a procedure performed on the patient, not a test performed on a sample taken from the patient.
  • Device Description: The description details a physical device used for injection, not a reagent, instrument, or system intended for the examination of specimens derived from the human body.
  • Lack of IVD Characteristics: There is no mention of analyzing samples, detecting substances, or providing diagnostic information based on laboratory testing.

IVD devices are used to perform tests on samples like blood, urine, tissue, etc., to diagnose diseases or conditions. This device is used for delivering substances directly into the body during an endoscopic procedure.

Device Description

The Carr-Locke and Articulator Injection Needles are single use, disposable, flexible sheath injection needles that are intended to be used for the injection of various types of media through flexible endoscopes. All the needles have the same general design and consist of a handle luer, a handle hypo tube, a compression spring (except for PN 00711808), a PEEK tube, a spring sheath, a distal hub and an injection needle.

The Carr-Locke and Articulator needles are sterile, disposable devices that are used through the working channel of flexible endoscopes for the purpose of injecting media into the gastrointestinal tract. Once the device is unpackaged from the sterile packaging, the user can purge the needle assembly of air by attaching the injection container (i.e. a syringe) to the proximal luer and dispensing 0.5 - 0.75 ccs of media. After purging the device, the user ensures the needle is fully retracted into the catheter of the device by slowly twisting the proximal luer until it disengages from the distal luer. Once verified that the needle has been fully retracted into the catheter, the user threads the catheter through the working channel of the endoscope. Once the needle has been threaded through the endoscope and the injection site has been reached, the user can lock the needle into the deployed position by pressing the proximal luer against the distal luer and then turning the proximal luer until it stops. The needle can then be inserted into the mucosa of the gastrointestinal tract. Once the needle has been inserted, the desired injection media can be administered to the patient via the distal luer connection. Once injection is completed, the user can retract the needle by disengaging the proximal and distal luers and allowing the compression spring to pull the needle into the sheath or by physically grasping the proximal luer and pulling in the proximal direction until the needle enters the sheath (PN 00711808). Once the needle is retracted, the user can then remove the device from the endoscope.

3. Description of Device

The Carr-Locke and Articulator Injection Needles are single use, disposable, flexible sheath injection needles that are intended to be used for the injection of various types of media through flexible endoscopes. All the needles have the same general design and consist of a handle luer, a handle hypo tube, a compression spring (except for PN 00711808), a PEEK tube, a spring sheath, a distal hub and an injection needle.

The Carr-Locke and Articulator needles are sterile, disposable devices that are used through the working channel of flexible endoscopes for the purpose of injecting media into the gastrointestinal tract. Once the device is unpackaged from the sterile packaging, the user can purge the needle assembly of air by attaching the injection container (i.e. a syringe) to the proximal luer and dispensing 0.5 - 0.75 ccs of media. After purging the device, the user ensures the needle is fully retracted into the catheter of the device by slowly twisting the proximal luer until it disengages from the distal luer. Once verified that the needle has been fully retracted into the catheter, the user threads the catheter through the working channel of the endoscope. Once the needle has been threaded through the endoscope and the injection site has been reached, the user can lock the needle into the deployed position by pressing the proximal luer against the distal luer and then turning the proximal luer until it stops. The needle can then be inserted into the mucosa of the gastrointestinal tract. Once the needle has been inserted, the desired injection media can be administered to the patient via the distal luer connection. Once injection is completed, the user can retract the needle by disengaging the proximal and distal luers and allowing the compression spring to pull the needle into the sheath or by

physically grasping the proximal luer and pulling in the proximal direction until the needle enters the sheath (PN 00711808). Once the needle is retracted, the user can then remove the device from the endoscope.

4. Intended Use/Indications for Use

These single use, disposable, flexible sheath injection needles are intended to be used for the injection of various types of media through flexible endoscopes.

ર. Summary of Nonclinical Tests

The Carr-Locke and Articulator Injection needles have a similar intended use and the same technological characteristics. The minor design differences and minor differences in intended use do not raise different questions of safety and effectiveness as compared to the predicate device. Testing to assess and demonstrate substantial equivalence to the predicate is summarized below:

6. Conclusion

Based on the intended uses, technological characteristics and non-clinical performance data, the subject device is as safe, as effective and performs at least as well as the legally marketed predicate device K212668, Class II (21 CFR 876.1500), product code FBK.
