The description focuses on mechanical coupling and Doppler ultrasound for blood flow detection, with no mention of AI or ML for analysis or interpretation.
No
The device is used for mechanical connection of vessels and detection of blood flow, not for therapeutic purposes.
Yes
The device is intended to "detect blood flow and confirm vessel patency intraoperatively and post-operatively at the anastomotic site," which are diagnostic functions.
No
The device description clearly outlines hardware components including implantable rings, a Doppler probe, and a monitor unit.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This testing is done outside of the body.
- Flow COUPLER Function: The Flow COUPLER Device and System are used directly on the patient's blood vessels during and after surgery. The Doppler probe detects blood flow in vivo (within the living body).
The device is an implantable surgical device with a component for monitoring blood flow in vivo using ultrasound. This falls under the category of medical devices used for treatment and monitoring within the body, not for in vitro diagnostic testing of specimens.
N/A
Intended Use / Indications for Use
The Flow COUPLER Device is a single use, implantable device that is intended to be used in the end-to-end anastomosis of veins and arteries normally encountered in microsurgical and vascular reconstructive procedures. The Flow COUPLER Device includes a pair of permanently implanted rings which secure the anastomosis and a removable Doppler probe that is press-fit onto one of the rings. When the Flow COUPLER Device is used in conjunction with the Flow COUPLER Monitor, the Flow COUPLER System is intended to detect blood flow and confirm vessel patency intraoperatively and post-operatively at the anastomotic site. Post-operatively, blood flow can be detected on an as needed basis for up to 7 days. The Flow COUPLER Doppler probe is not intended to be a permanent implant and should be removed 3 to 14 days post-operatively.

Device Description
The Flow COUPLER System consists of a Flow COUPLER Device and a Flow COUPLER Monitor. The Flow COUPLER Device is a sterile, single-use implantable pair of rings molded out of high density polyethylene with stainless steel pins on each ring. The Flow COUPLER Device is designed to serve as a mechanical, sutureless device for connecting veins or arteries. A probe-holder feature is molded on one Flow COUPLER ring and serves as the press-fit point of attachment for a pre-attached 20 MHz Doppler probe. The Doppler probe connects to the Flow COUPLER Monitor unit, via the external lead.
The Flow COUPLER Monitor and Doppler probe is a pulsed Doppler ultrasound system designed for the detection of blood flow in vessels. An audible ultrasonic signal is produced when the Doppler probe detects blood flow.
The Flow COUPLER Device and System has been specifically designed for use in end-to-end anastomosis of blood vessels and the detection of blood flow at the anastomotic site. On an as needed basis, blood flow can be detected for up to 7 days. The Flow COUPLER rings are intended to be a permanent implant. The Flow COUPLER probe is not intended to be a permanent implant; the probe should be removed, by gentle traction on the external lead, 3 to 14 days post-operatively.

Dear Mr. Thome:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you; however, that device labeling must be truthful and not misleading.

Flow COUPLER Device is designed to serve as a mechanical,
sutureless device for connecting veins or arteries. A probe-holder
feature is molded on one Flow COUPLER ring and serves as the
press-fit point of attachment for a pre-attached 20 MHz Doppler
probe. The Doppler probe connects to the Flow COUPLER
Monitor unit, via the external lead.
The Flow COUPLER Monitor and Doppler probe is a pulsed
Doppler ultrasound system designed for the detection of blood flow
in vessels. An audible ultrasonic signal is produced when the
Doppler probe detects blood flow.
The Flow COUPLER Device and System has been specifically
designed for use in end-to-end anastomosis of blood vessels and the
detection of blood flow at the anastomotic site. On an as needed
basis, blood flow can be detected for up to 7 days. The Flow
COUPLER rings are intended to be a permanent implant. The Flow
COUPLER probe is not intended to be a permanent implant; the
probe should be removed, by gentle traction on the external lead,
3 to 14 days post-operatively. |
