What is a flow coupler?
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.
What is a microvascular coupler?
The Microvascular Anastomotic COUPLER Device is intended to be used in the anastomosis of veins and arteries normally encountered in microsurgical procedures only in the peripheral vascular system.
What is a venous coupler?
Most venous coupler devices use polyethylene rings with interlocking steel pins to securely connect blood vessels [6]. Various advantages of venous couplers have been described in the literature, including ease of handling, improved intimal alignment and reduced foreign material within the vessel lumen [6].
How do you use a venous coupler?
Pull the end of the first vein through the coupler lumen. Evert the vessel over the pins, and then secure the vessel on to the pins using the coupler forceps. Gentle traction is used to visualize the lumen of the vessel. Repeat the process for the second vein.
What is the purpose of vascular anastomoses?
A vascular anastomosis is a surgical procedure that is used to connect vessels to each other. Vascular procedures that require an anastomosis include: Coronary artery bypass surgery to treat a blocked artery supplying the heart. Connecting an artery to a vein for hemodialysis access.
How do surgeons connect blood vessels?
In an operation, two vessels are placed through a ring, folded back, and impaled on the pins. The two rings are then pressed together, forming a secure connection: a successful anastomosis.
How do surgeons attach veins?
A flow coupler (made by Synovis MCA) is a tiny implant that can be used to reconnect small veins during microvascular surgery. The implant both connects two veins together and monitors blood flow through the vein using a tiny ultrasonic Doppler probe.
How do blood vessels reconnect after surgery?
How serious is vascular surgery?
Like all surgeries, vascular surgery poses some risks of complications, which increase if the patient smokes, is obese, and has other serious conditions like chronic lung disease. There is additional risk when the surgeon operates on the chest or a major blood vessel.
What type of suture is used for vascular anastomosis?
This technique of vascular anastomosis requires a double-armed polypropylene suture placed in a continuous fashion with perpendicular bites located 1 mm from the vessel edge and 1 mm apart.
Is it possible to reattach nerves?
Sometimes a section of a nerve is cut completely or damaged beyond repair. Your surgeon can remove the damaged section and reconnect healthy nerve ends (nerve repair) or implant a piece of nerve from another part of your body (nerve graft). These procedures can help your nerves regrow.
How do surgeons put arteries back together?
Frequently, veins or arteries are stitched together using sutures. Another joining option, however, calls for the Synovis GEM Coupler, an implantable anastomosis product from the Birmingham, AL-based medical device manufacturer Synovis Micro.
What is flow coupler device?
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.
What is the microvascular anastomotic coupler system?
The Microvascular Anastomotic COUPLER System has been specifically designed for use in the anastomosis of veins and arteries normally encountered in microsurgical procedures. The COUPLER is intended for use with veins and arteries having an outside diameter no smaller than 0.8mm and no larger than 4.3mm and a wall thickness of 0.5mm or less. 1
What are Synovis products?
e Synovis product portfolio includes Coupler , Flow Coupler and Ge M MicroClip. ese products are used for joining small diameter vessels during autologous tissue breast reconstruction; sealing small blood vessels; in head, neck and hand procedures.
What are flow coupler rings made of?
FLOW COUPLER rings are made of high-density polyethylene and surgical grade stainless steel pins with a Teflon coated doppler probe.FLOW COUPLER rings are available in 2mm,2.5mm,3mm,3.5mm and 4mm sizes. The new improved second generation insulated silver coated copper coaxial lead is less sensitive to noise and signal interference. Advantages*
