|The Freedom Inguinal Hernia Repair System with PROFLOR™|
|What is the Freedom Inguinal Repair system|
The spring like structure is able to be compressed, but unlike other implants, it will spring back open. This radial recoil is a key part to how the device holds itself into the hernia opening without the need for fixation with sutures, tacks or tissue glues.
The unique open architecture of the implant means that is has no dense central core. This allows the implant to be compressed vertically when in the patient. This acts like a shock absorber under compression. The mixture of radial resilience and vertical shock absorbance make the implant very compliant when placed into the abdominal wall.
|What kind of implant is it?|
The device is a 3 Dimensional implant designed to completely fill the defect, rather than just cover it.
Current plugs are conical shaped, folded mesh that have no inherent resilience or pre-peritoneal disk. The problem with these types of plugs is that they have very dense regions of mesh at the "nose" of the plug and clinical studies have shown that plugs can shrink up to 70% volumetrically 
ProFlor has a cylindrical shape with no "nose", plus a pre-peritoneal disk which covers the surface of the core, protecting the spaces between the lamella while tissue grows in.

|Won't all that material cause fibrosis?|
Although ProFlor at first glance seems have a lot of material, it is actually comparable in weight to plugs with an onlay mesh, or systems like Ethicon PHS® . Although the "amount" of material is an important factor in how fibrosis can occur, both material and geometrical structure also play an important role. The rear disk, and the lamella walls are made from light weight, large pore PP mesh. The open structure means that the overall density of the implant is very low.
It should be noted that foreign bodies placed into patients have the potential to cause fibrotic and other adverse reactions. You should always counsel patients thoroughly regarding the placement and possible need for removal or revision of permanent implants.
Insightra has conducted extensive pre-clinical studies in the porcine animal model to look at the level of inflammatory reaction to the implant, which was seen to be in line with standard PP implants. They also looked at the quality of tissue ingrowth  which was published in Artificial Organs.

|Pre-clinical & Clinical data|
Since 2007 Insightra Medical has been supporting reasearch into pre-clinical data regarding the biology of hernia disease. At the same time they have been studying the ProFlor Implant in animal models, and the tissue reactions associated to it. It has studied the device clinically through investigator sponsored studies. A summary of the clinical data can be found within the Technique Guide.

Information on Surgical Mesh for Hernia Repairs
Hundreds of thousands of hernia repair operations are performed each year both with and without surgical mesh, and patients generally recover quickly and do well after surgery.
However, FDA has received reports of complications associated with the mesh. The complications include adverse reactions to the mesh, adhesions (when the loops of the intestines adhere to each other or the mesh), and injuries to nearby organs, nerves or blood vessels . Other complications of hernia repair can occur with or without the mesh, including infection, chronic pain and hernia recurrence.
Most of the complications reported to us so far have been associated with mesh products that have been recalled and are no longer on the market. For further information on the recalled products, please visit the FDA Medical Device Recall website.
We are continuing to analyze and evaluate incoming reports of adverse events, and are speaking with patients, surgeons and researchers. We will inform the public as new information becomes available.
Talking to your doctor
There are also certain questions you should consider asking your surgeon:
What are the pros and cons of using surgical mesh in my particular case?
You can report any problems to the FDA's MedWatch Adverse Event Reporting program either online, by regular mail or by FAX.
