Covidien has enrolled 600 patients in its clinical study comparing use of Parietex ProGrip self-fixating mesh to the gold-standard suture-based Lichtenstein repair method for primary inguinal hernias.
The nine-site, international, prospective randomized trial was designed to compare patient outcomes, including pain, for one year following inguinal hernia repair with each method.
Parietex ProGrip self-fixating mesh has resorbable polylactic acid microgrips that enable surgeons to position and securely place the mesh without the need for sutures.
Principal investigator and Derriford Hospital, Plymouth, UK professor Andrew Kingsnorth said preliminary study results indicate that Parietex ProGrip self-fixating mesh simplifies hernia repair, allowing for faster operating time and less pain in the week following surgery compared to the gold-standard Lichtenstein repair method.
"We are encouraged by these findings and look forward to reviewing the final study data to confirm these initial promising results," Kingsnorth said.
