Abstract
An implantable prosthetic mesh for repair of an inguinal hernia. The prosthetic mesh includes a conforming soft mesh portion and two displaced portions each having a three dimensional shape and constructed of a stiffer mesh material. The soft mesh portion can be draped over the tissue and spermatic cords, and the two three-dimensional portions formed from the stiffer mesh material are adapted to enter into and be received deep within the respective space defined in the anatomy at each of direct and indirect spaces surrounding the inferior epigastric vessels.
Claims21
A method of repairing a tissue defect in a patient, the patient having on a medial side a direct space located between inferior epigastric vessels, a medial rectus muscle, and an iliopubic tract and a femoral ring defined between the inferior epigastric vessels, the iliopubic tract, and a spermatic cord, and on a lateral side an indirect space defined as lateral to the inferior epigastric vessels and anterior to the iliopubic tract, the method comprising:
- a) providing a prosthetic mesh having a relatively soft conforming first mesh material, and first and second three-dimensional portions of a stiffer second mesh material that are displaced from each other, each of the first and second three-dimensional portions having a first convex surface and an opposing second concave surface;
- and
- b) placing the first mesh material over the spermatic cord and the first and second three-dimensional portions at the direct and indirect spaces, respectively,
- wherein the convex surfaces of the first and second three-dimensional portions extend into the direct and indirect spaces to thereby anchor the prosthetic mesh relative to the tissue defect.
A method of repairing a tissue defect in a patient, the patient having on a medial side a direct space located between inferior epigastric vessels, a medial rectus muscle, and an iliopubic tract, and a femoral ring defined between the inferior epigastric vessels, the iliopubic tract, and a spermatic cord, and on a lateral side an indirect space defined as lateral to the inferior epigastric vessels and anterior to the iliopubic tract, the method comprising:
- a) providing a prosthetic mesh having first and second three-dimensional portions, each with a convex side, that are displaced from each other by a third mesh portion, each of said first and second three-dimensional portions having a stiffer mesh construction than said third mesh portion, the prosthetic mesh provided in a rolled form;
- b) inserting the rolled mesh into a laparoscopic port;
- c) advancing the rolled mesh out of the port to the site of tissue defect;
- and
- d) maneuvering the mesh so that,
- the first three-dimensional portion is located on the medial side and seated convex side down within the direct space,
- the second three-dimensional portion is located on the lateral side and seated convex side down within the indirect space, and
- the third mesh portion is draped across the epigastric vessels and spermatic cord.
A method of repairing a tissue defect in a patient, the patient having on a medial side a direct space located between inferior epigastric vessels, a medial rectus muscle, and an iliopubic tract and a femoral ring defined between the inferior epigastric vessels, the iliopubic tract, and a spermatic cord, and on a lateral side an indirect space defined as lateral to the inferior epigastric vessels and anterior to the iliopubic tract, the method comprising:
- a) providing a prosthetic mesh having a relatively soft tissue conforming first mesh material, and stiffer first and second convex mesh portions extending from the first mesh material and which are displaced from each other by the first mesh material;
- and
- b) placing the first mesh material over the spermatic cord, and the first and second convex mesh portions into the direct and indirect spaces, respectively.
