Abstract: A method of treating the back pain of a patient which can include the steps of weighing the patient, selecting a firmness of a mattress based on the patient's weight, and disposing a three-dimensional fabric overlay over the mattress for use by the patient. To select the mattress, it can be determined if the weight of the patient corresponds to a value and if the weight is less than or equal to the value, a firm mattress is selected, and selecting a soft mattress if the weight is greater than the value. Further, the overlay can have a plurality air spaces provided between an upper layer, a lower layer and a plurality of monofilaments in the overlay. The plurality of air spaces can be allowed to partially collapse under the weight of the patient.

Abstract: A method for making a lightweight surgical mesh, having the steps of applying a first set of filaments in a first wale direction and forming a first series of loops at each of a plurality of courses. Applying a second set of filaments in the first wale direction and forming a second series of loops at a first adjacent wale to the first wale direction and a third series of loops at a second adjacent wale opposite the first adjacent wale along the plurality of courses. Further, applying a third set of filaments in the first wale direction so that the second series of loops are formed at the second adjacent wale and the third series of loops are formed at first adjacent wale along the plurality of courses. Additionally, applying a fourth set of filaments that interlace repeatedly with the first set of filaments along the first wale direction.

Abstract: Prosthesis to treat hernia, can include a single mesh sheet having biocompatible fibers. It has a flat portion, an unstiffened protuberance formed from the flat portion, and an opening in the flat portion formed by the protuberance having a first diameter. The protuberance includes a proximal portion closest to the flat portion having a proximal portion height, and a distal portion disposed farthest from the flat portion having a distal portion height, a second diameter, and an end of the distal portion is unstiffened. The proximal portion height is a distance from the flat portion to a beginning of the distal portion, and the distal portion height can be a distance from the flat portion to the end of the distal portion. The second diameter is greater than the first diameter, and a first ratio of the distal portion height to the proximal portion height is approximately 1.4 to 3.0.

Abstract: A prosthesis for the treatment of hernias and/or laparoceles via an intraperitoneal route, having a mesh of filaments of non-resorbable and biocompatible polymer material having interstices permitting tissue growth and a sheet of polymer material having barrier properties and low adhesion to sensitive organs and tissues. The sheet is superimposed upon and joined to the mesh so as to form a stratified structure. In particular, the sheet is joined to mesh through a plurality of filaments located alongside each other at a spacing of not more than 5 mm. Each filament has a plurality of attachment sites to the mesh which are not more than 15 mm apart, and each length of filament between two successive attachment sites projects from the surface of the mesh facing sheet and is fused to the sheet.

Abstract: A lightweight knitted surgical mesh which includes a first axis, a second axis perpendicular to the first axis, a third axis offset approximately 30° to 60° from the first axis, and a fourth axis perpendicular to the third axis. Further the mesh has a first weave running parallel to the first axis, a second weave running parallel to the second axis, a third weave running parallel to the third axis, and a fourth weave running parallel to the fourth axis. In an embodiment, the third axis is offset 45° from the first axis to form an isotropic mesh.

Abstract: A series of kits for an indirect and direct inguinal hernia operations for both male patient and a female patients. The kit for the male patient comprises two plugs and one mesh piece. The plugs and mesh are made from a polymer mesh and are pretreated so that they lay flat within the body after a hernia operation. These two plugs and mesh piece are sterilized and placed within a kit so that during an operation for hernia repair, a doctor has the necessary plugs precut and sterilized so that he can place these plugs within a patient's body. In this case, the plugs and mesh pieces have holes and slits formed to receive a spermatic cord. Since a female patient does not have a spermatic cord, the plug and mesh piece in this kit do not have holes or slits for a spermatic cord. There is also a third kit for large primary and recurrent groin hernias that cause weakening of the entire floor canal. This kit contains a flat rigid hernial plug and a preshaped mesh piece. The two pieces are attached in a two-mesh pair.
