FABRIC PROSTHESIS FOR REPAIRING A TISSUE WALL DEFECT IN PROXIMITY OF A TUBE-LIKE STRUCTURE

摘要

Implantable prostheses for repairing soft tissue defects near an anatomical tube and methods for their manufacture are described. Exemplary prostheses may be implanted at a soft tissue repair site, for example, in treating an inguinal hernia. An implantable prosthesis may include a patch made up of two co-knit fabric layers, and a passageway for receiving an anatomical cord extending through the fabric layers. The passageway is configured through the first fabric layer so as to minimize the prospects of the cord-like structure contacting the portion of the second fabric layer defining the passageway therethrough. The passageway through the first fabric layer may include a barrier.

主权项

1. An implantable prosthesis for repairing a tissue wall defect near a tubular structure, comprising:
a first fabric layer; a second fabric layer having a medial edge, a lateral edge, a superior edge and an inferior edge, the second fabric layer adjacent the first fabric layer and including a body portion constructed and arranged to cover and to repair an inguinal hernia defect; a passageway extending through the first fabric layer and through the second fabric layer and adapted to receive a tubular structure, a cross-sectional area of the passageway extending through the first fabric layer being smaller than a cross-sectional area of the passageway extending through the second fabric layer, wherein a region of the second fabric layer located on a medial side of the passageway is continuous between the superior edge and the inferior edge of the second fabric layer along a line extending tangent to a medial edge of the passageway; wherein a portion of the first fabric layer defines the passageway that extends through the first fabric layer, the portion including a barrier.
