Patent

CA 2378618

Described are medical devices which are or can be used to form tubular medical devices, and related methods. Preferred devices include tubular grafts of biomaterial having lumen walls which present no seam edge that traverses the entire length of the lumen, illustratively including devices having lumen walls which have a discontinuous seam presenting multiple seam edges. Such a device may include a tubular structure formed by inserting a plurality of extensions (14) of a biomaterial sheet (12) through a plurality of corresponding apertures (16) of the sheet.

L'invention porte sur des dispositifs médicaux pouvant servir à former des dispositifs médicaux tubulaires et sur les procédés associés. Les dispositifs préférés consistent en greffons dont les parois de la lumière sont exemptes d'arêtes de couture sur la totalité de leur longueur. Ces articles sont illustrés par des dispositifs dont les parois de la lumière comportent une couture discontinue à plusieurs arrêtes. De tels dispositifs peuvent consister en une structure tubulaire formée par l'insertion d'une série d'extensions (14) d'une feuille d'un matériau biologique (12) dans une série correspondante de fentes (16) percées dans la feuille.
