TEXTILES, IMPLANTABLE MEDICAL DEVICES USING SUCH TEXTILES, AND PROCESSES FOR MAKING THE SAME

A 3-D honeycomb textile can include a textured yarn. The textile can exhibit a heat-shrinkage rate from about 10% to about 60%. The textile can be configured to reversibly change its dimensions under application of stress. Prosthetic valves can have the disclosed textiles as a sealing member. Additi...

Beschreibung
Zusammenfassung:	A 3-D honeycomb textile can include a textured yarn. The textile can exhibit a heat-shrinkage rate from about 10% to about 60%. The textile can be configured to reversibly change its dimensions under application of stress. Prosthetic valves can have the disclosed textiles as a sealing member. Additionally, prosthetic valves can the disclosed textiles as cushion materials. In addition, methods of making the disclosed textiles and prosthetic valves are described. Un textile en nid d'abeilles en trois dimensions peut comprendre un fil texturé. Le textile peut présenter un taux de retrait thermique d'environ 10 % à environ 60 %. Le textile peut être conçu pour changer de manière réversible ses dimensions sous l'application d'une contrainte. Des valves prothétiques peuvent présenter les textiles selon l'invention en tant qu'élément d'étanchéité. De plus, des valves prothétiques peuvent utiliser les textiles selon l'invention en tant que matériaux d'amortissement. En outre, l'invention concerne des procédés de fabrication des textiles et des valves prothétiques de l'invention.
