Storable Molded Body, Implant and Catheter System

Abstract

A storable molded body is made of treated bacterial cellulose. The treated bacterial cellulose is dry and has a swelling capacity that is greater than untreated bacterial cellulose of the same type. The swelling capacity of the treated bacterial cellulose can be between about 103% and 154% greater than the non-treated bacterial cellulose. The bacterial cellulose can be from Gluconacetobacter xylinus. An implant includes or consists of the molded body of treated bacterial cellulose.

1 . A storable molded body made of treated bacterial cellulose, wherein the treated bacterial cellulose is dry and has a swelling capacity that is greater than untreated bacterial cellulose of the same type. 
     
     
         2 . The storable molded body according to  claim 1 , wherein the swelling capacity of the treated bacterial cellulose is between about 103% and 154% greater than the non-treated bacterial cellulose. 
     
     
         3 . The storable molded body according to  claim 1 , wherein the bacterial cellulose is from  Gluconacetobacter xylinus.    
     
     
         4 . The storable molded body according to  claim 1 , comprising a layer having a thickness in the range of 2 to 10 mm 
     
     
         5 . An implant comprising, entirely or in parts, the molded body according to  claim 1 . 
     
     
         6 . The implant according to  claim 5 , wherein the molded body is an implant shell. 
     
     
         7 . The implant according to  claim 6 , wherein the implant is a cardiac pacemaker or a defibrillator which is stored in the implant shell. 
     
     
         8 . The implant according to  claim 7 , wherein the implant shell is a separate pocket for accommodating electrode cables. 
     
     
         9 . The implant according to  claim 5 , wherein the molded body is a heart valve leaflet and/or a sealing shell between heart valve leaflets of a heart valve prosthesis. 
     
     
         10 . The implant according to  claim 9 , wherein an outer side of a stent base body of the heart valve prosthesis comprises barbs. 
     
     
         11 . The implant according to  claim 5 , wherein the molded body is an outer shell and/or inner shell of a stent graft made of the implant material. 
     
     
         12 . The implant according to  claim 11 , wherein the inner or outer shell comprises annular sections, which are disposed on the axial ends of the stent graft and exhibit a greater swelling capacity than do sections of the shells located between the two ends. 
     
     
         13 . The implant according to  claim 5 , wherein the molded body is a coating of a stent. 
     
     
         14 . The implant according to  claim 5 , wherein the molded body is a vascular path, an occluder, or an artificial tendon. 
     
     
         15 . The implant according to  claim 5 , wherein the molded body is a skirt for a heart valve stent, and the skirt has a thickness of 0.05 to 0.2 mm and a swelling ratio of at least 1:10. 
     
     
         16 . The implant according to  claim 15 , wherein the skirt comprises materials other than the bacterial cellulose. 
     
     
         17 . The implant according to  claim 15 , wherein the skirt consists of the bacterial cellulose. 
     
     
         18 . The implant according to  claim 5 , comprising a skirt for a heart valve stent, the skirt being disposed on the luminal side of a stent base body, and comprising at least one molded body of the bacterial cellulose sewn in between struts of the stent and the skirt. 
     
     
         19 . The implant according to  claim 18 , comprising a plurality of the molded bodies of the bacterial cellulose formed as an annular ring around the stent base body. 
     
     
         20 . A catheter system for the insertion of an implant according to  claim 5 , wherein the implant is mounted in the dried state on the catheter.
