摘要： A method for the preparation of a regenerated silk fibroin solution comprises the steps of: treating silk or silk cocoons with an ionic reagent comprising an aqueous solution of monovalent cations and monovalent anions, the cations and anions having ionic radii of at least 1.05 Angstroms and a Jones-Dole B coefficient of between −0.001 and −0.05 at 25° C.; and subsequently degumming the treated silk or silk cocoons; or alternatively, degumming silk or silk cocoons; and subsequently treating the degummed silk or silk cocoons with an ionic reagent comprising an aqueous solution of monovalent cations and monovalent anions, the cations and anions having ionic radii of at least 1.05 Angstroms and a Jones-Dole B coefficient of between −0.001 and −0.05 at 25° C. The invention also extends to fibroin solution, a fibroin material and an implant useful for cartilage repair.

摘要： An apparatus and method for forming liquid spinning solution into a solid formed product whereby the solution is passed through at least one tubular passage (17) having walls formed at least partly of semipermeable and/or porous material. The semipermeable and/or porous material allows parameters, such as the concentration of hydrogen ions, water, salts and low molecular weight, of the liquid spinning solution to be altered as the spinning solution passes through the tubular passage(s).

摘要： A medical device comprises a tubular body having a lumen and a long axis; and a plurality of silk elements laid substantially parallel along the long axis of the lumen of the tubular body. A method of manufacturing the medical device comprises forming the tubular body and introducing the silk elements into the lumen of the tubular body so as to lie substantially parallel along the long axis of the lumen of the tubular body. The device can be used in a method for the regeneration of nerve cells comprising the implantation of a medical device at a site for regeneration of nerves.
