         17 . The method of  claim 3 , in which the mixer portion comprises an hourglass-shaped tubular portion. 
     
     
         18 . The method of  claim 3 , in which the mixer portion comprises a shape of repeating hourglasses. 
     
     
         19 . The method of  claim 3 , in which the mixer portion comprises a first portion and a second portion, in which a diameter of the first portion is greater than a diameter of the second portion. 
     
     
         20 . The method of  claim 3 , in which the mixer portion comprises a first portion, a second portion, and a third portion, in which a diameter of the first portion is greater than a diameter of the second portion and the diameter of the second portion is less than a diameter of the third portion. 
     
     
         21 . The method of  claim 3 , in which the mixer portion comprises a tubular portion having a circular cross section. 
     
     
         22 . The method of  claim 3 , in which the mixer portion comprises a tubular portion having a cross section shape that varies along a length of the portion. 
     
     
         23 . The method of  claim 3 , in which the mixer portion comprises a first portion and a second portion, in which a width of the first portion is greater than a width of the second portion. 
     
     
         24 . The method of  claim 3 , in which the mixer portion comprises a first portion, a second portion, and a third portion, in which a width of the first portion is greater than a width of the second portion and the width of the second portion is less than a width of the third portion. 
     
     
         25 . The method of  claim 3 , in which the mixer portion comprises a first portion and a second portion, in which a cross sectional area of the first portion is greater than a cross sectional area of the second portion. 
     
     
         26 . The method of  claim 3 , in which the mixer portion comprises a first portion, a second portion, and a third portion, in which a cross sectional area of the first portion is greater than a cross sectional area of the second portion and the cross sectional area of the second portion is less than a cross sectional area of the third portion. 
     
     
         27 . The method of  claim 3 , in which the mixer comprises a first portion, a second portion, a third portion, and a fourth portion in which a cross sectional area of the first portion is greater than a cross sectional area of the second portion, the cross sectional area of the second portion is less than a cross sectional area of the third portion, and the cross sectional area of the third portion is greater than a cross sectional area of the fourth portion. 
     
     
         28 . The method of  claim 3 , in which the clotting agent is thrombin. 
     
     
         29 . The method of  claim 3 , in which the mixer portion comprises a portion having a tortuous shape.
