Bioabsorbable Polymeric Medical Device

Abstract

In embodiments there is described a cardiovascular tube-shaped lockable and expandable bioabsorbable scaffold having a low immunogenicity manufactured from a crystallizable bioabsorbable polymer composition or blend.

1 . A bioabsorbable scaffold circumferential about a longitudinal axis so as to form a tube comprising:
 (a) a plurality of first meandering elements extending around the circumference of the scaffold;   (b) a plurality of second meandering elements intercalated between adjacent first meandering elements.   
   
   
       2 . The bioabsorbable scaffold of  claim 1  wherein the first meandering element forms a sinusoidal shape. 
   
   
       3 . The bioabsorbable scaffold of  claim 2  wherein the second meandering element forms a hoop when the scaffold is fully deployed. 
   
   
       4 . The bioabsorbable scaffold of  claim 1  wherein the first meandering element forms a sinusoidal pattern when the scaffold is deployed. 
   
   
       5 . The bioabsorbable scaffold of  claim 4  wherein the scaffold is fully deployed. 
   
   
       6 . The bioabsorbable scaffold of  claim 5  wherein the second meandering element forms a hoop. 
   
   
       7 . The bioabsorbable scaffold of  claim 1  further comprising a locking means attached to at least one first meandering element. 
   
   
       8 . The bioabsorbable scaffold of  claim 1  further comprising a key-in-lock design element attached to at least one first meandering element. 
   
   
       9 . The bioabsorbable scaffold of  claim 1  wherein the second meandering element is made from a material which crystallizes when the tube is in its expanded state. 
   
   
       10 . The bioabsorbable scaffold of  claim 1  further comprising a hook design element attached to at least one first meandering element. 
   
   
       11 . The bioabsorbable scaffold of  claim 1  wherein the plurality of first meandering elements are interconnected to the second meandering elements. 
   
   
       12 . A stent comprising:
 a plurality of biodegradable, circumferential band; and   a plurality of biodegradable interconnection structures spanning between each pair of circumferential bands and connected to multiple points on each.   
   
   
       13 . The stent of  claim 12 , wherein the stent is in an expanded configuration. 
   
   
       14 . The stent of  claim 12 , wherein the stent is in an unexpanded configuration. 
   
   
       15 . The stent of  claim 12 , further comprising a locking means connected to the circumferential bands. 
   
   
       16 . The stent of  claim 12 , further comprising a key-in-lock design element attached to at least one circumferential band.
