    摘要: Provided are therapeutic implants comprising renal tissue encapsulated within a polymer bead. Also disclosed are methods for treating a disease state in a subject comprising implanting within said subject a therapeutic implant comprising renal tissue encapsulated within a polymer bead. Also provided are methods for making a therapeutic implant comprising: providing renal tissue; mixing the renal tissue with a solution comprising a polymer, thereby forming a tissue-polymer suspension; extruding the tissue-polymer suspension into an bead-forming solution, thereby forming a therapeutic implant comprising beads of said polymer within which the renal tissue is encapsulated.

    摘要: An expandable, implantable medical device, such as an intraluminal stent (10) fabricated from polymeric materials, includes a plurality of elongated struts (16) in consecutive series and alternating stress concentration junctions (18) interconnecting ends of adjacent struts (16). When the stent (10) is in an expanded condition, the adjacent struts (16) form expanded substantial V-shapes and stresses are concentrated within the junctions (18). The junctions (18) define pivot points (P) for the respective attached, adjacent struts (16). Each of the pivot points (P) is located substantially on a line bisecting the V-shapes formed by the struts (16), when the stent (10) is expanded.
