Abstract: Bioresorbable polymeric tubes suitable for use in a stent have been produced by a using a die drawing technique, comprising: —deforming an orientable, thermoplastic polymer tubing (4) in the solid phase by drawing it over a mandrel (1) and/or through a die (3), where the mandrel (1) has a lead end and an exit end and the die (3) has an entry side and an exit side, wherein a drawing mechanism applies a drawing tension to the tubing (4) from the exit end of the mandrel (1) and/or the exit side of the die (3), said tension being insufficient to cause tensile failure of the tubing but sufficient to deform the tubing, thereby drawing the tubing over the mandrel (1) and/or through the die (3) in the solid phase to induce uniaxial or biaxial orientation of the polymer; and —collecting the deformed tubing from the exit end of the mandrel (1) and/or the exit side of the die (3).

Abstract: A tubular stent has first and second ends and a longitudinal axis therebetween. The tubular stent is formed from a network of struts which defines a cylindrical surface about the longitudinal axis, the struts delineating a plurality of cells within the network, there being rows of cells parallel to the longitudinal axis. At least one cell in each row is a nodal cell. There is an increase in the maximum length parallel to the longitudinal axis of cells from the nodal cell to a first distal cell in the row that is closer to the first or second end of the tubular stent. There is a second distal cell in the row which has a different maximum length parallel to the longitudinal axis from the nodal cell and the first distal cell. The network of struts comprises a plurality of circumferential rings. Each ring extends perpendicularly to the longitudinal axis and the rings are located adjacent to each other parallel to the longitudinal axis to define the cylindrical surface.

Abstract: A tubular stent (1) has first and second ends (2,3) and a longitudinal axis (4) therebetween. The tubular stent (1) is formed from a network of struts which defines a cylindrical surface about the longitudinal axis (4), the struts delineating a plurality of cells {23, 30, 31, 32, 33) within the network, there being rows of cells parallel to the longitudinal axis (4). At least one cell in each row is a nodal cell (23). There is an increase in the maximum length parallel to the longitudinal axis (4) of cells from the at least one nodal cell (23) to a first distal cell (30) in the row that is closer to the first or second end (2, 3) of the tubular stent (1). There is a second distal cell (31) in the row which has a different maximum length parallel to the longitudinal axis (4) from the nodal cell (23) and the first distal cell (30). The network of struts comprises a plurality of circumferential rings (6, 6?, 9, 9?, 13, 13?, 16, 16?, 17, 17?).
