The present invention relates to a method of thermal treatment of thermally responsive material wherein areas in or on the material to be thermally treated are defined and thermal energy is inputted on or into the defined areas in order to change/influence the material characteristics. The present invention further relates to medical devices or parts thereof manufactured at least in part from thermally responsive material by a process comprising at least one step of thermal treatment of this thermally responsive material.
Method of producing a balloon 1 of a balloon catheter comprising the following method steps: - preparing a balloon body 2 with a proximal sleeve 5 and a distal sleeve 6, with transitional sections 3, 4 extending between the balloon body 2 and the respective sleeve 5, 6; - creating folds 7 in at least the distal sleeve 6; and - fixing at least a distal section of the folds 7 of the distal sleeve 6.
Catheter 1, in particular PTCA catheter, comprising an outer tube 2; an inner guide wire tube 3 within the outer tube 2, said inner guide wire tube 3 having a tip 4; a first and a second marker 5, 6 fixed to the guide wire tube 3 at a fixed distance b to one another; and a balloon 7 having two sleeves 8, 9 fixed to the outer tube 2 and the inner tube 3, respectively, wherein that the distance b between the markers 5, 6 is set to be at least approximately equal to the distance a between the tip 4 and the marker 5 neighbouring the tip 4.
Surgical and medical apparatus and instruments namely stents; catheters, balloon-catheters, diagnostic catheters, heart support systems; medical implants; suture materials; connections for conorary bypasses; guidewires for catheters.
