Abstract
The invention consists of a surface structure for a friction or sliding surface of a catheter (10) or guide wire (12) characterised by a plurality of recesses (18) distributed on the surface for accommodating a friction-reducing fluid and by sliding surfaces (20) between the recesses (18).
Claims11
A surface structure for a friction or sliding surface of a catheter (10) or guide wire (12) having a longitudinal and a peripheral direction, characterised by a plurality of recesses (18) distributed on the surface for accommodating a fluid contributing to a reduction in friction and by at least one continuous sliding surface (20) between the recesses (18), wherein the recesses are delimited in respect of their dimensions on the catheter surface both in the longitudinal direction and also in the peripheral direction by the sliding surface (20).
