URINARY DRAINAGE CATHETER

摘要

A urinary drainage catheter provides fluid communication between a distal end and a proximal end of the catheter and includes a retention mechanism for retaining the distal end of the catheter within a patient's bladder. The catheter has an outer sleeve comprising a distal portion and a proximal portion with a deformable zone therebetween, the deformable zone having a plurality of elongate slits extending at least partially in an axial direction along the outer sleeve between the distal portion and the proximal portion of the outer sleeve; and a compression mechanism for causing relative displacement of the distal portion and the proximal portion so as to open the slits by deformation in the deformable zone.
