1. :
- A medical device having a proximal end for insertion into a body of a living being and an opposite distal end, the device comprising an elongated tube forming a conduit extending in an axial direction, the tube comprising a braided portion with crossed filaments which form a braiding angle with the axial direction, the braided portion being operable between a first configuration wherein it has a first size in a direction transverse to the axial direction and a second configuration wherein it has a second size in the direction transverse to the axial direction, the second size being larger than the first size.

Abstract
The invention provides a medical device such as a catheter for draining fluids from the body of a living being. The device has a braided portion with crossed filaments which form a braiding angle with a centre axis of the device. The braided portion can be expanded in a direction transverse to the centre axis e.g. in order to anchor the device in the body, e.g. to retain a urinary catheter in the bladder of a patient. The filaments form at least two different braiding angles which thereby facilitate an increased expansion or expansion into a specific shape of the expanded portion and thereby facilitates an improved anchoring of the device in the body.
