<p>The implant (10) consists of a flexible and biocompatible tube (20) with distal (24) and proximal ends, and incorporates one or more components (30,50) for absorbing axial stresses, so that the proximal end of the implant remains in position once implanted. The distal end of the implant is fitted, for example, with a blood filter (40). The stress-absorbing component is in the form of a bellows element or spiral spring.</p> |
