Abstract
Abstract A ''stent'' (6) for use in conjunction with a balloon type catheter (2), in order to shore-up tissue (A) which has been damaged by use of the balloon type catheter (2), is characterised in that it comprises a coil-like spring member which is contained in a substantially linear stressed condition within the catheter (2) for transport to the diseased area (A) and which when released from the catheter (2) adopts a coiled configuration (6b) to hold the damaged tissue (A) in place whilst at the same time allowing blood flow.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
120 words
A catheter for flattening the interior wall of at artery or ' other organ includes the following combination of features: a) a balloon catheter or simple catheter tube; b) a "stent" contained within a) in a stressed
collapsed condition, the tube a) and "stent"
being movable axially with respect to one another
to progressively bring the "stent" outside the
tube, the "stent" then being radially
expandable;
characterised in that the "stent" comprises an
element which in its contracted state is
substantially linear to fit in the catheter tube
but which when free of the catheter tube adopts
an expanded hollow configuration whereby it can
press against the interior surface of an artery
but still allow blood flow through the artery.
Claim 2
Dependent Claim
