Abstract
The invention relates to a delivery system for delivering a stent (S) into a body vessel of a patient, comprising a flexible catheter tube () having a proximal and a distal end for delivering the stent (S) to a predetermined location in the body vessel and a catheter tip () having a longitudinal direction, which is disposed at the distal end of the catheter tube (). The catheter tip () has a stent chamber () to receive the stent (). The catheter tip has a first pressure chamber (). In the catheter tube () a first fluid channel () extends from the proximal end to the first pressure chamber () of the catheter tip (). The volume of the first pressure chamber () can be enlarged by delivering a first fluid from the first fluid channel () to the first pressure chamber (), such that the stent (S) is released from the stent chamber () at the predetermined location in the body vessel. According to the invention the catheter tip () has a second pressure chamber (), wherein in the catheter tube () a second fluid channel () extends from the proximal end to the second pressure chamber () and wherein the volume of the second pressure chamber () can be enlarged by delivering a second fluid from the second fluid channel () to the second pressure chamber (), such that a partially released stent (S) can be returned from the predetermined location in the body vessel into the stent chamber (). This delivery system according to the invention makes it possible to release a stent (S) at a well-defined location and also to surround same again relatively atraumatically and to reposition same in situ.
