Übersetzung für "Coronary stent" in Deutsch

This becomes visible on the example of a coronary stent.

A radiation source can also be placed in blood vessels (intravascular brachytherapy) for the treatment of coronary in-stent restenosis.

The present invention relates to a coronary stent comprising a tubular, flexbile body whose wall has a web structure, said web structure comprising a plurality of adjacent cells which are defined by webs and which are each connected via joint webs to adjacent cells.

BACKGROUND OF THE INVENTION The invention relates to a stent, particularly a coronary stent, as an intraluminal expansion element, and a method of manufacturing the stent.

The coronary stent 1 of the inventive structure is very flexible in the non-expanded state both in the longitudinal direction and in the transverse direction.

The invention concerns a stent, and, in particular a coronary stent for implantation in the region of vessel branching& having a tubular casing with a proximal end and a distal end.

The invention concerns a stent, in particular a coronary stent, comprising at least two tubular portions which are arranged adjacently in the longitudinal direction of the stent and which comprise a plurality of interconnected, substantially cell-shaped elements which have an orientation and are connected together in the longitudinal direction of the stent by way of at least one first connecting means, wherein the elements are of such an arrangement and/or configuration that the ends of the elements which are in the longitudinal direction of the stent define an edge contour extending around the stent in a wave-like configuration in the peripheral direction thereof.

The invention concerns a stent, in particular a coronary stent, comprising a tubular portion, wherein openings are provided in the tubular portion.

In only 28.1% of patients with coronary stents, the stent type could be clearly classified during anesthesiological pre-assessment (for example, "bare metal stents" or "drug-eluting stents").

In this case, any medical implant deemed suitable by a person skilled in the art could be used, for example, an implant for recording physiological parameters, a cardiac pacemaker, a defibrillator, a cardioverter, a cerebral pacemaker, a neural stimulator, a renal pacemaker, a duodenal pacemaker, a cardiac implant, artificial heart valves, a cochlear implant, a retinal implant, a dental implant, an implant for joint replacement, a vascular prosthesis, or particularly advantageously a stent, such as a coronary stent, a renal artery stent, or a urethral stent, and a drug delivery system.

The invention concerns a stent, in particular a coronary stent, comprising at least one first tubular portion and at least one second tubular portion, wherein the first and second tubular portions are connected together by at least one first connecting means.

The production of an implant according to the invention is presented in the following using the example of a biodegradable vascular support in the form of a coronary stent.

Unpretreated stent grafts (“JOSTENT Coronary Stent Graft”) comprising a sandwich construction of two stainless steel stents with a PTFE membrane are mounted on holders.

In addition to these requirements, the original mechanical functions of a coronary stent should be retained, e.g., dilatability, low recoil, stability over a desired period of time (in the case of degradable stents comprising magnesium and its alloys, for example) and flexibility.

It can be transposed to particular advantage however if the implant is a stent, in particular a coronary stent.

The present invention concerns a stent, in particular a coronary stent, for expansion from a first condition into an expanded second condition in which it holds a vessel in an expanded state, comprising a tubular body whose peripheral surface is formed by a number of support portions which extend in the longitudinal direction of the stent and comprise bar elements which are connected by way of connecting bars.

During the implantation of the coronary stent, the balloon may cause fissures in the adjacent vessel wall (peristent dissection).

In fact only the catheter coatings disclosed in WO 02/076509 A and WO 2004/028582 A led to effective products which reduce the extent and frequency of restenosis following vascular dilatation (Scheller B, Hehrlein C, Bocksch W, Rutsch W, Haghi D, Dietz U, Bohm M, Speck U. Treatment of Coronary In-stent Restenosis with a Paclitaxel-coated Balloon Catheter.

Patients between 18 and 75 years were included into the study, if they had a first acute ST-elevation myocardial infarction that was acutely treated by a coronary stent with GPIIb/IIIa blocking.

In that case the implant can be a joint or bone prosthesis, a dental implant or in particular a coronary vessel support coated with a peptide, for example BMP-2 (a so-called coronary stent, length about 10 mm) to therapeutically prevent or alleviate the later complication of restenosis caused by proliferation of smooth vessel muscle cells, in order thereby to promote healing and compatibility.

The drug-carrier combination has already demonstrated early clinical efficacy in the recently presented first-in-man study PEPPER, investigating BIOTRONIK’s Pantera Lux DEB in coronary in-stent restenosis.
