US 2006/0041244 A1 · Hemocirculatory catheter and method of use thereof

Abstract

The catheter to be inserted into a vein (4) of the blood circulation, comprising a conduit (7) with at least one expandable anchoring element (13) at its distal end (8) for anchoring in the vein wall, and a tube-shaped jacket (sheet 14) that is pushed onto the conduit (7) and can be at least partially withdrawn in a proximal direction once the conduit (7) has been inserted into the vein (4), thereby releasing the at least one anchoring element (13), so that it can expand. The conduit (7) comprises a bottleneck (17) at the distal end of its lumen (8) and the catheter comprises a tube-shaped element (pusher 15) to be pushed onto a guiding wire (11). The front end of said element bearing against the bottleneck.

Dependent claims

A catheter to be inserted into a vein of blood circulation for myocardial revascularization by partial arterialization of a coronary sinus, comprising:

a conduit having a lumen and with at least one expandable anchoring element at its distal end for anchoring in a vessel wall, the conduit comprising a bottleneck at the distal end of its lumen;
a tube-shaped jacket that is pushed onto the conduit and can be at least partially retracted in a proximal direction once the conduit has been inserted into the vessel, thereby releasing the at least one anchoring element, so that it can expand;
and
a pusher to be pushed onto a guiding wire, a front end of said pusher bearing against the bottleneck.

1 more element

A method of myocardial revascularization by arterialization comprising:

accessing a coronary sinus having a first end, a second end, and an intermediate portion having a veinous inlet, said second end fluidly connected to a vein having a lumen defined in part by a wall;
inserting a distal end of a conduit having a proximal end, a central lumen, and a distal end through the coronary sinus into a portion of the coronary sinus or into a portion of the vein;
engaging the distal end of the conduit with the coronary sinus or the vein;
connecting the proximal end of the conduit to a central arterial blood supply;
and
supplying a substantially continuous blood flow from the central arterial blood supply through the central lumen of the conduit into the portion of the coronary sinus or the vein.
