1. A medical instrument comprising:
- an elastic tubular portion formed as a weaving portion; and
an actuating element arranged so that by its displacement it acts on said tubular portion so that said tubular portion assumes a first position in which it is expanded radially to assume a globe shape, and a second position in which it is reduced radially to assume a substantially cylindrical shape with a diameter substantially smaller than a diameter of said globe shape, said tube having a proximal end, a distal end, and elastic sections connecting said ends with one another, said actuating element having a distal end connected with said distal end of said tube so as to displace a distal end of said tube relative to said proximal end and therefore to expand said elastic sections and to straighten said elastic sections correspondingly.

Abstract
A medical instrument has an elastic tubular portion formed as a weaving portion, and an actuating element arranged so that by its displacement it acts on the tubular portion so that the tubular portion assumes one position in which it is expanded radially to assume a globe shape, and another position in which it is reduced radially to assume a substantially cylindrical shape with a diameter substantially smaller than a diameter of the globe shape.
