Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
139 words
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.
Claim 2
Dependent Claim
139 words
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.
Claim 3
Dependent Claim
19 words
A medical instrument as defined in claim 1, wherein said tubular portion is formed as a wire weaving portion.
Claim 4
Dependent Claim
18 words
A medical instrument as defined in claim 1, wherein said tubular portion is formed of a wire mesh.
Claim 5
Dependent Claim
18 words
A medical instrument as defined in claim 1, wherein said actuating element is formed as an elongated wire.
Claim 6
Dependent Claim
25 words
A medical instrument as defined in claim 1; and further comprising a tube associated with said tubular portion, said actuating element extending through said tube.
Claim 7
Dependent Claim
32 words
A medical instrument as defined in claim 1, wherein said elastic sections are formed as separate strips spaced from one another in a peripheral direction and separated from one another by slots.
Claim 8
Dependent Claim
29 words
A medical instrument as defined in claim 6, wherein said tubular element has opposite axial ends connected with said proximal portion and said distal portion of said tube correspondingly.
Claim 9
Dependent Claim
68 words
A medical instrument as defined in claim 1; and further comprising a tube, said actuating element extending through said tube and being connected with said tubular portion so as to pull said tubular portion into an interior of said tube so that said tubular portion assumes said second position or to withdraw said tubular portion outwardly beyond said tube so that said tubular portion assumes said first position.
Claim 10
Dependent Claim
33 words
A medical instrument as defined in claim 8, wherein said tubular portion has a distal end provided with a hollow cylinder, said actuating member extending through said hollow cylinder at said distal end.
Claim 11
Dependent Claim
29 words
A medical instrument as defined in claim 9; and further comprising a handle, said actuating element having a proximal end connected with said handle outside of said tubular portion.
Claim 12
Dependent Claim
27 words
A medical instrument as defined in claim 1; and further comprising an inlet for supplying a medium selected from the group consisting of liquid, air and contrast.
