Endovascular medical device with plurality of wires

A vascular medical device comprising:

• a catheter having a distal end, a distal end segment, a body portion having at least one lumen extending through the body portion in a longitudinal direction from a proximal end toward the distal end, which body portion is made of a multiple filament helically wound row of from four to eight wires of circular cross-section closely adjacent to each other, wherein said row of wires has a pitch angle in the range of 40° to 65°, the wires being provided with a low-friction sealing coating of elastic material on at least a radially outwardly facing surface, the sealing coating having a thickness at the middle of each of the wires of less than 0.1 mm, with the number of wires in the row diminishing in the distal direction and ones of the wires extending into the distal end segment are continuous from the distal end segment to the proximal end of the catheter.

A catheter system comprising:

• a catheter having a distal end, a body portion having at least one lumen with an inside surface extending through the body portion in a longitudinal direction from a proximal end toward the distal end, and at least one central member for coaxial advancement through said lumen, which body portion is made of a multiple filament helically wound row of wires, wherein said row of wires has a pitch angle in the range of 26° to 76°, and wherein said inside surface of said body portion is mainly undeformable by the central member.

A delivery system comprising:

• a delivery device with a distal end and a shaft portion with a lumen extending in a longitudinal direction from a proximal end and toward the distal end, a self-expandable prosthesis arranged in a receptacle at the distal end of the delivery device, and a pusher member arranged in the lumen of said delivery device to cause relative axial movement of the self-expandable prosthesis with respect to the delivery device, said shaft portion of said delivery device comprising a first helically wound multiple filament row of wires.

An embolization device introducer comprising:

• a delivery member having a proximal section, and a distal section with a connection means for detachably mounting of an embolization device, wherein the delivery member comprises a multiple filament helically wound row of four to eight closely adjacent wires extending from said distal section toward the proximal section of the delivery member, wherein said row of wires has a pitch angle in the range of 40° to 65°, the wires being provided with a low-friction sealing coating of elastic material on at least a radially outwardly facing surface, the sealing coating having a thickness at the middle of each of the wires of less than 0.1 mm.

An embolization device introducer comprising:

• a delivery member having a proximal section, and a distal section with a connection means for detachably mounting of an embolization device, wherein the delivery member comprises a multiple filament helically wound row of wires extending from said distal section toward the proximal section of the delivery member.
