In one exemplary embodiment, an endovascular device may include a hollow shaft having a proximal end and a distal end, and sized for insertion into a blood vessel. The endovascular device may also include a control line having a proximal end and a distal end, and extending through the hollow shaft. The endovascular device may also include an actuatable working element located proximate the distal end of the hollow shaft, and configured to receive an actuation force transmitted via the distal end of the control line. The endovascular device may further include an actuator configured to exert the actuation force on the proximal end of the control line, to thereby cause relative movement between the control line and the hollow shaft and to actuate the working element. The hollow shaft may also include a cable formed of a plurality of wound wires and including a proximal segment, at least one transition segment, and a distal segment. The proximal segment, at least one transition segment, and distal segment may include different numbers of wires.

Provided are a resin composition and a soldering flux. The resin composition includes at least one acid and rosin. The acid is selected from a dimer acid which is a reaction product of oleic acid and linoleic acid, a trimer acid which is a reaction product of oleic acid and linoleic acid, a hydrogenated dimer acid obtained by hydrogenating a dimer acid which is a reaction product of oleic acid and linoleic acid, and a hydrogenated trimer acid obtained by hydrogenating a trimer acid which is a reaction product of oleic acid and linoleic acid. A weight ratio of the at least one acid to the rosin is 0.15 or more and 1.00 or less based on the weight of the rosin. The soldering flux is obtained by diluting the resin composition with a solvent.

Disclosed is a pressure-sensitive adhesive composition which exhibits good adhesive forces, in particular on polar adhesive substrates, and good shear strength, and a significant proportion of which can be produced from bio-based raw materials. The pressure-sensitive adhesive composition comprises: at least one copolymer which can be traced to a monomer composition comprising a) 45-75 wt. % of at least one monomer selected from i-amyl acrylate, n-heptyl acrylate, and 2-octyl acrylate, b) 24-50 wt. % of at least one alkyl (meth)acrylate, the alcohol component of which has 1 to 4 carbon atoms, and c) 0.5 to 10 wt. % of acrylic acid; and at least one adhesive force-enhancing resin. Also disclosed is an adhesive tape comprising a carrier material and the pressure-sensitive adhesive composition; and the use of the pressure-sensitive adhesive composition or the adhesive tape to produce adhesive bonds in electronic, optical and/or precision mechanical devices.
