摘要:
An endovascular assembly of a guidewire having two stoppers and a deformable element having a deformable basket/braid and two sliders sliding over the guide wire. The distance between the stoppers is smaller than the distance between the sliders so that when the stoppers each engages a slider, the deformable basket is thicker than its rest shape. In one embodiment, the distance between the stoppers may be altered to facilitate e.g. retrieval of the assembly.
摘要:
A fixator assembly comprising a fixator for fixing inside a blood vessel, a guide tube attached to the fixator and a pump for supplying a liquid to the blood vessel or from the blood vessel via the guide tube. Blood flow past the fixator is possible during pumping so that critical situations are avoided. A method of providing a liquid to a blood vessel using the assembly is also claimed. Sampling or liquid dosing thus may be performed during extended periods of time while performing this at a well-defined position in the blood vessel and potentially close to or at the desired position in the person.
摘要:
A fixator assembly comprising a fixator for fixing inside a blood vessel, the fixator being able to slide proximally along a guide wire. The assembly comprising means for preventing the fixator from moving distally of the preventing means. A tubular element for introduction into a blood vessel of a person, the tubular element comprising an end opening and a plurality of side openings as well as a transport wire extending from inside the tubular element and to the surroundings thereof through an individual side opening.
摘要:
An assembly of a retrieving element and a retrievable device of which one is a helical spring having an outer part of a winding which extends away from a main portion of the spring and thus is able to engage a thread of the other of the retrieving element and a retrievable device. The other of the retrieving element and a retrievable device may have an outer or an inner thread. The assembly may be used for retrieving devices temporarily positioned in a blood vessel of a person.
