Abstract: A stretchable-diameter inserter, for hemodynamic studies and related operations, is characterized in that it comprises an inserter tube, a hemostatic valve designed for preventing blood from exiting the patient toward the operator, a side line including a faucet, adapted to be used for performing blood taking and infusion operations and two dilatators: a first dilatator having a smaller cross-section and a second dilatator having a larger cross-section.

Abstract: A variable diameter tube for use in a vessel inserter for performing hemodynamics researches and related operations comprises two coupled different-characteristic materials which are coupled to one another to provide a single stretchable tube assembly.

Abstract: A device for treatment of a blood vessel includes: a catheter (C) configured to be inserted in a blood vessel (V) to be treated; a selection member (S) associated with the catheter (C) to prevent a blood flow at least in a determined section (T) of the blood vessel (V); a self-perfusion lumen associated with the catheter (C) to provide a fluidic connection between a first portion (P1) of the blood vessel (V) upstream the determined section (T) and a second portion (P2) of the blood vessel (V) downstream the determined section (T); a treatment system (F) associated with the catheter (C) to make a fluid drug flow at least to the determined section (T).

Abstract: A plastics material variable diameter tubular structure for a biomedical use has a diameter which increases as the structure is subjected to an inner force, and returns to a starting diameter in a rest condition of the structure, the tubular structure being advantageously used for making a body of a vascular introducer device.
