INTRAVASCULAR CATHETER CONTAINING REINFORCING MICROTAPE Russian patent published in 2013 - IPC A61M25/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine and may be used for diagnostic, including intravascular, procedures. What is used is a catheter comprising a longitudinally pre-oriented tubular carrier, a reinforcement wound on the carrier either in the form of braiding, or spirally, surrounding and being in contact with the carrier, and a tubular coating layer surrounding and pressing the reinforcement to the carrier substrate, thereby keeping it wound on the carrier. This reinforcement represents a micro-tape max. 0.5 mm wide and having a fibre layer having a cross-section aspect ratio (width/height) from 2 to 20. The fibres are bonded by cured or setting solid resin or wax making 2-40 wt % of the micro-tape. The fibres represent aramid or high modulus polyethylene, or polyetheretherketone, or polyester-polyarylate.

EFFECT: invention enables guiding the catheter for the purpose of the intravascular procedures due to generating a good torque transmission and an adequate carrier structure to minimise bendings that is caused by rigidity comparable to the metal reinforcement; that is combined with a possibility to scan a patient with the catheter introduced due to microwave inactivity of the catheter to scan the patient using magnetic resonance tomography.
