Patent ID: 8652162

Claim:
A catheter assembly suitable for conducting and positioning a medical device in an organic vessel having a main cavity and at least one side branch said catheter assembly comprising: first and second guide wires; and a catheter comprising a tubular body, having a central lumen extending along said tubular body around a longitudinal axis (X), said central lumen having a cross-section such as to allow the passage of at least one medical device, wherein the tubular body distally comprises a radially expandable balloon that is configurable between a non-expanded state that defines a translation configuration of the tubular body and an expanded state that defines an anchorage configuration of the tubular body and wherein the tubular body comprises an inflation lumen for the introduction of a fluid suitable for causing the expansion and/or contraction of the balloon; and a mandrel slidably positioned inside said central lumen, said mandrel including a flexible distal end portion having a proximal extremity and a distal extremity and having one of a substantially elliptical, oval or semicircular cross-section, a proximal portion having an outer surface, facing the tubular body with a longitudinal groove, wherein said longitudinal groove defines with an inner wall of the tubular body a passage suitable for receiving said first guide wire in a sliding manner and wherein said longitudinal groove ends at said proximal extremity of said flexible distal end portion with a distal opening in the direction of the longitudinal axis (X), and an inner lumen suitable for receiving said second guide wire in a sliding manner that extends within said proximal portion and said flexible distal end portion, wherein a tip opening for accessing said inner lumen is disposed at said distal extremity of said flexible distal end portion.
