Abstract:
1. A medical catheter comprising: an outer tubular member having a proximal end, a distal end and a lumen extending therethrough, the outer tubular member including: an inner tubular member having a proximal end and a distal end, the inner tubular member disposed within the lumen of the outer tubular member, an annular lumen defined between the inner tubular member and the outer tubular member; and a tubular transition member having a proximal end, a distal end and an annular wall extending between the proximal end and the distal end, the transition member positioned within the annular lumen defined between the inner tubular member and the outer tubular member, wherein the transition member bridges the junction of the outer tubular member such that the proximal end of the transition member is located proximal of the junction of the outer tubular member and the distal end of the transition member is located distal of the junction of the outer tubular member; the transition member including at least one cut extending through the annular wall of the transition member providing the transition member with a degree of flexibility.
