First Claim
Patent Images
1. A medical device, comprising:
- an elongate inner member having a proximal section and a distal section;
an elongated metallic tubular member disposed about the inner member, the tubular member including a first section, a tapered section, and a slotted section having a plurality of slots defined therein, wherein the tapered section is disposed between the first section and the slotted section; and
wherein the elongated metallic tubular member includes a length and defines a lumen extending therethrough, the lumen having an inner diameter, and wherein the inner diameter of the lumen remains substantially constant along the length of the tubular member.
