Abstract
The present invention generally relates to a rapid exchange configuration that reduces the profile of a catheter riding on a guidewire and minimizes guidewire resistance. According to certain embodiments, a body of the catheter includes a distal portion and a proximal portion. The distal portion defines a guidewire lumen and includes a guidewire exit port being open in an proximal direction and leading to the guidewire lumen. A proximal section of the guidewire lumen is straight.
Claims14
An intraluminal catheter, comprising:
- a catheter body configured to be positioned within a body lumen of a patient,
- wherein the catheter body comprises a proximal portion, a distal portion, a joint between the proximal portion and the distal portion, a longitudinal direction, and a lateral direction extending between a first side and an opposite second side,
- wherein the proximal portion comprises a first material,
- wherein the distal portion comprises a different second material and a guidewire lumen,
- wherein the joint comprises:
- a transition between the first material and the second material, and
- a plurality of segments extending between a first joint location on the first side and a second joint location on the second side,
- wherein the plurality of segments comprises a first segment extending in the longitudinal direction,
- wherein the first joint location and the second joint location are spaced from one another in the longitudinal direction such that:
- the transition on the first side of the catheter body and the transition on the second side of the catheter body are spaced from one another in the longitudinal direction, and
- the transition extends in the lateral direction along the first segment, and
- wherein an opening of the guidewire lumen is co-located in the longitudinal direction with the transition at the second joint location.
