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 a proximal direction and leading to the guidewire lumen. A proximal section of the guidewire lumen is straight.
Claims25
A catheter comprising
- a body comprising a distal portion and a proximal portion, wherein the distal portion defines a guidewire lumen and includes a guidewire exit port being open in a proximal direction and leading to the guidewire lumen, and wherein a proximal section of the guidewire lumen is straight.
A catheter comprising
- a body including a first portion and a second portion and defining an inner lumen extending through the first and second portions, the first portion extending proximally from a proximal end of the second portion, wherein the second portion comprises an opening on the proximal end, the opening is facing the proximal direction and leading to a guidewire lumen of the second portion, and at least a section of the guidewire lumen is straight.
A catheter comprising
- a first shaft comprising a skived proximal portion and defining a first lumen, the skived proximal portion including a guidewire exit port being open the proximal direction;
- and
- a second shaft comprising a skived distal portion and defining a second lumen, the skived distal portion being coupled to the skived proximal portion such that the first lumen and the second lumen form a continuous lumen.
