Abstract
Rapidly inserted central catheters (“RICC”), and methods thereof. A RICC can include a catheter tube including a first section in a distal-end portion of the catheter tube, a second section in the distal-end portion of the catheter tube proximal of the first section, and a junction between the first and second sections of the catheter tube. The first section of the catheter tube can be formed of a first material having a first durometer. The second section of the catheter tube can be formed of a second material having a second durometer less than the first durometer. The first and second sections of the catheter tube can have a column strength sufficient to prevent buckling of the catheter tube when inserted into an insertion site and advanced through a vasculature of a patient.
Claims24
A rapidly inserted central catheter (“RICC”), comprising:
- a first section of a catheter tube consisting of a first material having a first durometer, the first section in a distal-end portion of the catheter tube;
- a second section of the catheter tube consisting of a second material having a second durometer less than the first durometer, the second section in the distal-end portion of the catheter tube proximal of the first section, the first section and the second section of the catheter tube having a column strength sufficient to prevent buckling of the catheter tube when inserted into an insertion site and advanced through a vasculature of a patient;
- and
- a junction as a third section of the catheter tube including a third material having a third durometer between the first durometer and the second durometer, the junction located between the first section and the second section of the catheter tube and the junction including a tapered distal-end portion, the first section of the catheter tube including a flared proximal-end portion, and the tapered distal-end portion of the junction sitting within the flared proximal-end portion of the first section of the catheter tube.
A method of making a rapidly inserted central catheter (“RICC”), comprising:
- obtaining a first section of a catheter tube consisting of a first material having a first durometer, a second section of the catheter tube consisting of a second material having a second durometer, and a third section of the catheter tube including a third material having a third durometer between the first durometer and the second durometer;
- flaring a proximal-end portion of the first section of the catheter tube to form a flared proximal-end portion of the first section of the catheter tube;
- inserting a tapered distal-end portion of the third section of the catheter tube into the flared proximal-end portion of the first section of the catheter tube;
- abutting a distal-end portion of the second section of the catheter tube and the proximal-end portion of the third section of the catheter tube;
- and
- welding the first, second, and third sections of the catheter tube together to form a junction of the third material between the first section and the second section of the catheter tube.
