Abstract
Catheters are disclosed that are configured for insertion into the vasculature connected to the prostate gland of a male patient or uterus of a female patient. Such catheters may comprise a conduit having one or more bends. Conduits with a general U-shaped bend and a compound curve are within the scope of this disclosure Methods related to the catheters, including methods of use and methods of manufacture, are also disclosed.
Claims20
A catheter comprising:
- a conduit comprising a distal end configured for vascular insertion and a proximal end, wherein the conduit comprises a general U-shaped bend near the distal end of the conduit, wherein the conduit further comprises a compound curve between the general U-shaped bend and the distal end, wherein the compound curve comprises a first curve and a second curve, and wherein the second curve is configured to orient the distal end of the conduit towards a straight portion of the conduit and away from the general U-shaped bend.
A method of using a catheter comprising:
- inserting a catheter comprising a conduit into a femoral artery on one side of a patient;
- directing the catheter through an external iliac artery on that side of the patient;
- directing the catheter through a common iliac artery on that side of the patient;
- directing the catheter through a common iliac artery on another side of the patient;
- resting a generally U-shaped bend in the conduit of the catheter in a bifurcation of both of the common iliac arteries from an aorta artery;
- and
- placing a distal end of the conduit in or near a mouth of an internal iliac artery on the other side of the patient, wherein the conduit distal to the general U-shaped bend is configured to conform generally to a shape of a right or left common iliac artery of an average patient.

A method of manufacturing a catheter, the method comprising:
- extruding a tube;
- inserting a mandrel into a lumen of the tube, wherein the mandrel comprises a general U-shaped bend near the distal end of the mandrel, wherein the mandrel further comprises a compound curve between the general U-shaped bend and the distal end of the mandrel, wherein the compound curve comprises a first curve and a second curve, wherein the second curve is configured to orient the distal end of the mandrel towards a straight portion of the mandrel and away from the general U-shaped bend of the mandrel;
- setting the shape of the tube to that of the mandrel;
- and
- removing the mandrel from the tube.
