US 2021/0275775 A1 · COMPACT URINARY CATHETER WITH STIFFENING MEMBER

Abstract

A urinary catheter system, the system comprising: a urinary catheter having a distal end configured for insertion into a urethra and a proximal end, the urinary catheter including an elongate tubular member having a lumen extending between the proximal and the distal ends thereof, an elongate stiffening member attached to or embedded within a wall of the elongate tubular member, wherein the stiffening member is predisposed to assume a generally straight shape; a sheath slidably disposed over a portion of the urinary catheter near the distal end and configured to allow the urinary catheter to be advanced into the urethra without directly touching the urinary catheter; an enclosure for housing the urinary catheter, the enclosure comprising: a bottom member comprising a base and an inner wall with an inner hole leading to an inner open portion of the enclosure; and a top member comprising an outer wall with an outer hole leading out of the enclosure, wherein the top member is attached to the bottom member so as to rotate relative to the bottom member about an axis of rotation, wherein rotating the top member or the bottom member relative to the other member causes the urinary catheter to wind into a spiral between the inner wall of the bottom member and the outer wall of the top member; and a urine collection bag attached to the proximal end of the urinary catheter and housed within the inner open portion of the enclosure.

A urinary catheter system, the system comprising:

a urinary catheter having a distal end configured for insertion into a urethra and a proximal end, the urinary catheter including an elongate tubular member having a lumen extending between the proximal and the distal ends thereof, an elongate stiffening member attached to or embedded within a wall of the elongate tubular member, wherein the stiffening member is predisposed to assume a generally straight shape;
a sheath slidably disposed over a portion of the urinary catheter near the distal end and configured to allow the urinary catheter to be advanced into the urethra without directly touching the urinary catheter;
an enclosure for housing the urinary catheter, the enclosure comprising:
a bottom member comprising a base and an inner wall with an inner hole leading to an inner open portion of the enclosure;
and
a top member comprising an outer wall with an outer hole leading out of the enclosure, wherein the top member is attached to the bottom member so as to rotate relative to the bottom member about an axis of rotation,
wherein rotating the top member or the bottom member relative to the other member causes the urinary catheter to wind into a spiral between the inner wall of the bottom member and the outer wall of the top member;
and
a urine collection bag attached to the proximal end of the urinary catheter and housed within the inner open portion of the enclosure.

A method for using a urinary catheter system to void a bladder of a patient, the method comprising:

contacting, with one of the patient's hands, a sheath disposed over a urinary catheter near a distal end of the urinary catheter, the urinary catheter including an elongate tubular member having a lumen extending between the proximal and the distal ends thereof, an elongate stiffening member attached to or embedded within a wall of the elongate tubular member, wherein the stiffening member is predisposed to assume a generally straight shape;
wherein a majority of the urinary catheter is housed in an enclosure comprising a top member and a bottom member, and wherein the distal end of the urinary catheter is located outside an outer hole in the enclosure;
advancing the urinary catheter out of the enclosure by pulling on the urinary catheter via the sheath;
advancing the distal end of the urinary catheter into a urethra of the patient while continuing to contact only the sheath and not the urinary catheter with the patient's hand;
sliding the sheath proximally along the urinary catheter;
advancing the distal end of the urinary catheter through the patient's urethra and into the patient's bladder, using the sheath;
unfolding a urine collection bag attached to a proximal end of the urinary catheter, wherein the urine collection bag is stored in an inner open portion of the enclosure before unfolding;
and
voiding the patient's bladder through the catheter, so that urine passes from the patient's bladder through the urinary catheter and into the urine collection bag.
