A ureteral stent including a tubular body and a first anti-migration feature including one or more projections extending outward from the tubular body. The first anti-migration feature may be configured to be placed entirely within a patient's ureter. The first anti-migration feature may be provided entirely at a proximal bladder section of the tubular body and be configured to not enter the patient's bladder.

Ureteral stent with anti-migration features

A ureteral stent including a tubular body that defines a lumen and has (i) a distal kidney section to be placed in or near a patient's kidney, (ii) a proximal bladder section to be placed within or near the patient's bladder, and (iii) a ureter section between the distal and proximal sections to be placed within the patient's ureter. A first anti-migration feature may be provided at the proximal bladder section. A second anti-migration feature may be provided at the proximal bladder section, the distal kidney section, or both. A proximal end of the tubular body includes a one-way valve that allows fluid to flow out of the lumen, while preventing fluid from entering the lumen.

An article that includes a guidewire and a removable angled guidewire storage device. The guidewire comprises an angled portion that is at an angle relative to a reminder of the guidewire. A distal end of the removable angled guidewire storage device has a conical shape having a wall that is configured to maintain the angled portion of the guidewire at the angle relative to the reminder of the guidewire. A proximal end of the removable angled guidewire storage device has an opening that is adapted to fit over at least a portion of an introducer. The angled guidewire storage device includes an internal channel having walls extending between the conical shape at the distal end of the removable angled guidewire storage device and the opening at the proximal end of the angled guidewire storage device for receiving and holding the guidewire.

A fabricator resource receives an assembly including a first portion of material and a second portion of material. Initially, the first portion of material in the assembly may have a different modulus of elasticity than the second portion of material. The fabricator resource exposes the assembly to one or more heating/cooling cycles. Exposure of the assembly to the one or more heating/cooling cycles modifies a modulus of elasticity of the first portion of material and a modulus of elasticity of the second portion of material to desired target values (such as substantially same or different values).

Ureteral stents include a tubular body defining a lumen and have (i) a distal kidney section to be placed in or near a patient's kidney, (ii) a proximal bladder section to be placed within or near the patient's bladder, and (iii) a ureter section between the distal and proximal sections to be placed within the patient's ureter. A first anti-migration feature may be provided at the proximal bladder section and may include one or more projections extending outward from the tubular body. The first anti-migration feature may extend less than a total length of the proximal bladder section, and may be configured to not enter the patient's bladder. Furthermore, a second anti-migration feature may be provided at the distal kidney section, the proximal bladder section, or both.

A medical device for retrieving small fragments from within a patient's anatomy includes a collection wire configured for entering the patient's anatomy. The collection wire includes a distal end with a plurality of tips that are configured to attract stone fragments from the patient's anatomy.
