Abstract: Methods, apparatuses and systems are described for expandable stent delivery apparatus to cover an access site. The method may include delivering the stent through an access site and deploying a distal portion of the stent from within an outer sheath. In some cases, the method may further include pushing a proximal portion of the stent from the outer sheath such that upon fully exiting the outer sheath, the proximal portion extends proximally to at least partially cover the access site with the stent. The system for delivering the stent into the body lumen may include a stent, a stent delivery apparatus, and an outer sheath. The system may further include an internal pusher configured to push a proximal portion of the stent from the outer sheath and axially compress the stent such that upon fully exiting the outer sheath, the proximal portion extends proximally to cover the access site.

Abstract: Methods, apparatuses and systems are described for expandable stent delivery apparatus to cover an access site. The method may include delivering a stent delivery system through an access site, where the stent delivery system comprises a positioning member with a first portion that is rotatable with respect to a second portion, and where the stent is releasably coupled with the first portion of the positioning member.

Abstract: Methods, apparatuses and systems are described for stent delivery and positioning to cover an access site. The method may include delivering the stent through an access site in a wall of the body lumen. In some cases, the method may include repositioning the stent within the body lumen to at least partially cover the access site with the stent. The stent may be repositioned within the body lumen by retracting the stent towards the access site such that a proximal portion of the stent at least partially covers the access site. The stent may then expand within the body lumen. In some cases, the stent may expand within the body lumen by releasing a primary constrainment member from the stent by pulling the primary constrainment member in a proximal direction away from the stent.

Abstract: A percutaneous nephrostomy catheter system includes a nephrostomy catheter lumen, an extension tubing and a collection bag. The extension tubing is inserted into the nephrostomy catheter lumen. The collection bag is fluidly coupled to the extension tubing. A percutaneous nephrostomy catheter system also includes a catheter hub which employs a Luer valve in order to facilitate nephrostomy care so that when the percutaneous nephrostomy system is in place urine flows from the renal pelvis into the nephrostomy catheter lumen, the extension tubing and the collection bag. The Luer valve employs a scalloped Luer-style male connector which, when screwed into the catheter hub allows flow.
