Problems solved by technology

[0006] Although in some cases the "rendezvous" approach may be preferable to standard ERCP procedures, the "rendezvous" approach is time-consuming, requires complex endoscope replacement, and often leaves the clinician without guidewire placement

Embodiment Construction

[0043] The present disclosure generally relates to placement of stents within body lumens. In certain procedures described herein, to place a stent within a body lumen, the lumen wall is pierced and the stent delivery system is advanced through the hole (i.e., access hole) and positioned at the target site (e.g., on emboli). The stent is subsequently deployed from the stent delivery system, and the stent delivery system is withdrawn from the lumen through the same hole. If the hole is uncovered, fluid from the lumen may leak into surrounding tissues and organs, which may cause serious discomfort or other medical complications.

[0044] Described herein are devices, systems, and methods for covering an access hole following withdrawal of a stent delivery system from a body lumen. Described herein are devices, systems, and methods for covering an access hole following withdrawal of a stent delivery system from a body lumen. For example, stents are described that include one o...

Abstract

Methods, apparatuses and systems are described for delivering a stent through an access hole of a body lumen and covering up the access hole after deploying the stent. Stents are described that include a stent body defining a body lumen contact surface area and a deployable member configured to deploy from the stent body and increase the body lumen contact surface area of the stent. Deployable members that hinge, unroll, extend, expand, and coaxially translate with respect to the stent body are described. A system for delivering a stent into a body lumen are described that may include a coverage member configured to at least partially cover the hole in the wall of the stent upon withdrawing a tubular member through the hole in the wall of the stent. Coverage members may include a self-sealing membrane, a flap valve, or a hinged valve.

Description

technical field [0001] The present disclosure generally relates to methods, devices, and systems for delivering a stent into a body lumen through an access hole and covering the access hole after deployment of the stent. Background technique [0002] Diseases and disorders of the gallbladder, pancreas, and bile ducts (ie, the pancreaticobiliary system) are associated with significant morbidity, mortality, and impaired quality of life. Embolisms, tumors, injuries, leaks, inflammations, infections, and lesions may occur in these structures, which may eventually lead to conditions such as biliary colic, cholecystitis, choledocholithiasis, cholelithiasis, pancreatitis, pancreatic duct stone formation, and chronic Abdominal pain and other diseases. Diseases of the pancreaticobiliary system may also be associated with nutritional disorders such as malnutrition, obesity, and high cholesterol. [0003] To treat biliary embolism, a standard endoscopic retrograde cholangiopancreatog...
