Abstract
A pancreatic stent includes a main body convertible between a compressed configuration for delivery and an expanded configuration once deployed, the main body including an inner surface defining a stent lumen and an outer surface. A plurality of drainage features are formed within the outer surface of the main body, the plurality of drainage features permitting placement of the pancreatic stent within a patient's pancreas without blocking side branches of the pancreas.
Claims20
A medical stent comprising:
- a main body convertible between a compressed configuration for delivery and an expanded configuration once deployed, the main body including an inner surface defining a stent lumen and an outer surface;
- and
- a plurality of drainage features formed within the outer surface of the main body, the plurality of drainage features permitting placement of the medical stent within a patient's body structure without blocking side branches of the body structure.
A medical stent comprising:
- an expandable metal support structure that is convertible between a compressed configuration for delivery and an expanded configuration once deployed;
- a polymeric covering disposed over the expandable metal support structure, the polymeric covering expandable with the expandable metal support structure;
- and
- a plurality of drainage features formed in the medical stent, the plurality of drainage features permitting placement of the medical stent within a patient's body structure without blocking side branches of the body structure.
A method of manufacturing an expandable medical stent including drainage features, the method comprising:
- using a mandrel having a high-low pattern formed within an outer surface of the mandrel to braid an expandable metal support structure having a high-low pattern in at least some adjacent windings;
- removing the expandable metal support structure from the mandrel;
- and
- forming a polymeric layer over the expandable metal support structure;
- wherein the polymeric layer conforms to the high-low pattern of the expandable metal support structure to form the drainage features.
