Abstract
A bypass device may include an elongate member extending from a proximal end toward a distal end, and a proximal opening and a distal opening coupled to one another by a lumen disposed through the elongate member. The bypass device also may include at least one port extending through a side surface of the elongate tubular member, wherein at least a portion of the bypass device may be bioabsorbable.
Claims13
A stent, comprising:
- a tubular frame having a proximal end opposite a distal end, wherein a lumen extends between the proximal and distal ends, the tubular frame comprising:
- a flared section at the proximal end, wherein the flared section includes a sloped portion;
- a plurality of anchoring features extending radially outward from an outer surface of the proximal end, wherein the plurality of anchoring features are located adjacent to the sloped portion of the flared section, wherein each of the plurality of anchoring features are both longitudinally and radially staggered from adjacent anchoring features;
- an intermediate section extending from the flared section and positioned between the proximal and distal ends, wherein a diameter of the flared section is greater than a diameter of the intermediate section, wherein the intermediate section includes a plurality of ports extending through the intermediate section, and wherein the intermediate section includes a plurality of radiopaque markers corresponding to a position of each of the plurality of ports;
- and
- a coating extending partially along a surface of the tubular frame, and configured to inhibit tissue in-growth into the stent, wherein the coating is spaced apart from the plurality of anchoring features of the flared section to promote tissue ingrowth at the flared section.

A method, comprising:
- deploying a system within a gastrointestinal (GI) tract of a patient, the system comprising:
- a stent comprising:
- a tubular frame having a first end opposite a second end, wherein a lumen extends between the first and second ends, and wherein the tubular frame comprises:
- a flared section at one of the first or second ends;
- an intermediate section extending from the flared section, wherein a diameter of the flared section is greater than a diameter of the intermediate section;
- a plurality of ports extending through the intermediate section, each of the plurality of ports having a radiopaque marker corresponding to a position of each respective port;
- and
- a coating extending partially along a surface of the tubular frame, wherein the coating is configured to inhibit tissue in-growth into the stent and spaced from an anchoring feature on the flared section, and wherein the anchoring feature is exposed to the GI tract to promote attachment to tissue along the GI tract;
- and
- positioning the flared section along one side of a GI tract target site, positioning the intermediate section directly adjacent the GI tract target site, and introducing fluid or therapeutic material through the ports during treatment.
