Abstract
The present disclosure provides medical devices such as self-expanding stents or tissue lumen stents with an overlapping layer. The medical devices can have a coating or cover disposed over all or a portion of the medical device. The overlapping layer define a doubled back portion at an end of the medical device that includes an elongate section to provide dynamic movement of the end of the medical device relative to a central portion of the medical device.
Claims20
A medical device, comprising:
- an elongate tubular body comprising a first end portion, a body portion, and a second end portion opposite the first end portion, the elongate tubular body having a constrained configuration and an unconstrained configuration;
- the first end portion, in the unconstrained configuration comprising a retention member, an elongate section distal to the retention member, and a doubled back portion extending from the elongate section over the retention member towards the second end portion;
- and
- wherein the doubled back portion has a free proximal end unattached to the body portion of the elongate tubular body.

A medical device for placement in an anastomosis, comprising:
- an elongate tubular body comprising a first end portion, a body portion, and a second end portion opposite the first end portion, the elongate tubular body having a constrained configuration and an unconstrained configuration;
- the first end portion, in the unconstrained configuration comprising a retention member, an elongate section distal to the retention member, and a doubled back portion extending from the elongate section over the retention member towards the second end portion,
- wherein the doubled back portion has a free proximal end unattached to the body portion of the elongate tubular body, and wherein the elongate section is configured to provide dynamic movement of the retention member relative to the second end portion.
A medical device, comprising:
- a stent comprising an elongate tubular body comprising a first end portion, a body portion, and a second end portion opposite the first end portion, the elongate tubular body having a constrained configuration and an unconstrained configuration;
- the first end portion, in the unconstrained configuration comprising a retention member, an elongate section distal to the retention member, and a doubled back portion extending from the elongate section over the retention member towards the second end portion;
- and
- a delivery device configured to hold the stent in the constrained configuration and deploy the stent in an anastomosis in the unconstrained configuration;
- wherein the doubled back portion has a free proximal end unattached to the body portion of the elongate tubular body.
