Abstract
The present disclosure relates generally to the field of medical devices and establishing fluid communication between body lumens. In particular, the present disclosure relates to devices and methods for establishing a controlled flow or access passage between body lumens.
Claims8
A medical device, comprising:
- an elongate tubular body comprising a proximal portion, a distal portion, and a length therebetween, the elongate tubular body defining a lumen along the length;
- the elongate tubular body having an unexpanded configuration, and an expanded configuration wherein the proximal portion expands into a proximal retention member and the distal portion expands into a distal retention member leaving a length of a saddle region extending therebetween;
- and
- two flexible collars disposed around the saddle region along separate portions of the length of the saddle region;
- wherein each of the flexible collars is configured to constrict at least a portion of the saddle region to define a fluid reservoir between the flexible collars, and to allow controlled flow of fluid from the reservoir to be delivered through a lumen defined by at least one of the collars.
