    Abstract: Stent delivery device includes an inner member having a distal tip, a stent disposed over a stent receiving region of the inner member, an outer sheath slidable over the inner member, a stent sheath removably coupled to both the distal tip and a distal end of the outer sheath, and a stent expanding element attached to the distal tip and/or the distal end of the outer sheath. The stent expanding element is biased in an elevated position and aids expansion of the stent when the stent sheath is removed. The stent delivery device includes a proximal junction removably coupling the distal end of the outer sheath to the stent sheath, and a proximal junction removably coupling the stent sheath to the distal tip. Each of the proximal and distal junctions are separately actuatable to decouple the stent sheath from either the distal tip or the outer sheath.

    Abstract: The present disclosure relates generally to the field of medical devices and medical device delivery. In particular, the present disclosure relates to medical devices and delivery systems for positioning and delivering medical devices with an unsupported structure, for example, within a distant and/or tortuous portion of body lumen. For example, a delivery system may position a supported structure of a medical device within a proximal portion of a body lumen and an unsupported structure of the medical device within a distal portion of the body lumen. Examples include delivery systems within an unsupported structure of a medical device to be delivered, wherein a number of balloons are arranged un-inflated within the unsupported, with a distal balloon removably attached to a distal portion of the unsupported structure, and the balloons are inflatable in series to deploy the unsupported structure linearly from the distal end of the delivery system.

    Abstract: A gastrointestinal assembly may be deployed within a patient's gastrointestinal tract in order to facilitate drainage of an abscess. The gastrointestinal assembly may include an outer stent and an inner stent disposed within the outer stent. The inner stent divides a volume within the outer stent into a primary passageway through which nutritional contents may pass and a secondary passageway protected from nutritional contents and configured to accommodate a passive drainage system for draining the abscess.

    Abstract: A stent delivery device including an elongate shaft having a proximal region, a distal region and at least one lumen extending therein. The stent delivery device also includes a collapsible frame attached to the distal region of the elongate shaft. The collapsible frame includes a plurality of arms configured to surround a stent such that the plurality of arms define a stent containment region. The stent delivery device also includes an inner member extending within a least a portion of the stent containment region and an actuation member configured to actuate the plurality of arms of the collapsible frame from an expanded configuration to a collapsed configuration.
