An implantable device for branched lumens with associated systems and methods

A delivery system comprising:

• an implantable device including a main body and a side branch, the main body including a tubular member and a stent member supporting the tubular member, the tubular member forming a primary lumen having a first opening and a second opening, the tubular member forming a secondary lumen having an aperture defined through the tubular member and having a proximal opening proximal the second opening of the tubular member;
• an elongate member having a first end and a second end, the main body of the implantable device being positioned at the first end of the elongate member, the elongate member defining a delivery lumen extending along at least a portion of a longitudinal length of the elongate member and through which the side branch is operable to be delivered;
• a catheter olive positioned at the first end of the elongate member such that the main body of the implantable device is positioned longitudinally between a leading tip of the catheter olive and the second end of the elongate member;
• a constraining member positioned about the main body and constraining the main body to a delivery configuration;
• and
• a secondary constraining member positioned about the stent of the main body, the secondary constraining member operable to constrain the main body to a partially constrained configuration.

A delivery system comprising:

• an implantable device including a main body and a side branch, the main body including tubular member and stent member supporting the tubular member, the tubular member forming a primary lumen having a first opening and a second opening, the tubular member including a column defining a secondary lumen and having an aperture defined through the tubular member and having a column opening proximal the second opening of the tubular member;
• an elongate member having a first end and a second end, the main body of the implantable device being positioned proximal to the first end of the elongate member, the elongate member defining a lumen through which the side branch is operable to be delivered;
• a catheter olive positioned at the first end of the elongate member such that the main body of the implantable device is positioned longitudinally between a leading tip of the catheter olive and the second end of the elongate member;
• a constraining member positioned about the main body and constraining the main body to a delivery configuration;
• and
• a guide member extending from the lumen of the elongate member, through the secondary lumen of the tubular member from the proximal opening and through the aperture, and coupled to the catheter olive.
