Abstract
A hybrid endoprosthetic device comprises a stented tubular part and a branched tubular body connected such that a main lumen of the stented tubular part communicates with a main lumen of the branched tubular body. The branched tubular body has multiple branch lumens for connection with natural vessels of the vasculature, and includes at least one branch lumen for access to facilitate delivery and implantation of the hybrid endoprosthetic device by an endovascular step in a hybrid surgical procedure. The hybrid endoprosthetic device is configured to replace a part of the aorta and common iliac artery. A delivery system for use with the device is also disclosed.
Core Innovation
The disclosure describes a hybrid endoprosthetic device for thoracoabdominal aortic/aorto-iliac replacement. The device includes a stented tubular part having a sleeve defining a lumen with ring stents, and a branched tubular body that defines a main lumen in communication with the stented tubular part. The branched tubular body extends along a longitudinal axis and includes a bifurcated branch tubular body portion, enabling branch lumens to connect to visceral and iliac vessels.
The hybrid endoprosthetic device further includes a plurality of tubular branches extending laterally from the longitudinal axis of the first tubular body portion, including at least one tubular branch with a removable structure forming a distal closed end. An access branch extends from the first tubular body portion, and a collar is provided at the location where the branched tubular body extends from the stented tubular part.
A delivery system is provided that delivers the hybrid endoprosthetic device using an elongate delivery shaft inserted through the access branch, where the delivery shaft has a distal tip at the stented tubular part. A removable sheath compactly restrains the stented tubular part, and a hub at the access branch defines a hub throughbore through which the access branch extends. A splitter mechanism causes the removable sheath to split longitudinally when the sheath is retracted by directing the removable sheath across the splitter mechanism.
Claims Coverage
Independent claim clm-00001 defines four main inventive elements: the hybrid endoprosthetic device structure, the delivery device components, a splitter mechanism that longitudinally splits a removable sheath, and a collar at the transition from the stented tubular part to the branched tubular body.
Hybrid endoprosthetic device with stented sleeve and branched main lumen
A hybrid endoprosthetic device including a stented tubular part having a sleeve defining a lumen and ring stents at the sleeve, and a branched tubular body that defines a main lumen in communication with the stented tubular part, wherein the branched tubular body has a first tubular body portion defining a longitudinal axis and a bifurcated branch tubular body portion extending along the longitudinal axis from the first tubular body portion; a plurality of tubular branches extend laterally from the longitudinal axis of the first tubular body portion, and at least one tubular branch includes a removable structure forming a distal closed end; and an access branch extends from the first tubular body portion.
Delivery device using delivery shaft through access branch with hub throughbore
A delivery device including a delivery shaft inserted through the access branch of the hybrid endoprosthetic device, the delivery shaft having a distal tip at the stented tubular part; a removable sheath compactly restraining the stented tubular part; and a hub at the access branch defining a hub throughbore through which the access branch extends.
Splitter mechanism causing longitudinal splitting of the removable sheath
A splitter mechanism wherein retraction of the removable sheath compactly restraining the stented tubular part by directing the removable sheath across the splitter mechanism causes the sheath to split longitudinally.
Collar at the branched-to-stented transition
A collar at the hybrid endoprosthetic device where the branched tubular body extends from the stented tubular part.
The independent claim is directed to delivering a hybrid endoprosthetic device via an access branch using a delivery shaft and a removable sheath that is longitudinally split by a splitter mechanism during retraction, with a collar provided at the branched tubular body where it extends from the stented tubular part.
