Abstract

An implant for occluding a left atrial appendage may include an expandable framework including a body portion and a disk portion, wherein the expandable framework is configured to shift between a collapsed configuration and an expanded configuration, and an occlusive disk element disposed within the disk portion. The disk portion may include a first disk portion integrally formed with the body portion, and a second disk portion movably attached to the first disk portion by at least one hinge member.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An implant for occluding a left atrial appendage, comprising:
 an expandable framework configured to shift between a collapsed configuration and an expanded configuration;   wherein the expandable framework includes a body portion and a disk portion;   wherein the expandable framework includes a proximal hub and a distal hub;   wherein the distal hub is disposed within an interior of the body portion.   
     
     
         2 . The implant of  claim 1 , wherein the disk portion is spaced apart from the body portion in the expanded configuration. 
     
     
         3 . The implant of  claim 1 , wherein the proximal hub is disposed proximal of the body portion. 
     
     
         4 . The implant of  claim 1 , further comprising an occlusive element secured to the body portion. 
     
     
         5 . The implant of  claim 1 , further comprising an occlusive disk element secured to the disk portion. 
     
     
         6 . The implant of  claim 5 , wherein the occlusive disk element is disposed within the disk portion. 
     
     
         7 . The implant of  claim 1 , wherein a neck portion extends from the body portion to the disk portion. 
     
     
         8 . An implant for occluding a left atrial appendage, comprising:
 an expandable framework configured to shift between a collapsed configuration and an expanded configuration;   wherein the expandable framework includes a body portion and a disk portion;   wherein the expandable framework includes a proximal hub and a distal hub;   wherein the distal hub faces toward the proximal hub.   
     
     
         9 . The implant of  claim 8 , wherein the proximal hub is disposed proximal of the body portion. 
     
     
         10 . The implant of  claim 8 , wherein the proximal hub is disposed proximal of the disk portion. 
     
     
         11 . The implant of  claim 8 , further comprising an occlusive element secured to the body portion. 
     
     
         12 . The implant of  claim 8 , further comprising an occlusive disk element secured to the disk portion. 
     
     
         13 . The implant of  claim 12 , wherein the occlusive disk element is disposed within the disk portion. 
     
     
         14 . The implant of  claim 8 , wherein at least a portion of the distal hub is disposed proximal of a distalmost extent of the body portion in the expanded configuration. 
     
     
         15 . An implant for occluding a left atrial appendage, comprising:
 an expandable framework configured to shift between a collapsed configuration and an expanded configuration;   wherein the expandable framework includes a body portion and a disk portion;   wherein the expandable framework includes a proximal hub and a distal hub;   wherein at least a portion of the distal hub is disposed proximal of a distalmost extent of the body portion in the expanded configuration.   
     
     
         16 . The implant of  claim 15 , wherein the disk portion includes a proximal disk portion and a distal disk portion movable relative to the proximal disk portion when the expandable framework shifts between the collapsed configuration and the expanded configuration. 
     
     
         17 . The implant of  claim 16 , further comprising an occlusive disk element secured to the disk portion. 
     
     
         18 . The implant of  claim 17 , wherein the occlusive disk element is disposed between the proximal disk portion and the distal disk portion in the expanded configuration. 
     
     
         19 . The implant of  claim 15 , further comprising an occlusive element secured to the body portion. 
     
     
         20 . The implant of  claim 19 , further comprising an occlusive disk element secured to the disk portion.
