Sealing device and delivery system

Abstract

A medical device for sealing a defect in a body includes a wire frame that includes a plurality of wires that form a first occluding member and a second occluding member. In some embodiments, a sealing member is in contact with the wire frame. In some embodiments, the sealing member is configured to define one or more openings in the sealing member.

What is claimed is: 
     
         1 . A medical device comprising:
 a sealing member;   a delivery system coupled to the sealing member, the delivery system operable to deliver and deploy the sealing member, the delivery system including:   a first and second elongate members including a first end and a second end, the sealing member releasably coupled at the first end;   a third elongate member including a lumen, the first and second tubes at least partially positioned within the lumen of the third elongate member, the third elongate member operable to constrain the sealing member when the sealing member is positioned within an elongate member;   a handle, wherein the first, second, and third elongate members extending from the handle, the handle including:   a housing defining a slot extending along at least a portion of a longitudinal length of the housing;   a first linear actuator positioned within the slot of the handle; and   a mandrel control lever operable to rotate when the first linear actuator is linearly translated.   
     
     
         2 . The medical device of  claim 1 , further comprising a slider rod, wherein the mandrel control lever is operable to rotate about the slider rod. 
     
     
         3 . The medical device of  claim 2 , further comprising a sizing insert positioned in the housing and including a first notch, wherein linear translation of the first linear actuator is operable to move the first linear actuator free of the first notch in the sizing insert and limits proximal or distal translation of the second elongate member. 
     
     
         4 . The medical device of  claim 3 , wherein the sizing insert includes a second notch, a distance between the first notch and the second notch being about a length of the sealing member. 
     
     
         5 . The medical device of  claim 1 , wherein the delivery system further includes a spring, the first linear actuator positioned within the slot in the handle against the spring. 
     
     
         6 . The medical device of  claim 1 , wherein the delivery system further includes a second linear actuator positioned in a second slot of the housing and operable to move the third tube when translated linearly. 
     
     
         7 . The medical device of  claim 6 , further comprising a sizing insert positioned in the housing, the second linear actuator operable to move the mandrel control lever, the sizing insert, and second tube. 
     
     
         8 . The medical device of  7 , wherein the handle further includes a lock release actuator coupled to the second linear actuator and operable to release the second linear actuator from a locked condition to an unlocked condition. 
     
     
         9 . The medical device of  claim 1 , further comprising a retrieval cord operable to be secured to the first linear actuator. 
     
     
         10 . The medical device of  claim 9 , wherein the first linear actuator includes recessed teeth formed in a top portion of the first linear actuator, the recessed teeth operable to secure the retrieval cord. 
     
     
         11 . The medical device of  claim 9 , wherein first linear actuator includes a retrieval cord locking ring operable to secure the retrieval cord. 
     
     
         12 . The medical device of  claim 10 , wherein the handle further includes a thumb wheel positioned on the housing and operable to rotate and wind the retrieval cord around a portion of the thumb wheel. 
     
     
         13 . The medical device of  claim 12 , wherein the portion of the thumb wheel about which the retrieval cord is operable to be wound includes a retrieval cord groove.
