Deploying and fixating an implant across an organ wall
First Claim
1. A method for fixating an elongated implant across an organ wall in a subject'"'"'s body, the method comprising:
- providing the implant attached to an implant deployment device, the implant comprising a rigid implant body enclosed with a compressible tubular skirt maintained stretched to an extended narrow form along said implant body;
forming a wall opening in the organ wall;
passing the implant through said wall opening until a chosen distal portion of said tubular skirt extends posteriorly beyond to the organ wall and a proximal portion of said tubular skirt remains anteriorly behind to the organ wall;
while maintaining said tubular skirt proximal portion confined to said extended narrow form, compressing said tubular skirt distal portion to a first expanded form by at least partly regaining a first preformed shape of said tubular skirt distal portion;
while maintaining said tubular skirt distal portion substantially in said first expanded form, compressing said tubular skirt proximal portion to a second expanded form by at least partly regaining a second preformed shape of said tubular skirt proximal portion; and
detaching said implant from said implant deployment device,wherein said implant deployment device comprises a deployment device body comprising an inner member with an inner connector and an outer member with an outer connector, and wherein said providing the implant includes detachably connecting said inner connector to an inner connectee provided at a proximal end of said implant body and detachably connecting said outer connector to an outer connectee provided at a proximal end of said tubular skirt,wherein said detaching said implant from said implant deployment device includes separately and sequentially disconnecting said inner connector from said inner connectee and said outer connector from said outer connectee,wherein disconnecting said inner connector is followed by disconnecting said outer connector,wherein said outer connector is connectable to said outer connectee by means of a grasper arrangement, said grasper arrangement comprising grasping jaws configured for locking onto said outer connectee having a mating recess pattern, and said disconnecting said outer connector includes;
after disconnecting said inner connector, forcing said grasping jaws to retract outwardly using said inner member.

Abstract
Implant deployment device for delivering and deploying an implant. Includes: deployment device body for pushing implant in subject'"'"'s blood vessel, across an interatrial septum and into subject'"'"'s heart left atrium; and a handle operatively connected to deployment device and having controls assigned to selectively operate positioning of the deployment device, to facilitate determining compression extent of an implant body, and detaching of deployment device from the implant. Also disclosed are: a method for fixating an elongated implant across an organ wall in a subject'"'"'s body, and a method for sealing a wall opening in a septal wall in a subject'"'"'s body.
