Suture spring device applicator
First Claim
1. An applicator for applying a suture spring device in or in relation to anatomical tissue, said applicator comprisinga storage portion configured to hold at least one suture spring device in a substantially relaxed, contracted state;
- a guide disposed distally of said storage portion and including a hollow, tubular body configured to receive therein a suture spring device in an elastically deformed, expanded state for positioning in or in relation to the anatomical tissue; and
a pusher having a configuration to engage a suture spring device in said guide, said pusher being movable in relation to said guide to control the position of the suture spring device relative to said guide.

Abstract
A suture spring device applicator includes a storage portion configured to hold one or more suture spring devices in a substantially relaxed, contracted state and a guide disposed distally of the storage portion to receive a suture spring device in an elastically deformed, expanded state for positioning in or in relation to anatomical tissue. A pusher is used to bias the suture spring device distally so that, when the guide is rotated and moved proximally relative to the suture spring device, the device will be loaded into the guide in the elastically deformed, expanded state. The guide is then positioned in or in relation to anatomical tissue and is retracted or moved proximally relative to the suture spring device which is held in place by the force of the pusher. When the guide is removed, the suture spring device is no longer restrained and can move from the elastically deformed, expanded state toward the substantially relaxed, contracted state to apply a predetermined force to compress the anatomical tissue. The applicator preferably includes a central channel through which instruments, such as tissue penetrating instruments and tissue grasping instruments can be inserted prior to or during an operative procedure.

22. An applicator for applying a suture spring device in or in relation to anatomical tissue, said applicator comprising
a housing; -
an outer tubular member having a proximal end mounted by said housing and terminating distally at a distal end; an inner member movably disposed in said outer tubular member and including a storage portion configured to hold a suture spring device in a substantially relaxed, contracted state and a guide disposed distally of said storage portion to receive the suture spring device in an elastically deformed, expanded state; a pusher movably disposed in said outer tubular member to engage the suture spring device so that the position of the suture spring device relative to said guide can be controlled; and a drive mechanism coupled with said inner member to move the inner member relative to said outer tubular member when operated. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30)

31. A method of applying a suture spring device in or in relation to anatomical tissue using an applicator having a storage portion and a guide, said method comprising the steps of
storing the suture spring device in a substantially relaxed, contracted state within the storage portion of the applicator; -
elastically deforming the suture spring device from the relaxed, contracted state to an elastically deformed, expanded state; holding the suture spring device in the elastically deformed, expanded state within the guide; positioning the suture spring device in relation to anatomical tissue in the elastically deformed, expanded state using the guide; and removing the guide to allow the suture spring device to move resiliently from the elastically deformed, expanded state toward the relaxed, contracted state to apply a predetermined compressive force to the anatomical tissue. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38)
