Abstract

An implant assembly for introducing and positioning implants within patients may comprise an implant device, an implant, and a sheath. The implant device may include a head, an upper beam, a lower beam, and an implant positioning component. The implant may be disposed between the upper beam and the lower beam and may include a first face engaged with the upper beam and a second face engaged with the lower beam. Additionally, the implant may be at least partially disposed around the implant positioning component. The sheath may be disposed around the implant positioning device and the implant.

Claims (43)

1 . An implant delivery assembly for delivering a sheet-like implant, comprising:

a sheet-like implant having a first face;

an outer tubular shaft with a distal end and a proximal end;

an inner elongate shaft having a distal end and a proximal end;

wherein the inner elongate shaft is slidably disposed within the outer tubular shaft;

an implant positioning component including an elastically deformed undeployed configuration and a deployed configuration, the implant positioning component comprising:

a trunk;

a first opposed pair of flexible arms extending away from the trunk, the first opposed pair of flexible arms adapted to engage the first face of the sheet-like implant; and

a second opposed pair of flexible arms extending away from the trunk, the second opposed pair of flexible arms adapted to engage the first face of the sheet-like implant;

wherein the first opposed pair of flexible arms extends away from a first attachment location positioned along the trunk to their respective free ends and the second opposed pair of flexible arms extends away from a second attachment location positioned along the trunk to their respective free ends, and wherein the first attachment location is spaced a fixed distance away from the second attachment location along a length of the trunk.

2 . The implant delivery assembly of claim 1 , wherein the first opposed pair of flexible arms and the second opposed pair of flexible arms extend at fixed angles from the trunk.

3 . The implant delivery assembly of claim 1 , wherein the implant positioning component is a monolithic structure including the trunk and the first opposed pair of flexible arms and the second opposed pair of flexible arms.

4 . The implant delivery assembly of claim 1 , wherein the sheet-like implant is at least partially disposed around the implant positioning component in the elastically deformed undeployed configuration.

5 . The implant delivery assembly of claim 4 , wherein the first face is a convex face of the sheet-like implant in the deployed state.

6 . The implant delivery assembly of claim 1 , wherein the outer tubular shaft moves longitudinally relative to the inner elongate shaft and the implant positioning component to transition the implant positioning component from the elastically deformed undeployed configuration to the deployed configuration.

7 . The implant delivery assembly of claim 1 , wherein the implant positioning component comprises a flexible metal.

8 . An implant delivery assembly for delivering a sheet-like implant, comprising:

a sheet-like implant having a first face;

a handle;

an elongate shaft extending from the handle to a distal end of the elongate shaft;

an implant positioning component including an elastically deformed undeployed configuration and a deployed configuration, the implant positioning component comprising:

a trunk;

a first opposed pair of flexible arms adapted to engage the first face of the sheet-like implant and extending away from the trunk at a first attachment location along the trunk; and

a second opposed pair of flexible arms adapted to engage the first face of the sheet-like implant and extending away from the trunk at a second attachment location along the trunk spaced apart from the first attachment location.

9 . The implant delivery assembly of claim 8 , wherein actuation of the handle transitions the implant positioning component from the elastically deformed undeployed configuration to the deployed configuration.

10 . The implant delivery assembly of claim 8 , wherein the first opposed pair of flexible arms extends away from the first attachment location positioned along the trunk to their respective free ends and the second opposed pair of flexible arms extends away from the second attachment location positioned along the trunk to their respective free ends, and wherein the first attachment location is spaced a fixed distance away from the second attachment location along a length of the trunk.

11 . The implant delivery assembly of claim 8 , wherein the first opposed pair of flexible arms and the second opposed pair of flexible arms extend at fixed angles from the trunk.

12 . The implant delivery assembly of claim 8 , wherein the implant positioning component is a monolithic structure including the trunk, the first opposed pair of flexible arms and the second opposed pair of flexible arms.

13 . The implant delivery assembly of claim 8 , wherein the sheet-like implant is at least partially disposed around the implant positioning component in the elastically deformed undeployed configuration.

14 . The implant delivery assembly of claim 13 , wherein the first face is a convex face of the sheet-like implant in the deployed state.

15 . The implant delivery assembly of claim 8 , wherein the elongate shaft is a tubular shaft.

16 . An implant delivery assembly for delivering a sheet-like implant, comprising:

a sheet-like implant having a face;

an elongate shaft extending proximally from a distal end of the elongate shaft;

an implant positioning component including an elastically deformed undeployed configuration and a deployed configuration, the implant positioning component comprising:

a trunk;

a first opposed pair of flexible arms adapted to engage the face of the sheet-like implant, the first opposed pair of flexible arms extending away from the trunk at a first location along a length of the trunk; and

a second opposed pair of flexible arms adapted to engage the same face of the sheet-like implant, the second opposed pair of flexible arms extending away from the trunk at a second location along a length of the trunk;

wherein the first opposed pair of flexible arms and the second opposed pair of flexible arms hold the sheet-like implant in a position when deployed in which the sheet-like implant is largely parallel with the elongate shaft.

17 . The implant delivery device of claim 16 , wherein the second location is spaced apart from the first location.

18 . The implant delivery device of claim 16 , wherein the trunk is largely parallel with the elongate shaft.

19 . The implant delivery assembly of claim 16 , wherein the sheet-like implant is at least partially disposed around the implant positioning component in the elastically deformed undeployed configuration.

20 . The implant delivery assembly of claim 16 , wherein the first face is a convex face of the sheet-like implant in the deployed state.
