When gripping of a suture is required, the resilient member is intentionally over-extended, causing the resilient member to bow and protrude from the distal opening. A suture is then passed into the resulting gap between the sliding hollowing tube and resilient member, the resilient member then allowed to retract back into place, thereby clamping the suture. ## Claims ### Claim 1 A device to grip a suture in an enclosed space comprising: a hollow member with a distal opening; a resilient member within the hollow member; a handle; the hollow member slidably connected to the handle; a split actuator formed from a proximal actuator and a distal actuator, the split actuator sliding with respect to the handle: the proximal actuator controlling motion of the hollow member; the distal actuator controlling motion of the resilient member; whereby a force against an end of the resilient member causes the resilient member to protrude through the distal opening, creating a gap in which the suture may be grasped; whereby motion of the proximal actuator with respect to a body extends and retracts the hollow member; and whereby motion of the distal actuator with respect to the proximal actuator causes the resilient member to protrude through the distal opening. ### Claim 2 (depends on 1) The device of claim 1, further comprising: a slot in which the split actuator slides; and a stop along the slot, the stop preventing further sliding of the proximal actuator, but permitting further sliding of the distal actuator. ### Claim 3 (depends on 1) The device of claim 1, further comprising: a hollow needle, with an entrance and an exit, connected to the handle; the exit of the hollow needle near the distal opening of the hollow member when the hollow member is fully extended. ### Claim 4 (depends on 1) The device of claim 1, further comprising: a handle; the hollow member connected to the handle; a hollow needle, with an entrance and an exit, connected to the handle; the exit of the hollow needle near the distal opening of the hollow member when the hollow member is fully extended. ### Claim 5 (depends on 1) The device of claim 1, wherein the resilient member is formed from a material that prefers to maintain a first shape, and thus creates a force that oppose bending into a second shape. ### Claim 6 A device that allows a user to grip a suture within a patient, the device comprising: a handle; a hollow tube with a distal opening and a tip; the hollow tube connected to the handle; a resilient member within the hollow tube; the resilient member having a first end and a second end; the first end of the resilient member fixed at the tip of the hollow tube; a split actuator formed from a proximal actuator and a distal actuator, the split actuator sliding with respect to the handle: the proximal actuator controlling motion of the hollow tube; the distal actuator controlling motion of the resilient member: whereby the application of pressure against the second end of the resilient member causes the resilient member to deform, protruding from the distal opening, thereby permitting an item to be gripped between the hollow tube and the resilient member; whereby motion of the proximal actuator with respect to a body extends and retracts the hollow tube; and whereby motion of the distal actuator with respect to the proximal actuator causes the resilient member to protrude through the distal opening. ### Claim 7 (depends on 6) The device of claim 6, further comprising: a slot in which the split actuator slides; a stop along the slot, the stop preventing further sliding of the proximal actuator, but permitting further sliding of the distal actuator. ### Claim 8 (depends on 6) The device of claim 6, further comprising: a hollow needle, with an entrance and an exit, connected to the handle; the exit of the hollow needle near the distal opening of the hollow tube when the hollow tube is fully extended. ### Claim 9 (depends on 6) The device of claim 6, further comprising: a hollow needle, with an entrance and an exit, connected to the handle; the exit of the hollow needle near the distal opening of the hollow tube when the hollow tube is fully extended. ### Claim 10 (depends on 6) The device of claim 6, wherein the resilient member is formed from a material that prefers to maintain a first shape, and thus creates a force that opposes bending into a second shape. ### Claim 11 A device for gripping a suture within a patient, the device comprising: a deformable resilient member held within a hollow member; the hollow member including an opening that partially exposes the deformable resilient member; a handle; the hollow member slidably connected to the handle; a split actuator formed from a proximal actuator and a distal actuator, the split actuator sliding with respect to the handle; the proximal actuator controlling motion of the hollow member; the distal actuator controlling motion of the deformable resilient member; whereby when under compression, the deformable resilient member extends through the opening, creating a space for insertion of a suture, and when compression is removed, the deformable resilient member returns to its original position, able to grip a suture between the resilient member and an inner wall of the hollow member; whereby motion of the proximal actuator with respect to a body extends and retracts the hollow member; and whereby motion of the distal actuator with respect to the proximal actuator causes the deformable resilient member to protrude through the distal opening. ### Claim 12 (depends on 11) The device of claim 11, further comprising: a slot in which the split actuator slides; a stop along the slot, the stop preventing further sliding of the proximal actuator, but permitting further sliding of the distal actuator. ### Claim 13 (depends on 11) The device of claim 11, further comprising: a hollow needle, with an entrance and an exit, connected to the handle; the exit of the hollow needle near the distal opening of the hollow member when the hollow member is fully extended. ### Claim 14 (depends on 11) The device of claim 11, further comprising: a handle; the hollow member connected to the handle; a hollow needle, with an entrance and an exit, connected to the handle; the exit of the hollow needle near the distal opening of the hollow member when the hollow member is fully extended. ### Claim 15 (depends on 11) The device of claim 11, wherein the resilient member is formed from a material that prefers to maintain a first shape, and thus creates a force that opposes bending into a second shape.
