Abstract
A suture cutting device including a housing, a cutting member, a suture recess, and an actuator. The cutting member is positioned in the housing. The suture recess is formed in the housing and configured to releasably connect the housing to the suture. The actuator is accessible outside of the housing and operable to move the cutting member laterally relative to the suture within the housing from a first position out of contact with the suture to a second position cutting the suture.
Claims26
A suture cutting device, comprising:
- a housing;
- a cutting member positioned in the housing;
- a suture recess formed in the housing and configured to releasably connect the housing to a suture;
- an actuator accessible outside of the housing and operable to move the cutting member laterally relative to the suture within the housing from a first position out of contact with the suture to a second position cutting the suture.
A suture cutting device, comprising:
- a housing comprising:
- a housing interior;
- a suture connection feature configured to releasably connect the housing to a suture with the suture passing through the housing interior;
- a cutting member;
- an actuator coupled to the cutting member and operable to move the cutting member within the housing interior to cut the suture.
A method of cutting a suture extending from an incision in a tissue layer, comprising:
- providing a housing, a cutting member, and an actuator, the housing having a contact surface;
- releasably connecting the housing to the suture;
- pressing the contact surface of the housing against an outer surface of the tissue layer;
- operating the actuator to move the cutting member within the housing to cut the suture.
An internal tissue puncture closure and cutting system, comprising:
- a closure device insertable into a tissue puncture, comprising:
- a suture extending from a first end of the closure device to a second end of the closure device;
- an anchor attached to the suture at the second end of the closure device;
- a sealing plug slidingly attached to the suture adjacent to the anchor;
- a driving mechanism operable to compact the sealing plug toward the second end to seal the tissue puncture percutaneously;
- a suture cutting device releasably connected to the suture after withdrawal of the closure device from the tissue puncture, the suture cutting device having a housing and a cutting member operable in a lateral direction within the housing to cut the suture.
A method of sealing a tissue puncture in an internal tissue wall accessible through a percutaneous incision, comprising:
- providing suture cutting device and a tissue puncture closure device, the suture cutting device comprising a housing and a cutting member, the tissue puncture closure device comprising a suture, an anchor, a compaction member, and a sealing plug positioned proximal of the anchor, the suture connected at its distal end to the anchor and the sealing plug;
- inserting the tissue puncture closure device into the percutaneous incision;
- deploying the anchor into the tissue puncture;
- compacting the sealing plug toward the anchor with the compaction member;
- connecting the suture to the suture cutting device;
- operating the cutting member to cut the suture within the housing;
- depositing the anchor and the sealing plug at the tissue puncture.
