Abstract
The present technology relates generally to devices and methods for closing percutaneous punctures, and more particularly to a multi-lumen tamper for such a device. A vascular closure device for sealing a percutaneous puncture in a wall of a body passageway is disclosed, the vascular closure device including a plug configured to engage a surface of the puncture; a suture configured coupled to the plug; a locking member configured to engage the plug; and a tamper comprising a first lumen and a second lumen.
Claims20
A vascular closure device configured to seal a percutaneous puncture in a wall of a body passageway, the vascular closure device comprising:
- a plug configured to engage a surface of the puncture;
- a suture coupled to the plug;
- a locking member coupled to and slidable along the suture;
- and
- a tamper slidably coupled to the suture at a location that is proximal to the locking member, the tamper having a proximal end, a distal end spaced from the proximal end along an axis, a first lumen that extends from the proximal end to the distal end along the axis, and a second lumen that extends from the proximal end to the distal end along the axis, wherein the first lumen and the second lumen each have a cross-sectional dimension that inhibits the locking member from being pushed inside either of the first and second lumens when the tamper slides along the suture to tamp the locking member against the plug.
A drug delivery kit, comprising:
- a sealing unit configured to seal a percutaneous puncture in a wall of a body passageway, the sealing unit having
- a tamper associated configured to slide along a guidewire, wherein the tamper has a first lumen and a second lumen;
- and
- a pharmaceutical agent releasably carried in at least one of the first lumen and the second lumen.
A deployment instrument, comprising:
- a sealing unit having a tamper, wherein the tamper comprises at least two lumens, the sealing unit configured to transition from a pre-deployment state into a deployed state;
- a carrier device configured to a) hold the sealing unit in the pre-deployment state, b) cause the sealing unit to transition from the pre-deployment state into the deployed state.
