Various embodiments of a device are shown and disclosed for closing a vascular access puncture site following percutaneous diagnostic or therapeutic interventional procedures. The vascular closure device is configured to safely and accurately deploy a sealing material that undergoes a phase change when deployed inside the tissue tract. The sealing material may be a solid at room temperature and a liquid or gel at body temperature. Also, the sealing material may change from a liquid or gel to a cubic phase when it comes into contact with bodily fluids.

Vascular closure device having a flowable sealing material

A suture delivery device for insertion into an internal tissue wall opening and delivery of a suturing apparatus to the internal tissue wall is provided. In one embodiment, the suture delivery device comprises at least one carrier tube, at least one leg, and a tensioning device. The at least one carrier tube is configured to house a pusher and a suturing apparatus, the carrier tube having an expulsion end. The at least one leg is coupled to the at least one tube at a first end of the leg. The tensioning device is pivotally coupled to the at least one leg at a second end of the leg. When the at least one leg is in an open position, the tensioning device exerts tension on the leg such that the leg is movably suspended and can pivot about the tensioning device in response to contacting a tissue wall, and the pusher and suturing apparatus are in an delivery configuration for delivery of the suturing apparatus to the internal tissue wall.

Internal suturing device leg suspension system and method of use

An automated needle deployment device is provided. In one embodiment, the automated needle deployment device comprises a pusher, a needle, a tube, and an actuator. The pusher has a needle engaging end. The needle has a sharp end and an opposite end. A suture is associated with the needle. The pusher and needle are slidably disposed within the tube. The actuator comprises a control and a spring and is operatively associated with the pusher. Actuation of the actuator moves the pusher towards the needle expulsion end of the tube such that the needle engaging end of the pusher engages the needle and expels the needle from the tube.

Method and device for automated needle deployment

Various embodiments of a device are shown and disclosed for closing a vascular access puncture site following percutaneous diagnostic or therapeutic interventional procedures. In one embodiment, the closure device includes a vessel locating member, an anchor and a sealing material. The closure device may be configured to deploy the anchor and the sealing material outside of a hole in a blood vessel to close the hole. The vessel locating member may be used to locate the blood vessel to ensure that the anchor and/or the sealing material are properly placed adjacent to the hole. The closure device may also include a tamper member configured to push or tamp the sealing material against the anchor. The closure device may also include a suture that is used to hold the sealing material and the anchor together adjacent to the hole in the blood vessel.

Extra-vascular sealing device and method

A suture attachment device for fastening multiple suture filaments at a wound or surgical site is provided. In one embodiment, the suture attachment device comprises a lock body having a proximal surface and a distal surface and extending along a longitudinal axis. The lock body includes at least two passageways defined between the proximal surface and the distal surface. Each of the passageways are sized and shaped for receiving a suture filament.
