  • Patent number: 9936956
    Abstract: Surgical and percutaneous devices for closing tissue, for example, the left atrial appendage, may have an elongate body with a stiffened proximal portion, a flexible middle portion, a distal portion, a closure element with a loop having a continuous aperture therethrough, and a suture loop. The closure devices may have a malleable member attached to the elongate body that may be configured to retain a curve after a force is applied to the malleable member. System and methods for closing the left atrial appendage may utilize a closure device and a curved guide device, and the closure device and curved guide device may be self-orienting.

  • Publication number: 20180085130
    Abstract: Closure devices and methods for ligating tissue, such as the left atrial appendage, generally, include an elongate body having a first lumen therethrough, a snare loop assembly, a vacuum tube, and an imaging device. The snare loop assembly may include a snare and a suture loop releasably coupled to the snare and may at least partially extend from a distal end of the elongate body. The vacuum tube may be slidably positioned within the first lumen to extend through the snare loop assembly. The imaging device may be disposed within the lumen of the vacuum tube.

  • Publication number: 20170333074
    Abstract: A dermatological skin treatment device is provided. The device comprises a handpiece and a cutting tool, wherein the tool is inserted through the conduit and percutaneously inserted into a tissue disposed within a recessed area of the handpiece. The device and method cut the fibrous structures under the skin that cause cellulite at an angle substantially parallel to the surface of the skin and replace these structures with a non-cellulite forming structure by deploying a highly fibrous mesh through a single needle hole to create a highly fibrous layer directly or through wound healing processes.

  • Publication number: 20170245861
    Abstract: Described here are closure devices and methods for ligating tissue, such as the left atrial appendage. Generally, the closure devices include an elongate body, a snare loop assembly comprising a snare and a suture loop, and a shuttle connected to the snare and releasably coupled to the elongate body and retractable therein. In some variations, the shuttle may be configured to fit into the lumen. In other variations, a handle may be attached to the elongate body, and the handle may comprise a track and a snare control coupled to the track. The handle may be configured to release the shuttle from the elongate body and allow movement of the snare control along the track to retract the snare loop and the shuttle into a lumen of the elongate body.

  • Publication number: 20170042608
    Abstract: Devices and methods for performing subcutaneous surgery in a minimally invasive manner are provided. The methods include application of reduced air pressure in a recessed area of a handpiece placed over a section of skin and drawing the section of skin and subcutaneous tissue into the recessed area. In a subsequent step a tool is inserted through a tool conduit in the handpiece and through the skin into the subcutaneous tissue, enabling the performance of the desired surgery. Common surgical procedures include dissection and ablation. The devices and methods can be directed at the treatment of skin conditions like atrophic scars, wrinkles, or other cosmetic issues, at treatments like or promoting wound healing or preventing hyperhidrosis, or can be used for creating space for various implants.

  • Publication number: 20160249946
    Abstract: A minimally invasive skin treatment system includes a platform having a recessed area on its bottom and one or more injection ports orthogonal to its top, each injection port including a through-hole to the recessed area. The system includes an injection device including a needle slidably disposed in a selective port such that the needle passes into the recessed area and percutaneously through a dermis disposed within the recessed area. A nozzle is configured to discharge a fluid at a high pressure in a direction orthogonal to an axis of the needle and parallel to the top of the platform to cut create a plane of dissection within the subcutaneous tissue.
