  • Publication number: 20140277026
    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: 20140257272
    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.

  • Patent number: 8696699
    Abstract: An endovascular valve device for use in a vessel during a therapy procedure includes a catheter having at its distal end a valve. The valve is constructed of a braid of elongate first filaments coupled together at their proximal ends in a manner that the first filaments are movable relative to each other along their lengths. The first filaments have a spring bias that radially expands the valve. A filter is provided to the braid formed by electrostatically depositing or spinning polymeric second filaments onto the braided first filaments. The lumen of the catheter is in communication with the center of the valve.

  • Publication number: 20130226166
    Abstract: A neuromodulation device includes an ablation valve with electrodes provided about its circumference. The valve dynamically reacts to fluid pressure within the vessel. When a pressure within and distal said ablation valve is greater than the body fluid pressure within the vessel, said ablation valve closes and the electrodes move out of contact with the endothelium of the vessel. When a pressure within and distal the ablation valve is less than the body fluid pressure upstream of the valve, the valve opens such that the electrodes are in circumferential contact with the endothelium. Fluid can be injected into the valve to alter the local pressure about the valve and force the electrodes into contact with the endothelium.

  • Patent number: 8491483
    Abstract: Highly specific measurements of flow in vessels, such as the coronary artery, can be obtained by processing cubic fundamental information. By showing flow in vessels with a high degree of contrast-to-tissue specificity, ultrasound based 3D contrast agent based coronary artery angiograms may be possible. Measurement and display of the velocity of agent from the cubic fundamental signal is provided simultaneously with display of cubic fundamental energy, such as providing a display map indexed by both energy and velocity. High pulse repetition frequency (PRF) for cubic fundamental detection in conjunction with long velocity measurement intervals may increase low velocity sensitivity and measurement precision. Pulsed wave (PW) Doppler may be improved by using a cubic fundamental sensitive pulse sequence.

  • Publication number: 20130079731
    Abstract: A flow directional infusion device includes a filter valve located at the distal end of a catheter. The filter valve constrains delivery of an embolic agent through the catheter to the locus of the aneurysm. In order to provide such delivery, the valve includes a longitudinal opening, radial opening or is otherwise partially permeable in a direction of the aneurysm so that the embolic agent or a delivery element for such agent is limited toward the aneurysm. In addition, the filter valve permits and directs blood flow within the blood vessel about the aneurysm during the treatment without obstructing the vessel and without allowing retrograde flow of the embolic agent in the vessel upstream of the aneurysm.
