Delivery of respiratory therapy

An air delivery system for providing a supply of air from a source of air at positive pressure to an interfacing structure located at the entrance to the airways of a patient includes a manifold adapted to connect with the supply of positive air pressure and at least one tube connected to the manifold and adapted to deliver the supply of air to the interfacing structure. Each tube is structured to allow movement between an open phase in which the tube allows the passage of air and a collapsed phase in which the tube is collapsed. Each tube is structured such that weight of a typical patient's head against bedding apparel is sufficient to collapse the tube from the open phase to the collapsed phase.

Pre-angioplasty serration of atherosclerotic plaque enabling low-pressure balloon angioplasty and avoidance of stenting

ActiveUS20100042121A1Large caliberSafely and accurately dilated and stretchedBalloon catheterCannulasPercutaneous angioplastyDrug eluting balloon
A device and method for intravascular treatment of atherosclerotic plaque prior to balloon angioplasty which microperforates the plaque with small sharp spikes acting as serrations for forming cleavage lines or planes in the plaque. The spikes may also be used to transport medication into the plaque. The plaque preparation treatment enables subsequent angioplasty to be performed at low balloon pressures of about 4 atmospheres or less, reduces dissections, and avoids injury to the arterial wall. The subsequent angioplasty may be performed with a drug-eluting balloon (DEB) or drug-coated balloon (DCB). The pre-angioplasty perforation procedure enables more drug to be absorbed during DEB or DCB angioplasty, and makes the need for a stent less likely. Alternatively, any local incidence of plaque dissection after balloon angioplasty may be treated by applying a thin, ring-shaped tack at the dissection site only, rather than applying a stent over the overall plaque site.

Laser shock peening of medical devices

A laser shock peening process for producing one or more compressive residual stress regions in a medical device is disclosed. A high-energy laser apparatus can be utilized to direct an intense laser beam through a confining medium and onto the target surface of a workpiece. An absorption overlay disposed on the target surface of the workpiece absorbs the laser beam, inducing a pressure shock wave that forms a compressive residual stress region deep within the workpiece. Medical devices such as stents and guidewires having one or more of these compressive residual stress regions are also disclosed.

Non-ablative radio-frequency treatment of skin tissue

A radio-frequency electrode that is specially configured to provide a reasonably uniform electric field distribution at the skin surface of a patient being treated to improve the skin appearance. Harmful burning is avoided by employing one of the following four features: pre-applying to the skin a thermal gel, a known thermally and electrically-conductive material, using low radio-frequency power at 3.8-4 MHz, relying on the natural cooling provided by a highly conductive electrode material, and continuously moving the electrode while in contact with the skin. Preferably, all four features are combined in carrying out the cosmetic procedure of the invention. In a preferred embodiment, the highly conductive electrode material is an alloy comprised mainly of silver with a small percentage of ingredients added to strengthen the silver alloy electrode and preserve its luster and the active surface of the electrode is configured as a section of a sphere, or as dome shaped.

Device and method for opening blood vessels by pre-angioplasty serration and dilatation of atherosclerotic plaque

ActiveUS20090240270A1Safely and accurately dilated and stretchedDilated more evenly and smoothlyBalloon catheterCannulasBlood vessel spasmPercutaneous angioplasty
A device and method for intravascular treatment of atherosclerotic plaque perforates the plaque with microperforations by small sharp spikes to act as serrations for forming cleavage lines or planes in the plaque. In preferred embodiments, expansion may be obtained by mechanical apparatus, expansion balloon, or balloon-assisted deployment. The plaque treatment enables a subsequent balloon angioplasty to be performed without creating substantial dissections and at low balloon pressure so as to avoid injury to the arterial wall. The plaque treatment may include dilatation of the plaque at low pressure, sufficiently that no subsequent balloon angioplasty is needed. The plaque preparation may be followed by applying one or a few ring tacks to secure the compressed plaque with minimal emplacement of foreign material.

Radio-frequency treatment of skin tissue with shock-free handpiece

RF energy for skin conditioning with a non-ablative electrode is applied with a handpiece incorporating means to prevent electrical shock to the patient when the energized electrode surface makes or breaks contact with the skin. In a preferred embodiment, switch means are incorporated in the handpiece and configured such that the active electrode surface is not energized until it is in actual contact with the patient's skin, and remains energized only while the active electrode surface remains in contact with the patient's skin, so that no voltage is present on the electrode, when an air gap whose dielectric breakdown can cause an electrical shock to the patient arises, immediately before or immediately after skin contact during a skin conditioning procedure. In another preferred embodiment, the electrode to skin impedance change as the electrode touches the skin is used to activate a switch that transfers RF to the electrode.
