20110224660 | Diode Laser Induced Vapor/Plasma Mediated Medical Procedures and Device - An improved method and device for safe and efficient medical applications is provided. In a preferred embodiment, based on using the inherent benefits of laser diodes (such as efficient power generation from a reliable and compact solid state device), plasmas and high energy vapors are produced for medical applications with power levels and power densities sufficient to treat medical indications and avoid the creation of extensive damage zones. Transmissions means in different configurations are used to achieve a high power density, which is able to initiate plasma and high-energy vapor at the tip. Once a sparkless plasma and high energy vapor bubbles are formed, it is often found that it will also absorb other wavelengths in addition to the one that initiated it. As a consequence, other wavelengths more efficiently generated by diodes or diode pumped lasers may be added into the beam in order to improve treatment efficiency. For example, the 1470 nm wavelength can be used to produces sparkler-less plasma bubbles, together with the 980 nm wavelength to produce tissue vaporization and an excellent haemostasis effect. Once plasma and or high-energy vapors are in place, radiation from this zone determine tissue effects. In another embodiment, high peak power pulsed radiation is used.

20110224708 | Angioplasty Device - The invention relates to an angioplasty device for treating stenoses or occlusions that facilitates the diagnosis and visualisation of the stenosis and the treatment control having a duct dedicated to the injection of the contrast product. | 2011-09-15 |
20110224709 | METHODS, SYSTEMS AND DEVICES FOR CARPAL TUNNEL RELEASE - Described herein are methods, systems and devices for cutting a ligament of a patient. In some embodiments, the method may include the steps of advancing a cannulated probe into a patient, advancing the distal end of the tissue modification device assembly posteriorly through the skin of the patient such that it exits the patient, exposing at least one tissue modification element of the tissue modification device assembly, and reciprocating at least a portion of the tissue modification device assembly by alternately pulling on proximal and distal portions of the tissue modification device assembly to draw the at least one tissue modification element across the ligament to cut the ligament, in some embodiments, the system may include a probe, a tissue modification device, and a sheath. The tissue modification device may include a proximal handle, at least one tissue modification element configured cut ligament, and a sharp distal tip. | 2011-09-15 |
20110224710 | METHODS, SYSTEMS AND DEVICES FOR CARPAL TUNNEL RELEASE - Described herein are methods, systems, and devices for performing a minimally invasive carpal tunnel release procedure to cut a target transverse carpal ligament. In some embodiments, the method may include the steps of advancing a probe percutaneously though a patient's skin from a first location, advancing a tissue modification device from the first location and between the target ligament and non-target tissue so that a proximal handle on the tissue modification device extends from the patient at the first location, attaching a distal handle in communication with the distal end of the tissue modification device. In some embodiments, a system may include a probe configured to be advanced percutaneously though a patient's skin from a first location, a tissue modification device comprising a proximal handle and a flexible distal region having uni-directional blades, and a distal handle configured to connect to the distal end of the tissue modification device. | 2011-09-15 |
20110224711 | Ring Handled Device and Method of Manufacturing Same - A device, and a method of making the device, having at least one blank having a handle end and an operative end are described. The device may include a handle end having spaced complementary formations configured to co-unite to form a ring-shaped handle end. The method may include forming spaced complementary formations in the handle end of the blank, and co-uniting the spaced complementary formations to form a ring-shaped handle end in the blank. | 2011-09-15 |
20110224712 | LANCING SYSTEM FOR WITHDRAWING A BODY FLUID - Lancing system for withdrawing body fluid having a lancing element and a lancing instrument , which includes a lancing drive, by which a lancing movement of a lancing element is driven. The lancing drive comprises a drive source and a transmission having a housing coupling mechanism which includes at least two transmission links, a housing bearing, and a coupling element adapted for coupling a lancing element thereto. A lancing depth limiting stop is positioned in the housing so that a stop surface of the lancing element contacts the lancing depth limiting stop during the forward phase of the lancing movement. The housing coupling mechanism comprises a length compensation device to ensure a distance adaptation of the spacing between the lancing element and a housing bearing of the housing coupling mechanism during contact of the stops and further movement of the lancing drive. | 2011-09-15 |
20110224713 | SLOTTED INTRODUCER NEEDLE AND METHOD FOR ACCESSING A BODY LUMEN - An introducer needle for accessing a body lumen includes an annular-shaped body having a distal end and a proximal end, a leading edge formed on the distal end, and a slot defined in the leading edge and extending proximally from the distal end. In at least one example, the slot can be include a first edge and a second edge, the first edge and the second edge each extending proximally from the leading edge and being separated by a central angle greater than 90 degrees and less than 360 degrees. The first end and the second edge are in continuous communication with the leading edge. | 2011-09-15 |
