20090124944 | Method and Assembly for Treating Venous Ulcers and Wounds - An assembly according to the invention includes a pressure mechanism having a flexible member for attachment to a limb and an air chamber which may be pumped up into a desired pressurized state, a separate relatively small pre-filled air bladder, an absorbent foam, sponge or dressing coupled to the pre-filled air bladder, and a suction conduit coupled to a source of negative pressure (suction) and in fluid communication with the absorbent foam, sponge or dressing. In a preferred embodiment, the pre-filled air bladder, the absorbent foam, sponge or dressing and the suction conduit are formed together as a unit. | 05-14-2009 |
20090204037 | Compression Apparatus for Applying Intermittent Pressure to the Leg - An apparatus applies pressure to a portion of the human body using two fluidly coupled pressurized members. The apparatus includes fluidly coupled foot and leg bladders, each having an inflatable chamber accommodating an entering fluid. Optional straps locate the bladders to portions of the body such as a leg and the bottom of a foot, whereby the apparatus is operated through the walking motion. The foot bladder deflates as the heel strikes the ground, thereby forcing fluid out of the foot bladder, through a fluid conduit, and into the leg bladder, which raises the pressure therein. When the heel is raised, some fluid is forced out of the leg bladder, back through the conduit, and into the foot bladder. This process repeats as a person walks, which creates a pumping or kneading force on the leg, thereby promoting blood flow, drainage, treatment, and healing. | 08-13-2009 |
20090259225 | Minimally Invasive Surgical Needle and Cauterizing Assembly and Methods - A minimally invasive surgical assembly broadly includes an outer hollow needle which has an outer diameter, a longitudinal axis, and a sharp distal end. An insulating member extends through the hollow needle and is movable relative to the hollow needle. An elongated member extends through the insulating member and is movable relative to both the insulating member and the hollow needle. A resilient wire projects from the elongated member and is retractable within and extendable outside of the insulating member and the hollow needle. The insulating member, elongated member, and resilient wire are movable relative to the needle using first and second moving means whereby the surgical assembly assumes various configurations having different operational functions. | 10-15-2009 |
20090275889 | Intravascular Catheter Device for Selective Occlusion of Iliac Vasculature - An improved catheter device for selectively isolating and occluding a portion of the iliac vasculature of a patient includes an elongate hollow catheter shaft which is advanceable though the vascular system of the patient. The catheter shaft has a proximal portion that extends out from the patient and a distal portion adapted to be disposed within the iliac vasculature of the patient. A plurality of expandable members are disposed on the distal portion. One expandable member is dimensioned and configured so that when expanded it rests within the bifurcation of the descending aorta to the common iliac arteries (and/or within the bifurcation of the inferior vena cava that leads to the common iliac veins) so as to fixate the catheter within the iliac vasculature of the patient. At least two other expandable members are spaced apart from the fixation member and configured to selectively isolate and occlude blood flow through different portions of the iliac vasculature. | 11-05-2009 |
20100016884 | Minimally Invasive Surgical Assembly and Methods - A minimally invasive surgical assembly broadly includes an outer hollow needle which has an outer diameter of approximately 2 mm or smaller, and a coaxial surgical instrument having a shaft which extends through the outer hollow needle. The coaxial surgical instrument includes end effectors at the end of the shaft which are biased to an open position such that when the end effectors of the surgical instrument extend out of the needle they open, and they are closed by relative movement of the needle over them. The assembly preferably includes a first fixing element which is used to fix the relative location of the surgical instrument and the needle. The assembly also preferably includes a second fixing element which moves relative to the needle and is located on the outside thereof and which is used to fix the relative location of the needle to the patient. | 01-21-2010 |
20100292724 | Minimally Invasive Surgical Clamps, Assemblies and Methods - A minimally invasive surgical assembly broadly includes an outer tube which has an outer diameter of 3.0 mm or smaller, and a coaxial surgical instrument having a shaft which extends through the outer hollow tube. The coaxial surgical instrument includes end effectors at the end of the shaft. The end effectors include spring arms and wire frame clamp elements defining fenestrations. The spring arms are biased to an open position such that when the end effectors of the surgical instrument extend out of the outer tube they open, and they are closed by relative movement of the outer tube over them. The wire frame clamp elements are biased to an open position such that when they extend out of the outer tube they open and they are closed by relative movement of the outer tube over them. | 11-18-2010 |
20110015491 | SURGICAL ACCESS DEVICE WITH MOVEABLE DEVICE PORT - A surgical access device for use in laparoscopic surgical procedures includes a housing portion and at least one moveable device port. The housing portion has an axial bore extending therethrough, defining a central axis of the surgical access device. The at least one moveable device port is moveable about an annular path corresponding to an annular seal member. Each moveable device port defines a lumen extending therethrough, and each lumen is substantially parallel to the central axis of the surgical access device. | 01-20-2011 |
20110034948 | Catheter Device and Method for Selective Occlusion of Arteries of the Descending Aorta - An improved catheter device includes an elongate shaft having a distal portion adapted to be disposed with the abdominal aorta and a plurality of expandable members disposed thereon. One expandable member is dimensioned and configured so that it rests within the iliac bifurcation when expanded. At least two expandable members are spaced apart from the one expandable member and configured to selectively occlude blood flow to different abdominal/pelvic arteries when expanded. Preferably, the distal-most and the proximal-most expandable members are spaced apart at a distance more than 20 cm and less than 40 cm (and most preferably on the order of 30 cm). The expandable members are preferably realized by four inflatable balloons controlled by fluidic pressure supplied thereto via corresponding inflation lumens in the shaft. The catheter device can be fixated within the abdominal aorta and manipulated in order to quickly and efficiently identify and isolate a hemorrhage flowing from an abdominal artery. In another aspect, the catheter device can be used in treating an abdominal aortic aneurysm. | 02-10-2011 |
20110160538 | SURGICAL INSTRUMENTS FOR LAPAROSCOPIC ASPIRATION AND RETRACTION - Various surgical instruments for laparoscopic procedures is provided, which are adapted and configured to aspirate and retract a hollow organ, such as a gallbladder. The surgical instruments can includes a needle body, an anchor that is deployable with respect to the needle body, which is adapted and configured for engaging and retracting the hollow organ. Moreover, an aperture can be provided in connection with the needle body, which is adapted and configured for permitting aspiration of contents of the hollow organ. The anchor can be held within, and deployable from, a lumen of the needle body, or held on, and deployable from, an outside surface of the needle body, for example. | 06-30-2011 |
