A medical assembly includes a platform which is securely mountable to an operating room fixture, and a plurality of arms or arm modules coupled to the platform and each with a grasper for holding a surgical instrument or port. The medical assembly is particularly applicable for laparoscopic surgery although it is not limited thereto.

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.

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.

An apparatus is provided for applying compression therapy to an extremity of the human body, such as a portion of the human leg. The device includes a flexible member and an air bladder. The flexible member is adapted to wrap around the extremity to secure the air bladder chamber to the extremity. An air pumping mechanism is operated to inflate the air bladder chamber to a pressurized state. One or more fluid-filled pressurized members are provided, each separate and distinct from the flexible member and the air bladder chamber and thus readily moveable relative to the flexible member and the air bladder chamber. The pressurized member(s) preferably includes a sponge on its underside and is operably disposed between the extremity and the flexible member whereby it applies increased localized pressure to the extremity during use. The pressurized member(s) can be positioned during use such that it covers a venous ulcer (or other treatment sites) and applies increased localized pressure to the treatment site in order to promote healing.

A device is provided for applying pressure to the human leg for use in conjunction with treatment of varicose veins. The device includes a flexible member and at least one air bladder chamber integral thereto that are adapted to securely wrap around the human leg. A tube in fluid communication with the air bladder chamber(s) extends to an air pumping mechanism that operates to inflate the air bladder chamber(s) to a pressurized state. The flexible member preferably includes an opening at the knee joint level to enable a patella to protrude therethrough. In addition, the flexible member preferably extends below knee joint level and is adapted to securely wrap around a lower portion of a leg to provide stability to the leg. Preferably, the air bladder chamber of the device is substantially longer in a first dimension than in a second dimension orthogonal thereto such that the air bladder chamber can be positioned to cover a portion of the human leg that is relatively long in the vertical dimension and narrow in the horizontal dimension.

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.

A rake retractor for use in minimally invasive medical procedures such as laparoscopic surgery includes a handle shaft, rake prongs, and end configurations that can be used to move elements within a body cavity. The prongs of the rake retractor are biased to an open position such that when the rake prongs extend out of the needle they open, and they are closed by relative movement of the needle over them. The end configurations are offset so that they may be compactly brought together within the narrow space of a needle having a diameter typically not greater than 2. 5 mm.

Various blood vessel occlusion devices including plugs (), or at least portions thereof, are made of silicone or other biocompatible material and each including a pilot hole () which permits an insertion device () to be used to insert the plugs into the blood vessel. The plugs allow blood vessels to be rapidly occluded. Certain embodiments of the plug may be used to permanently seal the blood vessel, while other embodiments of the plug are designed to temporarily occlude a blood vessel. The plugs are designed to be effective even in cases of deposits in the artery.
