    Abstract: A blood vessel clip, preferably comprising spring quality material, has a head connected to a first leg and a second leg. Preferably, the two legs of the blood vessel clip are in a “V” configuration so that a blood vessel can be located therebetween. The blood vessel clip is adapted so that, when forced axially through a constricted region of a clip applicator, a compressive force is exerted on the head by the constricted region. This compressive force causes the legs of the clip to move closer relative to one another, thereby closing the clip and occluding a blood vessel located between the two legs. A variety of blood vessel clips having different shapes, cross-sections and grooves suitable for occluding a blood vessel are described.

    Abstract: A method and apparatus for dissecting a first layer of tissue from a second layer of tissue and thereafter holding open an anatomic space for the performance of a surgical procedure. The method includes steps of making an incision in a body, introducing a deflated balloon dissector into the incision, inflating the balloon dissector to effect dissection of the first layer of tissue from the second layer of tissue, deploying a retractor within the anatomic space in order to hold open the anatomic space, and optionally deflating or evacuating the balloon dissector to open a cavity for surgical manipulations. The apparatus includes a combined dissector-retractor having a balloon retractor disposed upon the surface of the balloon dissector and integrated therewith.

    Abstract: Apparatus for creating an anatomic space in tissue in a body of a patient using a cannula with proximal and distal extremities and a bore extending therethrough to provide an open end. A balloon having an inflated space is provided. The balloon is capable of assuming collapsed and inflated conditions. A retainer is carried by the balloon for forming the balloon when in a collapsed condition into a generally cylindrical roll to aid in inserting the balloon into the tissue. An obturator shaft having a rounded distal end is sized so that it extends through the cannula and into the roll. A laparoscope can be introduced into the obturator shaft to permit viewing through the obturator shaft and the balloon. An inflation tube is provided for inflating the balloon after it is disposed in the tissue to cause the balloon to progressively expand to create separation forces in the tissue to create the anatomic space.

    Abstract: The present invention provides a device or apparatus for manipulating matter in a confined or inaccessible space, comprising manipulator means at least partly constructed of one or more bent or twisted elongate metallic members having pseudoelasticity at the intended manipulation temperature, and a hollow housing (preferably of elongate tubular form) or cannula capable of holding at least the metallic member(s) in a relatively straightened state, and actuating means for extending the metallic member(s) from the housing to manipulate matter within the said space and for withdrawing the metallic member(s) into the housing, the arrangement being such that the metallic member(s) bend(s) or twist(s) pseudoelastically in a lateral or helical sense to manipulate the matter on extending from the housing at the said manipulation temperature, and become(s) relatively straightened on withdrawal into the housing at the said temperature.Preferably the invention provides such a device or apparatus which is of elongate form for surgical manipulation of matter within a living body, and which has the manipulator means at its distal end with the metallic member(s) having pseudoelasticity at the temperature to be encountered within that body, and wherein the actuating means is operable from the proximal end of the device.
