Abstract
Abstract The invention provides a method of using an apparatus for manipulating matter in a confined or inaccessible space, comprising providing an apparatus having manipulator means at least partly constructed of one or more bent or twisted elongate shape memory alloy members having pseudoelasticity at the intended manipulation temperature, and a hollow housing or cannula capable of holding at least the shape memory alloy member(s) in a relatively straightened state, and actuating means for extending the shape memory alloy member(s) from the housing to manipulate matter within the space and for withdrawing the shape memory alloy member(s) into the housing, the arrangement being such that the shape-memory alloy 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 manipulation temperature, and become(s) relatively straightened on withdrawal into the housing at the temperature.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
142 words
A method of manipulating matter in a space in a mammalian body, the method comprising the steps of: a) providing a manipulating device comprising i) at least one bent or twisted elongated shape memory alloy member having pseudoelasticity at the mammalian body temperature, and ii) a barrier material spanning each alloy member, the barrier material being impermeable to the matter manipulated; iii) an elongated housing defining a bore sized to pseudoelastically deform each alloy member in a relatively straightened state, and b) extending each member from the bore to manipulate matter within the space, each member bend(s) or twist(s) pseudoelastically in a lateral or helical sense to manipulate the matter on extending from the bore at the mammalian body temperature; and c) withdrawing each alloy member into the bore such that each alloy member becomes relatively straightened at the mammalian body temperature.
