Abstract: A guidewire, consisting of a flexible biocompatible tube, having a tube distal end, the tube containing an internal lumen and being configured to be inserted into an orifice of a body of a living subject. A planar resilient strip is inserted into the internal lumen, the strip having a strip proximal end and a strip distal end fixed to the tube distal end. A coil spring is fixed to the strip proximal end so that an axis of symmetry of the coil is coplanar with the strip, the coil spring containing a coil lumen. A wire is threaded through the coil lumen and has a termination fixed to the strip distal end, so that pulling on the wire causes the strip and the tube to bend.

Abstract: A registration device, including a wand, a light guide passing through the wand, and a position sensor fixed to the wand. A light source outputs a modulated beam of light into a light guide proximal end, so that the light is emitted from a light guide distal end toward a surface in proximity to a wand distal tip. A detector receives, from the light guide proximal end, light reflected from the surface into the light guide distal end, and outputs a signal indicative of the reflected light intensity. A processor computes a distance from the distal tip of the wand to the surface by extracting a phase difference between the output beam and the reflected light from the signal, and computes a position of the surface in a sensor frame of reference responsively to the computed distance and the location of the distal tip found from the position sensor.

Abstract: A medical tool includes a handle, a tubular member, and a bendable shape memory element (SHE). The tubular member is attached to and extends from the handle and is configured to be inserted into an orifice of a patient. The tubular member has a distal-end section that is configured to be bent so as to perform a medical procedure in the orifice. The bendable shape memory element (SHE) is coupled to the distal-end section of the tubular member, wherein the SHE is configured to straighten when heated into a preformed shape, thereby straightening the distal-end section.

Abstract: A method for manufacturing a breast implant includes producing a silicone shell of the breast implant by rotating a mold (30) containing a silicone material to evenly spread the silicone material over an inner surface of the mold. Subsequently, an elastic filler material including silicone foam is formed in the shell by (i) injecting into the mold a mixture comprising silicone gel and gas bubbles and (ii) rotating the mold to homogenize the mixture.

Abstract: A medical instrument includes a shaft, multiple flexible spines and multiple electrodes. The shaft is configured for insertion into a body of a patient. The multiple flexible spines have respective first ends that are connected to a distal end of the shaft and respective second ends that are free-standing and unanchored. The spines are bent proximally such that the second ends are more proximal than the first ends. Each of the flexible spines includes a tensile layer configured to cause the flexible spine to bend proximally. The multiple electrodes are disposed over the flexible spines.

Abstract: An implant includes a hollow container and a valve. The hollow container is configured to be implanted in an organ of a patient, and to contain filling material. The valve has first and second position sensors coupled thereto, and is configured to allow passage of the filling material to and from the container, so as to vary a volume of the implant.

Abstract: A medical instrument includes a shaft, an expandable balloon and a collapsing set of splines. The shaft is configured for insertion into a body of a patient. The expandable balloon is coupled to a distal end of the shaft. The collapsing set of splines is made at least partially from a shape-memory material having a collapsed pre-formed shape that collapses the balloon.

Abstract: An apparatus, including a pump body having an internal shaft, and a piston disposed within the shaft and having a piston head that includes a first ferromagnetic element. The apparatus also includes a motor coupled to drive a reciprocal longitudinal motion of the piston within the shaft, and a pump chamber configured to be removably attached to the pump body and having a rigid wall defining a fluid inlet, a fluid outlet, and an aperture. The apparatus additionally includes a flexible diaphragm fixed across the aperture and having a second ferromagnetic element, which engages the first ferromagnetic element when the pump chamber is attached to the pump body so that the reciprocal longitudinal motion of the piston causes alternating stretching and contraction of the flexible diaphragm, thereby modifying a volume of the pump chamber.
