Abstract: A minimally invasive surgical instrument using 3-axis magnetic positioning, system and methods thereof. This invention describes two key ideas that enable the development of a magnetic position system based on integrated anisotropic magnetoresistive (AMR) magnetic field sensors. This achieves the resolution, power and area targets necessary to integrate 3 axes anisotropic magnetoresistance (AMR) sensors along with the Analog Front End integrated circuit (IC) in a 4 mm by 350 um integrated solution for catheter applications. The stringent area and power dissipation requirements are met by development through both system level solutions for higher field strengths and a minimally necessary Analog Front End (AFE) to meet the 1 mm rms resolution requirement in the power dissipation and area budget.

Abstract: An integrated device package sized and shaped to fit in a small space, such as within a body lumen or cavity of a human patient, is disclosed. The integrated device package includes a package substrate and integrated device dies. The first and second integrated device dies are angled relative to one another about the longitudinal axis by a fixed non-parallel angle.

Abstract: According to one configuration, a controller controls use of multiple medical devices at a medical site. For example, a first medical device at the medical site is operable to perform one or more tissue ablation operations; a second medical device at the medical site is operable to perform non-ablation operations (such as tissue monitoring operations). The controller implements a control sequence to control switching between different operational modes including a first mode and a second mode. The first mode and corresponding first windows of time enable the first medical device to perform an ablation operation; the second mode and corresponding windows of time disable the first medical device from performing the ablation operation so that the second medical device operates without interference from the first medical device performing the ablation operation.

Abstract: Various methods and systems are provided to control a probe moving towards fluid held in a container. The probe is moved towards the fluid to take a sample of the fluid in the container. To take a sample, probe is actuated to hit the fluid surface and to pass the fluid surface by a predetermined distance. Capacitive sensing which incorporates the probe itself is used to support an approach engine for controlling the motion of the probe. The approach engine determines the speed of the probe based on capacitance measurements, and in some cases based on position information of the probe. The approach engine ensures the probe hits the surface of the fluid in the container in order to take a sample while ensuring the probe does not hit the bottom of the container.
