A system generates a navigation space and a virtual space including a calibration phantom including a protrusion pair or a single protrusion based images. The system also identifies sets of coordinates in the virtual space based on an imaging device projection intersecting the protrusion pair or the single protrusion and determines an optimal set of coordinates in the virtual space based on a first event in which the imaging device projection intersects the midpoint of each protrusion of the protrusion pair or based on a second event in which the imaging device projection intersects a tip portion of the single protrusion. The system further calibrates a first coordinate system associated with the virtual space with respect to a second coordinate system associated with the navigation space in response to the first event and based on the optimal set of coordinates.
A system or method may include receiving first data about an environment from a first imaging device (704), receiving second data about the environment from a second imaging device (708), where a perspective of the environment from the second imaging device is different from a perspective of the environment from the first imaging device, identifying at least one common spatial point in the environment using both the first data and the second data (712), and performing a registration process for the first imaging device and/or the second imaging device using the at least one common spatial point (716).
An implantable apparatus (100) and methods thereof. The implantable apparatus (100) includes a body (110) defining a distal end region (112) extending along a distal end region axis (111). The body (110) is configured to be inserted into cardiac tissue of a patient's heart at a target site. The implantable apparatus (100) also includes a plurality of markers (120) located along at least a portion of an outer surface of the distal end region (112) of the body (110). The plurality of markers (120) define a first configuration when located within the cardiac tissue and a second configuration when not located within the cardiac tissue. The first configuration is different than the second configuration.

TOOLS AND ASSEMBLIES THEREOF FOR IMPLANTABLE MEDICAL DEVICES
A tool has an outer assembly, which includes a deployment tube, extending around, and moveable with respect to an inner assembly of the tool; the inner assembly includes a single pull wire and a distal member configured to engage an end of an implantable medical device. The deployment tube includes an articulating segment located just proximal to an enlarged distal-most portion, which contains the device and the distal member. Relatively soft and stiff sections of a composite sidewall define the articulating segment and extend alongside one another, such that, when the pull wire is actuated, the composite sidewall causes bending of the segment in two directions. A handle assembly of the tool includes a control member for the pull wire, and may further include a flushing subassembly that has a connector port located at an end of the handle assembly that is opposite a proximal port of the handle.
Various embodiments of a feedthrough header assembly and a device including such assembly are disclosed. The assembly includes a header having an inner surface and an outer surface; a dielectric substrate having a first major surface and a second major surface, where the second major surface of the dielectric substrate is disposed adjacent to the inner surface of the header; and a patterned conductive layer disposed on the first major surface of the dielectric substrate, where the patterned conductive layer includes a first conductive portion and a second conductive portion electrically isolated from the first conductive portion. The assembly further includes a feedthrough pin electrically connected to the second conductive portion of the patterned conductive layer and disposed within a via that extends through the dielectric substrate and the header. The feedthrough pin extends beyond the outer surface of the header.
A glucose biosensor encasement includes a first membrane and a second membrane. The first membrane has a first interlocking segment. The second membrane has a second interlocking segment cooperating with the first interlocking segment of the first membrane to provide a cavity between the first membrane and the second membrane configured to receive a glucose sensor. At least one of the first membrane and the second membrane comprises a semi-permeable portion configured to regulate diffusion characteristics of glucose through the membrane to realize a sensitivity for a sensor in the cavity. A method is also provided.

The elongated trocar body is insertable through the mapping spacer and cannula. In a first orientation of the trocar relative to the mapping spacer, the proximal handle is configured to abut the first and second uprights to inhibit extension of the distal cutting tip from the proximal base beyond an initial position. In a second orientation of the trocar, the proximal handle is slidable through the slot to enable extension of the distal cutting tip distally towards an extended position.
