摘要： A microcatheter with a guidewire therein can be steered to target tissue, then the target tissue can be punctured with the guidewire to create a transseptal puncture. The microcatheter can have a diameter substantially smaller than known sheaths which are typically used to guide a needle to a target puncture site in known transseptal puncture treatments. The guidewire can have an atraumatic, electrically conductive distal end that can be electrically energized to puncture the target tissue. Once the guide wire is across, ancillary devices such as a dilator and sheath can be delivered over the guide wire across the transseptal puncture. The microcatheter can include one or more location sensors. A navigation module can use the electrically conductive distal end as a reference electrode to the location sensor(s) of the microcatheter.

摘要： The disclosed technology includes a hemostasis valve assembly comprising an elongate body with a first valve disposed near the proximal end and a second valve disposed near the distal end and spaced apart from the first valve. The first valve can allow a member to extend through the first valve and the second valve can allow the member to extend through the second valve. The elongate body can define a cavity comprising a sloped portion including a first distance between an inner surface of the elongate body and the longitudinal axis near the distal end that is greater than a distance between the inner surface and the longitudinal axis near the proximal end such that a gas is directed along the sloped portion to accumulate at an accumulation region in the cavity near the distal end when a member extends through the first valve.

摘要： Medical apparatus includes a probe with a basket assembly at its distal end, including a plurality of resilient spines with multiple electrodes arrayed along a length of each of the spines. Processing circuitry is configured to acquire a first bipolar electrical signal from the tissue between first and second electrodes at first and second locations along a first spine of the basket assembly, and to acquire a second bipolar electrical signal from the tissue between the first electrode and a third electrode in a third location on a second spine of the basket assembly, and to interpolate, based on the first and second bipolar electrical signals, a vectorial electrical property of the tissue along an axis that passes through the first location and between the second and third locations.

摘要： The disclosed technology includes a fluid evacuation device for a balloon catheter including at least one spine having a curved proximal portion and a straight distal portion extending along a longitudinal axis, a first coupler coupled to the curved proximal portion of the spine to constrain at least one spine to move along the longitudinal axis, and a second coupler attached to the distal portion of the at least one spine so that in a first operational mode, the curved proximal portion of the at least one spine is expanded to a first outer profile and in a second operational mode, the curved proximal portion of the at least one spine is compressed to a smaller outer profile than the first outer profile such that the at least one spine moves the second coupler along the longitudinal axis.

摘要： A dilation instrument (600) includes a body (612) and a shaft assembly (620) extending distally from the body. The shaft assembly includes a malleable guide member (640) and a ball tip (652) positioned at a distal end of the malleable guide member (640). The shaft assembly further includes a position sensor (346) positioned within the ball tip. The position sensor is configured to generate a signal indicating a position of the ball tip in three-dimensional space. The shaft assembly further includes an illuminating feature (344) positioned within the ball tip. The illuminating feature is configured to emit light. The shaft assembly further includes an inflatable balloon (664) positioned proximal to the enlarged tip. The inflatable balloon is configured to dilate a passageway in an ear, nose, or throat of a patient.

摘要： The disclosed technology includes a medical probe comprising a plurality of spine members that form a substantially cylindrical structure. Each spine is stamped from a continuous piece of flat stock and heat-treated to a configuration including a first section extending along a longitudinal axis from a first end to a first bend, a second section extending from the first section curvilinearly with respect to the longitudinal axis and comprising a bifurcation point, and a third section extending along the longitudinal axis from a second bend to a second end so that a proximal portion of the third section is generally parallel to the first section. The second section comprises a continuous leg and a discontinuous leg. The continuous leg extends between the first section and the bifurcation point. The discontinuous leg extends towards the first section and terminates at a termination point between the bifurcation point and the first end.
