Abstract: A steerable medical device includes an elongate tool, and a handle, and a steering assembly. The handle is mounted to the tool and has a handle body and a knob that is rotatable with respect to the handle body. The steering assembly includes at least a first spool housed within the handle body and coupled to the knob, and at least first control wire windable about the first spool and coupled to the tool. Rotation of the knob with respect to the handle body drives rotation of the first spool, rotation of the first spool cause winding of the first control wire about the first spool to tension the control wire, and tensioning of the control wire causes deflection of the tool.

Abstract: A steerable medical device includes a handle having a handle body and a first control assembly that is movable with respect to the handle body. A first cam is housed within the handle body and is coupled to the control assembly. Movement of the control assembly with respect to the handle body drives rotation of the cam with respect to the handle body. A first slider is housed within the handle body and is coupled to the cam. Rotation of the cam drives translation of the slider within the handle body. An elongate tool extends from the handle. A first control wire is coupled between the first slider and the tool. Translation of the first slider causes tensioning of the control wire, and tensioning of the control wire causes deflection of the tool.

Abstract: A handle for a medical device includes a handle body and a knob that is rotatable with respect to the handle body. A first gear is associated with the knob. A slide assembly is housed within the handle body or the knob. The slide assembly includes a first lead screw. A second gear is associated with the slide assembly. A third gear is housed within the handle body or the knob and is coupled between the first gear and the second gear. Rotation of the knob drives rotation of the first gear, rotation of the first gear drives rotation of the third gear, rotation of the third gear drives rotation of the second gear, and rotation of the second gear drives rotation of the lead screw.

Abstract: A system of medical devices includes an introducer and a needle. The introducer has an introducer proximal portion and an introducer distal portion. The introducer proximal portion defines an introducer proximal end and the introducer distal portion defines an introducer distal end. The introducer has a lumen extending therethrough from the introducer proximal end to the introducer distal end. The needle is receivable in the introducer and has a needle proximal portion and a needle distal portion. The needle proximal portion defines a needle proximal end and the needle distal portion defines a sharp needle distal end. The needle proximal portion comprises at least a first depth marker that, when aligned with a feature of the introducer, indicates a first relative position of the needle distal end and the introducer distal end.

Abstract: A method and apparatus are disclosed for a device for creating a puncture in a tissue. The puncturing device comprising an elongate member having a puncturing portion at the distal tip. The puncturing device further includes at least one inflatable feature positioned around the outer circumference and at a distal portion of the elongate member. The puncturing device includes a lumen extending from a proximal end of the elongate member to the inflatable feature. The inflatable feature is in fluid communication with the lumen and can be inflated to dilate the puncture in the tissue or anchor the puncturing device in a heart structure.

Abstract: A perforation device for use in medical procedures includes an elongate shaft extending between a proximal portion defining a proximal end and a distal portion defining a distal end. The shaft includes an electrode assembly at the distal end, a wire extending between the proximal end and the electrode assembly, and an electrically resistive coating cladding the wire between the proximal end and the electrode assembly. A first coating clads the electrically resistive coating along the proximal portion. The first coating is relatively stiff. A second coating clads the electrically resistive coating along at least a first section of the distal portion. The second coating is relatively flexible.

Abstract: Apparatus for use with an electroanatomical mapping system, an elongated needle assembly having a distal energy emitter configured to be detectable by the electroanatomical mapping system, an energy-delivery assembly having at least one sensor configured to receive, at least in part, the distal energy emitter of the elongated needle assembly in such a way that the distal energy emitter and said at least one sensor are movable relative to each other. The apparatus includes a signal-interface assembly. The signal-interface assembly includes a signal-input section configured to be signal connectable to said at least one sensor of the energy-delivery assembly. A signal-output section is configured to be signal connectable to an input section of the electroanatomical mapping system.

Abstract: A method and apparatus are disclosed for creating a puncture in a tissue. The assembly includes a puncturing device having a distal tip configured to deliver energy to the tissue, creating the puncture. The puncturing device further includes a marker positioned along the puncturing device. The assembly further includes a dilator which has a lumen extending from a proximal portion to a distal portion and configured to receive the puncturing device. The dilator further comprises a sensor positioned along a length of the dilator. When the marker and the sensor are aligned, energy is delivered to the distal tip of the puncturing device.

Abstract: A primary elongated medical assembly is configured to be positioned in, and movable along, a patient. A secondary elongated medical assembly is configured to be positioned in, and movable along, the patient. The primary elongated medical assembly has a primary sensor device. The secondary elongated medical assembly has a secondary sensor device. The primary elongated medical assembly and the secondary elongated medical assembly are each configured to be movable relative to each other; this is done in such a way that the primary sensor device and the secondary sensor device are movable relative to each other.

Abstract: A system for carrying out a medical procedure includes a medical device for advancing into a patient's body towards an anatomical volume, and a medical imaging system. The medical imaging system is configured to generate a graphical representation of the anatomical volume and to provide in the graphical representation real-time information about the position of the medical device within the anatomical volume. The medical imaging system includes a safety module configured to select one or more regions within the graphical representation for designation as a non-target region, and to monitor the position of the medical device within the anatomical volume and take a safety action if the position of the medical device within the anatomical volume corresponds to one of the non-target regions.
