摘要： An apparatus for precision pen height control which includes a dispensing member, a fluid dispensing system, a vertical position sensing system, and a vertical position controller. The fluid dispensing system is in fluid communication with an opening in the dispensing member via a tubular member. A vertical position sensing system, which includes a diffraction grating and a sensor, is engaged to the tubular member. The sensor is positioned adjacent the diffraction grating. The diffraction grating is engaged to a vertical support, which is engaged to the tubular member. The sensor produces a vertical position signal based upon the position of the vertical support. The vertical position controller is engaged to the vertical position sensing system, and receives a control signal generated from the vertical position signal. The vertical position controller produces and applies vertical forces to the vertical support in response to the control signal.

摘要： Annuloplasty rings and methods for inserting annuloplasty rings are herein disclosed. The annuloplasty ring has a ring shell and a plurality of anchoring fasteners for anchoring the ring shell to adjacent hear tissue. To maintain the shape of the annuloplasty ring upon attachment of the ring to the patient's heart, a hardening polymer is inserted into the ring shell, which is permitted to cure, thereby providing support for the annuloplasty ring and the patient's heart valve.

摘要： A catheter is configured to access a renal artery. A lumen of the catheter's shaft is dimensioned to receive a flexible actuation member which extends between the shaft's proximal and distal ends. The actuation member is moveable within the lumen and subject to elastic deformation, friction, and/or whip along its length. A flexible support member is coupled to a distal end of the actuation member and extendible beyond a distal tip of the shaft. An RF ablation electrode at a distal end of the support member is configured to ablated perivascular renal nerve tissue. A position converter at the distal end of the shaft is configured to convert movement of the actuation member into one or both of controlled rotational and axial movement of the support member and electrode to one of a multiplicity of stable circumferential positions substantially free of elastic deformation, friction, and/or whip impacting actuation member movement.

摘要： In one illustrative example, a device for sealing an opening in a vessel wall and/or tissue tract may include an anchor, a filament, a plug, and a knot. The anchor may be configured to be disposed adjacent to an interior surface of the vessel wall adjacent the opening in the vessel wall. The filament may have a distal end coupled to the anchor and may be configured to extend proximally through the vessel opening and/or tissue tract. The plug may be disposed about at least a portion of the filament member. The knot may be disposed about the filament proximal of the plug and may be configured to move over the filament and secure the plug relative to the anchor. The knot may be independent of the filament member.

摘要： A flexible catheter includes a magnetically permeable element provided at its distal end. The magnetically permeable element is configured for placement within the renal artery. External coils, positionable on anterior and posterior portions of a patient in proximity to the renal artery, are coupled to a generator which energizes the external coils to create a high-frequency oscillating magnetic field in body tissue between the external coils including the renal artery and perivascular renal nerve tissue. The magnetically permeable element serves to concentrate the magnetic field in a region near the renal artery. The concentrated magnetic field induces high frequency electric current sufficient to ablate the perivascular renal nerve tissue proximate the renal artery. A cooling arrangement can be provided at the catheter's distal end and configured to provide cooling to the renal artery during ablation of the perivascular renal nerve tissue.

摘要： Techniques are described that allow intravascular ultrasound (“IVUS”) imaging of patient tissue, e.g., a blood vessel wall, to be performed at one or more angles selected by a clinician, for example. In one example, a method includes receiving user input, via interaction with a user interface, that defines a range of angles through which a scan will be performed, determining, based on the received user input, at least one current value to be applied to at least one lead of a stator of a motor, controlling application of the at least one current to the at least one lead of the stator in order to rotate a rotor of the motor through the range of angles, and through the range of angles, receiving and processing electrical signals from at least one transducer to form at least one image.
