A stent is formed of at least a cobalt-based alloy. The cobalt-based alloy may include 10-35 weight % metal member selected from the group consisting of platinum (Pt), gold (Au), iridium (Ir), osmium (Os), rhenium (Re), tungsten (W), palladium (Pd), tantalum (Ta), and combinations thereof; 16-21 weight % chromium (Cr); 9-12 weight % molybdenum (Mo); 0-25 weight % nickel (Ni); and balance cobalt (Co). The cobalt-based alloy may be a thin outer shell of a hollow stent. The cobalt-based alloy may be used to form at least one of an inner core and an outer shell of a core-shell structure of a stent. The cobalt-based alloy may be used to form an end of a wire for forming a stent.


A machined or molded hinge design, for use with a delivery device, which allows for controlled deflection of a large diameter catheter. With embodiments in which the delivery device is employed to implant a prosthetic heart valve, deflection of the catheter allows for central alignment of the delivery system in the native annulus during deployment of the bioprosthesis.


A method and medical device for adjusting a blanking period that includes sensing cardiac signals from a plurality of electrodes, the plurality of electrodes forming a plurality of sensing vectors, determining whether to adjust a blanking period during a first operating state, advancing from the first operating state to a second operating state in response to the sensed cardiac signals, determining, while in the second operating state, whether the blanking period was adjusted while in the first operating state, and adjusting the blanking period while in the second operating state in response to the blanking period being adjusted while in the first operating state.


Implantable medical electrical leads having electrodes arranged such that a defibrillation coil electrode and a pace/sense electrode(s) are concurrently positioned substantially over the ventricle when implanted as described. The leads include an elongated lead body having a distal portion and a proximal end, a connector at the proximal end of the lead body, a defibrillation electrode located along the distal portion of the lead body, wherein the defibrillation electrode includes a first electrode segment and a second electrode segment proximal to the first electrode segment by a distance. The leads may include at least one pace/sense electrode, which in some instances, is located between the first defibrillation electrode segment and the second defibrillation electrode segment.

A method and device for implanting a medical lead. The device includes an elongate shaft defining a major longitudinal axis and including a proximal end and a distal end. A necked portion coupled to and extending from the distal end is included, the necked portion defines a first thickness and a substantially planar surface, the necked portion being at least resiliently movable in a direction normal to the major longitudinal axis. A tip disposed at the distal end of the necked portion is included, the tip defining a second thickness greater than the first thickness

Overvoltage protection circuitry configured to protect internal integrated circuits within an implantable device in the presence of a high voltage event such as defibrillation or electrocautery. The circuitry allows for an internal node to rise above the voltage level of the high voltage event to insure that an overvoltage protection element is triggered, even if the voltage level of the high voltage event is below the voltage trigger level of the overvoltage protection element.

Various embodiments of a nuclear radiation particle power converter and method of forming such power converter (10) are disclosed. In one or more embodiments, the power converter can include first and second electrodes, a three-dimensional current collector disposed between the first (12) and second (20) electrodes and electrically coupled to the first electrode, and a charge carrier separator (40) disposed on at least a portion of a surface of the three-dimensional current collector (30). The power converter can also include a hole conductor layer (50) disposed on at least a portion of the charge carrier separator and electrically coupled to the second electrode, and nuclear radiation-emitting material (60) disposed such that at least one nuclear radiation particle emitted by the nuclear radiation- emitting material is incident upon the charge carrier separator.


A method and medical device for determining sensing vectors that includes sensing cardiac signals from a plurality of electrodes, the plurality of electrodes forming a plurality of sensing vectors, determining a sensing vector metric in response to the sensed cardiac signals, determining a morphology metric associated with a morphology of the sensed cardiac signals, determining vector selection metrics in response to the determined sensing vector metric and the determined morphology setting, and selecting a sensing vector of the plurality of sensing vectors in response to the determined vector selection metrics.


A method of calibrating a blood glucose sensor is disclosed comprising: defining an electrochemical impedance spectroscopy (ElS)-based sensor status vector (V) for each one of a plurality of sensor current (Isig)-blood glucose (BG) pairs; monitoring the status vectors for the plurality of Isig-BG pairs over time; detecting when there is a difference between a first status vector for a first Isig-BG pair and a subsequent status vector for a subsequent Isig-BG pair, said first Isig-BG pair having assigned thereto a first offset value; and if a magnitude of said difference is larger than a predetermined threshold, assigning a dynamic offset value for said subsequent Isig-BG pair that is different from said first offset value so as to maintain a substantially linear relationship between said subsequent Isig and said subsequent BG. Optionally, for each Isig-BG pair, the elements of the sensor status vector can include 1kHz real impedance, 1kHz imaginary impedance, Nyquist slope, and Nyquist R square. Alternatively, for each Isig-BG pair, the sensor status vector can include impedance and Nyquist slope as elements of the vector, or 1kHz real impedance, 1kHz imaginary impedance, or Nyquist slope as an element of the vector.
