The embodiments include an apparatus used in combination with a computer for sensing biopotentials. The apparatus includes a catheter in which there is a plurality of sensing electrodes, a corresponding plurality of local amplifiers, each coupled to one of the plurality of sensing electrodes, a data, control and power circuit coupled to the plurality of local amplifiers, and a photonic device bidirectionally communicating an electrical signal with the data, control and power circuit. An optical fiber optically communicated with the photonic device. The photonic device bidirectionally communicates an optical signal with the optical fiber. An optical interface device provides optical power to the optical fiber and thence to the photonic device and receives optical signals through the optical fiber from the photonic device. The optical interface device bidirectionally communicates an electrical data, control and power signal to the computer.

A medical tool includes, a deflectable distal end, at least a pull wire, and a coupling element. The at least pull wire has a first end coupled to the distal end of the medical tool, and configured to be moved for deflecting the distal end. The coupling element is coupled to a second end of the pull wire and having at least two boreholes configured to receive at least two respective rods traversing therethrough. The coupling element is configured to be moved along a rotation axis of a rotatable element coupled thereto, and the boreholes and the respective rods are configured to prevent rotation of the coupling element.

Disclosed is a method for generating high resolution point cloud data for electro-anatomical mapping comprising receiving sparsely measured point cloud data having a plurality of data points. Surface mesh data comprising mesh points defining triangles on a myocardial surface is generated. The point cloud data is mapped to the surface mesh data. For each point of the surface mesh data that cannot be mapped to the point cloud data because there is a missing data point in point cloud data, an interpolation operation is performed based on the point cloud data within the neighbourhood of the point to generate a value for the missing data point. The interpolation operation is repeated N times. For every repetition, a difference between the value for the missing data point generated from the current iteration and the value for the missing data point generated from the immediately preceding iteration is compared, until the difference is below a threshold.

There is provided a system for cardiac electromagnetic/magnetic catheterization for diagnosing and treating blood vessels of a patient. The system having at least one electromagnetic intraluminal capsule able to force its way through a narrowing blood vessel, the capsule carrying a camera allowing visualization of blood vessels of a patient. There is a portable electromagnetic tip, where the tip pulls the electromagnetic capsule by electromagnetic force, and when the magnetic tip moves along a body of a patient and pulls the intraluminal electromagnetic capsule along with it towards a narrowing blood vessel visualized by the camera, so that the capsule then treats the narrowing site and clears the blood vessel from coronary plaque. In addition working capsule can replace diseased valve in any cardiac position for either temporary or permanent needs.

A urinary catheter insertion alignment device for use by a female patient is disclosed. The urinary catheter insertion alignment device is molded to the patient's vaginal anatomy using impression material while an intermittent urinary catheter is inserted into the urethral orifice. Once the urinary catheter insertion alignment device has hardened, the intermittent urinary catheter is removed therefrom. Thereafter, the urinary catheter insertion alignment device may be fitted to the vaginal anatomy by the patient, which positions the passageway therethrough (formerly occupied by the urinary catheter in place during the molding operation) directly over the urethral orifice. The patient may then easily insert an intermittent urinary catheter (of a size smaller than that used during the molding operation) through the passageway, into the urethral orifice, and into the bladder for drainage of the bladder.

Urinary catheters and methods for preventing bacterial infections.

An intraluminal sensing device includes a catheter or a guidewire with a flexible elongate member that is positioned within a body lumen of a patient. The device also includes a sensor disposed at a distal portion of the flexible elongate member. The sensor obtains medical data associated with the body lumen while the flexible elongate member is positioned within the body lumen. The sensor is an ultrasound transducer, a pressure sensor, a flow sensor, and/or a temperature sensor. The device further includes a radiopaque marker coupled to the flexible elongate member. The radiopaque marker is an ultraviolet (UV) radiation-cured product of a mixture that includes a radiopaque material, an electromagnetic-radiation-curable adhesive, and a photoinitiator. The solution of the mixture is applied directly to the flexible elongate member and UV radiation-cured to form the radiopaque marker. The radiopaque marker is a band extending around a perimeter of the flexible elongate member.

A biostimulator delivery system having a tether cable, is described. A connector can be mounted on the tether cable to connect to a biostimulator. The connector can be a protuberance that lodges within the biostimulator, or a threaded connector that screws into the biostimulator. The tether cable has a stranded cable configuration, including several strands extending about a core strand in a helical direction. The stranded cable structure resists breaking under bending stresses typically seen during a tether mode used during delivery of the biostimulator. The tether cable reliably secures the biostimulator to the delivery system in the tether mode. Other embodiments are also described and claimed.

The Foley Catheter Cap molded from medical grade silicone to provide a stable base for the insertion of an indwelling “Foley” catheter so that tearing of the urethra does not occur. Since the head of a penis contains no sweat glands of any kind, there is no buildup of fluids beneath the Foley Catheter Cap to occur which thereby precludes an environment under the Foley Catheter Cap which could be conducive for infections to grow. Because of this the benefits of a Foley Catheter Cap for male patients required to have an indwelling catheter for extended periods of time greatly outweigh any latent risk while the omission of the proposed Foley Catheter Cap exposes male patients to the potential of the well-documented serious injury and follow-on reconstructive surgery caused by Ventral Erosion of the penis.
