  • Patent number: 10398503
    Abstract: A method is provided, including transvascularly inserting a guidewire into a right atrium of a subject. Apparatus is provided that includes (a) a catheter, and (b) a hollow needle disposed within a lumen of the catheter, the hollow needle including a proximal portion and a distal portion that is more flexible than the proximal portion. The apparatus is passed into the right atrium by passing the needle over the guidewire. Following the passing of the apparatus into the right atrium, the guidewire is partially withdrawn into the needle, while keeping a distal end of the guidewire within the needle and in a body of the subject. Thereafter, a hole is formed through an interatrial septum of the subject with the needle. Other embodiments are also described.

  • Patent number: 10350002
    Abstract: An electrode assembly for a catheter system has a longitudinal axis, a proximal end and a distal end. Multiple struts extend coextensively with each other from the proximal end to the distal end of the electrode assembly. Each strut carries an electrode spaced longitudinally from the proximal end of the electrode assembly. The longitudinal spacing of one electrode from the proximal end of the electrode assembly is different from the longitudinal spacing of another electrode from the proximal end of the electrode assembly. The electrode assembly is configurable between a collapsed configuration and an expanded configuration, with the electrodes being transversely spaced from the longitudinal axis of the electrode assembly a greater distance in the expanded configuration than in the collapsed configuration. In the expanded configuration, the electrodes are transversely spaced from the longitudinal axis of the electrode assembly approximately the same distance.

  • Patent number: 10307200
    Abstract: Apparatus and methods for treating conditions such as rhinitis are disclosed herein where a distal end of a probe shaft is introduced through the nasal cavity where the distal end has an end effector with a first configuration having a low-profile which is shaped to manipulate tissue within the nasal cavity. The distal end may be positioned into proximity of a tissue region having a post nasal nerve associated with a middle or inferior nasal turbinate. Once suitably positioned, the distal end may be reconfigured from the first configuration to a second configuration which is shaped to contact and follow the tissue region and the post nasal nerve may then be ablated via the distal end. Ablation may be performed using various mechanisms, such as cryotherapy, and optionally under direct visualization.

  • Patent number: 5672179
    Abstract: An intubation device and a method of intubating a patient with an endotracheal tube is disclosed. The device comprises a housing and a flexible, tubular sheath having one end connected to the housing and a free end extending away from it. The sheath, which is adapted to fit within the endotracheal tube, also has a special light at the end of the sheath's free end for selectively providing illumination. In use, the sheath is inserted into the endotracheal tube until the light is at the end of the distal end of the tube. A clamp on the intubation device then clamps the endotracheal tube to the housing to prevent relative movement between the tube and the sheath. A tube stop is then slid along the sheath into abutting contact with the proximal end of the endotracheal tube to identify the location on the sheath corresponding to the proximal end of the tube. When the tube is properly positioned in the patient, the light will create a distinct glow visible to an observer in the area of the sternal notch.

  • Patent number: 5507739
    Abstract: A dual wavelength laser is disclosed for use in dental therapeutic applications. The dual wavelength laser includes a laser cavity in which a laser crystal is disposed and preferably the laser crystal is an Nd:YAG laser, which, upon excitation, lases at two different wavelengths, each of which has a different gain. A shutter, or alternatively an optical filter, is selectively disposed within the optical path of the laser crystal whereupon the higher gain wavelength is selectively suppressed. Thus, with the shutter or optical filter removed from the optical path, the laser lases at its higher gain wavelength. Conversely, with the shutter or filter positioned within the optical path, the higher gain wavelength is effectively suppressed so that the laser crystal lases at the lower gain wavelength.

  • Patent number: 5383874
    Abstract: A catheter carries a functional component, like an ablating electrode, having a predetermined operating characteristic. The catheter also electronically retains an identification code that uniquely identifies the predetermined operating characteristic. The catheter is capable of transmitting the identification code to an external reader in response to a predetermined prompt. An associated apparatus, like an ablating energy source, reads the identification code and compares it to predetermined operating criteria. The apparatus will not permit interaction with the functional catheter component, if the identification code indicates that the functional characteristics of the catheter are not suited for the intended interaction. The catheter can also store usage information, to prevent reuse.
