    Abstract: A guide device establishes a guide passage through a guide tube, through which an operative tool can be deployed into an interior body region for use. A steering assembly, in use, deflects or bends the distal end region of the guide tube, so that the operative tool can be placed in a desired orientation with respect to tissue. The steering assembly is desirable configured for single handed operation by the clinician. The steering assembly is also desirably configured to provide a mechanical advantage sufficient to translate relatively small increments of clinician control into relatively larger increments of guide tube deflection. In one arrangement, the steering assembly includes a rack and pinion linkage system. In another arrangement, the steering assembly includes a pivoting lever system.

  • Patent number: 10252031
    Abstract: A medical device has a distal member with a configuration that can be changed by means of a control handle with a control assembly employing a rotational cam, a shaft, and a pulley, where the rotational cam is rotationally mounted on a portion of the control handle for rotation by a user. The rotational cam operates on the shaft to move it proximally or distally depending on the direction of rotation which in turn rotates the pulley to draw or release a puller wire to change the configuration of the distal member of the medical device. The shaft is oriented along a diameter of the control handle. The shaft has two ends which extends through two axial guide slots in the portion of the control handle to sit two opposing helical tracks formed on inner surface of the rotational cam. The guide slots are parallel with the longitudinal axis of the control handle and therefore maintain the shaft's diametrical orientation as the rotational cam is rotated to move the shaft proximal or distally.

  • Patent number: 10085863
    Abstract: A guide wire may include a core shaft and an external coil body covering a distal portion of the core shaft. The external coil body includes a first coil portion and a second coil portion that is distal to the first coil portion. An outside diameter of the second coil portion is smaller than an outside diameter of the first coil portion. Similarly, the guide wire may include a core shaft, a first external coil body, and a second external coil body. An outside diameter of the second external coil body is smaller than an outside diameter of the first external coil body. The external coil body or first and second external coil bodies enable the performance of a pushing-out operation and a drawing-in operation of the stent; yet, the flexibility of the guide wire is maintained.

  • Patent number: 10071228
    Abstract: Preformed guiding stylet for introducing a septal lead in contact with the septum or other intra-corporal device in contact with body tissue. This stylet includes a flexible wire to be introduced by its distal end in a central lumen of the lead, and a control handle. The wire is elastically deformable in bending and has sufficient rigidity in torsion to enable transmission by the handle rotation of a rotational movement over the entire length of the wire. Unstressed, the wire comprises successively in its distal part a first curvilinear portion a first straight portion a second curvilinear portion and optionally a second straight portion. The first and second curvilinear portions extend in respective planes making an angle between them defining a dihedral which axis comprises the first straight portion. The total length of the first curvilinear portion coincides with the anatomical curvature of the venous system.

  • Patent number: 10058235
    Abstract: The present invention relates to a steerable catheter device and method of using the same comprising a catheter body having a distal section. The distal section of the catheter body has an inner lumen, and one or more steering lumen radially offset from the inner lumen. The steering lumen comprise a first end having a first diameter and a second end having a second diameter smaller than the first diameter. A fluid source is in fluid communication with the steering lumen for supplying fluid thereto to radially distend the first end of the steering lumen such that the catheter body bends away from the steering lumen. In some cases, a vacuum is supplied to an opposite lumen to further assist bending of the catheter body. The inner lumen may include a porous material that is utilized to clean an instrument, such as an imaging device, movably disposed in the inner lumen.

  • Patent number: 10039904
    Abstract: A guide wire includes a core shaft, a coil body which covers the core shaft, and a coating film which covers the coil body. Portions of the coating film are disposed between adjacent coils of coil body, and gaps are formed between the coils and the portions of the coating film disposed between the adjacent coils. Due to this configuration, the coating the film can be easily bent, and thus the coil body may easily bend. As a result, it is possible to ensure lubricity of guide wire within the blood vessel while also enabling the guide wire to follow the shape of the blood vessel in which it is inserted.

  • Patent number: RE47379
    Abstract: A coaxial guide catheter to be passed through guide catheter having a first lumen, for use with interventional cardiology devices that are insertable into a branch artery that branches off from a main artery. The coaxial guide catheter is extended through the lumen of the guide catheter and beyond the distal end of the guide catheter and inserted into the branch artery. The device assists in resisting axial and shear forces exerted by an interventional cardiology device passed through the second lumen and beyond the flexible distal tip portion that would otherwise tend to dislodge the guide catheter from the branch artery.
