  • Patent number: 11730551
    Abstract: A steerable medical instrument, such as a catheter or endoscope, comprises a tubular body having non-steerable section and steerable sections arranged from a proximal end to a distal end thereof. The tubular body defines a tool channel and a plurality of wire conduits formed along the wall of the tubular body. The steerable section includes wire-guiding members arranged in lengthwise direction alternated with void regions. A control wire arranged in a first conduit within the wall of the tubular body is connected to an actuator and transfers an actuating force to bend the steerable section. An electrical cable arranged along the wall of the tubular body has strain relief elements. The strain relief elements are portions of the cable arranged in at least one void region and configured to freely move within the void regions to provide strain relief to the electrical cable when the tubular body bends.

  • Publication number: 20220126060
    Abstract: A catheter sheath comprises: a central lumen extrusion having an inner layer defining a central lumen, a reinforcing structure surrounding the inner layer, and an outer layer surrounding the reinforcing structure; a plurality of rings are arranged on the outer layer of the central lumen extrusion at a predetermined distance from each other in a distal section of the sheath; and an outer jacket encloses the rings and central lumen extrusion. The reinforcing structure includes one or more of a braid, a coil, and a laser-cut tube embedded between the inner layer and the outer layer; the central lumen extrusion is bonded with an adhesive or laser welded or pressure fit to one or more of the rings. The reinforcing structure is offset towards the inner or the outer surface; and the rings have chamfered or beveled or rounded inner edges.

  • Patent number: 10315015
    Abstract: A medical device having an elongate support structure and an inflatable balloon including a first-end portion secured to the support structure at a first location, a second-end portion secured to the support structure at a second location distal to the first location, and a middle-body portion. The first-end portion has a wall thickness greater than a wall thickness of the middle-body portion; the balloon defines a sealed interior through which the support structure extends. The balloon being stretch-mounted to the support structure in tension relative to the support structure; the balloon is formed in a diamond-like configuration that transitions to a substantially spherical configuration when the balloon is inflated to a inflation pressure that is at least about ten percent greater than atmospheric pressure, such that when inflated to the inflation pressure and anchored in an anatomical body region, resists movement of the support structure relative to the balloon.

  • Patent number: 9687331
    Abstract: A slidable locking device for fixing a position of a medical device, includes a housing having a passageway therethrough and an actuator coupled to the housing movable between a locked position and an unlocked position. The actuator includes at least two arms extending therefrom that are operatively coupled with at least two engaging members disposed within the housing, each engaging member having a slot configured to receive a respective arm of the actuator, the engaging members being biased towards the housing passageway, wherein the engaging members are disposed toward the housing passageway when the actuator is in the locked position, and the engaging members are disposed away from the housing passageway when the actuator is in the unlocked position.
