  • Patent number: 10894145
    Abstract: A steerable catheter having a hub with a control feature includes a semi-rigid catheter with the hub attached at the proximal end. The distal end of the catheter includes a distal tip and a flexible portion adjacent the distal tip. The catheter includes a working channel, and further includes a channel through which a tension member or wire extends to the distal tip. Tension in the wire causes the distal tip to deflect and be steered. The hub includes a fixed member attached to the catheter, an inner member that moves axially relative to the fixed member, and an outer member that rotates relative to the inner member and the fixed member. Rotation of the outer member results in translation of the inner member, which is attached to the tension member and provides for controlled steering of the distal tip.

    Abstract: The present disclosure describes an angioplasty balloon catheter having a retractable sheath and a flexible tip attached to the distal end of the sheath. The flexible tip is made of an elastomeric plastic that is capable of returning to its original shape after being expanded multiple times. The tip allows for the sheath to be retractable and the balloon inflated multiple times to treat or expand different locations within the vessel. Because the tip returns to its original shape each time, the tip is less likely to damage the vessel wall when the sheath is repositioned in the vessel, and also is easier to retract through a guide-catheter.

  • Patent number: 10016576
    Abstract: A catheter for use in a patient's heart, especially for mapping a tubular region of the heart, has a catheter body, a deflectable intermediate section and a distal a mapping assembly that has a generally circular portion adapted to sit on or in a tubular region of the heart. A control handle of the catheter allows for single-handed manipulation of various control mechanisms that can deflect the intermediate section and contract the mapping assembly by means of a deflection control assembly and a linear control assembly. The deflection control assembly has a deflection arm and a rocker member. The linear control assembly has a linear control member, an inner rotational member and a cam. A pair of puller members are responsive to the deflection control assembly to bi-directionally deflect the intermediate section. A third puller member is responsive to the linear control assembly to contract the generally circular portion of the mapping assembly.

  • Patent number: 10016187
    Abstract: A surgical instrument comprises a steering mechanism. The steering mechanism comprises a handle at a proximal end of the surgical instrument. The handle includes a plurality of controls for controlling a movement of the surgical instrument. The steering mechanism also comprises a hub that rotatably mates with the handle and a housing positioned about the hub. The handle, the housing, and the hub communicate with each other to provide at least a first degree of freedom and a second degree of freedom. An articulation region is at a distal end of the surgical instrument. A movement of the steering mechanism handle in one and only one of the first or second degrees of freedom relative to at least one of the housing or the hub translates to a movement of the articulation region in a single plane of motion.

  • Patent number: 9833221
    Abstract: A method for bringing an IVUS and an OCT image into register. In one embodiment, the method includes obtaining an IVUS image of an area of a lumen; obtaining an OCT image of the same area of the lumen; determining the same asymmetry in each of the IVUS and OCT images; and overlaying the IVUS and OCT images and rotating them with respect to one another until the asymmetry in each of the IVUS and OCT images are in register, and determining the angle of rotation that resulted in the registration. In another aspect, the invention relates to a probe for OCT and IVUS imaging. In one embodiment, the probe includes a sheath having a first end and a second end defining a lumen; a marker that is opaque to light and ultrasound located between the first end and second end; and an IVUS/OCT probe head positioned within the sheath.

  • Patent number: 9795765
    Abstract: A catheter assembly including a tapered steering spine having a varying stiffness along an axial length. The tapered steering spine is tailored to provide increasing flexibility from proximal to distal in a way that makes the bend radius more uniform along the length of the steering section. In one embodiment, the tapered steering spine includes structures on adjacent rings that engage with each other when the steering section is flexed to limit the minimum bend radius to a predetermined minimum and which enhances the torsional rigidity of the steering section regardless of the degree of flexure of the steering section. The limited bend radius can prevent excessive bending of components such as fiber optics. The enhanced torsional rigidity can negate the need for torque braid in the section of the catheter shaft that surrounds the tapered steering spine.

  • Patent number: 9717523
    Abstract: Disclosed is a pericardiocentesis needle component (10), comprising a guide wire (13) and a puncture needle (12). The guide wire (13) extends into and through the puncture needle (12), and the guide wire (13) comprises a bent section (32) at the distal end and a straight section at the proximal end. The bent section (32) at the distal end is formed by bending the guide wire (13), and the end of the bent section is a pointed-shape structure. The guide wire (13) is made of a highly elastic material. The pointed end rotates at least 90 degrees within a range of no more than 3 mm starting from the pointed end at the bent section (32) of the guide wire. The pericardiocentesis needle component (10) of the present invention is less likely to damage a heart during a pericardiocentesis procedure.

  • Patent number: 9687631
    Abstract: A steering handle for a catheter. The steering handle includes a thumb knob arrangement for driving a cam assembly that in turn actuates a pull wire or pull wires. In some embodiments, the cam assembly includes a set of dual pins that actuate the pull wire in a quasi-linear relationship between cam rotation and axial displacement of the wire. In certain embodiments, the second set of dual pins imparts a reverse action on a second pull wire, also in quasi-linear fashion. That is, when one wire is released by the cam assembly, the other wire is taken in by the cam assembly. In various embodiments, the quasi-linear action can cause release of more pull wire than is taken in, thereby helping prevent the released pull wire to act as an unwanted counter force to the actuated pull wire.
