  • Publication number: 20190343373
    Abstract: A system for visualizing a tissue region of interest comprises a deployment catheter defining at least one lumen therethrough and a hood projecting distally from the deployment catheter. The hood defines an open area that is in fluid communication with the at least one lumen. The system also comprises a delivery catheter sized to extend through the lumen. The delivery catheter includes a distal portion extendable distally from the deployment catheter and into the open area defined by the hood. The distal portion extends distally from the deployment catheter is articulatable within the open area.

  • Patent number: 10470643
    Abstract: A computer implemented method comprises activating a control mechanism on a catheter handle in a first direction with respect to a user to steer a distal end of a catheter within a body in a second direction while the catheter handle is in a first rotational position. The control mechanism includes a first indicator associated with the first direction. The computer implemented method also includes obtaining an image from the distal end of the catheter of a tissue region of interest within the body and calibrating a first rotational motion of the catheter handle with a rotational motion of the image. With the catheter handle in a second rotational position that is different than the first rotational position, the control mechanism activated in the first direction with respect to the user moves the distal end of the catheter in the second direction.

  • Patent number: 10441136
    Abstract: A method of treatment comprises intravascularly securing an anchor extending from an anchor member at least partially within a vessel lumen such that blood flows unobstructed through or past the anchor. While the anchor is secured, a distance of the anchor member, between the anchor and a barrier or membrane projecting distally from a deployment catheter, is adjusted such that an open area defined by the barrier or membrane is placed against or adjacent to a portion of a patient tissue. Adjusting the distance of the anchor member comprises moving the deployment catheter distally with respect to the anchor member. The method also comprises displacing blood with a transparent fluid from the open area, and while the anchor is secured, articulating the barrier or membrane circumferentially around the anchor. The method also includes treating the tissue while visualizing through the transparent fluid.

  • Patent number: 10390685
    Abstract: A system comprises a deployment catheter defining at least one lumen and a hood projecting distally from the deployment catheter and defining an open area. The open area is in direct fluid communication with the at least one lumen. The system also comprises an elongate channel directly coupled to the hood such that the elongate channel terminates distally into the open area. The elongate channel extends proximally from an outer surface of the hood and is bounded proximally at a proximal pocket surface. The system also comprises an imaging element. The imaging element is sized to pass into the elongated channel at a distal end of the elongate channel. Proximal movement within the elongated channel is restricted by the proximal pocket surface. The system also comprises a control member extending within the elongate channel and through the proximal pocket surface for moving the imaging element through the elongate channel.

  • Patent number: 10335131
    Abstract: A method of inhibiting tissue migration comprises positioning an open area of a hood against or adjacent to a tissue region. The method also comprises displacing an opaque fluid with a transparent fluid from the open area. The method includes engaging a portion of the tissue region within the open area via an end effector advanced through the open area and which grasps onto the portion. The end effector includes a tapered section, tapered along its entire length, through which a lumen extends. The tapered section includes threads extending from a surface of the tapered section in a direction orthogonal to the longitudinal axis. The tissue region is pierced while displacing the opaque fluid with the transparent fluid through the distal opening of the hood and while maintaining engagement of the portion of the tissue region such that distal movement of the tissue is inhibited.

  • Publication number: 20180344501
    Abstract: Apparatus for manipulating and securing tissue are described herein. In creating tissue folds within the body of a patient, a tissue manipulation assembly may generally have an elongate tubular member, an engagement member slidably disposed through the tubular member and a distal end adapted to engage tissue via a helical member, tissue stabilizing members positioned at the tubular member distal end which are adapted to stabilize tissue therebetween, and a delivery tube pivotable about the tissue stabilizer. The stabilizing members can be adapted to become angled relative to a longitudinal axis of the elongate tubular member. Moreover, one or all the articulation controls and functions can be integrated into a singular handle assembly connectable to the tissue manipulation assembly via a rigid or flexible tubular body.

  • Patent number: 10064540
    Abstract: Visualization apparatus and methods for transseptal access are described herein where intravascular access across a septal wall is facilitated via devices which provide for direct visual viewing of tissue area. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to the tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid can be pumped into the imaging hood until the fluid displaces any blood leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. Any number of therapeutic tools or a guidewire can be passed through the catheter and into the imaging hood for crossing the septal wall and passing the guidewire or instruments therethrough.

  • Patent number: 10004388
    Abstract: Coronary sinus cannulation apparatus and methods relating to tissue visualization catheters that can locate and/or cannulate a morphological feature within a body lumen, such as the coronary sinus, are described. Such devices can also perform a variety of therapeutic tissue treatments under direct in vivo visualization thereafter. Moreover, such apparatus and methods may also be utilized with guidewires to facilitate delivery into the coronary sinus to eliminate repositioning of the device and/or repeating an entire sequence of operations, consequently improving procedure effectiveness and reducing procedure time.

  • Publication number: 20170071460
    Abstract: A method of inhibiting a flow of a purging fluid from a tissue visualization device comprises positioning an imaging hood attached to a distal end of a flexible elongate shaft in proximity to a tissue region to be visualized The method also comprises introducing the purging fluid into an inflation member suspended within an open area of the imaging hood. The inflation member includes at least one aperture on a proximal portion of the inflation member. The method also comprises inflating the inflation member to a partially inflated state in which the inflation member is circumferentially separated from an inner surface of the hood to form an annular flow path for the purging fluid from the at least one aperture, between the inner surface of the hood and the inflation member, and into fluid communication with an environment external to the hood.

  • Patent number: 9526401
    Abstract: Flow reduction hood systems are described which facilitate the visualization of tissue regions through a clear fluid. Such a system may include an imaging hood having one or more layers covering the distal opening and defines one or more apertures which control the infusion and controlled retention of the clearing fluid into the hood. In this manner, the amount of clearing fluid may be limited and the clarity of the imaging of the underlying tissue through the fluid within the hood may be maintained for relatively longer periods of time by inhibiting, delaying, or preventing the infusion of surrounding blood into the viewing field. The aperture size may be controlled to decrease or increase through selective inflation of the membrane or other mechanisms.
