  • Publication number: 20200305693
    Abstract: A system for visualizing a tissue region of interest comprises a deployment catheter defining a lumen and a hood coupled to and extending distally from the deployment catheter. The hood has a low-profile configuration within a delivery sheath and a deployed configuration when extended distally of the delivery sheath. The hood in the deployed configuration defines an open area in fluid communication with the lumen. A distal portion of the deployment catheter extends into the open area. The system also comprises an imaging element coupled to an imager support member. When the hood is in the deployed configuration, the imaging element is configured to extend distally of the distal portion of the deployment catheter while the imager support member extends within the deployment catheter.

  • Patent number: 10772492
    Abstract: A method of inhibiting flow of a purging fluid from a device comprises positioning an imaging hood in proximity to a tissue region to be visualized. The imaging hood includes a distal membrane which defines a main aperture. The imaging hood and the distal membrane define an open area. The method also comprises introducing the purging fluid into a proximal portion of the open area. The proximal portion is bounded by a proximal membrane including a plurality of apertures. The method also comprises pressurizing the proximal membrane with the purging fluid to a partially extended state in which the purging fluid flows through the plurality of apertures and through the main aperture. The method also comprises pressurizing the proximal membrane with the purging fluid to a blocking extended state in which the proximal membrane obstructs the main aperture to block the flow of the purging fluid through the main aperture.

  • Publication number: 20200054200
    Abstract: The delivery of biological compounds to ischemic and/or infarcted tissue are described herein where 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 a region of 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, such as saline, can be pumped into the imaging hood until the fluid displaces any blood, thereby leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. Additionally, any number of therapeutic tools can also be passed through the deployment catheter and into the imaging hood for performing any number of procedures on the tissue for identifying, locating, and/or accessing ischemic and/or infarcted tissue.

  • Publication number: 20200038134
    Abstract: Devices and methods for treating rhinitis are described where the devices are configured to ablate a single nerve branch or multiple nerve branches of the posterior nasal nerves located within the nasal cavity. A surgical probe may be inserted into the sub-mucosal space of a lateral nasal wall and advanced towards a posterior nasal nerve associated with a middle nasal turbinate or an inferior nasal turbinate into a position proximate to the posterior nasal nerve where neuroablation of the posterior nasal nerve may be performed with the surgical probe. The probe device may utilize a visible light beacon that provides trans-illumination of the sub-mucosal tissue or an expandable structure disposed in the vicinity of the distal end of the probe shaft to enable the surgeon to visualize the sub-mucosal position of the distal end of the surgical probe from inside the nasal cavity using, e.g., an endoscope.

  • Patent number: 10512498
    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: 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.
