  • APPARATUS AND METHODS FOR TREATING RHINITIS
    Publication number: 20190083157
    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.

  • Apparatus and methods for positioning and securing anchors
    Patent number: 10172608
    Abstract: Apparatus and methods for positioning and securing anchors are disclosed herein. The anchors are adapted to be delivered and implanted into or upon tissue, particularly tissue within the gastrointestinal system of a patient. The anchor is adapted to slide uni-directionally over suture such that a tissue plication may be cinched between anchors. A locking mechanism, either within the anchor itself or positioned proximally of the anchor, may allow for the uni-directional translation of the anchor while enabling the anchor to be locked onto the suture if the anchor is pulled, pushed, or otherwise urged in the opposite direction along the suture. This uni-directional anchor locking mechanism facilitates cinching of the tissue plication between the anchors, and it may be utilized in one or several anchors in cinching a tissue fold.

  • Apparatus and method for treating rhinitis
    Patent number: 10159538
    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.

  • APPARATUS FOR MANIPULATING AND SECURING TISSUE
    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.

  • SYSTEMS AND METHODS FOR LOCATING BLOOD VESSELS IN THE TREATMENT OF RHINITIS
    Publication number: 20180344411
    Abstract: Apparatus and methods for treating and monitoring conditions such as rhinitis are disclosed herein. The technology utilizes ultrasound scans to identify target treatment sites, and monitor the treatment of a patient undergoing a treatment. The treatment may be an ablation treatment of a nasal nerve, for example the PNN for the treatment of nasal conditions, such as rhinitis. The ultrasound scans are performed within the nasal cavity with an ultrasound probe or a combined ultrasound and ablation probe and may use Doppler, A-mode, B-mode, M-mode or other ultrasound and non-ultrasound modalities to detect and monitor the target treatment sites.

  • Integral electrode placement and connection systems
    Patent number: 10111705
    Abstract: Electrode placement and connection systems are described which allow for the electrical connection and maintenance of one or more electrodes positioned on a substrate which is subjected to a variety of mechanical stresses. Electrodes may also be formed on flexible circuit assemblies integrated within or along the hood. The circuit assemblies may also provide structural support to the hood during delivery and/or deployment. Such a system may include an imaging hood having an aperture through which transparent fluid is flowed and one or more electrodes positioned along or about the hood. As the hood is configured between a low-profile and opened configuration, these electrodes may remain electrically coupled despite the mechanical stresses subjected to the electrodes and the connections thereto.

  • Visualization apparatus for transseptal access
    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.
