Abstract: In some examples, a catheter includes an elongated body defining an inner lumen and comprising an expandable member disposed at a distal portion of the elongated body, and a rotatable cutting tool located within an inner lumen of the elongated body, the rotatable cutting tool configured to segment a thrombus into smaller pieces while an aspiration force pulls the thrombus proximally into the inner lumen. In some examples, the catheter further comprises an intermediate structure oriented radially between the rotatable cutting tool and an interior surface of the elongated body, the intermediate structure configured to prevent the cutting tool from contacting the interior surface of the elongated body. In some examples, a stopper is configured to limit movement of the cutting tool distally past a distal end of the expandable member.

Abstract: A clot removal device for removing a clot from a body vessel is presented. The device can facilitate clot retrieval by expanding in such a way as to engage the clot over a significant surface area. The clot can have at least one firm portion and at least one soft portion. At least one firm portion of the clot can be pinched by a proximal portion of the device while at least one soft portion of the clot can be retained by the distal portion of the device upon extraction. However, dislodgement and removal of the clot can cause softer portions the clot to shear or break, resulting in small floating fragments of clot in the vessel no longer attached to the main clot. This device can also capture and retain sheared or expanded distal portions of the clot upon removal of the clot from a vessel.

Abstract: The present disclosure provides a surgical shunt assembly tool that provides a more efficacious grip on the catheter tubes and prevent the tip of the catheter from buckling while the catheter is pushed onto the tip of the valve during installation of shunts during CSF shunt surgery. The tool includes standard handles such as used in a shodded mosquito tool having a clamping jaw integrated into the distal end section of the handle. The distal jaw includes two forcep jaw sections each having a proximal end integrally formed with a distal end of a distal end arm section of one of the two handle arms, and a distal end section extending away from the distal end arm section. The distal end sections of the forcep jaw sections are cylindrically shaped such that when the forcep jaw is closed by bringing the two forcep jaw sections together, a cylinder is formed having a diameter substantially equal to a diameter of a catheter tube to be attached to a shunt valve tip.

For example, a ligation band can be provide with a substantially ring-shaped elastic body that has a first tissue-contacting surface, a second tissue-contacting surface opposite the first tissue-contacting surface, and an aperture that extends therethrough. At least one of the tissue-contacting surfaces can have a plurality of protrusions that define an interlinking web-pattern with a plurality of recesses.

Abstract: Disclosed embodiments include apparatuses, systems, and methods for guiding a needle to facilitate suturing, such as in surgical anastomosis. In an illustrative embodiment, an apparatus includes at least one guide member configured to extend from a suturing mechanism that is configured to revolve a helically-shaped needle around an axis while the needle is advanced around an object to be sutured. A guide track is configured to be positioned around the object and to guide the suturing mechanism in an articulated path around the object. The guide track defines at least one guide channel configured to receive the guide member, where the at least one guide channel is configured to direct movement of the guide member to cause the suturing mechanism to pivot to realign the axis to be tangential to the curved guide track.

Abstract: A wound closure system includes a device having a first main body and a second main body. Each of the first main body and the second main body has an adhesive backing. The first main body is coupled to the second main body by an adjustable connector. The adjustable connector is permitted to move in a single direction. In the event of an injury, the first and second main bodies are placed on opposite sides of a wound and are then pulled together, thereby sealing the wound.

Abstract: Sheathed cutting device. An exemplary device for discreetly piercing a skin of a patient can comprise a body having a proximal end and a distal end, a cutting member attached to a plunger, the cutting member and the plunger positioned at least partially within the body, and a biasing member configured to bias the cutting member to an initial position whereby the cutting member is positioned fully within the body, wherein the plunger is slidable into the proximal end of the body, causing the cutting member to extend from the distal end of the body.

A kit may include two plugs, which may be used singly or in combination with each other and are independently adjustable/rotatable. A method for reducing nasal discomfort or improving nasal functions by diverting channeled airflow in a nostril is also disclosed.
