Автор: Christopher Houghton, Eric Sugalski, Erik Holverson
Принадлежит: Individual

A crossbar lever of a surgical tool has a bridge portion which extends forward and a transverse portion. The bridge portion is retained between the second and third fingers of the surgeon's hand, and this retention establishes greater control and stability of the surgical tool. The crossbar lever pivots relative to a handgrip of a handle assembly and a shaft assembly extends from the handle assembly. Tissue contacting or manipulating devices such as jaws are located at the forward end of the shaft assembly. The surgical tool is particularly useful in performing minimally invasive surgical procedures.

Method and apparatus for increasing blood flow through an obstructed blood vessel

Номер: US20120041459A1
Автор: David Fiorella, Henry Woo
Принадлежит: CLEVELAND CLINIC FOUNDATION

A method of increasing blood flow through an obstructed blood vessel includes providing an expandable member substantially made of a mesh having a plurality of interstices. The expandable member is inserted into the blood vessel, positioned within the blood vessel with the proximal member end upstream of the distal member end and the member body located radially adjacent at least a portion of an obstruction, and expanded to bring at least a portion of the member body into contact with the obstruction. An outward radial force is exerted on the obstruction to dislodge at least one fragment from the obstruction and to enhance blood flow through the blood vessel past the obstruction. The at least one fragment is passed through at least one interstice of the member body in the radial direction, and is selectively retained within the expandable member.

Автор: Andrew H. Cragg, David A. Ferrera, John Fulkerson
Принадлежит: Mindframe LLC

Systems, methods, and devices for the treatment of acute ischemic stroke that provide immediate blood flow restoration to a vessel occluded by a clot and, after reestablishing blood flow, address the clot itself. Immediate blood flow restoration advantageously can facilitate natural lysis of the clot and also can reduce or obviate the concern for distal embolization due to fragmentation of the clot. Several embodiments of the invention provide for progressive, or modular, treatment based upon the nature of the clot. For example, the progressive treatment can include immediate restoration of blood flow, in-situ clot management, and/or clot removal depending on the particular circumstances of the treatment. The in-situ clot management can include, for example, lysis, maceration, and/or removal.

Tongue cleaner and method for manufacturing the same

Номер: US20120095486A1
Автор: Michio Tanaka

A tongue cleaner in which a gap between a concavely curved surface formed in a cleaner head and a sheet for covering the same is minimized or eliminated, decreasing the likeliness of tongue coating to accumulate therebetween. A head is provided with a first sheet on a face of the head formed with a concavely curved surface. The sheet is fixed to a lateral side of the head, enabling the sheet opposed to the concavely curved surface to be slidable thereon. After arranging a sheet material on the concavely curved surface with the head being in a single-piece state as a component of the tongue cleaner, the sheet material is pressed against the concavely curved surface by means of a lower mold and an upper mold.

The present invention provides a cannula guide tube; and a kit with the cannula guide tube, a flexible transparent cannula or a transparent catheter with an inflatable balloon at the catheter end, and an exploratory device. The kit is for irrigation, suction and washing out purulent or liquid discharges from bacteria infected sinuses. First, the exploratory device is used to find the entrance orifice to a sinus; second, the cannula guide tube is positioned in the sinus orifice entrance; and third, the flexible transparent cannula or the transparent catheter is inserted through the cannula guide tube into the sinus. The flexible transparent cannula or transparent catheter is used to suction the purulent or liquid discharge and to irrigate and wash out the sinus. The cannula guide tube has an opening before the tube end, wherein the opening allows seeing the flexible transparent cannula or transparent catheter inside the tube and the flow of purulent or liquid discharge suctioned from the sinus, as the purulent discharge flows throughout the flexible transparent cannula or the transparent catheter.

A surgical tool having an elongate shaft, with a directional operative element at its distal end, is provided with a mechanism to rotate the shaft and the operative element about a longitudinal axis shaft. This allows the operative element to be aligned with an element of tissue without excessive hand movement by the user. In a preferred version, the mechanism is electrically powered and is regulated to produce smooth, controlled, accurate motion between selected rotational positions. The mechanism may include a linear magnetic motor drive to move a drive element longitudinally along the tool. This drive element is engaged with a helical formation on a drive shaft, such that longitudinal motion of the drive element is converted to rotational motion of the drive shaft, and of the shaft and operative element, to which the shaft is mounted.

Clot disruption and dissolution are achieved using a catheter having the ability to infuse a thrombolytic agent, aspirate clot and fluid, and allow passage of a guidewire. Optionally, the catheter may also include a mechanical agitator for further disrupt clot in the presence of the thrombolytic agent. A flow resistor in the catheter provides for infusion and/or aspiration to be concentrated primarily at a clot treatment area in a blood vessel while also providing optional infusion and/or aspiration distal to the treatment area. In some embodiments, infusion, aspiration and guidewire passage occur through a common lumen. The thrombolytic agent, such as tPA, streptokinase, or urokinase, is directly released into the clot at the point where the agitator is engaging the clot. In this way, the thrombolytic activity of the agent is enhanced and the dissolution of the clot is improved.
