  • Patent number: 9788854
    Abstract: A method of removing material from a blood flow lumen includes providing a device having a cutting element and an opening, the cutting element being movable relative to the opening. The method then includes advancing the device through a patient's vascular system to the blood flow lumen. Finally, the method involves moving the cutting element and the opening relative to the blood flow lumen so that a continuous piece of material is severed by the cutting element and directed into the opening as the cutting element and opening move through the blood flow lumen, the continuous piece of severed material being directed into the device for removal from the patient. The method may include providing a device having a rotatable cutter that, in some embodiments, is not parallel to the longitudinal axis of the device, is movable, has retracted and deployed positions, or any combination thereof.

    Abstract: Ultrasound catheter devices and methods provide enhanced disruption of blood vessel obstructions. Generally, an ultrasound catheter includes an elongate flexible catheter body with one or more lumens. An ultrasound transmission member or wire extends longitudinally through the catheter body lumen and, in many embodiments, a guide wire tube also extends through the same lumen. A distal head is fixed to or otherwise mechanically coupled with the distal end of the ultrasound transmission member or wire and is positioned adjacent the distal end of the catheter body. Although the distal end of the catheter body overlaps the distal head, the distal head is not directly affixed to the distal end of the catheter body. Thus, the distal tip may move freely, relative to the distal end of the catheter body when ultrasonic energy is applied through the ultrasound transmission member.

  • Patent number: 9662478
    Abstract: Drainage systems for excess body fluids and associated methods are disclosed herein. A body fluid drainage system in accordance with an embodiment of the present technology, for example, can include a catheter that has an exterior surface, a proximal portion, and a distal portion opposite the proximal portion. The body fluid drainage system can further include a valve device, a pressure sensor, and a controller operatively coupled to the valve device and the pressure sensor. The valve device can include an actuator positioned over the exterior surface of the catheter. The actuator is movable between an open position that allows body fluid flow through the catheter, a closed position that at least substantially obstructs the body fluid flow through the catheter, and intermediate positions that partially obstruct the body fluid flow through the catheter. The controller can change the position of the actuator in response to a predetermined condition of the pressure sensor.

  • Patent number: 9662169
    Abstract: A catheter has at least two irrigated ablation electrodes and a coaxial irrigation tubing to transport fluid to the electrodes by separate and dedicated flow paths. A valve is used to control flow of fluid into the coaxial irrigation tubing by means of a plunger assembly that allows fluid to flow through one lumen of the coaxial irrigation tubing while regulating the flow into the other lumen of the coaxial irrigation tubing in response to the fluid flow rate and pressure applied to the plunger assembly.

  • Patent number: 9649222
    Abstract: In one aspect of the invention, a multi-purpose phacoemulsification needle comprises a needle body disposed about a centerline and has a lumen disposed therein. The lumen has a first cross-sectional area that is normal to the centerline. The needle further comprises a distal tip comprising an arcuate surface and a face with a port therein. The port has a second cross-sectional area in a plane generally parallel to the face and is in fluid communication with an internal cavity that has a third cross-sectional area normal to the centerline, the internal cavity being in fluid communication with the lumen. The needle is configured such that the third cross-sectional area is greater than either the first cross-sectional area or the second cross-sectional area. In another aspect of the invention, the needle comprises a plurality of fins projecting inwardly from the lumen.

  • Patent number: 9636195
    Abstract: An oral hygiene system for cleaning teeth and gums includes a mouthpiece having at least one arcuate channel adapted to receive and surround the teeth. The mouthpiece includes at least two modalities chosen from a mechanical modality, an iontophoretic modality, and a disinfection modality. The mechanical modality brushes the teeth and gums and dislodges food debris, the iontophoretic modality breaks up plaque and tartar buildup, and the disinfection modality removes the food debris, plaque and tartar buildup. A control system coordinates the transmission of modalities, tracks and records utilization, recording completed and failed treatment cycles, and transmits them to a monitoring system. The monitoring system, which links to electronic medical administrating record (eMAR) technology and patient tracking technology (e.g., RFID sensors, electronic tags), facilitates compliance with recommended oral hygiene regimens and review of compliance by medical staff, assisted living staff, and/or caregivers.

  • Patent number: 9636126
    Abstract: A method involves introducing a raking part into a lumen in an ureteral access sheath in which is located calculus, wherein the raking part is introduced into the ureteral access sheath while at least a part of the ureteral access sheath is located in a living body. The raking part is moved in the ureteral access sheath toward the calculus and is positioned beyond the calculus. The lumen in the ureteral access sheath is at least partially occluded by way of the raking part. After at least partially occluding the lumen in the ureteral access sheath by way of the raking part, the raking part is moved along the lumen in the ureteral access sheath in a direction opposite the first direction so that the raking part rakes out the calculus.
