Systems and methods for the intravascular treatment of clot material within a blood vessel of a human patient are disclosed herein. A method in accordance with embodiments of the present technology can include, for example, engaging an interventional device of a catheter system with clot material in a blood vessel and withdrawing the interventional device and the portion of the clot material through a guide catheter. In some embodiments, the catheter system can include an attachment/valve member coupled to a proximal portion of the guide catheter, and the method can include unsealing the attachment/valve member to facilitate withdrawing the interventional device through the attachment/valve member without significant retention of clot material within the attachment/valve member. The method can further include resealing and aspirating the guide catheter before advancing another interventional device to the clot material to again engage and remove clot material from the blood vessel.

Disclosed herein are apparatuses, systems, kits, and methods for treating skin, such as skin tightening or for treating diseases, disorders, and conditions that would benefit from tissue area or volume reduction, skin restoration, skin tightening, skin lifting, and/or skin repositioning and/or for generally improving skin function or appearance (e.g., the removal of unwanted skin features or irregularities such as sebaceous glands, sweat glands, hair follicles, necrosis, and fibrosis). Such apparatuses, systems, kits, and methods comprise an apparatus having a handheld main body and a detachably attachable tip comprising one or more needles.

A robotic system includes an instrument including an elongate shaft, a robotic manipulator configured to manipulate the elongate shaft of the instrument, and control circuitry communicatively coupled to the robotic manipulator and configured to determine a first estimated position of at least a portion of the elongate shaft of the instrument based at least in part on robotic command data, determine a second estimated position of the at least a portion of the elongate shaft of the instrument based at least in part on position sensor data, compare the first estimated position and the second estimated position, and generate a third estimated position based at least in part on the comparison of the first estimated position to the second estimated position.

An actuation system for actuating concentric tubes of a concentric-tube robot. The actuation system is configured to actuate the concentric tubes from radially to one side of the concentric tubes.

The disclosure provides for an isovolumetric pump system for the removal of a thrombus and a method of use thereof. The isovolumetric pump system includes at least one inflow container connected to an output of the treatment region, at least one outflow container connected to an input of the treatment region, and a drawbar connecting the inflow container and the outflow container. As the drawbar is drawn back, the same quantity of fluid is drawn from the treatment region into the inflow container and injected into the treatment region from the outflow container.

A medical device is adapted for use in assisting with mechanical thrombectomy. The medical device may include a housing that is adapted to be held within a user's hand and a pump that is secured within the housing. A fluid inlet is adapted to receive fluid that is pulled towards the pump and is fluidly coupled with the pump. A fluid outlet is adapted to expel fluid away from the pump and is fluidly coupled with the pump. As the pump is operated by the user, fluid is alternatively pulled into the fluid inlet and expelled through the fluid outlet. In some cases, the fluid may be blood or other bodily fluids.

Disclosed is a surgical instrument for cataract eye surgery. The instrument generally includes a handpiece that delivers sub-ultrasonic and ultrasonic vibrations in either a steady-state emulsification mode or with on-off pulses that dynamically drives a hollow needle in either a pulsed fragmentation mode or a pulsed emulsification mode. The pulsed fragmentation mode is efficient at cutting lens tissue and the pulsed emulsification mode is efficient and emulsifying the cut lands tissue. The pulsed modes manage heat buildup from becoming excessive in the eye during the cataract surgery. While in the pulsed fragmentation mode, the hollow needle is never given the chance to vibrate at an established resonant frequency of the handpiece due to the short on-off period. In contrast, the pulsed emulsification mode has a long enough on-off period to permit an ultrasonic resonant frequency in the handpiece to develop thereby driving the hollow needle at a higher energy than the pulsed fragmentation mode.

A rotatable surgical instrument, system, and method includes an outer tubular member and an inner tubular member contained, at least in part, within the outer tubular member and configured to rotate relative to the outer tubular member. A distal tip is coupled to and configured to rotate with the inner tubular member, the distal tip forming a channel around a portion of the distal tip. A bearing is rotatably positioned within the channel, wherein the channel inhibits radial and axial movement of the bearing, with respect to the distal tip, along a major axis of the outer tubular member and inner tubular member, and wherein the bearing is configured to inhibit deflection of the distal tip from the major axis.

An arthroscopic or other surgical cutter has features which facilitate fabrication by ceramic molding. The arthroscopic cutter includes a cutter body having a longitudinal axis and a window, an interior channel, and a plurality of cutting edges extending radially outwardly from an outer surface thereof. The features include non-helical, longitudinally aligned cutting edges, controlled thicknesses of the cutting edges, controlled heights of the cutting edges, controlled areas of the windows, controlled diameters of the internal channels, controlled rake angles of the cutting edges, and other parameters.

Described are methods, systems, devices for facilitation of intraluminal medical procedures within the neurovasculature. A catheter advancement device includes a flexible elongate body having a proximal end, a distal end, and a single lumen extending therebetween. The flexible elongate body has a proximal segment, an intermediate segment, and a tip segment. The proximal segment includes a hypotube coated with a polymer. The intermediate segment includes an unreinforced polymer having a durometer of no more than 72D. The tip segment is formed of a polymer different from the intermediate segment and has a durometer of no more than about 35D and a length of at least 5 cm. The tip segment has a tapered portion that tapers distally from a first outer diameter to a second outer diameter over a length of between 1 and 3 cm.
