Described herein are systems, devices, and methods for methods for autologous blood transfusion. For example, an apparatus may comprise a fluid conduit configured to receive a volume of fluid from a patient and a container fluidically coupled to the fluid conduit. The container may define a reservoir configured to receive the volume of fluid from the fluid conduit. The apparatus may include a vacuum conduit couplable to a vacuum source, a vent configured to vent air into the reservoir, and at least one valve configured to couple the reservoir to the vacuum conduit to generate negative pressure within the reservoir such that the volume of fluid is drawn into the reservoir, and decouple the reservoir from the vacuum conduit while coupling the reservoir to the vent such that air is vented into the reservoir at an average rate that prevents turbulent movement of the volume of fluid within the reservoir.

Blood transfusion for thrombectomy devices, and systems and methods thereof

Described herein are systems, devices, and methods for aspiration and mechanical thrombectomy. In some embodiments, a thrombectomy device for removing a thrombus from a vessel can include a handle assembly, a vacuum source, an aspiration catheter with an expandable distal portion, and a flexible shaft configured to rotate within the aspiration catheter.

Thrombectomy systems and devices with aspiration, and methods of use thereof

Described herein are systems, devices, and methods for removing material from patient vasculature. In some embodiments, an aspiration device may include a sheath and a catheter slidably disposed within the sheath and defining a lumen. The catheter may include a distal end portion and an elongate portion, the distal end portion being disposable adjacent to a clot, the elongate portion being couplable to a vacuum source that is configured to apply a negative pressure to the lumen to draw the clot into the distal end portion. The distal end portion may include a plurality of sections, each of the plurality of sections having a different cut pattern.

Systems, devices, and methods for aspiration, including expandable structures and rotatable shafts

According to exemplary embodiments of the present disclosure, a system for collection and analysis of cells from a body lumen of a patient may include a diagnostics device including a tube having a distal end and a proximal end and a balloon having a first end coupled to the distal end of the tube. The balloon may be disposed in the tube in a first, inverted position and movable to a second, everted position. A push wire may have a distal end coupled to a second end of the balloon. The balloon may be movable from the first inverted position to the second everted position by actuation of the push wire. One or more receptacles may be included for processing a balloon sample. The system may further include at least one of a sample preparation fluid, a sample preservation liquid, or both. The sample may be preparable for cytological analysis.

Cell collection and preparation devices and methods

A drug or agent coated balloon having a length which is adjustable in vivo is described herein. The balloon is configured to be coated or coatable with one or more drugs where the coating may be applied prior to advancement into a patient body or prior to balloon expansion within the patient body. The length of the expandable portion of the balloon is adjustable to approximate a length of the tissue region to be treated. Moreover, the drug-coated balloon may be used alone or it may be utilized to deploy luminal prostheses having one or more linked or otherwise coupled segments.

Adjustable-length drug delivery balloon

Methods and devices for performing minimally invasive procedures useful for Fallopian tube diagnostics are disclosed. In at least one embodiment, the proximal os of the Fallopian tube is accessed via an intrauterine approach; an introducer catheter is advanced to cannulate and form a fluid tight seal with the proximal os of the Fallopian tube; a second catheter inside the introducer catheter is provided to track the length of the Fallopian tube and out into the abdominal cavity; a balloon at the end of the second catheter is inflated and the second catheter is retracted until the balloon seals the distal os of the Fallopian tube; irrigation is performed substantially over the length of the Fallopian tube; and the irrigation fluid is recovered for cytology or cell analysis.

Methods and devices for fallopian tube diagnostics

A system for removing a kidney stone from a ureter may include: an elongate, flexible, outer shaft having a distal end configured to be advanced into the ureter and a proximal end; an elongate, flexible, inner shaft extending through at least part of the outer shaft; an expandable stone retention member extending through at least part of the inner shaft and moveable along the longitudinal axis relative to the inner shaft; an elongate, flexible camera positioned coaxially within the retention member shaft, such that a distal end of the camera is located at or near a distal end of the inner shaft; and a handle coupled with the proximal end of the outer shaft, a proximal end of the inner shaft, and a proximal end of the retention member shaft.

Device for removing kidney stones

The present disclosure generally relates to devices, systems, and methods for Fallopian tube diagnostics. In some embodiments, a tube may have a distal end, and a balloon may be coupled to the distal end of the tube. The balloon may be disposed in the tube in a first, inverted position and movable to a second, everted position. The balloon may be extendable a distance distal of the tube distal end such that a surface of the balloon is contactable with an inner surface of the Fallopian tube. A push wire may have a distal end coupled to a second end of the balloon. The balloon may be movable from the first inverted position to the second everted position by actuation of the push wire. The surface of the balloon may include a plurality of surface features for collection of a tissue sample of the inner surface of the Fallopian tube.

Systems, methods, and devices for fallopian tube diagnostics

The present disclosure generally relates to devices, systems, and methods for Fallopian tube diagnostics. In some embodiments a tube may have a distal end, and a balloon may have a first end coupled to the distal end of the tube. The balloon may be disposed in the tube in a first, inverted position, may be movable to a second, everted position, and may be extendable a distance distal of the tube. An extending portion may have a proximal end coupled to a second end of the balloon. The extending portion may be disposed within the balloon in the first inverted position, and may be extendable from the second end of the balloon in the second everted position.

Methods and devices for Fallopian tube diagnostics

A device for removing an obstruction from a lumen in a human or animal subject may include an inflatable balloon. The inflatable balloon may include a proximal tapered portion having a proximal taper angle, a central portion, and a distal tapered portion having a distal taper angle that is greater than the proximal taper angle. The balloon may also include at least one eversion feature on the proximal tapered portion and/or the distal tapered portion. The eversion feature may facilitate preferential eversion of the distal tapered portion into an inside of the balloon without the proximal tapered portion collapsing. Preferential eversion of the distal tapered portion may be provided by the differences in the distal and proximal taper angles and by one or more of a number of different types of eversion features.
