Drug delivery articles, resident articles, and retrieval systems e.g., for gram-level dosing, are generally provided. In some embodiments, the articles are configured for transesophageal administration, transesophageal retrieval, and/or gastric retention to/in a subject. In certain embodiments, the article includes dimensions configured for transesophageal administration with a gastric resident system. In some cases, the article may be configured to control drug release e.g., with zero-order drug kinetics with no potential for burst release for weeks to months. In some embodiments, the articles described herein comprise biocompatible materials and/or are safe for gastric retention. In certain embodiments, the article includes dimensions configured for transesophageal retrieval. In some cases, the articles described herein may comprise relatively large doses of drug (e.g., greater than or equal to 1 gram).

A fluid management system including a pass-through fluid volume measurement system to provide continuous measurement of fluid returned from a surgical site during transit to a waste collection system. The pass-through fluid volume measurement system eliminates the need to physically replace full fluid collection containers during the medical procedure with new, empty fluid collection containers.

The present invention relates to a device for the extraction of body fluid by suction, comprising a pump (2) with a pump housing (4) that comprises a suction opening (31), a container (6) with a container housing (8) that surrounds a reservoir (10) for storing the extracted body fluid and comprises an interface (84) in a container housing wall (82) for the communication between the suction opening (31) and the reservoir (10), a suction line port (74) that is connectable to a suction line (6) for the extraction of body fluid by suction, which is provided with a cover element covering the coupling device to improve the cleanliness and/or for the formation of functional surfaces for securing the suction line and/or releasing the coupling device.

A catheter assembly may include a catheter adapter, which may include a distal end, a proximal end, and a lumen extending through the distal end and the proximal end of the catheter adapter. The catheter assembly may also include a catheter extending from the distal end of the catheter adapter. The distal tip of the catheter may include a magnetic material. A method of repositioning the distal tip of the catheter may include inserting the distal tip of the catheter into a blood vessel. The method may include attaching another magnetic material to skin, and the distal tip of the catheter may move toward the other magnetic material. At least one of the magnetic material and the other magnetic material may include a magnet. A kit may include the catheter assembly and/or the other magnetic material.

A suction catheter assembly structured to be movably positioned within a lumen of the body including an elongated base having a channel extending interiorly along the length thereof and further structured to connect the channel to a source of negative pressure. A tip is fixedly or removably connected to a distal end of said base and includes an inlet port and a flow path disposed in fluid communication with the channel. A viewing structure is connected to and movable with the base and is oriented relative thereto to define a line of sight providing observation of a path of travel of said base within the body lumen or medical tubing and is disposed laterally outward from at least a majority of a length of said flow path and the inlet port in substantially aligned, parallel relation to a central axis of said channel.

A centrifugal separation device of a blood component collection system, which is one form of a biological component collection system, performs a pressure release step of stopping a collection and returning pump at the end of a returning operation, and releasing a positive pressure inside a filter structural member, a clamp closure step of closing an inlet flow passage and an outlet flow passage of the filter structural member, and a collection operation starting step of starting a subsequent collection operation.

A method for capturing dislodged vegetative growth during a surgical procedure is provided. The method includes maneuvering, into a circulatory system, a first cannula having a distal end and an opposing proximal end, such that the first cannula is positioned to capture the vegetative growth en bloc. A second cannula is positioned in fluid communication with the first cannula, such that a distal end of the second cannula is situated in spaced relation to the distal end of the first cannula. A suction force is provided through the distal end of the first cannula so as to capture the vegetative growth. Fluid removed by the suction force is reinfused through the distal end of the second cannula. Subsequent to becoming dislodged, the vegetative growth is captured by the first cannula. A method for capturing a vegetative growth during removal of a pacemaker lead is also provided.

A urethral catheter. A cavity is formed at the head end of the urethral catheter, and an internal span of the cavity is greater than that of an opening. A check device (2) located at the front end of a guide core (5) is received in the cavity, and the check device (2) is a guide core (5) that can be retracted into a guide core catheter (4) and can move within the guide core catheter (4). The guide core (5) can expand outward after moving out of the guide core catheter (4). The span of the top of the expanded guide core (5) is greater than the outer diameter of the opening of the cavity at the head end of the urethral catheter. The urethral catheter eliminates a guide extension inserted inside the urethral catheter, and avoids any structural parts provided in the front end of the urethral catheter, and no accessory device is provided at the inner side of the catheter wall of the conventional urethral catheter, so that the internal urination cross-sectional area of the urethral catheter is the same as the area of the inner holes of the urethral catheter, thereby greatly increasing the urine output of the urethral catheter and greatly reducing the injection resistance of a lubricant.

A surgical system comprising a catheter comprising an irrigation tube, a suction tube, an occlusion balloon disposed about the irrigation tube and suction tube, and a console in operative communication with the irrigation tube and the suction tube. The surgical system also comprising a remote operations unit in communication with the console via a connector, wherein an input to the remote operations unit is communicated to the console, which in turn acts to operate the irrigation tube and suction tube in a manner corresponding to the input.

A mask is disclosed that has a gas outlet which is quiet and provides for a diffused outlet flow of gases. The outlet is preferably a slot formed between a hollow body and cover over said hollow body. The mask also preferably extends and seals under a user's chin in use.
