Abstract: The present disclosure relates to a drainage catheter and methods of use for providing catheterization procedures, such as during a percutaneous nephrostomy. The drainage catheter includes a body including a first tube segment and a second tube segment connected to one another at a curved end portion to form a continuous body structure. An inner surface of the curved end portion includes one or more drainage openings extending therethrough, with an outer surface of the curved end portion free of drainage openings. The openings are in communication with a lumen that extends through the drainage catheter to provide a pathway for removing fluid from the kidney. The drainage catheter is inserted into the kidney via a first insertion site and exits via a second insertion site.

Abstract: A drainage stent delivery system is disclosed. The system can include a catheter body, a stent member, and a coupling member. The coupling member is configured to selectively couple and decouple the catheter body and the stent member. The coupling member can include a first connector, a second connector, and a telescoping connector. A tab of the first connector is configured to be received by a slot of the second connector when the first and second connectors are coupled. The telescoping connector can displace the tab radially outward to be received by the slot. The tab is biased radially inward when the telescoping connector is displaced. When coupled, the catheter body and the stent member are rotationally fixed.

Abstract: A drainage catheter configured for draining bodily fluid from a patient is disclosed. The drainage catheter may comprise a catheter tube with a drainage lumen and a suture lumen. A suture of the drainage catheter may be disposed within the suture lumen. The suture may be coupled to a distal end of the catheter tube and extend proximally through a hub disposed at the proximal end of the catheter tube.

Abstract: Devices, systems, and methods used to grasp and retrieve a target foreign body or object from a body lumen are disclosed. The devices include a slide actuator, a catheter operably coupled to the slide actuator, and a grasping member in a fixed position relative to the slide actuator. The slide actuator can axially displace the catheter relative to the grasping member to transition the grasping member from an open state to a closed or grasping state. The slide actuator can be locked in the closed state to retrieve the target foreign object from the patient's body.

Abstract: A drainage catheter configured for draining bodily fluid from a patient is disclosed. The drainage catheter may comprise a catheter tube with a drainage lumen.

Abstract: Medical push connectors and systems are provided. A medical push connector can include an engagement member operatively coupled to a release member. The engagement member may releasably couple a medical device to the medical push connector. Medical push connector systems may include one or more medical devices and a medical push connector coupled to, or coupleable to, the one or more medical devices.

Abstract: Devices used to drain fluid are disclosed. The devices may be configured to drain fluid from a body cavity using a vacuum pressure. The devices include a reservoir and a vacuum generating member configured to expand the reservoir and generate a vacuum pressure within the reservoir. The devices can be configured to be shipped in a collapsed state.

Abstract: Catheter exchange systems and methods may use a cutting tool to sever an encrusted catheter. The cutting tool may include a flexible cannula to encompass and move along the encrusted catheter. A sheath may selectively cover the cutting tool. The cutting tool may selectively transition between a first position in which the cutter is within the sheath and a second position in which the cutting tool is extended beyond the sheath to sever a suture of the catheter. A locking stylet may be used to secure the position of the encrusted catheter and remove the encrusted catheter.

Abstract: Expandable introducer systems are provided. An expandable introducer system can include an expandable introducer, an expander, a support member, and/or an exchange dilator. The expandable introducer may be configured to transition from an unexpanded configuration to an expanded configuration. For example, the expander may be displaced through the expandable introducer and transition the expandable introducer from the unexpanded configuration to the expanded configuration. The support member may be disposed within the expandable introducer that is in the expanded configuration to maintain the expandable introducer in the expanded configuration.

Abstract: A drainage stent delivery system is disclosed. The drainage stent delivery system includes a catheter body, a stent member, and a coupling member. In some embodiments the coupling member can include keyed connectors having a non-round shape to facilitate a 1:1 rotation ration of the catheter body and the stent member. In another embodiment, the coupling member can include a telescoping connector having an inner tube and a release wire disposed through the inner tube. A distal portion of the release wire has an outer diameter greater than an inner diameter of the inner tube such that the telescoping connector can be displace by the release wire. In another embodiment, the stent member includes a proximal retention member having arms that are outwardly extendable.

Abstract: A multi-lumen catheter can be used to measure pressure at multiple locations within the vasculature. The multi-lumen catheter can include multiple segments, such as a proximal portion, an intermediate portion, and a distal portion. A segment of a multi-lumen catheter may differ from another segment of the same multi-lumen catheter in radiodensity, hardness, and/or some other characteristic. Some multi-lumen catheters are designed to permit measurements of pressure in different lumens.

Abstract: The present disclosure relates to a drainage catheter and methods of use for providing improved catheterization procedures, such as during a percutaneous nephrostomy. The drainage catheter includes a body comprising a first tube segment and a second tube segment connected to one another at a curved end portion to form a continuous body structure. An inner surface of the curved end portion includes one or more drainage openings extending therethrough, with an outer surface of the curved end portion free of drainage openings to minimize potential clogging. The openings are in communication with a lumen that extends through the drainage catheter to provide a pathway for removing fluid from the kidney. The drainage catheter is inserted into the kidney via a first insertion site and exits via a second insertion site to minimize the potential for accidental removal of the catheter.
