Abstract: Medical devices for delivering a plug to a void within a patient. The medical device can include a fluid delivery device and a plug holder (e.g., a plug delivery device) coupled to a distal end of the fluid delivery device. The medical device may be configured such that the delivery of fluid from the fluid delivery device wets the plug, ejects the plug from the plug holder, and pushes the plug through a lumen of an elongate tube to a void within a patient.

The thread can exhibit various shapes and dimensions selected to enhance particular aspects of performance when the stent placed in an anatomical structure of a patient.

Abstract: A convertible nephroureteral catheter is used in the treatment of urinary system complications, particularly on the need for a single surgically delivered device to treat patients who must be seen by an interventional radiologist (IR). In many current procedures, patients need to return to the operating room to remove a previously delivered nephroureteral catheter to exchange this catheter with a fully implanted ureteral stent delivered though the same access site at the flank. The present convertible nephroureteral catheter reduces the need to return for a second surgical procedure. Two weeks after initial implantation, the proximal portion of the convertible nephroureteral catheter extending out from the body may simply be removed. A simple action at the catheter hub allows this proximal portion to be removed, leaving behind the implanted ureteral stent within the patient's urinary system. Other medical procedures, devices, and technologies may benefit from the described convertible catheter.

Abstract: Medical devices including vascular access kits and related methods are disclosed. In some embodiments, a vascular access system may include a first conduit, a second conduit, and a connector that is reversibly or irreversibly coupled to both the first and second conduits such that there is a continuous lumen from the first conduit and the second conduit. In some embodiments the vascular access system may include a connector where the inside geometry of the connector enhances laminar flow. The vascular access system, when implanted and assembled, may be a fully subcutaneous surgical implant.

Abstract: The invention relates to a device in the form of a perforating trocar and is intended in particular to be used for surgery and interventional radiology. The device comprises an outer sleeve (5) having a rigid tube (8), and a mandrel (6) having a rod (18). The rod (18) is suitable for sliding in the outer sleeve (5) and has, at its distal end, a perforating tip (21, 33). The rod (18) additionally has a longitudinal groove (20) arranged on the surface of the rod (18), and extending from the distal end to the proximal end of the rod (18), in order to allow the device to slide on a guide pin.

Abstract: A catheter system for accessing the central venous system through an occlusion in the neck region.

Abstract: Some of the present methods include, and some embodiments of the present systems are configured for gaining access to a patient's vessel by way of the vessel (i.e. from the inside out). Some embodiments facilitate gaining access to an occluded vessel, where part of the access path is through the occlusion.

Abstract: A biopsy needle device is disclosed. The biopsy needle device may be configured to be advanced to a predetermined tissue sample, sever the tissue sample, and extract the tissue sample from a body tissue of a patient. The biopsy needle device may be further configured to dislodge the tissue sample from the biopsy needle device utilizing a stylet.

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: Medical devices for delivering compositions or medical articles to a patient are disclosed. The medical plug delivery devices can include a fluid delivery device (e.g., a syringe), a frame, and a rotatable magazine. The rotatable magazine can include a plurality of chambers that each hold a composition or a medical article (e.g., a medical plug). By rotating the rotatable magazine relative to the frame, material within the chambers of the rotatable magazine can be sequentially deployed to a patient.

Abstract: Medical devices including a cap for a medical connector are disclosed. In some embodiments, the cap comprises a disinfectant, such as an antiseptic fluid and an insert configured to seal or partially seal the medical connector as it is engaged with the cap. In some embodiments the cap insert has a segment which is deformable under axially applied pressure as an end-user attaches the cap to the medical connector. In some embodiments this insert is configured to improve the exposure of antiseptic to the outer surface of the medical connector while minimizing exposure of the antiseptic inside the medical connector open lumen.

Abstract: Hemostasis valves and hemostasis valve systems are provided. A hemostasis valve can include a valve member, wherein the valve member includes a first sealable opening disposed through a first portion of the valve member and a second sealable opening disposed through a second portion of the valve member. The valve member may also include three or more sealable openings. A hemostasis valve system may include a hemostasis valve and another medical device. The hemostasis valve may be releasably coupleable to the other medical device.

Abstract: Devices and methods used to drain a spinal cyst are disclosed. An opening may be created by a medical device, such as a nested needle assembly, that is inserted percutaneously into a facet joint adjacent to the cyst. The needle assembly may include a first elongate member, needle or introducer cannula; a second elongate member, inner cannula, needle, or trocar; and a piercing needle. The piercing needle may be used to microfenestrate a wall of the cyst such that fluid within the cyst is permitted to drain from the cyst.

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.
