A rectal medication administration device includes a tube, a balloon, a first valved port, and a second valved port. The tube includes a first lumen, a second lumen, and a plurality of holes extending from the first lumen therethrough. The balloon is proximal to the holes, is in communication with the second lumen, and is configured to be inflated to hold the tube in place within a patient's rectum. The first valved port is in communication with the first lumen and opens when connected to a first syringe or infusion set to provide medication transmission therethrough and closes when the first syringe or infusion set is withdrawn. The second valved port is in communication with the second lumen and opens when connected with a second syringe or infusion set to provide fluid to inflate the balloon and closes when the second syringe or infusion set is withdrawn.

The present disclosure generally relates to medical devices and methods for navigating a catheter shaft into the body of a subject during an intracoronary or other medical procedure and controlling the distal end of the catheter shaft. The present disclosure includes the use of an introducer positioning device that may be used in combination with an introducer. The introducer positioning device when used in combination with an introducer allows a catheter shaft to be inserted therethrough and into the introducer shaft located in the introducer where a distal end of the catheter shaft is aligned with the distal end of the introducer shaft.

A catheter assembly may include a catheter adapter having a catheter extending from its distal end. The catheter may include a proximal end, a tip, and a length of tubing therebetween. The length of tubing may include one or more position indicators to indicate a position of the catheter relative to a vasculature. The catheter assembly may include an introducer needle extending through the length of tubing and comprising a sharp distal tip configured to introduce the catheter into the vasculature.

A sheath assembly for the insertion of a percutaneous pump includes a tubular sheath body dimensioned for insertion into a blood vessel through a vessel aperture. The tubular sheath body includes a wall having a proximal end portion, a distal end portion, a longitudinal axis, an outer surface, an inner surface defining a first lumen substantially parallel to the longitudinal axis, and a second lumen disposed within the wall between the inner surface and the outer surface and extending from the proximal end portion to the distal end portion. The first lumen is dimensioned to allow passage of a portion of the percutaneous pump, and the second lumen is dimensioned for passage of a guidewire. A stylet is removably positioned to substantially occlude the second lumen. The stylet has a proximal end releasably secured to the sheath assembly.

The disclosure relates to a system of circumferentially (preferably helically) arranging indicia on the elongate body of a medical device such as a catheter. The disclosure also relates to an anchor drain for securing a surgical drain to a fluid collection device. The anchor drain resists disconnection of the surgical drain from the fluid collection device and also resists occlusion of the conduit connecting the surgical drain and the fluid collection device, even when a suture is tied about a portion of the anchor drain inserted within the surgical drain, and resists unintentional withdrawal of the surgical drain from the body or a body cavity.

An endovascular occlusion device. The endovascular occlusion device (300) has a balloon (306) and a catheter (304). The catheter (304) has a distal end (308), a proximal end, and a lumen (318) extending therebetween. The balloon (306) is positioned proximate to the distal end (308) of the catheter (304) and has a deflated state and an inflated state. The catheter (304) further includes a plurality of ports (314) proximate to a proximal end of the balloon (306). Each port (314) extends through a wall of the catheter (304) such that surface (316) of the catheter (304) is in fluid communication with the lumen (318) of the catheter (304). A flow restrictor (324) is positioned within, and is in sliding relation with, the lumen (318) of the catheter (304). Movement of the flow restrictor (324) is configured to close one or more ports (314) of the plurality so as to limit blood flow through the lumen (318) of the catheter (304).

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.

Devices and systems for navigation and positioning a central venous catheter within a patient. In an exemplary embodiment of a system of the present disclosure, the system comprises a first pole and a second pole, the first pole and the second pole configured to generate an electric field within a mammalian body sufficient to obtain a plurality of field measurements therein, and an elongated body configured for at least partial insertion into a blood vessel of the mammalian body and advancement through a vasculature, said advancement dependent upon the plurality of field measurements indicative of one or more locations of a portion of the elongated body within the vasculature. In at least one embodiment, the elongated body is configured as a stylet.

The invention generally relates to a continuous anesthesia nerve conduction apparatus and method thereof, and more particularly to a method and system for use in administering a continuous flow or intermittent bolus of anesthetic agent to facilitate a continuous or prolonged nerve block. In one embodiment, the apparatus includes a sheath having a proximal end, a distal end and at least one lumen extending from the proximal end to the distal end. The sheath also includes an embedded conductive element for transmitting an electrical signal from a proximal portion of the sheath to a distal portion of the sheath. A cannula is arranged in the at least one lumen of the sheath and has a distal end protruding from a distal portion of the sheath. The cannula is electrically coupled to at least a portion of the embedded conductive element and is configured to provide nerve stimulation.

A device for insertion of a flexible needle or other such instrument into a tissue, incorporating a collapsible support guide which supports that part of the needle which has not yet penetrated the tissue, preventing it from buckling, and an arrangement which pulls the needle from its proximal end to provide sufficient force for the penetration process. The collapsible support guide can be a pair of flexible strips connected along their length and enclosing the needle along its uninserted length in order to support it, with a mechanism at the distal end of the device to peel the strips from the needle as it is inserted. Insertion can be achieved by a pair of rollers engaging and advancing the strips distally. Alternatively, a telescopic support tube can be used to support the needle, the tube collapsing telescopically as the needle is inserted, to maintain clearance above the needle.
