An all-purpose drainage catheter which includes an all-purpose drainage catheter lumen, an extension tubing, a collection bag, a catheter hub, a Luer valve. The extension tubing inserted into the all-purpose drainage catheter lumen. The collection bag is fluidly coupled to the extension tubing. The Luer valve facilitates nephrostomy care so that when the all-purpose drainage catheter is in place urine flows from the renal pelvis into the all-purpose drainage catheter lumen, the extension tubing and the collection bag. The Luer valve employs a scalloped Luer-style male connector which, when screwed into the catheter hub, further allows urine to flow from the renal pelvis into the all-purpose drainage catheter lumen, the extension tubing and the collection bag. The all-purpose drainage catheter includes an outer catheter hub, an inner catheter hub coupled to the Luer valve at one end thereof and insertedly coupled to the outer catheter hub. A gear rack has a set of ratchet teeth and is disposed on and coupled to the inner catheter hub. A ratchet pawl disposed on and coupled to the outer catheter hub and aligned with the gear rack so that the ratchet pawl engages one of the ratchet teeth to secure the inner catheter hup to the outer catheter hub.

A lumen extension member is provided for a catheter having a catheter body and an elongate electrode coupled to the catheter body. The elongate electrode defines an electrode lumen extending therethrough. The lumen extension member is positioned within the electrode lumen and is coupled to the catheter body. The lumen extension member includes a tubular member including a sidewall and at least one opening that extends through the sidewall.

An elongated catheter assembly defines a catheter lumen configured to receive the distal guidewire section of the guidewire, and also defines an axial portal and a radial portal. A guidewire deflector is mounted to the elongated catheter assembly. The guidewire deflector is configured to selectively deflect urged axial movement of the distal guidewire section of the guidewire away from the axial portal and radially toward the radial portal.

The disclosure sets forth various exemplary embodiments of systems, methods, and/or medical apparatuses including but not limited to: a sheath; and a balloon disposed at a working distal end of the sheath. According to one example embodiment the medical device can include where the sheath can include woven wire reinforcing axial and longitudinal strength, side holes, a one direction distal valve, and can include an inflator. According to one example embodiment the medical device can include where the sheath can include a narrow cross-section of, e.g., 7-8 Fr and balloon of length of, e.g., 12 cm.

A catheter for transcutaneous and transluminal vacuum closure of perianal or entero-cutaneous fistulas and abscesses containing a body ending in a dome having a low-friction surface and equipped with a series of openings on the surface that connect inside the catheter body into a catheter chamber, which is then connected to a tube connected to a vacuum generating system characterized in that the catheter body on the outside has edges arranged in the shape of many helicoid coils, and in the grooves between these coils the series of openings are made into the chamber inside the catheter.

Steerable, elongated medical devices that are inserted into a patient's body are disclosed. The devices include first and second wires slidably extending longitudinally through a wall of a tube and attached adjacent a distal end of the tube. The devices also include a tension control member configured to selectively apply a tension force to the wires to bend the tube.

A medical device includes: a tube through which fluid flows; a handle part coupled to a proximal end part of the tube; an electrode tip coupled to a distal end part of the tube; a fluid injection part configured to inject fluid into the tube; one or more openings formed in the tube; and a guide member disposed in the tube, and having an inclined part to guide the direction of the fluid sprayed out through the opening.

A method and device for modulating the autonomic nervous system adjacent a pericardial space to treat cardiac arrhythmia includes a treatment source arranged to supply a treatment medium, a catheter having an end sized for insertion into the pericardial space, a medium delivery assembly having a distal end arranged to be positioned by the catheter into the pericardium, with the distal end of the delivery assembly comprising a delivery tip arranged to extend away from the distal end of the catheter into the pericardial space. A connector operatively couples the delivery tip of the medium delivery assembly to the treatment source, and the delivery tip of the medium delivery assembly including a plurality of delivery points for delivering the treatment medium at a plurality of treatment areas within the pericardial space. The device performs modulation or ablation of the autonomic nervous system at selected treatment areas within the pericardium.

A catheter comprising an elongated body (12) defining one or more lumens (40,42), and the elongated body comprises a sidewall defining a side opening (14) in fluid communication with a lumen of the one or more lumens. The side opening has a proximal end (14A), a distal end (14B), a first side (34) extending from the proximal end to the distal end, and a second side (36) opposing the first side and extending from the proximal end to the distal end. When the elongated body is straight, the first and second sides curve towards each other between the proximal and distal ends, e.g., to define a biconcave shape.

A cannula apparatus (100) and method are provided for selective fluid flow in removal and return directions. An outer sheath (102) has proximal (104) and distal (106) outer sheath ends spaced apart by a longitudinal outer sheath body (108) defining an outer sheath lumen (110). At least one fluid removal aperture (112) extends through the outer sheath body. The outer sheath includes a side access aperture (114). An introducer (1534) has proximal (1536) and distal (1538) introducer ends spaced apart by a longitudinal introducer body (1540), which at least partially defines a guidewire channel (1542) longitudinally therealong. The introducer is configured for insertion into the outer sheath lumen with the guidewire channel in fluid communication with the side access aperture. An inner tube (218) has proximal (220) and distal (222) inner tube ends. At least one fluid return aperture (228) is located at least one of at and adjacent the distal inner tube end to place an inner tube lumen in fluid communication with an ambient space.
