Aspiration catheter systems and methods of use
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.
INTEGRATED CATHETER ASSEMBLY
An integrated catheter assembly includes a housing member, an outer lumen member extending from the housing member, and a needle member slidably or movably coupled to the housing member, wherein the needle member can be extended beyond a first port of the outer lumen member in a first position and concealed in the outer lumen member in a second position. The outer lumen member has a side port between its first and second ports such that when the needle is extended in the first position and inserted into an arteriovenous fistula, blood from the arteriovenous fistula flashes into the needle member, is diverted through a relief port of the needle member out the side port of the outer lumen member for delivery to a dialysis machine. The assembly further includes an inner lumen member that is disposable through the housing member to extend out from the same the outer lumen member to provide dialyzed blood from the machine. The assembly therefore receives and delivers blood through a single injection site.
DEVICES, SYSTEMS AND METHODS USEABLE FOR TREATING SINUSITIS
Sinusitis and other disorders of the ear, nose and throat are diagnosed and/or treated using minimally invasive approaches with flexible or rigid instruments. Various methods and devices are used for remodeling or changing the shape, size or configuration of a sinus ostium or duct or other anatomical structure in the ear, nose or throat; implanting a device, cells or tissues; removing matter from the ear, nose or throat; delivering diagnostic or therapeutic substances or performing other diagnostic or therapeutic procedures. Introducing devices (e.g., guide catheters, tubes, guidewires, elongate probes, other elongate members) may be used to facilitate insertion of working devices (e.g. catheters e.g. balloon catheters, guidewires, tissue cutting or remodeling devices, devices for implanting elements like stents, electrosurgical devices, energy emitting devices, devices for delivering diagnostic or therapeutic agents, substance delivery implants, scopes etc.) into the paranasal sinuses or other structures in the ear, nose or throat. Specific devices (e.g., tubular guides, guidewires, balloon catheters, tubular sheaths) are provided as are methods for manufacturing and using such devices to treat disorders of the ear, nose or throat.
URINARY CATHETER WITH VARYING PROPERTIES
A urinary catheter and a method of its manufacture are disclosed. The urinary catheter comprises a tubular shaft extending between an insertion end and a discharge end, the tubular shaft being formed of at least two materials having different properties. The materials are arranged substantially separated from each other in distinct zones, wherein at least one of the width and thickness of said zones varies over the length of the tubular shaft, to form two or more uniform sections of the tubular shaft having various relative amounts of said materials, and wherein at least one transition between two such uniform sections is formed by at least one transition section providing a gradual transition between the uniform sections. The catheter can e.g. be produced by intermittent extrusion.
INTRAVASCULAR CATHETER DEVICE
The disclosure relates to a catheter device (1) comprising a catheter (2) and a hypodermic introducer needle (3), wherein an extended portion (19) of the hypodermic introducer needle (3) is provided with ribs (23, 23a) that circumvent said extended portion, and a proximal end (5) of the catheter (2) is provided with a locking flange (25) adapted to engage with the ribs (23, 23a), such that each rib engaging with the locking flange (25) will provide a tactile indication to the user of the advancement of the catheter (2) in relation to the needle (3).
VASCULAR ACCESS DILATOR APPARATUS AND METHOD OF USE
An improved vascular access dilator apparatus consisting of a wire, a blade with a locking safety mechanism, and straight but malleable dilator with a smooth surface having a lumen just large enough for the wire to slide easily in and out. The safety sheath covers the blade once an incision in the dermis is made, thereby protecting both the patient and caregiver.
DOME CATHETER SYSTEM FOR TRANSCUTANEOUS VACUUM ASSISTED CLOSURE OF PERIANAL OR ENTEROCUTANEOUS ABCESSES AND FISTULA TRACTS AND METHOD THEREOF
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 drainage devices
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.
PUNCTURE NEEDLE, CATHETER ASSEMBLY, AND VASCULAR PUNCTURE SYSTEM
A medical puncture needle includes: a metal needle body formed in a tubular shape, the needle body including: a blade surface located at a distal end portion of the needle body, a planar reflection portion located at an inner surface of the needle body and configured to reflect light, and a transmission window located proximal of the blade surface and configured to transmit reflected light reflected by the planar reflection portion.
PERITONEAL DIALYSIS CATHETER WITH AN EXPANDABLE STRUCTURE
Disclosed are peritoneal dialysis catheters comprising a distal region comprising a perforated portion and one or more expandable member configured to float the catheters on dialysate fluid within the peritoneal cavity of a patient, and methods for using the catheters.
