An integrated catheter assembly includes a housing member, an outer lumen member extending from the housing member, and a needle member having a needle slidably or movably coupled to the housing member, wherein the needle can be extended beyond the outer lumen. Once a flash of blood is confirmed the needle member is uncoupled from the housing member and removed from within the patent's vein or artery. An inner lumen member having an elongated member housing an inner lumen is then connected to the housing member. A thump slide supported within the elongated member and coupled to the inner lumen is advanced moving the inner lumen through the housing member and the outer lumen into the patient's vein or artery beyond the end of the outer lumen The end of the thump slide/elongated member is connected to tubing extending to a dialysis machine and this tubing is used to transfer clean or detoxed blood from the machine back into the patent. The outer lumen is connected to separate tubing to transfer blood out of the patent to the dialysis machine. The integrated catheter assembly therefore receives and delivers blood through a single injection site. Alternatively, another embodiment is shown where the needle remains within the patient during dialysis.

An assembly includes a catheter that has an insemination lumen for injecting sperm into a uterus. The insemination lumen includes two branches (sub-lumens), one directed toward a left ostium and the other directed to a right ostium of fallopian tubes.

Disclosed is a multi-lumen catheter having a distal end catheter tip configured to improve fluid flow into and out from the catheter tip while reducing undesired recirculation during hemodialysis treatment of a patient. A first lumen and a second lumen each extends from the catheter proximal end to the catheter distal end, the first lumen and the second lumen being parallel to each other. A septum having a first side and a second side separates the first lumen from the second lumen. Some embodiments of the catheter tip include a beveled shape region, having a first lumen orifice, a second lumen orifice, and a septum top surface. Within the beveled shape region, at least a portion of the septum first side and at least a portion of the septum top surface form a first eave over the first lumen and at least a portion of the septum second side and at least a portion of the septum top surface form a second eave over the second lumen.

A medical device, which may be adapted for delivering and/or recapturing an implantable implant, includes an elongate sheath and a rigid member that is secured relative to the elongate sheath. The elongate sheath includes an inner polymeric liner, an outer polymeric sheath and a reinforcing braid that extends within the outer polymeric sheath. The reinforcing braid includes a plurality of wire ends that extend beyond a distal edge of the rigid member in order to protect the implantable implant from being damaged by the rigid member in the event that the inner polymeric liner becomes damaged.

A ureteral catheter includes a drainage lumen having a proximal portion configured to be positioned in at least a portion of a patient's urethra and/or bladder and a distal portion configured to be positioned in a patient's kidney, renal pelvis, and/or in the ureter adjacent to the renal pelvis. The distal portion includes a retention portion for maintaining positioning of the distal portion of the drainage lumen. The retention portion includes a plurality of sections, each section having one or more openings on a sidewall of the retention portion for permitting fluid flow into the drainage lumen. A total area of openings of a first section of the plurality of sections is less than a total area of openings of an adjacent second section of the plurality of sections. The second section is closer to a distal end of the drainage lumen than the first section.

An apparatus is provided that is operable in different modes to perform various functions for treating a body lumen. The apparatus includes a shaft including proximal and distal ends, a lumen extending there between, and a balloon on the distal end. The apparatus includes a valve on the distal end that selectively opens or closes an outlet communicating with the lumen. With the valve open, fluid introduced into the lumen exits the outlet into a body lumen. With the valve closed, fluid introduced into the lumen expands the balloon. The valve may be biased to be closed, e.g., by a spring element disposed within the balloon. Optionally, the apparatus also includes an actuator for expanding a helical member within the balloon interior, e.g., either before or after expanding the balloon, such that the helical member and balloon may adopt an expanded helical shape for removing material within a body lumen.

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

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

A method and devices for mitigating the risk of limb ischemia includes inserting a femoral arterial cannula into a femoral artery of a limb, the femoral arterial cannula having a low-profile balloon to seal the femoral artery. Once in situ in the femoral artery, the femoral arterial cannula balloon is inflated to seal said femoral artery to deliver blood flow in a retrograde direction to said limb while simultaneously delivering systemic arterial blood flow. A femoral venous cannula is also inserted into a femoral vein of said limb, the femoral venous cannula having a broad-profile balloon to seal the femoral vein. Once in situ in said femoral vein, the femoral venous cannula balloon is inflated to seal the femoral vein to drain venous blood flow from the limb while simultaneously draining systemic venous blood flow.

A needle assembly, such as a catheter assembly, having a needle shaft with a needle tip formed from a first rigid material for puncturing a subject. The shaft section, proximal of the needle tip can be formed from a second material different from the first material. The needle tip is attached to the needle shaft to form the needle. The first material can have higher rigidity than the second material and the needle can project through a catheter tube and used in a catheter assembly.
