The present invention relates to a sheath system that enables endovascular imaging and treatment of concomitant multiple lesions, both in antegrade and retrograde direction in a blood vessel. Further, the present invention relates to a method for using the sheath system enabling endovascular imaging and treatment of concomitant multiple lesions, both in antegrade and retrograde direction.

A balloon catheter having an elongated catheter shaft defining a fluid drainage lumen and a balloon inflation lumen. The balloon catheter includes a fluid drainage port disposed about the distal end of the catheter shaft in fluid communication with the fluid drainage lumen, and a balloon inflation port disposed about the distal end of the catheter shaft in fluid communication with the balloon inflation lumen. A balloon portion is disposed about the distal end of the catheter shaft in fluid communication with the balloon inflation port. A release device is disposed in fluid communication with the balloon portion and the fluid drainage lumen, and includes an activating member. A tether is attached to the activating member of the release device. Tension applied to the tether activates the release device, enabling fluid flow from the balloon portion into the fluid drainage lumen and out of the body.

A device comprises a tubular member with a longitudinal axis having a proximal end and a distal end, at least one partial cut located at, along or near the distal end of the tubular member, the at least one partial cut comprising an orientation that is angled relative to both the longitudinal axis and an axis transverse to the longitudinal axis, a pusher member positioned within an interior of the tubular member and configured to selectively advance the distal end of the tubular member longitudinally, wherein the distal end of the tubular member is configured to at least partially rotate when the pusher member is advanced relative to the tubular member so at to facilitate placement of the distal end in a particular branch of a subject's intraluminal network, wherein the distal end of the tubular member is configured to longitudinally elongate along or near an area of the at least one partial cut.

A catheter pump system is disclosed. The catheter pump system can include a shaft assembly and an impeller coupled with a distal portion of the shaft assembly. A motor assembly can impart rotation on the impeller through the shaft assembly, the motor assembly comprising a motor which rotates the shaft assembly. The catheter pump system can include a fluid pathway which conveys fluid proximally during operation of the catheter pump system. A seal can be disposed between the motor assembly and the impeller. The seal can be configured to impede or prevent the fluid from the fluid pathway from entering the motor assembly at least about an outer periphery of the shaft assembly. The seal can comprise an opening through which a portion of the shaft assembly extends.

Disclosed herein is a catheter advancement device having an elongate shaft and a capsule attached to or integral with the shaft, and related methods for assisting with advancement of catheters such as cardiovascular guiding catheters while reducing damage to the inner wall of the blood vessel. Some capsules have a distal plug portion and a neck portion having a smaller diameter than the plug. Other capsules have a channel defined along the outer surface of the capsule. Some elongate shafts have an attachment tube disposed at or near the proximal end thereof.

An indwelling valve actuated urinary catheter has an inner catheter having an inlet port configured on a distal end and for locating within the bladder and a sheath that extends over the inner catheter to produce a valve. The sheath extends over the inlet port when the valve is in a closed position and manipulation of a valve actuator on the proximal end, located within the penis, opens the valve. A bladder plug configured on the distal end of the inner catheter may form a seal between the catheter sheath and the inner catheter. The valve actuator may comprise a proximal nodule and a distal nodule that are configured within the urethra along the penis. Manual manipulation of the valve actuator through the penis, such as by pinching the penis, moves the proximal and distal nodules with respect to each other to open or close the valve.

A smart obturator assembly includes a hub forming a central passage. The hub is configured to couple to a proximal end of a device that forms a lumen such that the central passage is in fluid communication with the lumen. A collar on the hub includes electronic circuitry in signal communication with remote reception circuitry. An obturator is movably positionable within the lumen. The obturator is movable within the lumen between a first position and a second position. The obturator includes a distal end and a sensor at the distal end. The sensor is configured to sense an environmental characteristic within a patient’s blood stream, generate a signal representative of the environmental characteristic, and transmit the signal to the electronic circuitry. The electronic circuitry is configured to receive the signal and transmit the signal to the remote reception circuitry.

A temporary low profile intraluminal catheter for infusing agents into, or extracting fluids from, a bodily lumen featuring securement structure, wherein the securement structure allows the catheter to be placed with minimal intrusion into the bodily lumen is disclosed. With such design affording a more efficient, verifiable placement of the catheter with less complication due to infection and biofilm related issues, among other types of complications.

Devices and methods for providing an internal balloon sheath are disclosed. One device includes a sheath for insertion through an arteriotomy of a patient. The sheath comprises a tubular sheath body having a longitudinal axis, an open proximal end, an open distal end, an outer surface and an inner surface, the inner surface defining a lumen between the proximal and distal ends for passage of a catheter device. The sheath also comprises an inflatable balloon disposed within the lumen. The inflatable balloon is configured to occupy a longitudinal space in the lumen between the inner surface of the sheath body and the catheter device when the catheter device is disposed within the sheath and the balloon is inflated, and fluidically seal the lumen.
