A femoral arterial ECMO cannula is provided with a balloon that has dual flow and which provides arterial body blood flow during femoral ECMO (Extra Corporeal Membrane Oxygenation).

A medical device comprising a first tube, a second tube configured to sheath at least a portion of the first tube and configured to translate along a length of the first tube, an expandable device at a distal portion of the first tube, the expandable device having a collapsed state and an expanded state, a patch surrounding at least a portion of an outer surface of the expandable device, and a connector for holding the patch to the expandable device when the second tube covers the patch and the expandable device and for releasing the patch from the expandable device after the second tube uncovers the patch and the expandable device.

Disclosed is an apparatus and method for facilitating the implantation and secure positioning of implantable medical devices within a subcutaneous pocket formed by a surgeon within the patient. Such apparatus and method are configured to address the above-described challenges of containing implantable medical devices within such subcutaneous pockets, and the spring-like leads or catheters that may be attached to them, during implantation.

A barbed microcatheter includes a hollow tube having an elongated lumen, outwardly projecting barbs, fluid egress openings, a tissue anchor secured to a proximal end of the hollow tube, and a needle secured to the distal end of the hollow tube. The needle is used to form a first tissue opening at the first end of the wound. The hollow tube is pulled through the first tissue opening until the tissue anchor abuts against tissue at the first end of the wound. The needle is used to form a second tissue opening at the second end of the wound. The hollow tube is pulled through the second tissue opening so that barbs engage wound tissue. After cutting away the needle, a therapeutic fluid is introduced into the elongated lumen and passes through the fluid egress openings for infusing the wound with the therapeutic fluid.

Some embodiments of an anchor device may include bendable anchor mechanism that is deployable in a subcutaneous layer to releasably secure the anchor device to a patient's body. Certain embodiments of the anchor mechanism may include one or more barbs that flexibly bend in response to an insertion or removal force. As such, the anchor mechanism may be inserted into a subcutaneous layer, and removed from the subcutaneous layer, without the need for a separate actuation device to extend or retract the barbs.

A fixing device capable of being fixed, by simple fixing, to a living body without causing an occurrence of inflammation is provided. The fixing device 3 is fixed beneath the skin of the living body and includes a porous portion 31a capable of inducing cells thereto and a flat portion 31b that allows the cells to be adhered thereto, the porous portion 31a and the flat portion 31b are provided adjacent to each other, and a virtual surface SF1 of the porous portion 31a and a surface SF2 of the flat portion 31b are substantially flush with each other.

A kit includes a catheter and a catheter securing device. The catheter has a catheter shaft. The catheter securing device includes a base surface selectively securable to an intended surface and at least one catheter aperture. The catheter shaft extends through the at least one catheter aperture, such that the catheter securing device is mounted on the catheter shaft. The catheter securing device also includes a channel for stabilizing the catheter shaft thereon and a fastener repeatedly movable between a first position and a second position, independently of securement of the base surface to the intended surface. In the first position, the fastener permits substantially free sliding of the catheter shaft through the at least one catheter aperture, and, in the second position, the fastener substantially secures the catheter shaft to the catheter securing device in a substantially non-sliding manner.

Disclosed herein is a catheter, which in some embodiments includes a distal section configured to enter a skin insertion site. The distal section can include a tapered junction having one or more dilation structures configured to dilate the skin insertion site. The distal section can further include a distal portion extending from a distal end of the tapered junction, the distal portion having a diameter smaller than a proximal portion of the catheter. In combination, the tapered junction, the one or more dilation structures, and the specific actions of the user urging the catheter into the insertion site can result in an improved fit of the catheter in the insertion site.

Some embodiments of a medical device anchor system include an anchor device that receives a catheter (or other medical instrument) and secures the catheter in place relative to a skin penetration point. In some embodiments, the anchor device can secure the catheter in an operative position relative to the skin without the use of sutures or skin tapes. In particular embodiments, the anchor device can be adjusted to a folded condition so that subcutaneous anchors are partially rotated prior to removal from the skin penetration point.

A device for releasably and adjustably securing a medical tube includes a receiver and a tail, which may be used for thoracostomy. The receiver has a receiver aperture and receiver teeth. The tail has center holes along a central axis of the device. Raised tail teeth are formed on the tail between the central axis and the tail sides. The tail teeth are arranged to engage the receiver teeth when an end of the tail is fed through the receiver aperture to form a tail loop. The receiver teeth define receiver teeth apertures that are smaller than the receiver aperture. The tail loop is adjustable to tighten around the medical tube.
