Suturing devices and systems used to close openings into a biological structure. The suturing device can comprise an elongate member having a proximal end, a distal end, one or more arms, and one or more needles. One or more sheaths may be used with the device to maintain or substantially maintain haemostasis while the device is used and while a procedure is performed in the biological structure.

The present disclosure relates to medical devices comprising detachable balloons and catheter assemblies, wherein the detachable balloons are polymer balloons, metal balloons, polymer-coated metal balloons, and metalized polymer balloons. Various means of attachment and detachment of the balloons to the catheter assemblies are described. Kits and uses of systems having one or more medical devices, detachable balloons, and elongated or expandable bodies are also disclosed.

Vascular access devices and methods of their use are provided. In one embodiment, a vascular access device includes a catheter (112) and at least one deployable wire (134). The catheter includes a primary lumen extending from a proximal end to a distal end of the catheter. The at least one deployable wire is secured to the catheter and configured to move relative to the catheter between a delivery configuration and a deployed configuration.

An integrated sheath assembly for inserting a medical device such as a percutaneous pump into a vessel can include a first sheath having a first lumen defining a first opening between proximal and distal ends of the first sheath for passage of a portion of the pump and a second sheath having a second lumen defining a second opening between proximal and distal ends of the second sheath. The second lumen is expandable to allow passage of the first sheath containing the portion of the pump. The first sheath fills a space between the second sheath and the portion of the percutaneous pump when the first sheath containing the percutaneous pump is inserted into the second lumen. The first sheath has a first hub, and the second sheath has a second hub. In some embodiments, a single sheath and a movable connector can be integrated on the medical device.

An apparatus for performing phlebotomy through a peripheral intravenous line. The apparatus includes an introducer and a catheter configured to advance the catheter through a peripheral intravenous line. A y-adapter with a port of larger diameter is configured to receive the catheter and place in fluid communication with the peripheral intravenous line. When advanced the catheter is configured to transport a bodily fluid (i.e. blood) to a volume outside of the body.

Insertion devices, systems, and methods for inserting a needle into a target tissue in an individual in need thereof are disclosed herein. Also disclosed herein are needle cartridges comprising a needle, a plate, and a needle holder. Also disclosed herein are methods of introducing a catheter into a target tissue in an individual in need thereof.

A device for providing antegrade vascular access through retrograde approach is disclosed. The device includes a balloon arranged on a sheath and one or more side holes formed in the sheath proximal of the balloon. The balloon may be bulbous. A method for providing antegrade vascular access through retrograde approach is also disclosed.

A dilator assembly comprising an elongated body having a proximal end and a distal end, a first lumen extending along the body, a second lumen extending along the body so that it is a parallel to the first lumen, and a joint lumen disposed adjacent the distal end of the body, wherein both the first lumen and second lumen are in fluid communication with the joint lumen. A guidewire has a first end and a second end, and the first end of the guidewire is slidably received in the first lumen and the second end of the guidewire is slidably received in the second lumen.

Disclosed are coating compositions, processes, and designs for endowing vascular devices with thromboresistant and endothelializing properties. Also disclosed are designs of vascular devices used as aneurysm treating devices for assisting in the delivery, packing, and maintenance of embolization coils within an aneurysm, particularly a neurovascular aneurysm.

A surgical system according to one or more embodiments may include: a plurality of surgical instruments each including a flexible shaft and an end effector; an insertion tube to hold the plurality of flexible shafts and to be inserted into a body of a patient from one end of the insertion tube; and a support device for supporting the plurality of surgical instruments and the insertion tube. The support device includes a plurality of supports respectively supporting the plurality of surgical instruments, a support mechanism supporting the plurality of supports together, and an insertion tube holder holding the insertion tube. The plurality of supports independently and movably support the plurality of surgical instruments, respectively.
