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 penetration point without use of sutures or skin tapes.

An attachment device for securing a medical device to a patient, comprising at least one layer including a flexible portion and a rigid portion. The rigid portion being connected to the flexible portion and defining at least one loop. The at least one loop including an elongate body and an anchoring element. The elongate body having a first end and a second end opposite the first end. The anchoring element being disposed circumferentially around, and connected to, the elongate body.

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.

Central catheters, central catheter assemblies, and methods thereof. A central catheter includes a catheter tube coupled with a number of the extension legs, a needle hub coupled with the catheter tube, where the needle hub is configured to receive a needle therethrough so that the needle is disposed within a primary catheter tube lumen. The central catheter includes a manifold hub for coupling the extension legs with the catheter tube. The manifold hub may be integral to the needle hub. The needle hub includes a septum within a needle hub lumen, where the septum is configured to define a fluid tight seal with a needle and to prevent fluid flow through the proximal portion of the needle-hub lumen when the needle is withdrawn from the needle-hub lumen. A method for introducing a central catheter into a blood vessel.

An apparatus includes a body, a needle, a catheter, and an actuator assembly. The needle extends distally from the body. The needle has an inner wall defining a needle lumen. The needle lumen is in fluid communication with a fluid port of the body. The catheter is slidably disposed in the needle lumen. The catheter has a catheter lumen. The first actuator assembly is configured to translate the catheter within and relative to the needle. The apparatus may also include an actuator assembly that is configured to rotate the needle relative to the body. The apparatus may be used to first deliver a leading bleb of fluid to the subretinal space in a patient's eye via the needle. The apparatus may then be used to deliver a therapeutic agent to the subretinal space in the patient's eye via the catheter.

The present disclosure describes devices, systems, and methods for intravascularly delivering an implantable device to a targeted anatomical site such as the mitral annulus. A delivery system includes a delivery member coupled to a handle assembly and extending distally from the handle assembly. A delivery catheter is concentrically positioned within an outer member and configured to advance the intravascular device relative to the outer member. The delivery catheter includes a distal can structure configured to house at least a portion of the intravascular device in a compressed, pre-deployed position.

An external fixation system for percutaneous drainage procedures may include a base with a first and second side, a first coupler couplable to a conduit, and a second coupler couplable to a drainage bag or mechanism to flush or evacuate a drainage tube during use. The system may be modified to include a locking mechanism to secure conduit sutures. The system may also be used to convert a standard drainage tube into a low profile drainage tube. Also disclosed herein are methods and devices for converting standard feeding tubes into low profile feeding tubes.

A medical device securement system includes a main body having a first section and a second section displaceable relative to one another to translate the system between an undeployed state and a deployed state, a first array of microneedles projecting from a tissue contacting surface of the first section and a second array of microneedles projecting from a tissue contacting surface of the second section, a retention device provided on the main body for receiving and engaging the medical device, wherein the first section comprises a first base defining the tissue contacting surface and a closure member hingedly articulated relative to the first base between a closed position defining an enclosure between the first base and the closure member in which the retention device is located and in which the medical device may be at least partially contained, and an open position permitting access to the enclosure.

The present invention is directed to systems, devices and methods for trans-septally delivering carbon dioxide through a minimally invasive catheter to create a gaseous pocket or emphysema between the posterior wall of the left atrium and the esophagus during cardiac ablation of the left atrium. This pocket of gas expanded tissue serves to thermally insulate and separate the esophagus from the left atrium during ablation to prevent the formation of an atrial-esophageal fistula. The system comprises a control system to precisely deliver the gas to a desired location through a needle-based catheter assembly.

A sheath assembly for the insertion of a percutaneous pump includes a tubular sheath body dimensioned for insertion into a blood vessel through a vessel aperture. The tubular sheath body includes a wall having a proximal end portion, a distal end portion, a longitudinal axis, an outer surface, an inner surface defining a first lumen substantially parallel to the longitudinal axis, and a second lumen disposed within the wall between the inner surface and the outer surface and extending from the proximal end portion to the distal end portion. The first lumen is dimensioned to allow passage of a portion of the percutaneous pump, and the second lumen is dimensioned for passage of a guidewire. A stylet is removably positioned to substantially occlude the second lumen. The stylet has a proximal end releasably secured to the sheath assembly.
