Various embodiments are disclosed herein that generally relate to a three-dimensional (3D) hernia plug device and a method of manufacturing thereof. In at least one embodiment, there is disclosed a three-dimensional (3D) hernia plug, comprising: a waist portion extending, along a longitudinal extension axis, between a first waist end and a second waist end; one or more first overhangs coupled to the first waist end; and one or more second overhangs coupled to the second waist end, wherein the hernia plug is configured to translate between a pre-activation state and a post-activation state.

An axial support structure for a flexible elongate device may comprise a plurality of rigid links coupled by pin joints. Each of the plurality of rigid links may comprise a shaft, a pair of male joint connectors, and a pair of female joint connectors. Each male joint connector may comprise a male tab including an inner surface coplanar with an inner surface of the shaft and extending axially from a first end of the shaft. Each of the male joint connectors may include a pin extending radially. Each female joint connector may comprise a female tab having an outer surface coplanar with an outer surface of the shaft and extending axially from a second end of the shaft. The pair of female joint connectors may be rotated by 90 degrees relative to the pair of male joint connectors. Each female tab may define an aperture.

A lavage catheter for the treatment of a maxillary sinus is described. The catheter comprises a proximal portion and a distal portion. The distal portion comprises an irrigation tip. The irrigation tip has a tip opening through which fluid may be delivered by one handed operation of the catheter. A method for lavaging the maxillary sinus includes inserting the lavage catheter into a patient's anatomy and advancing the irrigation tip into the maxillary sinus using one hand.

A method of changing a catheter into a distal steering tool catheter includes adding to an existing catheter a tube assembly that passes through the catheter, the tube assembly including an internal tube and an external tube whose distal ends are coupled to each other and which are arranged for longitudinal axial movement relative to one another, and providing a tube manipulator coupled to the tube assembly, which is operative to cause relative axial movement of the internal and external tubes and bending of a distal portion of at least one of the internal and external tubes.

Systems, medical devices, and methods for steering the medical devices are disclosed. For example, a system can include an elongate medical device and a pump station. The medical device can include a tubular body with a lumen. The lumen, which terminates proximal of a distal end of the medical device, can be configured to contain a fluid. The pump station can be configured to pressurize the fluid and, thereby, induce a curve in at least a distal portion of the medical device for steering the medical device through one or more anatomical lumens. Being as the tubular body of the medical device (e.g., a stylet) is configured to be disposed in another lumen of another elongate medical device (e.g., a catheter), any curvature in the medical device can be imparted to the other medical device when disposed therein for steering the other medical device through the one-or-more anatomical lumens.

A percutaneous circulatory support device includes an impeller portion having a proximal end portion and an impeller being rotatable to cause blood to flow through the percutaneous circulatory support device. A catheter is coupled to the proximal end portion, and the catheter includes a preformed curve.

An intravascular device comprises an elongated outer catheter body having a proximal catheter end, a distal catheter end, and an inner catheter lumen extending between the proximal catheter end and the distal catheter end. The intravascular device further comprises an elongated inner articulating member slidably disposed within the inner catheter lumen. The inner articulating member has a proximal member end and an articulatable distal member end. The intravascular device further comprises a control assembly mechanically coupled to the proximal catheter end and the proximal member end. The control assembly is configured for distally translating the outer catheter body over the inner articulating member, and for articulating the distal member end.

A catheter for mapping and/or ablating a region of the heart includes an intermediate section that is connected to a tip assembly at a preset angle by a flexible preshaped section that is more flexible than the intermediate section. The flexible section may absorb displacement force applied to the tip assembly, such as when the tip assembly encounters uneven tissue surface, without displacing the intermediate section. The flexible section prevents excessive force from being applied to the tip assembly, reducing the risk of any of the following: a) mechanical perforation, b) steam pop, c) burying the tip assembly in the myocardium resulting in high temperatures, low energy delivery, thrombus formation and char formation.
