A method of manufacturing a catheter shaft includes the steps of forming an inner layer of a first polymeric material, forming a plait matrix layer including a second polymeric material about the inner layer, and forming an outer layer of a third polymeric material about the plait matrix layer. The plait matrix layer includes a braided wire mesh partially or fully embedded within the second polymeric material, which is different from at least one of the first polymeric material forming the inner layer and the third polymeric material forming the outer layer. The second polymeric material has a higher yield strain and/or a lower hardness than at least the first polymeric material, and preferably both the first and the third polymeric materials. The first polymeric material and the third polymeric material may be different or the same. The catheter shaft may be formed by stepwise extrusion, co-extrusion, and/or reflow processes.

Implantable access port including a sandwiched radiopaque insert

An access port for subcutaneous implantation is disclosed. The access port may include a body for capturing a septum for repeatedly inserting a needle therethrough into a cavity defined within the body.

Mechanical assist device

Methods and apparatuses relate to an implantable device for providing contractile assistance to an organ. The device may include an actuator and anchors located on either side of the actuator. The anchors engage with oppositely positioned tissue walls of an organ chamber, and provide contractile assistance to the organ, repeatedly, at appropriate times. For example, the device may be implanted within the right ventricle, anchored to the right ventricular free wall and the ventricular septum. The device may function to bring the opposing walls of the ventricle toward one another, synchronized with the pacing of the heart, resulting in an improved ejection fraction of blood from the chamber. In some embodiments, the actuator includes a bladder that is configured to contract upon receiving an inflow of pressurized fluid therein. When the fluid exits therefrom, the bladder relaxes back to an initial, extended state.

CONNECTOR ASSEMBLIES

In one aspect, a connector assembly includes a delivery conduit defining a conduit lumen and a securable connector configured to secure the delivery conduit to a medical device hub defining a medical device hub lumen. The conduit lumen includes a constant diameter region along a portion of the delivery conduit and a transition region extending from the delivery conduit to the distal end. A transition region diameter of the transition region gradually increases from the constant diameter region to a distal end of the delivery conduit. The securable connector is coupled to an outer surface of the delivery conduit and is slidable along a portion thereof. The securable connector is configured to receive the medical device hub. The securable connector is secured relative to the delivery conduit so as to fluidically couple the conduit lumen with the medical device hub lumen.
