Abstract: An example catheter includes an elongated member configured to be navigated through vasculature of a patient to a target treatment site in a vessel of the patient, a needle positioned at a distal portion of the elongated member, the needle configured to be within the elongated member when in a delivery configuration and radially extended to puncture a vessel wall of the vessel at the target treatment site when in a deployed configuration, and an expandable balloon including a needle guide configured to position a distal end of the needle at a predetermined distance from a central axis of the elongated member when the balloon is in an expanded configuration and the needle is in the deployed configuration.

Abstract: An advancer includes an advancer hub and an advancer shaft extending distally from the advancer hub. The advancer shaft includes a proximal end, a distal end, and a lumen extending from the proximal end to the distal end. The advancer shaft is configured to be disposed around an outer shaft of a delivery catheter, and includes a split line configured to enable splitting the shaft to enable removal of the shaft from the outer shaft. The advancer hub configured to be mounted on the outer shaft of the delivery catheter, and includes a parting line to enable splitting of the advancer hub.

Abstract: A device for creating an in-situ fenestration in a graft material of a stent graft at a fenestration site. The device includes an outer member forming a lumen and an inner member situated within the lumen of the outer member. The outer member includes one or more cutters configured to change from a delivery position to a cutting position via axial movement of the outer member and/or the inner member. The one or more cutters in the cutting position are configured to create the in-situ fenestration in the graft material of the stent graft at the fenestration site.

Abstract: A tissue-removing catheter for removing tissue in a body lumen includes a catheter body assembly having an axis and proximal and distal end portions spaced apart from one another along the axis. At least a portion of the catheter body assembly is sized and shaped to be received in the body lumen. A handle is mounted to the proximal end portion of the catheter body assembly and operable to cause rotation of the catheter body assembly. The handle includes internal handle components that interface with the catheter body assembly. The internal handle components provide at least four interface locations spaced axially along the catheter body assembly. A tissue-removing element is mounted on the distal end portion of the catheter body assembly. The tissue-removing element is configured to remove the tissue as the tissue-removing element is rotated by the catheter body assembly within the body lumen.
