A catheter assembly may include a catheter adapter, which may include a body and a side port extending outwardly from the body. The body may include a distal end, a proximal end, and an inner surface extending through the distal end and the proximal end and forming a lumen. The catheter assembly may include one or more components to facilitate flushing of the catheter assembly. For example, an angle of the side port with respect to a longitudinal axis of the body may be adjustable. The catheter assembly may include a catheter extending distally from the distal end of the catheter adapter. The catheter assembly may include a septum disposed within the lumen proximal to a side port pathway extending through the side port and in fluid communication with the lumen.

A hemostasis valve assembly for use in a medical device. The hemostasis valve assembly may include a main body portion defining an internal cavity, a seal cartridge disposed within the internal cavity, and a low pressure valve assembly positioned within the internal cavity adjacent to the seal cartridge. The low pressure valve assembly may include a first valve member having a first valve body and a second valve member having second valve body. A portion of a distal side of the first valve member may abut at least a portion of a proximal side of the second valve member.

A catheter assembly may include a catheter adapter, which may include a distal end, a proximal end, a lumen extending between the distal end and the proximal end, and a side port. A septum may be disposed within the lumen of the catheter assembly. The side port may include a lumen in fluid communication with the lumen of the catheter adapter. The lumen of the side port may be distally-facing, which may facilitate flushing of fluid trapped proximate a distal face of the septum. The catheter assembly may include a catheter secured within the catheter adapter and extending distally from the catheter adapter.

Devices and methods for management of a guidewire during catheter insertion. Particular embodiments include unidirectional valves to allow movement of a guidewire in one direction only.

Rapidly insertable central catheters (“RICCs”), RICC insertion assemblies, and methods are disclosed. For example, a RICC insertion assembly can include a RICC, an introducer, and an access guidewire. An introducer needle can include a needle shaft having a longitudinal gap extending from a proximal portion of the needle shaft through a needle tip. An introducer sheath can include a splittable sheath hub coupled to a splittable sheath body. The introducer sheath can be disposed over the introducer needle with the sheath body sealing the needle shaft for drawing a vacuum through the introducer needle. The access guidewire can extend along an entirety of a primary lumen of the RICC, through a splittable valved port of the sheath hub, along a sheath body-covered needle channel of the needle shaft, and to a location in the introducer proximal of the needle tip in a ready-to-operate state of the RICC insertion assembly.

Mechanical thrombectomy apparatuses including an inverting, rolling conveyor region (“tractor”) at the distal end that are configured to grab and remove thrombus material. In particular, described herein are mechanical thrombectomy apparatuses that are adapted to prevent premature deployment of the tractor, e.g., by including a tractor hold (e.g., a housing, a lock, a clamp, etc.) or the like to secure the outer end of the tractor against and/or relative to the elongate inversion support.

In one embodiment, a fluid storage device includes a rigid outer housing that defines a septum cavity, a reservoir cavity, and a channel that extends between the two cavities, the outer housing further defining an outlet in fluid communication with the reservoir cavity, a septum provided within the septum cavity, the septum being made of an elastic polymer and facilitating refilling of the fluid storage device, and a thin, collapsible membrane that does not generate significant restoring forces when it is deformed as fluid is drawn from the reservoir cavity and, therefore, does not completely or partially return to its initial non-deformed shape even if the outlet of the device remains open after doses are administered.
