A sheath for producing a fully sealed access to the interior of a vessel of an animal or human body comprises a base sheath having a tubular body defining a pass-through channel. The base sheath is adapted to be inserted into the vessel through a vessel aperture. The sheath further comprises an expansion device which is adapted to cooperate with the base sheath such that the outer diameter of the sheath increases in the region of the vessel aperture with the sheath in a stationary position in the vessel and upon actuation of the expansion device.

This present disclosure provides devices, systems, and methods relating to the management of a subject's medical needs involving safely accessing a body cavity. In particular, the present disclosure is directed to body cavity conduit devices and systems that facilitate repeated access to a subject's body cavity for removing fluid or performing a procedure in a manner that provides enhanced comfort, safety, and efficacy.

Endovascular drug delivery systems and methods are disclosed herein for delivering a therapeutic agent to the intracranial subarachnoid space of a patient, and/or deploying an endovascular drug delivery device distal portion in the intracranial subarachnoid space and a portion of the drug delivery device body in a dural venous sinus such that a therapeutic agent is delivered from the deployed drug delivery device into the intracranial subarachnoid space.

An inflatable port including a housing, a chamber in the housing, a septum over the chamber, a hollow stem extending from the housing, and a bladder around at least a portion of the housing. The chamber has a major opening and a minor opening. The septum is positioned over the major opening of the chamber and is fixed to the housing. The stem fluidly connects to the chamber by way of the minor opening of the chamber. The bladder is configured to increase a size of the inflatable port upon inflation of the bladder and decrease the size of the inflatable port upon deflation of the bladder. Also disclosed herein is a catheter assembly including the inflatable port, as well as a method related to the foregoing inflatable port and catheter assembly.

A barrier system is provided for use in reducing infections associated with post-operative surgical incision and/or a percutaneous medical device, such as a catheter, that is disposed within the surgical incision. Such a barrier system may include: a barrier device having a skin-contacting surface and a catheter-receiving surface; and an adhesive composition configured for adhering to skin, the barrier device, and/or the catheter so as to form a barrier at or adjacent to an incision in the skin where the catheter is percutaneously inserted through the skin. A tensioning anchor and associated system of two or more tensioning anchors is provided for post-operative wound closure. A method for applying and removing the barrier device and tensioning anchors is also provided.

Endovascular drug delivery systems and methods are disclosed herein for delivering a therapeutic agent to the intracranial subarachnoid space of a patient, and/or deploying an endovascular drug delivery device distal portion in the intracranial subarachnoid space and a portion of the drug delivery device body in a dural venous sinus such that a therapeutic agent is delivered from the deployed drug delivery device into the intracranial subarachnoid space.

An infusion pump includes a core member and a bladder member which are substantially spheroidal at one end and cylindrical at the other end. The core member is inserted inside the bladder member and a ring member engages the cylindrical ends of the core and bladder member to sealingly secure the bladder to the core. A tubular hose is included and is coupled with an infusion port of the core member. When fluid is injected into the pump, it causes the bladder member to inflate substantially symmetrically and spherically around an axial axis of the core member. Upon deflating the bladder member, the fluid is ejected out of the pump at a constant flow rate.

A barrier system is provided for use in reducing infections associated with post-operative surgical incision and/or a percutaneous medical device, such as a catheter, that is disposed within the surgical incision. Such a barrier system may include: a barrier device having a skin-contacting surface and a catheter-receiving surface; and an adhesive composition configured for adhering to skin, the barrier device, and/or the catheter so as to form a barrier at or adjacent to an incision in the skin where the catheter is percutaneously inserted through the skin. A tensioning anchor and associated system of two or more tensioning anchors is provided for post-operative wound closure. A method for applying and removing the barrier device and tensioning anchors is also provided.

Apparatus and methods are provided to position a device at adjacent tissues near a urethra to overcome the problem of urine leakage during physical movement or activity by changing a contour of a urethra. The devices may include mechanisms such as an inflatable pouch or a pillow anchored to the adjacent tissues of a urethra by an anchoring hook. The inflation of the pouch by an external fluid flexes the pouch towards a urethra and changes the contour of the urethra. The devices may also or alternatively include one or more tissue grasping T-fasteners having forward-facing and reverse-facing barbs to anchor the tissues adjacent to a urethra and bend the contour of the urethra. The device may also include actuators, clips or spring jacks having inflatable bands. The device may include a cap, one-way valves and a combination of a plug and cap to block urethral ostium to temporarily block urine flow from a bladder.

Endovascular drug delivery systems and methods are disclosed herein for delivering a therapeutic agent to the intracranial subarachnoid space of a patient, and/or deploying an endovascular drug delivery device distal portion in the intracranial subarachnoid space and a portion of the drug delivery device body in a dural venous sinus such that a therapeutic agent is delivered from the deployed drug delivery device into the intracranial subarachnoid space.
