12171970 · 2024-12-24 · ·

A vascular access device including a catheter adapter, a port opening, and an elastomeric valve. The catheter adapter extends along a longitudinal axis and includes a proximal end, a distal end, and a lumen extending therebetween. The port opening is formed in a surface of the catheter adapter in fluid communication with a side port of the catheter adapter and the lumen. A structural geometry of the port opening directs a fluid into the lumen in a proximal direction. The elastomeric port valve is disposed within the lumen and configured to deform in response to a transverse force applied thereto. A proximal gap may result between the inner wall forming the lumen and a proximal side of the elastomeric port valve, thereby opening a fluid path.

A T-site connector has a T-site body, which includes a primary luer body and a tube bond stem, a septum, and an externally threaded cap. The T-site body includes a septum housing at a proximal end of the T-site body. The T-site body also includes the tube bond stem extending outwardly from the primary luer body. The internally threaded collar is secured such that the internally threaded collar is free-spinning to rotatably secure to a catheter. The septum has a slit for receipt of a cannula therethrough. The externally threaded cap is configured to secure to the septum housing of the T-site body with the septum therein. The externally threaded cap is configured to receive a proximal connection device thereon.

Feeding tube aperture

System and method for blood filtering and/or treatment
09649427 · 2017-05-16 · ·

A system for filtering or treating blood of a subject is provided herein. The system includes a bone port for establishing fluid communication with a bone marrow of the bone and a return port for returning blood from the bone marrow to a circulation of the subject. The system further includes a blood treatment or filtering device interposed between the bone and return ports thereby establishing a mini-circulatory system.

Venous Access Implantable Port
20170128709 · 2017-05-11 ·

A venous access implantable port allows a doctor or medical practitioner to use the same injection or extraction site for multiple procedures. The venous access implantable port includes a port body, a venous access orifice, a fluid reservoir, at least one fluid transport tube, and a catheter. The port body is transdermally positioned at the procedural location. The venous access orifice traverses into the port body in order to allow a needle to be inserted through the venous access orifice to extract or inject fluid into the fluid reservoir integrated into the port body. The fluid reservoir is in fluid communication with a patient's circulatory system through the catheter and the at least one fluid transport tube traversing into the port body, in order to allow the extraction or injection of fluids into the circulatory system.

Surgical access assembly and method of using same
09622777 · 2017-04-18 · ·

A surgical access assembly and method of use is disclosed. The surgical access assembly comprises an outer sheath and an obturator. The outer sheath and obturator are configured to be delivered to an area of interest within the brain. Either the outer sheath or the obturator may be configured to operate with a navigational system to track the location of either within the brain. Once positioned at a desired location, the obturator is removed, leaving a distal end of the outer sheath adjacent an area of interest, and creating a working corridor. Interventional devices may be introduced to the area of interest, as well as a variety of treatments. A subsequent treatment process may also be employed.

Low-profile surgical access devices with anchoring

A surgical access device includes a proximal housing having proximal and distal end portions, the distal end portion of the housing being configured and adapted to engage a proximal portion of a flexible wound retractor. The proximal housing can be provided with a plenum chamber being defined therein, the plenum chamber being in fluid communication with at least one nozzle. The nozzle is preferably configured to direct pressurized fluid in an axial direction from the plenum chamber into a central bore of the surgical access device to provide a constant gaseous seal around a surgical instrument inserted therethrough, while inhibiting a loss of pressurized fluid from the body cavity therethrough. The plenum chamber can be adapted and configured to receive pressurized fluid and conduct the pressurized fluid to the at least one nozzle.
