A valve for sealing the hub of a sheath assembly is provided. The valve includes a valve body having a solid thickness extending between a proximal surface and a distal surface. A bisecting slot extends across the proximal surface of the valve body and terminates at a depth less than the thickness of the valve body such that a portion of the valve body distally of the slot defines a bridge extending between opposed halves of the valve body such that the distal surface of the valve body is substantially continuous and a central portion of the proximal surface of the valve body is concave and defines a concave proximal portion.

Valve for dilator and sheath assembly

Disclosed is a multi-lumen catheter having a distal end catheter tip configured to improve fluid flow into and out from the catheter tip while reducing undesired recirculation during hemodialysis treatment of a patient. A first lumen and a second lumen each extends from the catheter proximal end to the catheter distal end, the first lumen and the second lumen being parallel to each other. A septum having a first side and a second side separates the first lumen from the second lumen. Some embodiments of the catheter tip include a beveled shape region, having a first lumen orifice, a second lumen orifice, and a septum top surface. Within the beveled shape region, at least a portion of the septum first side and at least a portion of the septum top surface form a first eave over the first lumen and at least a portion of the septum second side and at least a portion of the septum top surface form a second eave over the second lumen.

Catheter with tapered self-introducing low-recirculation distal tip

Various embodiments relate to catheter locking solutions and catheter locking therapies with use of trisodium citrate and ethyl alcohol, and in particular 4.0 to 15.0 weight/volume % trisodium citrate as an anticoagulant component and/or an antibacterial component and 15.0 to 25.0 volume/volume % ethyl alcohol as an antibacterial component. Use of the catheter locking solution and catheter locking therapy can reduce treatment failure during medical procedures that may employ catheters to supply treatment by at least significantly reducing the risks associated with bloodstream infections, catheter system malfunction, emboli formation, patient discomfort, and patient illness. These benefits can be partially due to the synergistic antibacterial effects of the trisodium citrate and ethyl alcohol in solution, generating an effective catheter locking solution with minimal concentrations of ethyl alcohol.

Catheter locking solution and catheter locking therapy

An intervertebral prosthetic implant having a first endplate having a first surface configured to substantially engage with a first vertebral body and a second surface having an extension with a concave contact surface, the concave contact surface being spaced apart from the second surface. A second endplate is provided with a first surface configured to substantially engage with a second vertebral body and a second surface comprising a convex contact surface, and the second endplate having a securing element positioned along and above the second surface defining a first and second window on opposing sides of the second surface. The securing element extends along the width and length of the lower endplate and configured with an access hole. An extension portion extends from the first surface of the first endplate through the access hole of the securing element and contacts the second surface of the second endplate.

Transforaminal prosthetic spinal disc apparatus

An artificial disc is disclosed. The artificial disc may include a superior endplate having a bi-convex superior surface and a concave inferior surface, and an inferior endplate having a bi-convex inferior surface. The artificial disc may also include a core assembly disposed between the superior endplate and the inferior endplate, and a support assembly disposed on outer surfaces of both the superior endplate and the inferior endplate. The support assembly may be configured to couple the superior endplate to the inferior endplate.

Artificial disc devices and related methods of use

A driving tool includes a shank, a sleeve, and a return spring disposed therebetween. The shank has a ball recess with a ball received therein. The shank has an interior interface adapted for receiving a tool bit. The ball recess substantially extends into the interior interface. The sleeve mounts on the shank to slide between limits. The sleeve has a first interior ball release recess followed by an interior ball lock surface and then a second interior ball release recess. The release recesses and surface are oriented with respect to the ball recess so as to permit selective displacement of the same over the ball recess to unlock the ball with movement in either direction. A return spring is disposed between the shank and the sleeve. The spring has a first and second end. One of the ends of the spring acts against a feature fixed with the shank and the other end of the spring acts against a feature fixed with the sleeve in a manner so as to permit selective displacement of the ball release recess and lock surface over the ball recess. The position of least spring potential energy is the position with the surface located just above the ball recess so as to tend to lock the ball into engagement with tool bit when the sleeve is in a rest position.
