Neurosurgical apparatus has a guidance device having a guide tube and a neurosurgical instrument for insertion into the guide tube. The inner surface of the guide tube is arranged, for example profiled, to at least partially engage the outer surface of the neurosurgical instrument when inserted therein. The guide tube thus guides the neurosurgical instrument along a predefined path through the guide tube. At least one of the guidance device and the outer surface of the neurosurgical instrument are configured to provide a fluid return path for carrying any fluid displaced from within the guide tube during insertion of the neurosurgical instrument into the guide tube. A seal may also be provided for sealing the fluid return path.

A device for reducing agent penetration at an insertion site is provided that has a porous inner sleeve fluidly connected to a conduit. A vacuum or hydrodynamic source is fluidly connected to the conduit. The device is stabilized by fibroblast in-growth and inhibits bacterial colonization. A device is also provided that has a conduit having a bore and an outer conduit surface. The outer conduit surface is optionally nanotextured to promote fibroblast adhesion and limit bacterial residency. A sleeve is provided in fluid communication with the bore of the conduit, and is formed from materials characterized by a pore matrix through which vacuum or hydrodynamic draw is achieved in a process to promote stabilization and reducing bacterial colonization by draw fluid from an area around the surrounding the site of the device. The sleeve optionally has a distal nanotextured surface.

A fluid treatment system for a percutaneous cable and methods of assembly and use are described herein. In one aspect, the fluid treatment system includes a delivery tube comprising a distal end and a proximal end. The distal end is configured to surround at least a portion of the percutaneous cable. The percutaneous cable extends from within a patient to outside the patient through tissue at an exit site. The proximal end is connectable to a fluid source. Fluid from the fluid source is configured to be delivered to the exit site through the delivery tube. The fluid treatment system includes an anchor coupleable to the percutaneous cable to secure the percutaneous cable to the tissue at the exit site.

A device for connecting and transferring contents between a surgically created first orifice and a surgically created second orifice is provided. The device comprises a hollow body member and first and second tubular legs depending from the hollow body, and being adapted for insertion into the first and second surgically created orifices respectively. The device further comprises a cap for closing the hollow body and completing a sealed pathway between the tubular legs for passively conveying contents between the first and second surgically created orifices. Sealing features of the device are provided that in combination operate to keep the contents away from unwanted skin areas and/or provide an easy-to-use device.

The present invention relates to a an anti-thrombotic medical instrument and catheter medical instrument comprising: base with a port for connection to an infusion set; a catheter extending from the base, and comprises a main body of tubular configuration. a plurality of lateral conduits distributed along the length of the catheter; an elastomeric cover over each lateral conduit, said elastomeric cover opens with a fluid flow inside the catheter and closes when the fluid flow stops. Said lateral conduits have an angle in the range of 15° to 60° to the longitudinal axis of the catheter.

A tamper resistant catheter device preventing unauthorized access, while permitting authorized intravenous medications through an inlet port. The device comprises a catheter line retainer having a base supporting the catheter line, a lumen adaptor engaged with the catheter line, and a locking clamp for clamping the catheter line within the catheter line retainer. An installation tool is provided having a breakaway handle and a locking cap for covering the lumen adaptor. Finally, a slotted retaining sleeve is installed using the breakaway handle of the installation tool for engagement with the locking cap and around the lumen adaptor. The slotted retaining sleeve engages the locking clamp to block removal of the locking clamp from the line retainer. Once the slotted retaining sleeve and locking cap are installed, the breakaway handle is removed. A removal tool disengages the locking cap from the slotted retaining sleeve for authorized access.

A medical device configured to restrict medicament dispersion within a cerebrospinal fluid flow of the patient. The medical device including an implantable catheter having a distal end configured to be positioned within a flow of the cerebrospinal fluid, a proximal end, a body defining a lumen extending lengthwise along the implantable catheter configured to enable a flow of medicament from the proximal end to an infusion port located in proximity to the distal end, and a contoured surface defined by an exterior of the body in proximity to the infusion port configured to inhibit dispersion of the medicament within the cerebrospinal fluid.

A device for the uninterrupted administration of fluid to an animal body during a draw of bodily fluid, e.g., blood, is disclosed. A first fluid channel is configured to selectively transport IV fluid to an animal body and to draw a bodily fluid from the body. A sealing member for sealing a bodily fluid draw port defines a concave surface on a first end. The sealing member concave surface forms an interior surface portion of the first fluid channel. A connection member is configured to connect to a catheter to the first fluid channel and defines a concave distal end. A second fluid channel continuously provides IV fluid to a lumen coaxially located within the catheter. The concave surface and the concave distal end are shaped to create fluid flow patterns that quickly and completely remove residual bodily fluid remaining after a draw of bodily fluid is completed.

Devices and methods for transplanting cells in a host body are described. The cell comprises a porous scaffold that allows ingrowth of vascular and connective tissues, a plug or plug system configured for placement within the porous scaffold, and a seal configured to enclose a proximal opening in the porous scaffold. The device may further comprise a cell delivery device for delivering cells into the porous scaffold. The method of cell transplantation comprises a two step process. The device is incubated in the host body to form a vascularized collagen matrix around a plug positioned within the porous scaffold. The plug is then retracted from the porous scaffold, and cells are delivered into the vascularized space created within the porous scaffold.

A protection device for a porta catheter device installed into patient's body. The protection device has a flat rim which would be secured to the patient's body around the porta catheter installation site using a medically appropriate adhesive. A dome-shaped protector rises up from the flat rim. The dome-shaped protector can secure any creams or lidocaine applied to the site of the porta catheter. The smooth round shape of the dome-shaped protector prevents it from catching or bumping on clothing or objects in the environment, preventing painful snags. There are no holes or gaps in the protector to prevent leaking of the creams or lidocaine. The flat rim can be affixed about the porta catheter using adhesive or a magnet.
