| 20080214991 | CATHETER SYSTEM WITH ATTACHABLE CATHETER HUB - A hemodialysis catheter assembly adapted for use in a subcutaneous tunneling procedure incorporates a mechanism for securing the catheter hub member to the elongated catheter, and to provide the requisite fluid communication between fluid passages within the hub and the catheter lumens within the catheter. The catheter hub member may be connected to the elongated catheter after implantation of the catheter via a subcutaneous tunneling procedure. | 09-04-2008 |
| 20080214992 | CATHETER TUNNELING SYSTEMS, INSTRUMENTS AND METHODS - An instrument for facilitating insertion of a catheter through a subcutaneous tunnel includes a tunneling stylet defining a longitudinal axis and having leading and trailing ends, a bifurcated segment adjacent the leading end of the tunneling stylet and a releasable cover releasably mountable to the leading end of the tunneling stylet to substantially enclose the bifurcated segment. The bifurcated segment includes first and second elements adapted for reception within respective lumens of a catheter. The instrument may further include a dilation member which is releasably mountable to the leading end of the tunneling stylet in the absence of the releasable cover. The dilation member is dimensioned to generally increase an internal dimension of the subcutaneous tunnel. The first and second elements of the bifurcated segment each include an outer peripheral rib dimensioned to facilitate gripping engagement with an internal surface of respective lumens of the catheter. The first and second elements of the bifurcated segment may include a plurality of spaced outer peripheral ribs dimensioned to facilitate gripping engagement with internal surfaces of respective lumens of the catheter. In an alternative embodiment, the bifurcated segment is releasably mountable to the tunneling stylet. Systems and methods of use of the tunneling instrument are also disclosed. | 09-04-2008 |
| 20080214993 | CATHETER ADAPTER APPARATUS - A catheter adapter apparatus includes an adapter body. The adapter body includes a fluid source end adapted for connection to a fluid source and having an internal bore to transfer the fluids supplied by the fluid source, and a catheter end for connection to a catheter tube. The catheter end includes first and second members. Each of the first and second members is adapted for reception within corresponding lumens of the catheter tube. At least the first member defines an internal bore in fluid communication with the fluid source end to transfer the fluids supplied by the fluid source. The second member may define an internal bore in fluid communication with the internal bore of the fluid source end. The catheter adapter apparatus may further include a valve member associated with the adapter body. The valve member may be movable to selectively fluidly connect the internal bores of the first and second members with the internal bore of the fluid source end. The fluid source end of the adapter body may include a luer connector. | 09-04-2008 |
| 20090112167 | SHEATHLESS INSERTION STYLET SYSTEM FOR CATHETER PLACEMENT - A stylet instrument is positionable within a catheter to facilitate placement of the catheter during a surgical procedure. The stylet instrument has application in a hemodialysis procedure where the catheter is positioned via a subcutaneous tunneling technique. The stylet instrument includes a hub, first and second stylet members extending from the hub and operatively connected to permit positioning within corresponding lumens of a catheter, and securing means associated with the hub to releasably secure the catheter to the hub. The securing means includes at least one locking detent. | 04-30-2009 |
| 20090137944 | Medical system and catheter connector apparatus - A medical system for connecting a multiple lumen medical catheter to associated medical instrumentation includes a connector member defining a longitudinal axis and having a first end for releasable coupling to the medical catheter and a second end for coupling to medical instrumentation. A mounting segment is adjacent the first end of the connector member. The mounting segment includes first and second mounting elements extending in a general longitudinal direction and arranged in spaced relation, and being adapted for reception within respective lumens of the catheter. The first and second mounting elements define inner opposing surfaces. At least one of the opposing surfaces may have an irregular surface portion dimensioned to engage the septum wall of the catheter to facilitate gripping engagement with the septum wall to assist in coupling of the connector member with the catheter. | 05-28-2009 |
| 20090157045 | Guidewire Compatible Port and Method for Inserting the Same - An access port assembly having an attachable catheter allows for inserting a guidewire into the catheter to aid in the placement of the integral catheter while still attached to the access port assembly. A method is described for placing an access port fixedly attached to a catheter into a patient using a guidewire inserted into the catheter. | 06-18-2009 |
| 20100063513 | Tunneling System - A tunneling system includes an elongate tunneling member defining a longitudinal axis along at least a portion of a longitudinal length thereof. The elongate tunneling member has a first end and a second end. The second end of the elongate tunneling member includes a coupling segment adapted for securely engaging a catheter. | 03-11-2010 |
| 20100204635 | Catheter System With Attachable Catheter Hub - A hemodialysis catheter assembly adapted for use in a subcutaneous tunneling procedure incorporates a mechanism for securing the catheter hub member to the elongated catheter, and to provide the requisite fluid communication between fluid passages within the hub and the catheter lumens within the catheter. The catheter hub member may be connected to the elongated catheter after implantation of the catheter via a subcutaneous tunneling procedure. | 08-12-2010 |
