Appl. No.:

10/074532

Inventors:

Brian Connell - Evanston IL, US
Bill Griswold - Bristol WI, US
Raf Castellanos - Roselle IL, US
Tom Johnson - Gurnee IL, US

Assignee:

Baxter International Inc. - Deerfield IL
Baxter Healthcare S.A. - Zurich

International Classification:

A61M 1/00

US Classification:

604 30

Abstract:

Apparatuses and methods for providing sterile connection during, for example, dialysis therapy. The present invention provides a connector and a cap therefore that easily and readily attaches to a dialysate container and a catheter inserted into a patient's peritoneal cavity. The connector and the cap enable the dialysate to readily transport between the container and the peritoneal cavity while minimizing the potential of contamination therein due to, for example, handling during use. The connector includes a shell that encloses a cap. The cap houses a slit septum and also includes a sealed disinfectant within an interior receptacle. When the catheter or catheter set attaches to the cap, the seal breaks and the disinfectant spreads over the threads between the catheter set and the cap.

International Classification:

A61M 1/00

US Classification:

604 30

Abstract:

Apparatuses and methods for providing audio, visual and/or tactile feedback during assembly of two mating medical fluid connectors and a retention force are provided. The invention includes a first connector defining a first lumen and a second connector defining a second lumen. The first and second connectors are threaded together to enable the first lumen to initially communicate fluidly with the second lumen after the first and second connectors are engaged. The first connector defines a first engaging member and the second connector defines a second engaging member, the engaging members mating to provide (i) feedback indicating that a mating of the first and second connectors is at least substantially complete and (ii) a retention force tending to hold the first and second connectors together. An improved apparatus for releasing a sealed disinfectant is also provided.

International Classification:

A61M 37/00

US Classification:

604 616

Abstract:

In general, multiple embodiments of a catheter/fistula needle to bloodline connection assurance device, which secures and strengthens a connection between an extension tube end of a catheter or fistula needle and a bloodline are provided. A first embodiment of the assurance device is configured to be compatible with any industrial catheter/fistula needle female luer connector and is specifically configured for use with a bloodline connector having locking clips which are biased slightly outwardly from the bloodline connector. The first embodiment of the assurance device is cylindrical and includes clamshell halves that open rotatably about at least one hinge. The first embodiment of the assurance device includes an upper, threaded portion and a lower housing portion. The interior wall of the upper portion defines a plurality of barbs configured to engage with distal or moveable ends of the locking clips. Each locking clip is biased slightly outwardly to enable the distal or moveable end of the locking clip to fit between two respective barbs.

International Classification:

A61B 17/34
A61M 13/00

Abstract:

A trocar for peritoneal dialysis is disclosed herein. An example trocar includes a conduit having two or more parallel lumens and a head connected to a first end of the conduit. The head includes two (or more) parallel lumens that are aligned respectively with the parallel conduit lumens and includes at least one of a gasket or a seal for each lumen. The trocar also includes a coupler connected to the head. The coupler includes two (or more) parallel lumens that are aligned respectively with the parallel lumens of the head. The coupler includes a coupling mechanism for each lumen for securing surgical tools in place after insertion into a patient. The trocar may also include an obturator having a shaft that is removably inserted through the coupler, head, and conduit to protrude from a second end of the conduit.

Abstract:

Methods and apparatuses for peritoneal catheter placement are disclosed herein. An example method includes using a puncture device to create an access hole to a patient's peritoneal cavity. The puncture device includes a lumen that enables a guidewire to be inserted into the peritoneal cavity. The puncture device is then replaced with a catheter, which is inserted along the guidewire. A surgical seal is next applied to connect the catheter to adjacent patient muscle tissue. After the guidewire is removed, a tunneling device creates a pathway through fat tissue to anchor the catheter. An end of the tunneling device is aligned with an external piercing device to pierce the patient's skin from the outside, creating a catheter exit hole. An end of the catheter is connected to the tunneling device and pulled through the exit hole, thereby enabling the catheter to be connected to peritoneal dialysis tubing for a treatment.
