Patent number: 8075531Abstract: The present invention is a modular implantable medical device that is used deliver materials or energy into a patient's physiology, or from one region of a patient's physiology to another. The device includes a port element with a passageway therethrough for directing and anchoring a conduit element in a desired location. Both elements can be adjusted during placement to maximize the safety, comfort, and efficacy of use. In one embodiment, the port element is comprised of two components such that the passage way is formed after the components are assembled. This modularity enables a large diameter section of the conduit to be advanced past the port location, and the port to be assembled about a smaller proximal section of the conduit, thereby establishing full contact between the port and conduit elements to anchor the device in an optimal position.Type: GrantFiled: July 16, 2008Date of Patent: December 13, 2011Assignee: Marvao Medical Ltd.Inventor: Christopher Davey

Patent number: 8066681Abstract: A monitor-driven intracranial catheter assembly including dual lumen catheter for monitoring intracranial pressure via a pressure sensor located in one lumen while simultaneously draining cerebrospinal fluid through another lumen. A third lumen can also be provided with a side port for receiving a stylet. The stylet is used as a stiffening agent to aid in advancing the catheter into the patient's brain. The pressure sensor is preferably a spectral modulation sensor that communicates with a photodetector apparatus by means of a single optical fiber, thus minimizing the diameter of the catheter. The photodetector is self-correcting for signal errors caused by temperature change, changes in intensity of the input light, and transmission losses within the optical apparatus.Type: GrantFiled: October 1, 1993Date of Patent: November 29, 2011Assignee: Edwards Life Sciences, Inc.Inventors: John P.

Patent number: 8048062Abstract: A catheter assembly and method for internally anchoring a catheter in a patient. According to one embodiment, the catheter assembly includes a catheter, a tubular fitting coupled to one end of the catheter, and an internal bolster coaxially mounted around the tubular fitting. The tubular fitting has a waist portion, and the internal bolster is secured thereto by a snap-fit. To internally anchor the catheter in a patient, one inserts the end of the catheter to which the fitting is coupled into the patient and then, while the fitting and its coupled end of the catheter are within the patient, inserts the internal bolster over the fitting until it snap-fits into place over the waist portion, thereby internally anchoring the catheter within the patient.Type: GrantFiled: December 30, 2005Date of Patent: November 1, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Mark L.

Patent number: 8043280Abstract: A releasable medical device connector comprises a connector fitting with a spin nut which connects to an adaptor. The connector fitting has at least one radially extending member with a variable radius cross section. The spin nut is disposed upon the connector fitting proximal of the radially extending member and is both axially slidable and rotatable upon the elongated body of the connector fitting. A screw thread within a proximal portion of the spin nut is used to secure the tapering portion of the connector fitting to an external thread disposed upon the adaptor. To release the connector, the spin nut is unscrewed from the adaptor and slid so that a distal receptacle of the spin nut engages the radially extending member of the connector fitting. With the spin nut and connector fitting engaged, the medical line can be released from the adaptor by twisting and pulling upon the spin nut.Type: GrantFiled: November 30, 2007Date of Patent: October 25, 2011Assignee: Venetec International, Inc.Inventor: Steven F.

Patent number: 8038643Abstract: The invention relates to a device for loading a patient connector for peritoneal dialysis with a closure plug. To permit an arbitrary number of disconnection/connection procedures with patient connectors that insert a sterile closure plug into the patient's abdominal connector during disconnection, a device for loading a patient connector for peritoneal dialysis with a closure plug is suggested, said device consisting of a housing containing a closure plug and of means for transferring the closure plug out of the device and into a patient connector. This permits loading, under sterile conditions, of a patient connector whose closure plug has already been used with a new closure plug. By loading a new closure plug, the push-button with which the closure plug is inserted is returned to its starting position, so that the patient connector is again available for a connection/disconnection procedure.Type: GrantFiled: January 27, 2005Date of Patent: October 18, 2011Assignee: Fresenius Medical Care Deutschland GmbHInventors: Wolfgang Biesel, Reinhold Reiter, Alain Veneroni
