Sean Farrell - Fresno CA, US

Assignee:

Fresenius Medical Care Holdings, Inc. - Waltham MA

International Classification:

A61M 1/28

US Classification:

604 29

Abstract:

A catheter assembly includes a tubular member having a first connector at its distal end for coupling with the proximal end of a catheter. The tubular member has at least one external guide wire that is slidably contained inside the tubular member. The at least one external guide wire has an attachment member for attaching to an internal guide wire catch that is slidably contained inside the catheter, whereby manipulation of the guide wire causes motion in the distal end of the catheter. The catheter assembly can be articulated within an internal cavity of a patient to more completely and accurately fill and/or drain the cavity during, for example, peritoneal dialysis.

Inventors:

Sean Farrell - Fresno CA, US

Assignee:

Fresenius Medical Care Holdings, Inc. - Waltham MA

International Classification:

F15D 1/00

US Classification:

13756501

Abstract:

A system including a machine and a cassette that moves fluid from one source to another for use in dialysis. The machine includes at least a first set of pressure imposing valve actuators, said valve actuators being pneumatically operated and substantially adjacently disposed, and a cassette receiving portion. The cassette includes a housing adapted to be removably placed in the cassette receiving portion of the machine. The housing includes at least one inlet port adapted to be fluidly coupled to a fluid source, and at least one outlet port. The housing further includes an inlet manifold and a collection chamber, and at least one fluid pathway fluidly coupled to the two. In use, the fluid pathway disposed substantially adjacent the first set of valve actuators such that sequential actuation of the valve actuators moves a fluid through the pathways to the collection chamber.

International Classification:

A61M 1/28

US Classification:

604 28, 604 29

Abstract:

This disclosure relates to medical fluid cassettes and related systems and methods. In certain aspects, a medical fluid cassette includes a base having a first region and a second region, a first membrane overlying the first region of the base, and a second membrane overlying the second region of the base. The second membrane is configured to rebound away from the base when a force used to press the second membrane toward the base is released.

US Classification:

604 29

Abstract:

A medical fluid pumping system that includes a medical fluid pumping machine that includes an actuator and a medical fluid cassette that can be disposed within a cassette enclosure of the medical fluid pumping machine. A member is disposed within a fluid pump chamber of the medical fluid cassette and is magnetically attracted to the actuator such that the member and the actuator can be coupled together when the cassette is disposed within the cassette enclosure.

International Classification:

F04B 43/12

US Classification:

417 53, 4174772

Abstract:

This disclosure relates to medical fluid delivery sets and related systems and methods. In some aspects of the invention, a medical fluid cassette includes a plunger slidably disposed within a recess of a base of the cassette such that a substantially liquid-tight seal is maintained between the plunger and the base as the plunger slides axially within the recess. The plunger and the base cooperate to at least partially define a fluid pump chamber. When the plunger is displaced in a first direction, fluid is forced out of the fluid pump chamber, and when the plunger is displaced in a second direction, fluid is drawn into the fluid pump chamber.

International Classification:

A61N 1/368
A61B 5/0408

Abstract:

Systems, methods, and devices are described herein for evaluation, adjustment, and delivery of adaptive cardiac therapy. The systems, methods, and devices may utilize electrical heterogeneity information to determine and/or select one or more pacing settings and pacing type or configurations for a plurality of different heart rates. The adaptive cardiac therapy may deliver cardiac therapy at selected pacing settings such as, for example, A-V and/or V-V intervals, according to a presently measured heart rate and switch between left ventricular-only or biventricular cardiac pacing therapy also according to the presently measured heart rate.
