Handle for vacuum delivery device

A fetal heart rate electrode assembly, a connector for use therewith and a cable assembly including a housing assembly configured for engagement with the connector. The electrode assembly includes a drive knob configured and located for selective extension of a fetal scalp electrode beyond a distal end thereof. The connector comprises a rotationally omnidirectional contact assembly disposed within a dielectric housing including an annular groove on the exterior thereof The housing assembly includes longitudinally resiliently biased pin contacts for end face contact with the contacts of the connector disposed within an inner housing of the housing assembly having an O-ring and an annular retention element positioned to respectively wipe the exterior of the connector housing and grasp the connector housing at the annular groove when the connector is inserted thereinto. A system and methods of use are also disclosed.

A urodynamic catheter incorporating at least one balloon adjacent a distal end thereof and associated with a pressure lumen extending to a proximal end to be placed external to the body of a patient and usable with a transducer housing including a pressure transducer and a mechanism for alternatively venting an air column defined by the assembled pressure lumen and transducer housing to the ambient environment and closing the air column and charging it with air while reducing volume of the air column. One embodiment includes two, separately-chargeable balloons and a bladder fill tube, another embodiment includes a single balloon and a fill tube, and yet another embodiment, suitable for use as a reference catheter to measure abdominal pressure, includes only a single balloon and omits the fill tube. A novel catheter architecture and assembly technique are also disclosed, as are methods of using the inventive catheter.

Urodynamic catheter and methods of fabrication and use

A vacuum extractor for use in childbirth is described. The vacuum extractor includes a handle and a vacuum cup with a force sensor coupled to the vacuum extractor. The force sensor measures the traction force applied between the vacuum cup and the handle for assisting the birthing attendant in applying an appropriate traction force. The force sensor may also include a slipping mechanism which causes the length of the force sensor to distinctly increase if the applied traction force exceeds a certain level such as twenty pounds. Thus, the birthing attendant may feel the slipping and thus determine that the traction force has exceeded the certain value.

Traction force sensing vacuum extractor

A hand-held fetal vacuum extractor combines a pump and handle into a single hand-held unit. This enables a single operator, such as a doctor, to control vacuum using a vacuum pump, and apply traction to a fetus using a single hand. A handle, having a surface for gripping, is connected to a fetal vacuum cup for being suctioned onto a fetal head. A vacuum pump is connected to the handle and includes an activation surface for activating the vacuum pump. The vacuum pump is fluidly coupled to a the vacuum cup and fetal head. The grip surface of the handle and the activation surface of the pump are in such proximity, during operation, that a single human hand can simultaneously grasp the grip surface and contact the activation surface.

The fetal contact cup portion of a fetal vacuum cup has an inside surface which, when applied to a fetal head, defines a fetal contact chamber with the fetal head. One end of a tube is attached to the fetal contact cup such that vacuums within the tube are applied within the fetal contact cup. The other end of the tube can be connected with a vacuum source and with a handle. The tube has a very small average outside diameter compared with conventional fetal vacuum tubes. Thus the fetal vacuum cup is less intrusive during insertion and is more easily maneuverable, especially when the fetus is malpresenting in, for example, the high occipitoposterior or high occipitolateral positions. The average outside diameter of the tube may be, for example, less than 150 mils and has a finger grip that compression fits into a recess defined by the outer surface of the fetal contact cup for a lower profile and easy positioning of the fetal contact cup onto the flexion point of the fetal head. During traction, however, the finger grip pulls out of the recess for more efficient traction. The fetal contact cup may have a soft lip for contacting the fetal head. Furthermore, the tubing may have markings to indicate proper positioning of the fetal vacuum cup over the flexion point.
