Filed:

Feb 11, 1993

Appl. No.:

8/016435

Inventors:

Jeffrey T. Barnes - Norwood MA
J. Erik Moore - Charlestown MA

Assignee:

Biosyss Corporation - Braintree MA

International Classification:

A61B 500

US Classification:

128672

Abstract:

A blood pressure instrument and method in which analog blood pressure waveform signals are digitized and stored and used to determine blood pressure parameters to make physiological measurements based upon pattern recognition using information empirically obtained from clinical measurements. In a preferred embodiment, the analog waveform signals are obtained non-invasively using an external wrist-mounted displacement transducer.

International Classification:

A61B 17/16
A61B 17/06

Abstract:

A medical device configured to form one or more holes within a bone of a patient may include a handle assembly including a housing, a lever rotatably coupled to the housing, and a sheath extending distally from the housing, the handle assembly including a spring biasing the lever toward an initial or intermediate position; and a bone punch including an elongate shaft, a head at a proximal end of the elongate shaft, and a piercing tip at a distal end of the elongate shaft configured to be driven into the bone. The elongate shaft may be slidably disposed within the sheath in a first position when the lever is in the initial or intermediate position. Translation of the bone punch distally within the sheath from the first position to a second position may cause a distal end of the lever to rotate away from the housing to an extended position.

International Classification:

A61M 5/145
A61M 5/142

Abstract:

Embodiments of the present disclosure relate to techniques, processes, devices or systems for pump devices. In one approach, a wearable drug delivery device, may include a reservoir configured to store a fluid, the reservoir comprising a housing including an outer wall defining an interior chamber, and a drive mechanism for driving the fluid from the reservoir. The drive mechanism may include a plunger received in the interior chamber of the reservoir, a leadscrew extending from the plunger, and a clutch mechanism threadably engaged with the leadscrew, wherein the clutch mechanism is configured to allow the leadscrew to pass through the clutch mechanism when disengaged and is configured to grip the leadscrew when engaged such that the clutch mechanism rotates to advance the leadscrew and the plunger into the reservoir.
