Abstract
Abstract A manually operable pressure switch is used to activate an inflation device in order to pressurize an inflatable member such as that found on a dilatation catheter. By operating the pressure switch, the physician simultaneously operates a timer which will measure and display the elapsed time of the inflation and deflation cycle.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
155 words
A timing system for measuring the time elapsed during an inflation cycle of a medical procedure, comprising: a catheter having a proximal end and a distal end, said proximal end having an inflation device connected thereto, and said catheter having an inflatable member near its distal end; an inflation lumen within said catheter providing fluid communication between said inflation device and said inflatable member, said inflation device operable to pressurize and depressurize said inflatable member; a timer for measuring elapsed time; a manually operable pressure switch operably associated with said inflation device, said pressure switch having an increase-pressure button which is actuated manually to initiate operation of said timer when said increase-pressure button is deactivated; and means for displaying the elapsed time so that after said inflation device pressurizes said inflation lumen and said inflatable member with fluid, said timer is manually activated to measure elapsed time during said inflation cycle of the medical procedure.
Claim 2
Dependent Claim
155 words
A timing system for measuring the time elapsed during an inflation cycle of a medical procedure, comprising: a catheter having a proximal end and a distal end, said proximal end having an inflation device connected thereto, and said catheter having an inflatable member near its distal end; an inflation lumen within said catheter providing fluid communication between said inflation device and said inflatable member, said inflation device operable to pressurize and depressurize said inflatable member; a timer for measuring elapsed time; a manually operable pressure switch operably associated with said inflation device, said pressure switch having an increase-pressure button which is actuated manually to initiate operation of said timer when said increase-pressure button is deactivated; and means for displaying the elapsed time so that after said inflation device pressurizes said inflation lumen and said inflatable member with fluid, said timer is manually activated to measure elapsed time during said inflation cycle of the medical procedure.
Claim 3
Dependent Claim
32 words
The timing system of claim 1, wherein said timer for measuring elapsed time does not start timing until the pressure in said inflatable member is equal to or greater than atmospheric pressure.
Claim 4
Dependent Claim
26 words
The timing system of claim 1, wherein said timer for measuring elapsed time does not begin timing until the pressure in inflatable member exceeds zero atmospheres.
Claim 5
Dependent Claim
40 words
The timing system of claim 1, wherein said timer for measuring elapsed time will automatically reset to zero when the pressure in said inflatable member is less than a predetermined pressure level at the time said pressure switch is actuated.
Claim 6
Dependent Claim
30 words
The timing system of claim 1, wherein said timer begins to measure time after the pressure in inflatable member equals a predetermined pressure threshold and the pressure switch is deactivated.
Claim 7
Dependent Claim
33 words
The timing system of claim 1, wherein said timer resets to zero each time said increase-pressure button is actuated when the pressure in said inflatable member is less than a predetermined pressure threshold.
Claim 8
Dependent Claim
14 words
The timing system of claim 1, wherein said timer operates in an analog mode.
Claim 9
Dependent Claim
14 words
The timing system of claim 1, wherein said timer operates in the digital mode.
Claim 10
Dependent Claim
28 words
The timing system of claim 1, wherein said timer for measuring elapsed time will automatically reset to zero when said increase-pressure button is activated at any pressure level.
Claim 11
Dependent Claim
33 words
The timing system of claim 1, wherein said timer for measuring elapsed time will automatically reset to zero when said increase-pressure button is activated at any pressure level below a predetermined pressure threshold.
Claim 12
Dependent Claim
169 words
A timing system for measuring the time elapsed during an inflation cycle of a medical procedure, comprising: a catheter having a proximal end and a distal end, said proximal end having an inflation device connected thereto, and said catheter having an inflatable member near its distal end; an inflation lumen within said catheter providing fluid communication between said inflation device and said inflatable member, said inflation device operable to pressurize and depressurize said inflatable member; a timer for measuring elapsed time; a manually operable pressure switch attached to said inflation device, said pressure switch actuated manually to simultaneously initiate operation of said inflation device to pressurize said inflatable member, said inflation device automatically stopping when the pressure in said inflatable member reaches zero after starting from a negative pressure; and means for displaying the elapsed time so that as said inflation device pressurizes said inflation lumen and said inflatable member with fluid, said timer is manually activated to measure elapsed time during said inflation cycle of the medical procedure.
