Total Claims: 18
Claim 1
Independent Claim
149 words
A balloon catheter system, comprising: (a) a balloon catheter, the balloon catheter including; (i) an elongate shaft having a proximal end, a distal end and an inflation lumen extending therethrough; (ii) an inflatable balloon connected to the distal end of the shaft and in fluid communication with the inflation lumen; and (iii) a manifold connected to the proximal end of the shaft, the manifold having an inflation port, the inflation port being in fluid communication with the inflation lumen; (b) an inflation device connected to the inflation port, the inflation device including; (i) a barrel in fluid communication with the inflation lumen; (ii) a plunger movably disposed in the barrel; (iii) a connection port disposed on the inflation device for connection to the manifold on the catheter; characterized in that the barrel has an internal volume less than 5 cc and an internal diameter of less than 0.25 inches.
Claim 2
Dependent Claim
44 words
A balloon catheter system as in claim 1 wherein the inflation device includes a prep port connected thereto, the prep port being in fluid communication with the inflation lumen of the catheter when the connection port is connected to the manifold of the catheter.
Claim 3
Dependent Claim
19 words
A balloon catheter system as in claim 1 wherein the inflation device is fixedly connected to the inflation port.
Claim 4
Dependent Claim
19 words
A balloon catheter system as in claim 1 wherein the inflation device is releasably connected to the inflation port.
Claim 5
Dependent Claim
26 words
A balloon catheter system as in claim 2, further including: (c) a seal connected to the prep port for sealing the inflation device during balloon inflation.
Claim 6
Dependent Claim
31 words
A balloon catheter system as in claim 5, further including: (d) a pressure transducer mounted on the catheter and being in fluid communication with the inflation lumen to measure pressure therein.
Claim 7
Dependent Claim
20 words
A balloon catheter system as in claim 6, further including: (e) a pressure display operably connected to the pressure transducer.
Claim 8
Dependent Claim
18 words
A balloon catheter as in claim 7, further including: (f) a timer display attached to the pressure display.
Claim 9
Dependent Claim
17 words
A balloon catheter system as in claim 7 wherein the pressure display is an electronic analog display.
Claim 10
Dependent Claim
26 words
A balloon catheter system as in claim 8 wherein the pressure display is an electronic analog display and the timer display is an electronic digital display.
Claim 11
Dependent Claim
15 words
A balloon catheter system as in claim 5 wherein the seal is a removable cap.
Claim 12
Dependent Claim
14 words
A balloon catheter system as in claim 5 wherein the seal is a valve.
Claim 13
Dependent Claim
19 words
A balloon catheter system as in claim 1, further including: (c) a first lock mechanism connected to the barrel.
Claim 14
Dependent Claim
28 words
A balloon catheter system as in claim 13 wherein the first lock mechanism includes a biasing member which causes the first lock mechanism to normally engage the plunger.
Claim 15
Dependent Claim
73 words
A balloon catheter system as in claim 13 wherein the first lock mechanism includes a threaded portion, the plunger includes a threaded portion, and the threaded portion on the first lock mechanism engages the threaded portion on the plunger such that the plunger may be longitudinally fixed relative to the first lock mechanism or may be longitudinally displaced relative to the first lock mechanism by rotating the plunger or disengaging the threaded portions.
Claim 16
Dependent Claim
49 words
A balloon catheter as in claim 13 wherein the first lock mechanism includes a collet which releasably engages the plunger such that the plunger may be longitudinally fixed relative to the first lock mechanism or may be longitudinally displaced relative to the first lock mechanism by disengaging the collet.
Claim 17
Dependent Claim
19 words
A balloon catheter system as in claim 13, further including: (d) a second lock mechanism connected to the plunger.
Claim 18
Dependent Claim
114 words
A balloon catheter system as in claim 17 wherein the first lock mechanism includes a threaded portion, the plunger includes a threaded portion, the threaded portion on the first lock mechanism engages the threaded portion on the plunger such that the plunger may be longitudinally fixed relative to the first lock mechanism or may be longitudinally displaced relative to the first lock mechanism by rotating the plunger or disengaging the threaded portions; and the second lock mechanism includes a collet which releasably engages the plunger such that the plunger may be longitudinally fixed relative to the second lock mechanism or may be longitudinally displaced relative to the second lock mechanism by disengaging the collet.
