Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
102 words
A catheter assembly, comprising: an elongate shaft having a proximal end and a distal end, the shaft defining a lumen therethrough; a burr deflector disposed at the distal end of the shaft, the burr deflector including a burr engaging surface; an elongate drive shaft extending through the lumen, the drive shaft having a proximal end and a distal end; and a burr disposed at the distal end of the drive shaft, the drive shaft and burr being shiftable relative to the burr deflector between a first position and a second position, wherein the burr is transversely shifted relative to the burr deflector.
Claim 2
Dependent Claim
102 words
A catheter assembly, comprising: an elongate shaft having a proximal end and a distal end, the shaft defining a lumen therethrough; a burr deflector disposed at the distal end of the shaft, the burr deflector including a burr engaging surface; an elongate drive shaft extending through the lumen, the drive shaft having a proximal end and a distal end; and a burr disposed at the distal end of the drive shaft, the drive shaft and burr being shiftable relative to the burr deflector between a first position and a second position, wherein the burr is transversely shifted relative to the burr deflector.
Claim 3
Dependent Claim
30 words
A catheter assembly in accordance with claim 1, wherein the burr engaging surface is disposed at an angle greater than zero degrees relative to the length of the elongate shaft.
Claim 4
Dependent Claim
33 words
