Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
136 words
A drive assembly of an ablation device connectable to a catheter assembly including a rotatable drive shaft, the drive assembly comprising: a housing; and a connector including a first coupling rotatably connected to the housing about an axis of rotation, the first coupling including means for releasably connecting the drive shaft to the housing for rotating the drive shaft relative to the housing, and the first coupling including a fluid tight seal to allow fluid to flow between the housing and the catheter assembly; and the connector including a second coupling fixedly connected to the housing and including means for releasably connecting a portion of the catheter assembly to the housing, the second coupling retaining the portion of the catheter assembly from rotation relative to the housing while the first coupling rotates with the drive shaft.
Claim 2
Dependent Claim
136 words
A drive assembly of an ablation device connectable to a catheter assembly including a rotatable drive shaft, the drive assembly comprising: a housing; and a connector including a first coupling rotatably connected to the housing about an axis of rotation, the first coupling including means for releasably connecting the drive shaft to the housing for rotating the drive shaft relative to the housing, and the first coupling including a fluid tight seal to allow fluid to flow between the housing and the catheter assembly; and the connector including a second coupling fixedly connected to the housing and including means for releasably connecting a portion of the catheter assembly to the housing, the second coupling retaining the portion of the catheter assembly from rotation relative to the housing while the first coupling rotates with the drive shaft.
Claim 3
Dependent Claim
33 words
A connector in accordance with claim 1, wherein the first coupling is slidably connected to the housing to allow the position of the first coupling to be shifted along the axis of rotation.
Claim 4
Dependent Claim
26 words
A connector in accordance with claim 1, wherein the first coupling includes an internally threaded connector capable of threadably connecting the drive shaft to the housing.
Claim 5
Dependent Claim
21 words
A connector in accordance with claim 1, wherein the second coupling includes two generally opposing flexible jaws extending from the housing.
Claim 6
Dependent Claim
29 words
A connector in accordance with claim 4, wherein each jaw includes a tab engagable with the catheter assembly to connect the portion of the catheter assembly to the housing.
Claim 7
Dependent Claim
20 words
A connector in accordance with claim 5, wherein the jaws are formed at least in part from a resilient plastic.
