Abstract
Abstract An everting catheter system (11) which includes an elongated outer catheter (13) having an outer catheter lumen and an opening, an elongated inner catheter (15) movable in the outer catheter lumen and having the inner catheter lumen adapted to receive an elongated instrument and an everting element (17) coupled to the outer catheter and the inner catheter. With movement of the inner catheter in the outer catheter lumen, the everting element can be everted through the opening of the outer catheter. A controller (53) is coupled to the inner catheter for moving the inner catheter in the outer catheter lumen and for moving the instrument in the inner catheter lumen.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
113 words
An everting catheter system which includes an elongated outer catheter having an outer catheter lumen and an opening, an elongated inner catheter movable in the outer catheter lumen and having an inner catheter lumen adapted to receive an elongated instrument and an everting element coupled to the outer catheter and the inner catheter whereby with movement of the inner catheter in the outer catheter lumen the everting element can be everted through the opening in the outer catheter and characterized by: a controller coupled to the inner catheter for moving the inner catheter in the outer catheter lumen and for moving the instrument in the inner catheter lumen relative to the inner catheter.
Claim 2
Dependent Claim
44 words
A system as defined in claim 1 wherein the controller includes a driving device for moving the instrument longitudinally in the inner catheter lumen relative to the inner catheter and the controller is bodily movable to move the inner catheter in the outer catheter.
Claim 3
Dependent Claim
58 words
A system as defined in claim 2 wherein the controller includes a housing coupled to a proximal end portion of the inner catheter whereby the inner catheter can be moved in the outer catheter lumen by movement of the housing, said housing having a passage adapted to receive the instrument, said passage communicating with the inner catheter lumen.
Claim 4
Dependent Claim
72 words
A system as defined in claim 3 wherein the passage in the housing has an axis, said housing includes a rotatable section rotatable generally about the axis of the passage, said driving device is carried by the rotatable section and is capable of gripping the instrument so that rotation of the rotatable section rotates the instrument relative to the inner catheter, and means for releasably coupling the housing to the inner catheter.
Claim 5
Independent Claim
50 words
A system as defined in any of claims 2 to 4 wherein the driving device includes an endless movable member having a region engageable by a thumb of an operator to impart a manual driving force to the driving device for moving the instrument longitudinally in the inner catheter lumen.
Claim 6
Independent Claim
29 words
A system as defined in claims 1, 2 or 3 wherein at least a portion of the controller is movable to rotate the instrument relative to the inner catheter.
Claim 7
Independent Claim
85 words
A system as defined in any of claims 1 to 6 wherein the controller includes a drive wheel and a secondary wheel, each of said wheels having a peripheral surface, said wheels being rotatably mounted with the peripheral surfaces in generally confronting relationship and adapted to receive the instrument therebetween so that upon rotation of the drive wheel the instrument can be moved longitudinally in the passage, and at least one of said peripheral surfaces of said wheels having a groove for receiving the instrument.
Claim 8
Dependent Claim
21 words
A system as defined in claim 7 including a plurality of spaced projections on the peripheral surface of the drive wheel.
Claim 9
Dependent Claim
139 words
A controller for moving an elongated medical instrument in a catheter comprising: a housing having a passage extending therethrough which is adapted to receive an elongated medical instrument, said housing including a mounting section adapted to be coupled to a catheter, a drive section and an elongated handle section which is adapted to be manually grasped; a drive wheel and a secondary wheel, each of said wheels having a peripheral surface, said wheels being rotatably mounted on the drive section with the peripheral surfaces in generally confronting relationship and adapted to receive the instrument therebetween so that upon rotation of the drive wheel the instrument can be moved longitudinally in the passage; a manual drive for manually rotating the drive wheel; and at least one of said peripheral surfaces of said wheels having a groove for receiving the instrument.
Claim 10
Dependent Claim
48 words
A controller as defined in claim 9 wherein both said drive wheel and said secondary wheel define said groove, each of said drive wheel and said secondary wheel has an annular peripheral recess and the controller includes first and second members received in the annular peripheral recesses, respectively.
Claim 11
Dependent Claim
27 words
A controller as defined in claim 10 wherein the first and second members include first and second spaced alignment tabs for guiding the instrument between said wheels.
Claim 12
Dependent Claim
37 words
A controller as defined in claim 9 wherein the passage has an axis and the controller includes means for rotatably coupling the drive section to the mounting section for rotation generally about the axis of the passage.
