Claim 8
Independent Claim
98 words
A device for the removal of tissue from, and the application of medicaments to, a biological conduit, comprising: a rotatable and axially translatable applicator, the applicator including: an outer surface; a distal end and a proximal end; an interior reservoir for containing a medicament; at least one delivery path connecting the interior reservoir to the surface of the applicator; and a drive cable attached to the proximal end of said applicator for imparting rotational and translational motion to the applicator, whereby the medicament contained in the reservoir is deliverable to the biological conduit when the applicator is rotated.
Claim 9
Independent Claim
98 words
A device for the removal of tissue from, and the application of medicaments to, a biological conduit, comprising: a rotatable and axially translatable applicator, the applicator including: an outer surface; a distal end and a proximal end; an interior reservoir for containing a medicament; at least one delivery path connecting the interior reservoir to the surface of the applicator; and a drive cable attached to the proximal end of said applicator for imparting rotational and translational motion to the applicator, whereby the medicament contained in the reservoir is deliverable to the biological conduit when the applicator is rotated.
Claim 10
Dependent Claim
13 words
The device of claim 7 wherein the biological conduit is a blood vessel.
Claim 11
Dependent Claim
14 words
The device of claim 8 wherein the blood vessel is a coronary blood vessel.
Claim 12
Dependent Claim
13 words
The device of claim 7 wherein the delivery path is of capillary dimensions.
Claim 13
Dependent Claim
13 words
The device of claim 10 wherein the biological conduit is a blood vessel.
Claim 14
Dependent Claim
14 words

Claim 15
Independent Claim
137 words
A method for localized application of medicaments within a biological conduit, the method comprising the steps of: providing a device that includes: a rotatable and axially translatable applicator, the applicator including an outer surface; a proximal end; a distal end; an interior medicament containing reservoir; at least one delivery path connecting the interior medicament reservoir to the surface of the applicator; and a drive cable attached to the proximal end of said applicator for imparting rotational motion to said applicator, inserting the device in the biological conduit so that the applicator is adjacent to the treatment area; and rotating the applicator at a speed sufficient to force the contained medicament to the surface of the applicator and onto the surface of the biological conduit, whereby the medicament contained in the reservoir is delivered to the biological conduit.
Claim 16
Independent Claim
137 words
A method for localized application of medicaments within a biological conduit, the method comprising the steps of: providing a device that includes: a rotatable and axially translatable applicator, the applicator including an outer surface; a proximal end; a distal end; an interior medicament containing reservoir; at least one delivery path connecting the interior medicament reservoir to the surface of the applicator; and a drive cable attached to the proximal end of said applicator for imparting rotational motion to said applicator, inserting the device in the biological conduit so that the applicator is adjacent to the treatment area; and rotating the applicator at a speed sufficient to force the contained medicament to the surface of the applicator and onto the surface of the biological conduit, whereby the medicament contained in the reservoir is delivered to the biological conduit.
Claim 17
Dependent Claim
13 words
The method of claim 13 wherein the biological conduit is a blood vessel.
Claim 18
Dependent Claim
14 words
The method of claim 14 wherein the blood vessel is a coronary blood vessel.
Claim 19
Dependent Claim
13 words
The method of claim 13 wherein the delivery path is of capillary dimensions.

Claim 22
Independent Claim
147 words
A method for surgically intervening within a biological conduit, the method comprising the steps of: providing a device that includes: a rotatable and axially translatable applicator, the applicator including an outer surface; a proximal end; a distal end; a cutting means at the distal end of the applicator; an interior medicament containing reservoir; at least one delivery path connecting the interior medicament reservoir to the surface of the applicator; and a drive cable attached to the proximal end of said applicator for imparting rotational and translational motion to said applicator, inserting the device in the biological conduit so that the applicator is adjacent to the treatment area; and rotating the applicator at a speed sufficient to force the contained medicament to the surface of the applicator and onto the surface of the biological conduit, whereby the medicament contained in the reservoir is delivered to the biological conduit.
Claim 23
Independent Claim
147 words
A method for surgically intervening within a biological conduit, the method comprising the steps of: providing a device that includes: a rotatable and axially translatable applicator, the applicator including an outer surface; a proximal end; a distal end; a cutting means at the distal end of the applicator; an interior medicament containing reservoir; at least one delivery path connecting the interior medicament reservoir to the surface of the applicator; and a drive cable attached to the proximal end of said applicator for imparting rotational and translational motion to said applicator, inserting the device in the biological conduit so that the applicator is adjacent to the treatment area; and rotating the applicator at a speed sufficient to force the contained medicament to the surface of the applicator and onto the surface of the biological conduit, whereby the medicament contained in the reservoir is delivered to the biological conduit.
