Abstract
A device and method for the localized treatment of vasculature with drugs and medicaments is described herein. Centrifugal force is used to drive a material from a reservoir to the outer surface of the application device and thereby deliver the treatment substance to the chosen area.
Claims24
A device for 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 and translational motion to the applicator,
- whereby the medicament contained in the reservoir is deliverable to the biological conduit when the applicator is rotated.
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.
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.
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.
