Incised or injured tissue is treated by introducing material that encourages healing to desired depths within the tissue. Particularly, the invention provides treatment of an access channel to a blood vessel by introducing to the tissue a hemostatic material to a position that is located adjacent, but does not extend beyond, the vessel wall. In one aspect, the invention features a device for treating an incision channel through tissue and the wall of a body lumen. The device includes a member having a proximal portion constructed to remain outside the body and an elongate generally tubular distal portion that is constructed to be introduced axially into the channel and be moveable axially therein. A detector is disposed on the side of the tubular distal portion. The detector is adapted to detect a predetermined condition indicative of an axial position within the channel. A healing promoting substance is carried by the member and releasable from the member into the channel at a desired axial location relative to the location indicated by the detector.

A device for treating an incision channel that extends through tissue and the wall of a body lumen, comprising: a member having a proximal portion that remains outside the body and an elongate distal portion that is introduced axially into said channel, a detector disposed on the side of said distal portion to detect an axial location along said channel, a healing promoting substance having a desired axial length, being carried by the exterior of said member, and being releasable from said member into the channel at a desired axial position relative to said location detected by said detector and, a healing promoting substance locator mark on the proximal portion of said member remaining outside the body at select axial distance from said detector based on the axial length of said healing promoting substance for locating said substance at said desired axial position in said channel when the detector is at the axial location detected by said detector.
