Apparatus and method for local application of polymeric material to tissue
First Claim
Patent Images
1. A method of applying polymeric, non-fluent material to mammalian tissue, comprising:
- applying an initially entirely fluent, pre-polymeric material to the tissue by emitting the pre-polymeric material from an emission element located on an applicator; and
applying to the material actinic light from an emitter of actinic light located on the applicator for a period of time sufficient to convert the material to a polymeric, non-fluent condition.

Abstract
An apparatus is provided for applying to a surface of mammalian tissue including soft, living tissue an initially fluent material and then activating the material by exposure to an energy source. The material may be a liquid capable of polymerization to a non-fluent state by exposure to actinic light. The device, and methods that may be practiced in association with the device, enable a wide range of medical conditions to be treated including, for example, the application of a barrier to, soft tissue to prevent post-surgical adhesions.

21. A method of aiming a fluent delivery device and for irradiating fluent material delivered by the device, comprising:
-
providing a delivery and activating device having an applicator constructed and arranged to deliver fluent material in a predetermined pattern, the device having an emitter that emits electromagnetic radiation in a substantially corresponding pattern; preliminary irradiating a tissue surface with light in the predetermined pattern using the light pattern as a guide to orient the device at a selected location with respect to the tissue; thereafter delivering the fluent material onto the tissue at the location in the predetermined pattern; and thereafter emitting electromagnetic radiation from the emitter onto the fluent material to activate the material to convert it to a non-fluent state. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A method of applying, to mammalian tissue, a polymeric, non-fluent material, comprising:
-
applying an initially entirely fluent, pre-polymeric material to the tissue by emitting the pre-polymeric material from an emission element located on an applicator; and applying to the material actinic light from an emitter of actinic light located on the applicator for a period of time sufficient to convert the material to a polymeric, non-fluent condition.

33. A method of applying a polymeric, non-fluent material to a surface of tissue internally of a mammal, comprising:
-
applying percutaneously an initially entirely fluent, pre-polymeric material to a tissue surface internally of a mammal, the material being activatable to a non-fluent, polymeric condition by exposure to actinic light; and thereafter applying to the material actinic light for a sufficient length of time to effect in situ conversion of the material from a pre-polymeric, fluent to a polymeric, non-fluent condition.
