Vibratory mucosa-removing tool

Claim 2

For use in connection with introduction of an implant into a mucosa-lined body cavity in the form of a tubular vessel, mucosaengaging means having an elongated portion of a substantially uniform cross-sectional dimension small enough for insertion into the tubular vessel into engagement with the mucosa lining, said elongated portion of said mucosa-engaging means having at its exterior surface which is adapted to engage the mucosa lining a means for removing the mucosa lining in response to movement of said means at said exterior surface of said elongated portion with respect to the mucosa lining, and vibrating means operatively connected with said mucosa-engaging means for vibrating the latter to provide at said means at said exterior surface of said elongated portion of said mucosa-engaging means a vibratory movement derived from said vibrating means to remove with said means at said exterior surface of said elongated portion of said mucosa-engaging means a mucosa lining engaged by said means at said exterior surface of said elongated portion of said mucosa-engaging means.

Claim 3

The combination of claim 1, said vibrating means being operatively connected with said mucosa-engaging means for reciprocating the latter back and forth along said axis.

Claim 4

The combination of claim 2 and wherein said means at said exterior surface of said elongated portion of said mucosa-engaging means has an irregular exterior surface provided with edges which engage the mucosa to remove the latter during vibratory movement of said means at said exterior surface of said elongated portion of said mucosa-engaging means.

Claim 5

The combination of claim 3 and wherein the body cavity is the lumen of an elongated tubular part of the body, and said elongated portion of said mucosa-engaging means having a diameter small enough to be received in the lumen with the exterior surface of said mucosa-engaging means circumferentially surrounded by and engaging the mucosa lining all around the axis of said mucosa-engaging means so that during vibratory movement of the latter the mucosa is circumferentially removed entirely around the axis of the lumen over a length thereof corresponding to the length of said mucosa-engaging means.

Claim 6

The combination of claim 4 and wherein said vibrating means is electrically operated.

Claim 7

The combination of claim 5 and wherein said electrically operated vibrating means has an elongated conductor adapted to be connected with a source of electricity.

Claim 8

The combination of claim 5 and wherein said vibrating means is battery driven.

Claim 9

The combination of claim 3 and wherein said mucosa-engaging mEans has a stem operatively connected with said vibrating means and said elongated portion extending perpendicularly from said stem and adapted to be received in the body cavity.

Claim 10

The combination of claim 8 and wherein said stem and elongated portion of said mucosa-engaging means provide the latter with an L-shaped configuration.

Claim 11

For use in connection with introduction of an implant into a mucosa-lined body cavity, mucosa-engaging means having a size and configuration suited for insertion into the body cavity into engagement with the mucosa lining, vibrating means operatively connected with said mucosa-engaging means for vibrating the latter, and said mucosa-engaging means responding to the vibratory movement derived from said vibrating means to remove a mucosa lining engaged by said mucosa-engaging means, said mucosa-engaging means having an elongated configuration and has an exterior mucosa-engaging surface surrounding a longitudinal axis of said mucosa-engaging means, said vibrating means being operatively connected with said mucosa-engaging means for reciprocating the latter back and forth along said axis, said mucosa-engaging means having an irregular exterior surface provided with edges which engage the mucosa to remove the latter during vibratory movement of said mucosa-engaging means, said mucosa-engaging means having a stem operatively connected with said vibrating means and an elongated portion extending perpendicularly from said stem and sdapted to be received in the body cavity, said mucosa-engaging means having a pair of said elongated portion extending perpendicularly from said stem in opposite directions and having a common axis so that said mucosa-engaging means is of a T-shaped configuration and is adapted to be situated with said oppositely directed elongated portions thereof in cavity portions which extend in opposition directions from said stem for simultaneously removing mucosa from a pair of body cavity portions between which said stem is located.

Claim 12

For use in connection with introduction of an implant into a mucosa-lined body cavity, mucosa-engaging means having a size and configuration suited for insertion into the body cavity into engagement with the mucosa lining, vibrating means operatively connected with said mucosa-engaging means for vibrating the latter, and said mucosa-engaging means responding to the vibratory movement derived from said vibrating means to remove a mucosa lining engaged by said mucosa-engaging means, said mucosa-engaging means having an elongated configuration and has an exterior mucosa-engaging surface surrounding a longitudinal axis of said mucosa-engaging means, said vibrating means being operatively connected with said mucosa-engaging means for reciprocating the latter back and forth along said axis, said mucosa-engaging means having an irregular exterior surface provided with edges which engage the mucosa to remove the latter during vibratory movement of said mucosa-engaging means, said mucosa-engaging means having a stem operatively connected with said vibrating means and an elongated portion extending perpendicularly from said stem and sdapted to be received in the body cavity, said mucosa-engaging means having a pair of said elongated portion extending perpendicularly from said stem in opposite directions and having a common axis so that said mucosa-engaging means is of a T-shaped configuration and is adapted to be situated with said oppositely directed elongated portions thereof in cavity portions which extend in opposition directions from said stem for simultaneously removing mucosa from a pair of body cavity portions between which said stem is located.

Claim 13

The combination of claim 3 and wherein said mucosa-engaging means is in the form of a single elongated body connected at one end to said vibrating means and having an extension projecting coaxially from said one end and provided with the exterior irregular surface for engaging and removing mucosa.
