A catheter grip and catheter assembly are provided. The catheter grip includes a body portion adapted to extend circumferentially around a catheter shaft of the catheter assembly to facilitate gripping of the catheter shaft by a user. The catheter grip also includes a head portion through which the catheter shaft can be fed and a biasing mechanism. The biasing mechanism biases the body portion and the head portion away from one another.

1. A catheter grip for a catheter shaft, said catheter grip comprising: a body portion adapted to extend circumferentially around said catheter shaft, said body portion comprising two opposed substantially planar gripping surfaces that are resiliently compressible towards one another to facilitate gripping of said catheter shaft by a user, and opposed longitudinal walls that extend between edges of said opposed substantially planar gripping surfaces;a head portion through which said catheter shaft can be fed;a biasing mechanism comprising two laterally spaced walls extending between said body portion and said head portion, said laterally spaced walls being resiliently deformable away from one another as said body portion and said head portion are moved towards one another such that, on release, said laterally spaced walls bias said body portion and said head portion away from one another; andwherein said catheter grip is adapted to be removably associated with said catheter shaft. 2. A catheter grip according to claim 1, wherein each of said laterally spaced walls comprises a weakened or diminished portion at or around a longitudinal mid-point thereof such that, in use, as said body portion is forced towards said head portion said laterally spaced walls flex outwardly to provide said biasing. 3. A catheter grip according to claim 2, wherein each of said laterally spaced walls comprises a weakened or diminished portion adjacent the head portion and/or the body portion. 4. A catheter grip according to claim 1, wherein said opposed gripping surfaces are disposed in the same plane as said opposed laterally spaced walls. 5. A catheter grip according to claim 1, wherein said head portion comprises a collar. 6. A catheter grip according to claim 5, wherein said head portion additionally comprises a shaft feed extending from said collar through which said catheter shaft is fed. 7. A catheter grip according to claim 6, wherein said shaft feed is disposed on a feed insert that is adapted to be inserted into said collar of said head portion. 8. A catheter grip according to claim 7, wherein said feed insert comprises a tubular portion having at least one ridge, said tubular portion being received by said collar of said head portion, an abutment having an abutment surface which abuts said collar of said head portion, and said shaft feed which extends from an outer face of said abutment. 9. A catheter grip according to claim 1, wherein said body portion, head portion and biasing mechanism are integral with one another to provide said catheter grip. 10. A catheter grip according to claim 1, wherein inner surfaces of one or more of said opposed, substantially planar gripping surfaces of said body portion comprise longitudinally extending alignment ribs. 11. A catheter grip according to claim 1, wherein said opposed, substantially planar gripping surfaces of said body portion comprise ridges extending laterally there across. 12. A catheter assembly comprising: a catheter shaft having a drainage outlet at a proximal end thereof and a catheter tip and at least one drainage inlet at a distal end thereof;a catheter grip removably associated with said catheter shaft, said catheter grip comprising a body portion that extends circumferentially around said catheter shaft, said body portion comprising two opposed substantially planar gripping surfaces that are resiliently compressible towards one another to facilitate gripping of said catheter shaft by a user, and opposed longitudinal walls that extend between edges of said opposed substantially planar gripping surfaces, and a head portion through which said catheter shaft can be fed;a biasing mechanism comprising two laterally spaced walls extending between said body portion and said head portion, said laterally spaced walls being resiliently deformable away from one another as said body portion and said head portion are moved towards one another such that, on release, said laterally spaced walls bias said body portion and said head portion away from one another. 13. A catheter assembly according to claim 12, wherein each of said laterally spaced walls comprises a weakened or diminished portion at or around a longitudinal mid-point thereof such that, in use, as said body portion is forced towards said head portion said laterally spaced walls flex outwardly to provide said biasing. 14. A catheter assembly according to claim 13, wherein each of said laterally spaced walls comprises a weakened or diminished portion adjacent the head portion and/or the body portion. 15. A catheter assembly according to claim 12, wherein said drainage outlet comprises a catheter funnel. 16. A catheter assembly according to claim 12, wherein said at least one drainage inlet of said catheter shaft comprises at least one eyelet. 17. A catheter assembly according to claim 12, wherein inner surfaces of one or more of said opposed, substantially planar gripping surfaces of said body portion comprise longitudinally extending alignment ribs. 18. A catheter assembly according to claim 12, wherein said opposed, substantially planar gripping surfaces of said body portion comprise ridges extending laterally there across. 19. A catheter assembly according to claim 12, wherein said opposed, substantially planar gripping surfaces are disposed in the same plane as said opposed laterally spaced walls.
