Abstract

A medical device including an elongate member extending from a proximal end toward a distal end, the elongate member having a lumen with a longitudinal axis, a hub portion towards the proximal end of the elongate member and configured for a user to hold and manipulate a position of the elongate member, a base portion including a first groove and a second groove separated by an opening, and two wings disposed towards a distal end of the medical device, the two wings being opposite each other across the longitudinal axis and on opposite sides of the base portion, wherein, the two wings are configured to move in relation to the longitudinal axis and wherein each wing has an elongate slot having a closed first end at a location between the base portion and a peripheral end of the wing.

First claim

What is claimed is:

1. A medical device comprising:
an elongate member extending from a proximal end toward a distal end, the elongate member having a lumen with a longitudinal axis;
a first proximal assembly towards the proximal end of the elongate member;
a second proximal assembly cooperating with the first proximal assembly, the second proximal assembly comprising:
a base portion comprising a groove having a gap and an opening, the base portion being configured to cooperate with a portion of the first proximal assembly; and
two wings being opposite sides of the base portion, the two wings being configured to move in relation to the longitudinal axis of the elongate member to change the gap of the groove, the two wings extending from a proximal end of the first proximal assembly.

2. The medical device of claim 1 , wherein each wing has an elongate slot having a closed first end at a location between the base portion and a peripheral end of the wing.

3. The medical device of claim 1 , wherein each of the two wings include a textured surface.

4. A method of forming a medical device comprising:
providing a first medical device portion comprising:
an elongate member;
a stem disposed towards a proximal end of the first medical device portion and proximal the elongate member, the stem comprising a protruding portion extending from one side of a stem portion; and
a lumen extending through the elongate member and the stem; and

positioning a second medical device portion over the stem so that the second medical device portion at least partially surrounds a portion of the first medical device portion, the second medical device portion comprising:
a base portion with a groove having a gap; and
two wings extending from the base portion, the wings being opposite each other on opposite sides of the base portion, the two wings being configured to move in relation to the longitudinal axis to change the gap of the groove.

5. The method of claim 4 , wherein positioning the second medical device portion over the stem, further comprises mounting the second medical device portion to the stem of the first medical device portion.

6. The method of claim 4 , wherein the base portion is formed of a polymer.

7. The method of claim 4 , wherein each wing of the two wings comprises a first portion angularly orientated in relation to a second portion, the second portion extending to and forming the peripheral end.

8. The method of claim 7 , wherein the elongate slot of each wing extending over at least a portion of each of the first portion and the second portion.

9. The method of claim 4 , wherein each of the two wings include a textured surface.

10. The method of claim 4 , wherein each of the two wings include ridges.

11. The method of claim 4 , wherein the base portion further comprises a second groove disposed from the first groove by an opening.

12. The method of claim 4 , wherein the two wings are integral with the base portion.

13. The method of claim 4 , wherein the stem comprises a slot.
