Abstract
A surgical drain including an introducer having a central axis, a proximal end, and a distal end. The proximal end disposed along the central axis and configured to couple to a drain. The distal end having a blunt distal tip and the introducer at least partially tapering from the proximal end to the distal end, wherein the introducer has a length of 30 cm or greater.
Claims19
A surgical drain introducer comprising:
- a central axis, a proximal end, and a distal end, the proximal end disposed along the central axis and opposite the distal end, the proximal end configured to couple to a drain, and the distal end having a blunt distal tip, the introducer constantly tapering from an area proximate the proximal end to an area proximate the distal end such that a diameter of the introducer decreases continuously along a length of the introducer from the proximal end to the distal end;
- and
- a middle portion disposed between the proximal end and the distal end and including the mid-point of the surgical drain introducer equidistance from the proximal end and distal end, the middle portion having an arc extending through the mid-point resulting in the distal end being offset from the central axis,
- wherein the introducer has a length of 30 cm or greater and the introducer is comprised of a rigid material to prevent bending of the introducer,
- wherein the introducer includes one or more apertures disposed proximate the distal end, the one or more apertures extending axially in the proximal direction along the central axis.

A surgical drain introducer comprising:
- a central axis, a proximal end, a middle portion, and a distal end, the proximal end disposed along the central axis and opposite the distal end, the proximal end configured to couple to a flexible drain and the distal end offset from the central axis and having a blunt distal tip, the introducer constantly tapering from the proximal end to the distal end such that a diameter of the introducer continuously tapers and decreases along a length of the introducer from the proximal end, through the middle portion, and to the distal end;
- a middle portion disposed between the proximal end and the distal end and including the mid-point of the surgical drain introducer equidistance from the proximal end and distal end, the middle portion having an arc extending through the mid-point resulting in the distal end being offset from the central axis;
- one or more apertures disposed proximate the distal end, the one or more apertures extending axially in the proximal direction along the central axis and being radially and axially offset from one another;
- one or more gripping portions disposed between the proximal end and the distal end, the one or more gripping portion including a plurality of ridges;
- and
- the flexible drain coupled to the introducer,
- wherein one or more ferrules disposed on the proximal end and extending radially from the central axis are friction fit with an inner surface of the drain to resist decoupling the drain from the introducer,
- wherein the introducer has a length greater than or equal to 30 cm, a maximum diameter of at least 0.5 cm, and curves in a radial direction along a portion of the introducer, and
- wherein the introducer is comprised of a rigid material to prevent bending of the introducer and the introducer includes a maximum diameter disposed adjacent the proximal end,
- wherein one or both of a portion of the middle portion and a portion of the distal end curves away from the central axis.
