Transcutaneous inserter for low-profile infusion sets
First Claim
1. A low-profile inserter for an angled infusion set having a cannula assembly including a cannula housing and a cannula extending from the housing to be inserted subcutaneously, the low-profile inserter comprising:
- an inserter housing having a bottom wall;
a retainer slidably connected to the inserter housing for movement between retracted and extended positions in a direction substantially parallel with the bottom wall, the retainer being adapted to releasably receive the cannula assembly; and
a base member connected to the inserter housing, the base member having a lower surface that is adapted to contact an outer skin surface, the lower surface and bottom wall forming an acute angle, whereby the cannula can be inserted subcutaneously at said acute angle with respect to the skin outer surface.

Abstract
A low-profile inserter for an angled infusion set comprises an inserter housing having a bottom wall, a retainer slidably connected to the inserter housing for movement between retracted and extended positions in a direction substantially parallel with the bottom wall, and a base member connected to the inserter housing. The retainer is adapted to releasably receive a cannula assembly, including a cannula connected to a cannula housing. The base member has a lower surface that is adapted to contact a skin outer surface. The lower surface and bottom wall together form an acute angle. With this arrangement, the cannula can be inserted subcutaneously at the acute angle with respect to the skin outer surface.

14. An inserter for an infusion set having a cannula assembly including a cannula housing and a cannula extending from the housing to be inserted subcutaneously, the inserter comprising:
-
an inserter housing;
a retainer slidably connected to the inserter housing for movement between retracted and extended positions, the retainer being adapted to releasably receive the cannula assembly;
a biasing member connected between the retainer and the inserter housing for biasing the retainer toward the extended position; and
a first release lever pivotally mounted to the inserter housing, the first release lever including a first end portion exposed through the housing for manipulation by an operator and a second end portion for engagement with the retainer to thereby hold the retainer in the retracted position, whereby pivotal movement of the first release lever in a first rotational direction causes disengagement of the second end portion and the retainer to thereby release the retainer.
