US 8,709,018 B2 · Non-balloon low profile feed device with insertion/removal tool

Abstract

A device for inserting a non-balloon gastrostomic device through an opening in the wall of the abdomen and stomach or other viscera of a patient is provided. The insertion device comprises a body, a stylus, and a trigger device being adapted to selectively maintain a selected position of the stylus relative to the body without the use of an external force. A method of inserting the gastrostomic device utilizing the insertion tool is also provided. In addition or alternatively, a gastrostomic device is provided including a hollow tube member and an enlarged resiliently deformable tip at one end of the tube member. The deformable tip is deformable between a first configuration and a second configuration, each configuration having a cross-sectional area. In addition or alternatively, a method is provided for forming the gastrostomic device using a disposable core.

Dependent claims

A device for inserting a non-balloon gastrostomic device through an opening in the wall of the abdomen and stomach or other viscera of a patient, the device comprising:

a body including a tapered aperture extending therethrough, with the body substantially enclosing the aperture and the aperture having a larger opening at one end than the other, with the body having a plurality of detents along its exterior surface and having an attachment member positioned at one end of the body configured to removably fix the body to an opening in a gastrostomic device;
a stylus having a proximal end and a terminal end, the terminal end being configured to extend a distance through the aperture of the body to deform a portion of a gastrostomic device fixed to the body;
and
a trigger device attached to the proximal end of the stylus and being adapted to selectively maintain a selected position of the terminal end of the stylus relative to the body without the use of an external force, the trigger device including at least one projection, with the projection being configured to engage one of the plurality of detents;
at least one ratchet arm attached to the trigger device to permit the at least one projection to move towards and away from engagement with the plurality of detents;
at least one release arm configured to release the at least one projection from engagement with the plurality of detents.

A device for inserting a non-balloon gastrostomic device through an opening in the wall of the abdomen and stomach or other viscera of a patient, the device comprising:

a body including an aperture extending therethrough and a plurality of detents along its exterior surface and an attachment member configured to removably attach the body to a gastrostomic device, with the attachment member having a locking feature for locking a gastrostomic device to the body and a tapered end for insertion into an opening in the device, with the tapered end serving to open a valve within the device;
a stylus having a proximal end and a terminal end, the terminal end being configured to extend a distance through the aperture of the body to deform a portion of a gastrostomic device attached to the body;
and
a trigger device attached to the proximal end of the stylus at a connection portion and being adapted to selectively maintain a selected position of the terminal end of the stylus relative to the body without the use of an external force, the trigger device further comprising at least one mating feature for engaging one of the plurality of detents;
and
a release mechanism for releasing the mating feature from the plurality of detents.
