Abstract

The devices and methods relate to devices for stabilizing and/or positioning tissue (e.g., heart) within a surgical area. The device may include an articulating arm and a tissue stabilizing member. The device may include one or more stabilizing segments disposed along at least a portion of the length of the articulating arm. Each stabilizing segment may be configured to compress and expand with respect to an internal channel of the arm. The articulating arm may be configured to move between a fixed state and movable state based on a state of the one or more stabilizing segments. In the fixed state, the one or more stabilizing segments may be compressed against the internal channel. In the movable state, the one or more stabilizing segments may be expanded with respect to the internal channel.

Claims20

Dependent claims

A device for stabilizing tissue, comprising:

an articulating arm having a first end, a second end, and a length there between;
one or more channels disposed along at least the length of the articulating arm, the one or more channels including an internal channel disposed along at least the length of the articulating arm;
one or more stabilizing segments disposed along at least a portion of the length of the articulating arm, each stabilizing segment being configured to compress and expand with respect to the internal channel;
a plurality of ports disposed on the internal channel within each stabilizing segment;
and
a tissue stabilizing member disposed at the second end of the articulating arm,
wherein:
the articulating arm is configured to move between a fixed state and movable state based on a state of the one or more stabilizing segments;
in the fixed state, the one or more stabilizing segments is compressed against the internal channel, and
in the movable state, the one or more stabilizing segments are expanded with respect to the internal channel.

A device for stabilizing tissue, comprising:

an articulating arm having a first end, a second end, and a length there between;
one or more channels disposed along at least the length of the articulating arm, the one or more channels including an internal channel disposed along at least the length of the articulating arm;
one or more stabilizing segments disposed along at least a portion of the length of the articulating arm, each stabilizing segment being configured to compress and expand with respect to the internal channel;
a plurality of stabilizing particles disposed within each stabilizing segment;
and
a tissue stabilizing member disposed at the second end,
wherein:
the articulating arm is configured to move between a fixed state and movable state based on a state of the one or more stabilizing segments;
wherein in the fixed state, the one or more stabilizing particles are compressed against the internal channel by the one or more stabilizing segments, and
wherein in the movable state, the one or more stabilizing particles are released within each stabilizing segment by the one or more stabilizing segments being expanded with respect to the internal channel.
