A surgical instrument guide assembly includes a main guide portion that includes a shaft portion extending along a longitudinal axis and a body portion extending along the longitudinal axis, and a proximal end of the shaft portion is disposed at a distal end of the body portion. The main guide portion further includes a first lumen and a second lumen that each extends along the longitudinal axis from a proximal end at a proximal end of the body portion to a distal end at a distal end of the shaft portion. A seal portion is coupled to the proximal end of the body portion of the main guide portion, and the seal portion includes a first port and a second port formed in a seal wall of the seal portion. The seal portion is selectively displaceable from a first position to a second position.

A device for cardiac surgery is disclosed. The device for cardiac surgery includes an aortic root retractor frame, an introducer, and one or more suture locking apparatuses. The device for cardiac surgery also includes an actuator for releasing the aortic root retractor frame, as well as a deployment mechanism for fully expanding the aortic root retractor frame. Multiple suture locking apparatuses used for releasable locking and unlocking of suture during a cardiac surgery procedure may be included in the device for cardiac surgery.

The seal portion is selectively displaceable from a first position to a second position.

A surgical port is disclosed. The surgical port has a cannular channel. The surgical port also has one or more suture slots in communication with the cannular channel. The surgical port further has a pair of cam grips for each of the one or more suture slots, each pair of cam grips comprising opposing gripping arms configured to allow suture to be pulled through the opposing gripping arms in a direction away from the cannular channel and to resist suture movement in a direction towards the cannular channel.

A suturing device for minimally invasive surgery includes a state indicator coupled to a portion of a needle. When the needle displaces between a first needle position and a second needle position along a needle axis in a first actuation cycle, the needle rotates about the needle axis from a first rotational position to a second rotational position such that the state indicator transitions from a first visual indication to a second visual indication. When the needle displaces between the first needle position and the second needle position along the needle axis in a second actuation cycle, the needle rotates about the needle axis from the second rotational position to a third rotational position, and the state indicator transitions from the second visual indication to a third visual indication.

A surgical sizer sound, comprising an actuatable shaft. The surgical sizer sound also comprises an angled shaft coupled to the actuatable shaft. The surgical sizer sound also comprises a sizer coupler comprising a guide tip and a limit, pivotably coupled to the angled shaft and a sizer, removably coupled to the sizer coupler.

A retractor member includes a body portion extending along a longitudinal axis and being at least partially defined by a first lateral perimeter edge and a second lateral perimeter edge that each extends parallel to the longitudinal axis. The body portion additionally includes an upper surface and a lower surface that each extends between the first lateral perimeter edge and the second lateral perimeter edge. A first lateral support portion is coupled to the body portion at a first location at or adjacent to the first lateral perimeter edge, and a second lateral support portion is coupled to the body portion at a second location at or adjacent to the second lateral perimeter edge. A first coupling portion is disposed at a top end portion of the first lateral support portion and a second coupling portion is disposed at a top end portion of the second lateral support portion.

The surgical port further has a pair of cam grips for each of the one or more suture slots, each pair of cam grips comprising opposing gripping arms configured to allow suture to be pulled through the opposing gripping arms in a direction away from the cannular channel and to resist suture movement in a direction towards the cannular channel.

An endoscope port having a housing is disclosed. The housing of the endoscope port may include a channel passing therethrough, and a hub which may include a first roller and a second roller. The endoscope port may further include an entrance at an end of the channel, and an exit at an opposite end of the channel. The endoscope port may be configured such that when an actuator moves in a first rotational direction, a first roller moves in a second rotational direction, and a second roller moves in the first rotational direction.
