Abstract: A system for securing a mask onto a subject's head is provided. The system may include a mask base, a mask latch, and a mask head strap. The mask base may be configured to support a gas delivery conduit for delivering gas to the subject. The mask latch may be pivotally coupled to the mask base about an axis extending generally laterally across the mask base. The mask head strap may be configured to be positioned around a subject's head and coupled to the mask latch such that rotation of the mask latch about the axis and relative to the mask base adjusts the mask head strap.

Abstract: In accordance with one embodiment of the present disclosure, an adjustable gas delivery system is provided. The system may include a face mask, an arm apparatus, and a gasket. The face mask may be configured to deliver gas to a subject, and may include a flexible cushion portion configured to interface with the subject's face and a rigid base portion configured to support the cushion portion, the rigid base portion including a gas inlet. The arm apparatus may be configured to deliver gas to the face mask. The arm apparatus may include a gas outlet having a cross-sectional area smaller than a cross-sectional area of the gas inlet of the base portion of the face mask. The gasket may couple the gas outlet of the arm apparatus with the gas inlet of the face mask. The gasket may be flexible such that the orientation of the face mask relative to the arm apparatus is adjustable.

Abstract: A noise-suppressing gas exhaust system for a gas delivery mask is provided. The system may include a face mask, an arm assembly, and a gas exhaust member. The face mask may be configured to interface with a subject's face. The arm assembly may be configured to support the face mask. The gas exhaust member may be coupled to the arm assembly and may include a single gas passageway extending therethrough. The gas passageway may extend from a first opening formed in a first side of the gas exhaust member to a second opening formed in a second side of the gas exhaust member. The first opening may have a cross-sectional area of about 0.01 square inches to about 0.03 square inches, and the second opening may have a substantially larger cross-sectional area than the cross-sectional area of the first opening.

Abstract: A system for adjusting a gas delivery mask is provided. The system may include a first housing portion, a first rim flexibly coupled to the first housing portion by a flexible member, a second housing portion coupled to the first housing portion, a second rim associated with the second housing portion, and a ball rotatably disposed between the first and second rims and having a gas passageway extending therethrough. The ball may be maintained in contact with both the first and second rims by a resiliency of the flexible member.

Abstract: A bone displacement assembly for use during a medical procedure including preparing soft bone includes a cannula and a probe that is removably inserted into the cannula. The probe includes a curved tip designed to mechanically displace soft bone and to prepare the bone tissue for subsequent treatment such as cement injection. The probe also includes a handle assembly that connects with the cannula and also includes one control device for independently rotating the distal tip and a second control device to independently translate the distal tip.

Abstract: A system for adjusting a gas delivery mask is provided. The system may include a base, an arm pivotally coupled to the base, and an intermediate member slidably coupled to both the base and the arm. The arm may include a first threaded portion, and the intermediate member may include a second threaded portion coupled to the first threaded portion. Rotation of the second threaded portion relative to the first threaded portion may slide the intermediate member along the arm and relative to the base such that the arm pivots relative to the base.
