A nasal assembly for delivering breathable gas to a patient includes a frame having an integrally formed first connector portion. A nozzle assembly includes a gusset or base portion and a pair of nozzles. At least one inlet conduit is structured to deliver breathable gas into the frame and nozzle assembly for breathing by the patient. A pair of second connector portions are removably and rotatably connected to respective first connector portions of the frame and are in communication with respective inlet conduits, e.g., directly or via angle connectors. A headgear assembly is removably connected to the pair of second connector portions and/or the angle connectors so as to maintain the frame and the nozzle assembly in a desired adjusted position on the patient's face.

A respiratory mask for use with a patient, and that is suited for use with children, includes a flexible cushion arranged to interface with and deliver air to the patient's nose. The cushion has a tube connection portion at one or both sides adjacent the patient's nares, the tube connection portion being arranged to connect to an air delivery tube. This location, plus the very low profile of the mask, allows a patient (e.g. an infant) to sleep on their face more comfortably. A more rigid support structure adjacent the cushion is provided to stabilize the cushion and prevent it from collapsing. Headgear is also provided and arranged for releasable attachment to the support structure.

The rim has a contour such that the portion thereof to be located between the ischium and the pubis extends distally further from an equator of the bearing surface than the contour to be implanted between the pubis and the illium and between the ischium and the illium.

A bone resection tool for resecting an end of a bone along a surface having a curvature comprises a guide, a cutting tool and a track follower. The guide is configured to be removably attached in a fixed position to the end of the bone. The guide is configured to include a track exhibiting a curvature generally corresponding to the curvature of the surface to be resected in the bone. The cutting tool includes a cutting face. The track follower is configured to couple to the cutting tool and cooperate with the track to facilitate reciprocation of the cutting tool relative to the guide to induce the cutting face to resect the bone along the surface having the curvature. A method for cutting a bone along a curved surface conforming to the curvature of a curved surface of the underside of a prosthetic component comprises the steps of incising the tissue surrounding the surface of the bone, positioning a guide alongside the surface of a bone to be cut, affixing the guide to the bone, interconnecting a cutter having a cutting face with the guide, maintaining the cutting face generally parallel to the tangent of the curved surface and traversing the cutting face along the bone while guiding the cutter along the track. The tissue incision incises the tissue surrounding the surface of the bone to be cut in a minimally invasive fashion. The positioned guide includes a track configured to assimilate the curvature of the curved surface of the underside of the prosthetic component.

An acetabular shell liner having a variable rim surface geometry, which improves range of motion of the femoral component within the liner and decreases the incidence of dislocation and subluxation, and methods of making and using the acetabular shell liner. Prosthetic devices, more particularly hip joint prostheses, containing the acetabular shell liner having a variable rim surface geometry are also provided.

An endoscope includes an insertion tube having a distal end and an imaging device with a steerable extension. The proximal end of the extension is attached to the distal end of the insertion tube. An endoscope includes an insertion tube having a distal end region and a rear-viewing imaging device at least partially disposed inside the distal end region. An endoscope includes an insertion tube having a distal end cap, an imaging device, and a link that couples the imaging device to the distal end cap of the insertion tube.

A shaving razor having a handle that defines a longitudinal axis, a shaving head that defines a transverse axis, a connector assembly, and a biasing element. The connector assembly couples the handle and the head so that the head can pivot upward and downward about its transverse axis and can also move toward and away from the handle with the transverse axis perpendicular to the longitudinal axis or oblique thereto. Preferably, the biasing element is separate and spaced apart from the connector assembly and biases the head into a rest position.

A bone resection guide, particularly for an ulna, utilizes anatomical reference points of the ulna to establish an optimal position for a prosthesis. The bone resection guide provides a guiding instrument that allows a surgeon to remove only bone that needs to be removed for precise placement of the end prosthesis. A method of resecting bone from the ulna in preparation of prosthetic implantation using the bone resection guide matches an elbow axis finder with a particular size of an ulna fossa of the patient. Once matched, a sized resection template, directly related to the shape of the prosthesis, is used as a resection guide. Incorporated into the bone resection guide are known anthropometric qualities when providing resection surfaces. This enhances the probable position of the implant.

A system for implanting an anchor into bone, the system comprising a curved cannulated guide for percautaneous insertion, having a proximal end and a distal end; a flexible drill insertable through the curved guide from the proximal end to the distal end, the flexible drill having a shaft having a flexible portion; and a flexible inserter for inserting a suture anchor into a bore at the anatomical site formed by the flexible drill, the flexible inserter having a shaft having a flexible portion, wherein the flexible portions of both the flexible drill and flexible inserter include a series of discrete, interlocking segments.

An apparatus for inserting a suture anchor into an internal anatomical site through a cannula, or percutaneously, has a curved hollow guide for insertion into the cannula and/or tissue. The guide has a proximal end and a distal end. The distal end has a “parabolic ” shape for engaging the intended anatomical site such as a glenoid. A flexible obturator is insertable through the curved guide from the proximal end to the distal end to facilitate insertion of the guide through the cannula. A flexible drill is insertable through the curved guide from the proximal to the distal end once the guide is in place. A flexible inserter is provided for inserting a suture anchor into a bore at the anatomical site formed by the flexible drill.
