An adhesive device for biomedical applications is provided comprising a support and one or more water insoluble compounds of structure 1 wherein B is an oligomer derived from a polyester, polyether, polyalkylene glycol, polysilicone or polycarbonate with a MW<10,000 g/mol, Linker L is a urethane, urea bond, or amide bond; Linker L' is a urethane or urea bond, A is a chain extender of Mw≤3000 g/mol comprising substituted or unsubstituted alkyl, cycloalkyl and/or aromatic groups, W is a terminal adhesive benzene-1,2-diol derivative or a terminal adhesive benzene-1,2,3-triol derivative, m is 0 or 1; and n is 0, 1, 2, 3 or 4 or a cross-linked polymer formed from said compounds. The compound(s) have a Tg lower than 25° C.

Adhesive device for biomedical applications and methods of use thereof

Systems and methods are provided for assessing nasal deviation and symmetry via the processing of facial surface data. Facial surface data may be processed to determine a nasal deviation measure indicative of a lateral deviation between a nasal midline and a facial midplane. The facial surface data may also be processed to determine a measure of nasal symmetry associated with a selected nasal surface region, such as an aesthetic subunit. Nasal deviation and symmetry information based on both measures may then be presented. In some example implementations, a single nasal symmetry measure is generated and present for a given nasal surface region. Reference surface data characterizing a reference symmetrical facial shape and having a defined facial direction relative to a coordinate system may be employed to align the facial surface data prior to the determination of the nasal deviation and nasal symmetry measures.

The present disclosure provides a deep orbital access retractor (DOAR) device which includes a manipulable body section including a compressible handle having a size and shape to be manipulated by at least two (2) digits of a clinician. A flexible head section having two (2) arms with each arm having a distal end and a proximal end, with the distal ends of the arms spaced apart forming a gap there-between at a distal tip section. A flexible flange material envelops and encloses the two arms and the gap and extends around a periphery of the flexible head section. A flexible diaphragm is attached to and extends between the two arms to provide a generally spoon-shaped flexible head section. The flexible head section is linked to the compressible handle section with the linkage being configured such that upon compression of the handle section the arms articulate with respect to each other thereby causing narrowing of the flexible head section to allow for insertion into the orbit and positioning between soft tissue and bone while the flexible diaphragm remains in sufficient tension to not obstruct the view of the operator into the orbit. When compression is released the flexible diaphragm develops sufficient tension and rigidity for applying sufficient force to retract the orbital contents of a patient to allow access to orbital walls.

An apparatus for slicing a cartilage sample includes a rear cartilage support cup, a cartilage clamp, a front cartilage support, a cartilage receiving region, and a cartilage cutting element. The cartilage clamp has first and second clamp members spaced apart from and aligned in a clamping direction transverse to a longitudinal axis. The cartilage receiving region is bounded by the first and second clamp members, the front cartilage support, and the rear cartilage support cup. The cartilage cutting element is spaced rearwardly from the front cartilage support by a cartilage slice thickness, the cartilage cutting element being movable across the cartilage receiving region in a cutting direction transverse to the longitudinal axis.

Cartilage slicing apparatus and methods therefor

The present disclosure discloses a bone stabilization device (also referred to as a bone tape), which includes a composite flexible construct including a rigidifiable biocompatible sheet structure having first and second opposed surfaces. A biocompatible cement is located on the first surface. In use the composite flexible construct is applied to a bone with the cement contacted directly to the bone. The cement is made of a material that, once adhered to the bone, is curable to mechanically and/or ionically bond to the sheet structure and to chemically bond to the bone to achieve a permanent bond. The bone tape allows simultaneous alignment and stabilization of multiple articulated fragments for successful 3D reconstruction of shattered bones. Initial flexibility and translucency provided by the bone tape can facilitate the temporary stabilization and alignment adjustment of multiple fragments, prior to permanent rigid bonding.
