A detachable electrode and anchor utilized with electrode leads and leadless medical implants that enable explantation of the electrode while leaving the anchor in place. The detachable electrode and anchor utilizes a detachable mechanism that detachably couples the electrode to the anchor. Embodiments do not require removal of existing scar tissue before explantation, which minimize chances of internal bleeding at the extraction site. Embodiments also minimize impact on the vein in which the electrode lead travels by eliminating use of a necessarily larger diameter sheath that is utilized around the electrode lead to remove the electrode lead and attached anchor.

A moldable, bioresorbable, biocompatible, non-allergenic crosslinked collagen derivative dressing for the prevention of post extraction alveolar osteitis (dry socket) pain is disclosed along with methods for use of the gel. The dressing is placed at the time of surgery acting as a bone covering obtundant and physiologic scaffolding for the conduction of normal alveolar bone healing sequence of fibroblast ingrowth, blood vessel formation, and reossification of the extraction site defect. In one form, the dressing is a flowable, moldable, biocompatible, bioresorbable dressing prepared by reacting (i) a collagen derivative, such as gelatin or atelocollagen, and (ii) a non-cytotoxic crosslinking agent.

A submergible or non-submergible (“one stage”) screw-type implant for use in the immediate post-extraction site of a patient's tooth. In order to increase the ability of regenerated bone to anchor the implant, an upper portion of the implant has a preferably generally conical shape and has a plurality of spherical projections sintered to its outer surface to make it suitable for bone integration and retention. The lower portion of the implant has a cylindrical shape with threads extending over a portion thereof. A channel is located through the threads and is shaped so that one side forms a cutting edge that makes the lower portion of the implant self-tapping into the bone at the base of the tooth extension socket.

The invention relates to a method for evaluating efficacy of an antler, which takes the bifidobacterium in a gastrointestinal tract as representative of beneficial bacterium and takes staphylococcus as representative of harmful bacterium.The method objectively and quantitatively evaluates the influence of different extraction sites of antler alcohol extract on the growth and metabolism of microorganism in the gastrointestinal tract through obtaining a thermogram and other comprehensive information which can fully reflect the interaction process and has overall expression characteristics, screens the active site with the strongest bacterium-promoting action of the antler and inspects the bacteriostasis of the active side simultaneously. The method has simple operation, easy standardization and automation of the detection.

Embodiments are directed to managing and improving a drilling and completions process at a hydrocarbon extraction site, and to optimizing resource allocation at a hydrocarbon extraction site/region. In one scenario, a computer system accesses data generated by hardware sensors implemented by drilling and completion equipment at a hydrocarbon extraction site. The computer system formats the sensor data into a form readable by a data mining algorithm, and mines the formatted sensor data to identify characteristics related to the drilling and completion process. The computer system also accesses and integrates historical data related to the drilling and completion equipment at the hydrocarbon extraction site. The computer system then computes drilling and completion performance indicators that identify inefficiencies based on the characteristics identified for the equipment and based on the accessed historical data. Then, a remediation step is performed to resolve the identified inefficiency.

A bone repair material is described that is of putty-like consistency, particularly useful for repairing dental bony defects such as those caused by bone loss resulting from moderate or severe periodontitis, augmenting of bony defects of the alveolar ridge, filling tooth extraction sites, or sinus elevation grafting. The repair material includes a porous, resorbable particulate that is bone-derived or derived from bone-like hydroxyapatite or synthetic hydroxyapatite; and, a resorbable carrier, such as high molecular weight polysaccharides, such as hyaluronic acid. A high concentration of particulate in the putty enhances bone repair and requires a high concentration of carrier to retain the putty at the defect site. For a particulate density of about 1.2 g/cc such as PEPGEN P-15® Bone Graft, a preferred formulation comprises about 55% percent by weight of the putty suspended in a hyaluronic acid gel of about 1.4×10⁶ daltons molecular weight and a final concentration of about 56 mg/cc which material adheres to a bony periodontal defect and does not excessively expand or migrate from the defect when held in place by a conventional flap closure.

A method for increasing the distance between outer surface of tissue proximate to a surgical extraction site and a patient's sensitive body tissues comprising the infusion of a solution at a location of minimum distance between the extraction site and the sensitive body tissue until the accumulation of fluid distends the sensitive body tissue away from the extraction site.
