摘要： A firm but pliable medical device for use as a bone graft substitute or bone graft extender retains its shape without the requirement of a containment device, such as a syringe. Because the device is solid, it is easy to locate or position in-vivo and, in the moist environment of the body, it will hold its shape well, for an extended time. Because the lyophilized pliable medical device is porous, it adsorbs blood and other beneficial cells containing body fluids, such as bone marrow, contributing to its superior bone repair efficacy in comparison to an analogous putty that has not been lyophilized. In addition these lyophilized pliable medical devices are easier to terminally steam sterilize than the analogous putty because there is no moisture present to boil and “blow-out” of the containment device (syringe). The glycerin that is present in the formulation lends pliability but has a low vapor pressure.
摘要翻译：用作骨移植物替代物或骨移植物延长剂的牢固但柔韧的医疗装置保持其形状，而不需要诸如注射器的容纳装置。因为该装置是固体，所以很容易在体内定位或定位，并且在身体的潮湿环境中，其将保持良好的形状，长时间。因为冻干的柔韧的医疗装置是多孔的，因此与没有被冻干的类似的腻子相比，它吸收含有体液如骨髓的血液和其它有益细胞，有助于其优异的骨修复功效。此外，这些冻干的柔韧的医疗设备比类似的油灰更容易终止蒸汽消毒，因为不存在水分以便将容器（注射器）煮沸和“吹出”。存在于制剂中的甘油具有柔韧性但具有低蒸气压。

摘要： The invention provides a variety of surgical instruments for forming a liquid jet, which are useful for performing a wide variety of surgical procedures. In some embodiments, the invention provides surgical liquid jet instruments having a pressure lumen and an evacuation lumen, where the pressure lumen includes at least one nozzle for forming a liquid jet and where the evacuation lumen includes a jet-receiving opening for receiving the liquid jet when the instrument is in operation. In some embodiments, the pressure lumen and the evacuation lumen of the surgical liquid jet instruments are constructed and positionable relative to each other so that the liquid comprising the liquid jet, and any tissue or material entrained by the liquid jet can be evacuated through the evacuation lumen without the need for an external source of suction. The invention also provides a variety of surgical liquid jet instruments that are constructed and configured specifically for use in a surrounding liquid environment or a surrounding gaseous environment. The invention also provides a variety of surgical liquid jet instruments that are rotatably deployable from an undeployed position, for insertion into the body of a patient, to a deployed position, in which there is a separation distance between the liquid jet nozzle and the jet-receiving opening that defines a liquid jet path length. The invention also provides surgical methods utilizing the inventive surgical liquid jet instruments, and methods for forming components of the surgical liquid jet instruments.

摘要： The present invention provides a series of devices for performing surgical procedures utilizing electrodes for performing electrocautery on a tissue of the body of a patient. The invention includes, in one aspect, a series of devices comprising surgical instruments providing at least one electrode for performing electrocautery, and, in another aspect, provides a method for cutting and cauterizing tissue with a surgical instrument. In yet another aspect, the invention involves a method for detecting the location of a bleeding vessel in a liquid-filled, visually monitored surgical field of a patient and for electrocauterizing the vessel to stop the bleeding before visualization of the surgical field is compromised. Preferred surgical instruments according to the invention also include operable components for forming a liquid cutting jet for cutting or ablating tissue of a patient and/or for providing a rotating, tissue contacting component for cutting, grinding, ablating, etc. tissue during a surgical procedure. Some surgical instruments, according to the invention, include one or more liquid conducting lumen therein for transporting and/or removing a liquid from a surgical operating field, which lumen, in some cases, are selectively coated with a layer of an electrically insulating material so that certain, selected, uncoated regions of an external surface of the lumen can act as an electrocautery electrode of the instrument.
