A biopsy needle guide comprises a base, a flexible strap, a bracket, a needle guide bracket, and several locking mechanisms. The base has a first locking mechanism and a concave inner surface that conforms with an ultrasound probe. The flexible strap has a first end coupled to the base and a second free end coupled to the base with the first locking mechanism. The bracket is slidably disposed in a slotted region in the base. The needle guide bracket is configured to receive a biopsy needle guide and the needle guide bracket is slidably disposed in a slotted region in the bracket. Other locking mechanisms permit or prevent movement of the bracket relative to the base as well as movement of the needle guide bracket relative to the bracket.

A particulate lyophilized platelet lysate composition suitable for use as a cell culture medium can include growth factors, cytokines, and chemokines released from lysis of source platelets, wherein cellular debris from the source platelets is removed (partially or fully) by filtration. The growth factors, cytokines, and chemokines are lyophilized to form a particulate lyophilized platelet lysate composition.

A shallow water anchor to anchor a water craft in a shallow body of water comprising an anchor positioning assembly mounted on or to the water craft and an anchor member, the anchor position assembly comprises at least one anchor engaging member coupled to an anchor positioning device to raise and lower the anchor member between an elevated position and an anchored position and a system control to control the operation of the anchor position assembly in raising and lowering the anchor member such that the anchor member is lowered to engage the bottom of the shallow body of water to anchor the water craft and the anchor member disengages the bottom of the shallow body of water when the anchor member is raised to permit the water craft to move about the shallow body of water.

The present disclosure is drawn to compositions and methods of making and using lyophilized platelet lysates. Specifically, a method of preparing a composition suitable for therapeutic use or as a culture medium can comprise steps of concentrating platelets from a platelet source to form a platelet rich portion of the platelet source, and lysing the platelets in the platelet rich portion to form a plurality of lysates. An additional step includes lyophilizing the lysates to form lyophilized platelet lysates in a composition with released concentrations of available growth factors, cytokines, and chemokines. In one example, at 30%, by platelet count, of platelets from a platelet source can be lysed using this process.

A surgical clamp assembly includes a clamp having movable jaws, each of which has a clamping surface for engaging a portion of a patient's body. An electrode forms a portion of the clamping surface of at least one of the jaws, the electrode being capable of heating, severing, or cauterizing the portion of the patient's body that is grasped by the clamp. If desired, the clamp assembly can be provided with a retainer that prevents the jaws from being opened accidently. The clamp assembly also can include an actuator that can be detached from the clamp and removed from the operative site, leaving the locked clamp in place. In this type of assembly, when it is desired to remove the clamp, the actuator can be reattached to the clamp and used to disengage the toothed retainer, and thereafter can be used to spread the jaws in order to permit the clamp to be removed.
摘要:
An efficient network formation technique for mobile ad-hoc wireless networks according to the present invention overcomes bandwidth overhead due to generation of database update or Link State Advertisement (LSA) messages in response to changes in certain parameters (e.g., node group size, etc.) with respect to both single and plural node group scenarios. The present invention controls flooding of LSA messages triggered by changes in these parameters (e.g., node group size), thereby reducing overhead traffic during network start-up. This is achieved without impact on message delivery capability and group merge operations. After network start-up is complete and the network is formed, the present invention continues to reduce LSA flooding in a mobile scenario when radios or nodes move into and out of range with one another.
