摘要:
Disclosed herein are methods, devices, compositions, and systems for providing an interface between medical instrumentation and a patient. In various embodiments, the interface provides a sterile barrier, acoustic coupler, and thermal insulator between the patient and a medical instrument. In some embodiments, an acoustic coupler interface is used between an ultrasound instrument and a patient. In some embodiments, the acoustic coupler comprises a thermoplastic elastomer (“TPE”) and in particular oil-enhanced or gelatinous TPEs that can be used in diagnostic and therapeutic (HIFU) ultrasound procedures.

A method to deliver focused ultrasound energy from a position outside a skin of a patient to a nerve surrounding a blood vessel, includes placing the patient on a table in a substantially flat position, moving a transducer into a position inferior to ribs, superior to an iliac crest, and lateral to a spine of the patient, maintaining the transducer at the position relative to the patient, and delivering focused ultrasound energy through the skin of the patient without traversing bone, wherein the direction of the focused ultrasound is directed from a lower torso to an upper torso of the patient.

A targeting catheter is used to locate an arteriotomy, such as is formed during a femoral artery catheterization procedure. The targeting catheter includes one or more targeting aids, such as an inflatable balloon or sensor (e.g., Doppler or temperature sensor), to locate the arteriotomy. The targeting aid may be positioned at the arteriotomy. An ultrasonic beacon on the catheter may then be located relative to a therapeutic ultrasonic applicator (e.g., by using acoustic time-of-flight) so that the focus of ultrasonic energy from the applicator can be aligned with the arteriotomy.
摘要:
Systems and methods for sealing a vascular opening such as an arteriotomy formed during a femoral artery catheterization procedure are described. The blood vessel is transiently occluded during application of therapeutic energy, such as high intensity focused ultrasound. The occlusion improves the efficiency of the therapy without causing damage to the blood vessel. Also described are methods for locating the arteriotomy, aligning the therapeutic applicator to the arteriotomy, and a station keeping procedure for maintaining alignment.

摘要:
A dolly capable of allowing relatively heavy and bulky objects to be easily manipulated and moved without adding significantly to the dimension of the object thereby allowing the object to be easily moved through conventional door openings. Preferably, the dolly comprises a first frame having generally vertical legs mechanically coupled to a generally horizontal brace and a second frame having generally vertical legs mechanically coupled to a generally horizontal brace such that the first frame and the second frame are in position on opposite sides of the object and the generally horizontal braces are positioned under corresponding edges of the object. The generally vertical legs of the first frame and the second frame when moved into a more vertical orientation operate to mechanically lift the generally horizontal braces to lift the object and allow the object to be transported to a desired location.
摘要:
The present disclosure provides for a recording device for creating an enhanced personalized image product. The recording device can include a display unit having a graphical user interface. The recording device can comprise a first camera and a second camera simultaneously recording a first image and a second image in a first person perspective and a second person perspective (or another first person perspective), respectively. A unit controller can be operatively coupled to the display unit and the recording unit. The unit controller can comprise a processor and a memory operatively coupled to the processor. The unit controller can be programmed to cause the recorded images to be generated on the display unit. The unit controller and the graphical user interface can allow a user to view the recorded images of the person and edit the recorded images on a single display unit.
摘要:
A filter for filtering radio frequency (RF) power transmitted from an electrostatic chuck (ESC) in a plasma processing system. The plasma processing system may include a heating element disposed at the ESC. The plasma processing system may further include a power supply. The filter may include a core member and a cable wound around and wound along the core member to form a set of inductors. The cable may include a plurality of wires, including a first wire and a second wire, a portion of the first wire and a portion of the second wire being twisted together, a first end of the first wire and a first end of the second wire being connected to the heating element, each of a second end of the first wire and a second end of the second wire being connected to a capacitor and being connected to the power supply.
摘要:
Methods of reducing the permeability of a subterranean formation to aqueous-based fluids using a water-soluble relative permeability modifier that comprises a hydrophobically modified polymer, wherein the hydrophobically modified polymer is a reaction product of: a hydrophilic polymer that comprises a polymer selected from the group consisting of a polyvinylamine, a poly(vinylamine/vinyl alcohol), and an alkyl acrylate polymer; and, a hydrophobic compound comprising at least one alkyl chain having a carbon chain length between about 4 and about 22 carbons. The water-soluble relative permeability modifier may be placed within a subterranean drilling operation such that the water-soluble relative permeability modifier attaches onto surfaces within the subterranean formation to effect permeability of aqueous fluids.
摘要:
A method and apparatus for automating hub and spoke network trouble diagnostics in a communication network are disclosed. For example, the method retrieves provisioning and configuration data, access interface alarm information, and network facility status data related to the communication network by a diagnostic system, and identifies at least one of: a network configuration error, an access interface error, or a configuration error associated with at least one hub router or at least one spoke router, as the root cause of the problem of the communication network.
