摘要： A probe cap for use with an ultrasound probe including a head portion and an acoustic surface is disclosed. In one embodiment, the probe cap includes a body that defines a cavity sized for releasably receiving the head portion of the probe therein. The probe cap body further defines a hole that is proximate the acoustic surface of the head portion. A compliant spacer component is disposed in the hole. The spacer component can include a hydrogel and provides an acoustic path between the acoustic surface and a tissue surface of a patient. The spacer component includes a skin contact surface that defines a concavity and is deformable against the tissue surface. Additional embodiments disclose various probe cap and accompanying needle guide designs for use in assisting a clinician with ultrasound probe use and needle insertion into a patient.

摘要： A dilator system for insertion of a catheter or other elongate device into a body of a patient includes a catheter having a lumen that initially defines a first inner diameter. The catheter includes a swellable material that swells after insertion into the body. A dilator includes an elongate body that is initially disposed in the catheter lumen and a tapered head extending from a distal end of the catheter lumen. The dilator head defines an outer diameter that is larger than the first inner diameter of the catheter lumen. After insertion of the dilator head and a distal portion of the catheter into the body, the catheter swells such that the lumen defines a second inner diameter that is larger than the outer diameter of the dilator head. This enables the dilator to be proximally removed from the body via the catheter lumen defining the second diameter.
摘要翻译：用于将导管或其他细长装置插入患者体内的扩张器系统包括具有初始限定第一内径的内腔的导管。导管包括在插入体内后膨胀的可膨胀材料。扩张器包括最初设置在导管内腔中的细长主体和从导管内腔的远端延伸的锥形头部。扩张器头限定出比导管内腔的第一内径大的外径。在将扩张器头部和导管的远端部分插入体内后，导管膨胀使得内腔限定比扩张器头部的外径大的第二内径。这使得扩张器能够通过限定第二直径的导管腔向近端移除。

摘要： A catheter tube for insertion into a body of a patient is disclosed. The catheter tube includes a distal portion that remains stable during fluid infusion into the patient, thus reducing or eliminating whipping of the catheter distal tip, even during power injection. In one embodiment, the catheter tube defines at least one lumen and is formed from a tube material that defines a proximal portion and a distal portion of the catheter tube. The catheter tube is configured such that the arithmetic product of an elastic modulus and an area moment of inertia for at least a portion of the distal portion of the catheter tube defined by the catheter tube material is greater relative the arithmetic product of an elastic modulus and an area moment of inertia for at least a portion of the proximal portion of the catheter tube.

摘要： A medical device is disclosed comprising a diaphragm having at least one slit valve disposed therein, and a valve housing configured to secure the diaphragm at a peripheral portion of the diaphragm, wherein a central portion of the diaphragm is positioned relative to the peripheral portion of the diaphragm such that compressive forces acting on the peripheral portion of the diaphragm create moment forces which bias the slit valve in a closed position. A method is disclosed for using the device in connection with a catheter for regulation of fluids to and from a patient.

摘要： A clamp for selectively compressing a portion of tubing, such as an extension leg of a PICC or other catheter, is disclosed. The clamp is able to be opened or closed with a thumb and finger of a single hand of a user and is slidably attached to the tubing so as to enable its placement as desired along the tube. In one embodiment, the tubing clamp comprises a body including first and second body portions hingedly connected to one another in a clamshell configuration, a latch for releasably latching the first and second body portions together, and at least two tube compression members. The tube compression members cooperate to compress and occlude a portion of tubing passing through the tubing clamp when the first and second body portions are latched to one another.
