    摘要: The invention relates to sensing compositional information about material by measuring thermal properties of the material. In one arrangement there is provided a needle probe for sensing compositional information. The probe comprises a needle (2) having a tip region. A resistive element (5) is attached to the needle at the tip region. A measurement system is configured to: 1) drive an electrical current through the resistive element to apply heating to the resistive element, and 2) measure an electrical response of the resistive element to the heating. A processing unit analyses the measured electrical response of the resistive element to the heating to determine compositional information about material in contact with the tip region.

    摘要: In various examples, a stimulation needle apparatus is used for selectively administering a trial stimulation to body tissue of a patient. The stimulation needle apparatus includes a cannula assembly including a cannula and a cannula hub disposed at a proximal cannula end. A stylet assembly includes a stylet sized and shaped to fit within a cannula lumen. A stylet hub is disposed at the proximal stylet end and is configured to engage with the cannula hub. With the stylet hub engaged with the cannula hub, the distal stylet end extends distally from the distal cannula end. A stylet connection is electrically coupled with the stylet and is configured to electrically couple with a stimulator device, such that, a stimulation pulse delivered by the stimulator device is conducted from the stylet connection through the stylet to the distal stylet end to administer the trial stimulation.

    摘要: A pair of cooperating catheters are used together to provide rapid access to the Left heart for diagnostic or therapeutic interventions. The initial entry point for the catheter pair is the groin. The pair of catheters can be used to carry out an electrographic determination of the location of the Fossa Ovalis on the septum. Features on the Catheter system permit quick and reliable confirmation of the catheter location via echo or x-rays. Once across the septum the inner catheter is removed from the outer catheter and a standard intervention may be carried out through the lumen of the outer catheter.

    摘要: The present invention relates to instruments and methods related to the in vivo analytical performance of percutaneously implanted, nitric oxide (NO)-releasing amperometric glucose biosensors. Needle-type glucose biosensors can be functionalized with NO-releasing polyurethane coatings designed to release similar total amounts of NO for rapid or slower (greater than 3 day) durations and remain functional as outer glucose sensor membranes. Relative to controls, NO-releasing sensors were characterized with improved numerical accuracy on days 1 and 3. Furthermore, the clinical accuracy and sensitivity of rapid NO-releasing sensors were superior to control and slower NO-releasing sensors at both 1 and 3 days implantation. In contrast, the slower, extended NO releasing-sensors were characterized by shorter sensor lag times ( 5.8 min) at 3, 7, and 10 d. Collectively, these results highlight the potential for NO release to enhance the analytical utility of in vivo glucose biosensors. Thus, the analytical performance benefit is dependent on the NO-release duration.
