Bi-lateral catheter system and methods for use

The present disclosure provides an apparatus including: (a) a frame having a first end and a second end, wherein the frame includes a plurality of struts arranged between the first end and the second end of the frame, (b) a plurality of channels disposed within the plurality of struts of the frame, (c) an infusion balloon coupled to the frame and arranged such that, in an expanded condition, the frame provides a plurality of openings that the infusion balloon is configured to expand through and extend radially outward from the frame, thereby defining a plurality of grooves, (d) a plurality of holes defined in the frame and configured to permit fluid communication between the plurality of channels and the plurality of grooves, and (e) an infusion hub arranged at the first end or the second end of the frame including a reservoir in fluid communication with the plurality of channels.

Infusion balloon and methods for use thereof

A system for determining peripheral artery disease and method of use for determining the presence or absence of peripheral vascular disease and the severity of the disease in particular vascular segments. The System for determining peripheral artery disease and method of use includes a continuous wave Doppler transceiver which generates a digitized version of quadrature detected stereo audio and is coupleable to a waveform converter and processor. The waveform converter and processor provides filtering, time domain to frequency domain conversion, gain control, and statistical processing of the converted Doppler Stereo audio and is operationally coupled to a display for presenting results to a technician.

The present disclosure provides a wearable garment comprising (a) a sheath having a first end and a second, wherein the sheath defines a cavity in a wearable position, wherein the sheath has a first opening at the first end, and wherein the sheath comprises a first material, and (b) one or more relief zones coupled to the sheath, wherein the relief zones comprise a second material, wherein a pressure distribution of the second material is greater than a pressure distribution of the first material.

Contact point reduction garment

A method of preparing antimicrobial material sheets suitable for manufacturing a wide range of products having antimicrobial properties. In exemplary embodiments, a fabric having antimicrobial agents may be calendered with a polymer such as a silicone compound or an elastomer, in order to create a fused material sheet that contains the antibacterial properties of the fabric. In exemplary embodiments, the antimicrobial agent is copper, a copper alloy, silver, a silver alloy, or other suitable antimicrobial agent from which a fabric may be created. In some exemplary embodiments, an uncured silicone composition and copper alloy fabric are calendered to obtain an antimicrobial material sheet suitable for compression molding a wide range of products. In some exemplary embodiments, an uncured silicone composition and copper alloy fabric are calendered and roto-cured to obtain a cured antimicrobial material sheet or sheet rolls that maybe suitable for die-cutting.
