Pulsatile balloon catheter systems are provided. Aspects of the systems include: a pulse generator; and a balloon catheter assembly operably connected to the pulse generator. In embodiments, the balloon catheter assembly includes: a proximal connector operably connecting the balloon catheter assembly to the pulse generator and configured to transduce a first pulse energy generated by the pulse generator to a second pulse energy; a distal balloon; and a catheter component, where the catheter component includes a fluidic passage operably positioned between the proximal connector and the distal balloon, which passage is configured to propagate the second pulse energy from the proximal connector along the fluid passage to the distal balloon. Also provided are balloon catheter assemblies and kits that include the same. Also provided are systems and methods for assessing vessel compliance in-vivo. Also provided are systems and methods for determining system state of balloon catheter systems. The systems, assemblies and kits find use in a variety of different applications, including balloon angioplasty applications.

A tourniquet for occluding blood flow to a limb is improved by the addition of proximal and distal strain gauges. The proximal strain gauge may be monitored under conditions of total blood flow occlusion for time-varying signals indicative of volumetric limb changes arising from the subject's blood flow in the proximal section of the limb. Upon a change in limb occlusion pressure, the signals from the proximal strain gauge can be observed to change also, and the working pressure in the tourniquet can be adjusted safely in response. Automated control systems may further use inputs from a distal strain gauge and/or from a sensor that detects induced pressure changes within the tourniquet to improve the control of the tourniquet working pressure during operation to avoid unwanted blood flow past the tourniquet.

A sample collection device for collecting a fluid sample is provided. The device includes a sample collection chamber, for collecting a sample therein, having a first end and a second end and a sample collection conduit, for conveying a sample from a user into the sample collection chamber. The sample collection conduit includes an inlet for receiving a sample and wherein in at least a first position the sample collection conduit extends from within the sample collection chamber out through the first end such that at least the inlet is outside of the sample collection chamber. The device further includes a plunger configured to expel the sample out of the sample collection chamber through the second end of the sample collection chamber.

A surgical device for reducing visceral fat in the abdominal cavity comprises an elongate shaft and an inflatable member. The inflatable member comprises a small-profile deflated configuration for being advanced into the abdominal cavity and a large-profile inflated configuration comprising a planar distal treatment surface for treating the visceral fat. The thermal fluid, preferably a gas, is circulated through the inflatable member at a temperature range sufficient to cause cryolipolysis to the fat cells but not damage non-target tissues. The inflatable member can have several chambers, reinforcing members, and ports to provide controlled flow patterns that maintain the shape of the inflatable member when inflated.

Disclosed herein is a stone removing apparatus and a stone size measuring method, which can take a picture of a stone and measure the size of the stone in order to stably remove the stone without damaging a human body. The stone removing apparatus includes: an insertion tube having an inner space; a guide tube inserted into the inner space of the insertion tube to be moved; a wire inserted into the guide tube to be movable; a basket disposed at the front of the wire to grasp a stone; an imaging unit disposed at the front end of the guide tube in order to take an image of a stone grasped by the basket; and a control unit electrically connected with the imaging part to analyze the image taken by the imaging unit, wherein the control unit calculates a distance between the imaging unit and the basket to measure the actual size of the stone using the calculated distance.

A parturition drape (100) includes a drape (101) and a twin pouch assembly (102). The twin pouch assembly defines a first pouch (1101) and a second pouch (1301) attached to a major face of the drape. A flap (103) is attached to the major face of the drape. The flap (103) is selectively insertable into an open end of either the first pouch or the second pouch.

A female insertion system is provided. The system includes a conformable insert shaped for insertion into one or more structures of a female human that are associated with at least one of reproduction and one or more erogenous zones; one or more sensors, at least one of the sensors included in the insert, and configured to measure and to relay data, wherein the data is acquired on one of a one-time basis and a multiple-time basis included one of a non-continuous period, a continuous period, and an intermittent temporal period; and a processor configured to: control the insert; generate a treatment for one of the structures of the female human; store the data; and based on the data, automatically affect one or more of the structures via the insert.

A Doppler ultrasound system for executing Doppler ultrasound tests. The Doppler ultrasound system employs an ultrasound probe (40), a vessel FORS sensor (20) and a Doppler ultrasound controller (60). In operation, an ultrasound probe (40) transmits an ultrasound beam through a bodily vessel (e.g., a blood vessel) for generating imaging data illustrative of an ultrasound image of fluid flow through the bodily vessel (e.g., blood flow through a blood vessel), and the vessel FORS sensor (20) is introduced into the bodily vessel for generating vessel sensing data informative of a reconstructed shape of the vessel FORS sensor (20) within the bodily vessel relative to the ultrasound probe (40). Responsive to the data, the Doppler ultrasound controller (60) estimates a parametric relationship between the fluid flow through the bodily vessel and a transmission by the ultrasound probe (40) of the ultrasound beam through the bodily vessel.
