Abstract:
A cervical dilation reading apparatus and method of use to accurately and precisely determine cervical dilation measurements during labor and delivery. The apparatus includes a measuring device having a length with a first portion, a second portion and a third portion, a fixed attachment configured to couple with a first finger and fixedly engage the first portion of the measuring device, a slidable attachment configured to couple with a second finger and slidably engage the measuring device along the length between the first and second portions, and a locking mechanism coupled to the glove configured to engage the third portion and lock a length of the measuring device in a substantially extended state when the slidable attachment is slid or moved away from the fixed attachment to record a cervical dilation measurement, and/or a retention mechanism coupled to the glove configured to engage the third portion and retain it near the glove. The method includes providing a cervical dilation reading apparatus, inserting the first and second fingers into the vaginal introitus and locating the cervix and cervical os, placing the first finger on a first side of the cervical os and extending the second finger away from the first finger to a second side, opposite the first side, of the cervical os, thereby extending the length of the measuring device between the first and second fingers to a substantially extended state, locking the length of the measuring device in the substantially extended state with the locking mechanism, if one is present, removing the first and second fingers, and determining a diameter of the cervical os by the length of the measuring device in the substantially extended state between the fixed attachment and slidable attachment.
Abstract:
Methods to generate luminal organ profiles using impedance. One embodiment of such a method comprises the steps of introducing an impedance device having at least two detection electrodes positioned in between at least two excitation electrodes into a treatment site of a luminal organ at a first position, measuring a first treatment site conductance at the first position using the impedance device and at least two injections of solutions having different conductivities, moving the impedance device to a second position in the luminal organ, measuring a second treatment site conductance at the second position using the impedance device and the at least two injections of solutions having different conductivities, calculating a first position cross-sectional area using the first treatment site conductance and a second position cross-sectional area using the second treatment site conductance, and constructing a profile of the treatment site.
Abstract:
A device (1) for monitoring the transverse cross-section of a gastric sleeve (3) as the gastric sleeve (3) is being formed in a stomach (4) during a sleeve gastrectomy procedure comprises a catheter (15) with a primary balloon (19) located thereon towards a distal end (17). The primary balloon (19) is located in the stomach, and the portion of the stomach which is to form the gastric sleeve (3) is stretched around the primary balloon (19) when the primary balloon (19) has been inflated to a diameter approximating to the diameter to which the sleeve (3) is to be formed. As the stomach (4) is being sutured to form the sleeve (3) the pressure within the primary balloon (19) is monitored to avoid excessive stretching of the stomach around the primary balloon (19). The diameter of the primary balloon (19) is also monitored to avoid necking of the sleeve (3) during suturing of the stomach (4).
Abstract:
A 3D scanner for recording topographic characteristics of a surface of at least part of a body orifice, where the 3D scanner includes a main body having a mounting portion; a tip which can be mounted onto and un-mounted from the mounting portion, where the tip is configured for being brought into proximity of the body orifice surface when recording the topographic characteristics such that at least one optical element of the tip is at least partly exposed to the environment in the body orifice during the recording; and a heater for heating the optical element, where the heat is provided by way of thermal conduction; where the tip can be sterilized in a steam autoclave when un-mounted from the main body of the 3D scanner such that it subsequently can be reused.
Abstract:
An endoscopic apparatus is disclosed. The endoscopic apparatus includes a light source which has a plurality of light source components which output light beams which cross one another; an estimator which estimates a geometry of an internal surface of a body; and a controller which controls so that an intensity of a light beam output by any one of the plurality of light source components is variably adjusted based on the estimated geometry of the internal surface of the body.
Abstract:
Systems and methods are provided herein that generally involve measuring a prostate or other object. In some embodiments, a membrane can be sealed over a digit extension to form a closed volume. The closed volume can be inflated via an inflation tube, and a reference pattern can be disposed within the closed volume along with a measurement assembly. In use, a user can put on the glove, position the membrane in proximity to a rectal wall overlying a prostate, and inflate the membrane. As the user slides their finger across the rectal wall, optical fibers in the measurement assembly can move relative to a reference pattern, and a controller can sense light reflected through the fibers from the reference pattern. The controller can calculate or estimate various attributes of the prostate based on the reflected light, such as the palpable surface width or volume.
Abstract:
In one embodiment, a device for measuring a length of a bone tunnel is provided. The device includes: a gauge comprising an annular shaft coupled to a handle, the handle including a constrained channel configured for receiving a passing pin from the annular shaft and displaying the passing pin in relation to a scale. In another embodiment, a method for measuring length of the bone tunnel is provided. A method and another device are provided.
Abstract:
Apparatus and methods for determining a type of a material in a region within a vascular system of a patient and/or a distance to the material are provided. At least one source fiber is provided that supplies light from a light source to a region within a vascular system of a patient. At least one return fiber is provided to receive light reflected from the region within the vascular system. At least one controller is provided to determine at least one property of the region within the vascular system from the reflected light, and to determine a type of a material in the region within the vascular system and/or an indication of a distance to the material. Techniques such as laser ablation may then be performed based on the determined material type and/or distance to remove unwanted buildup, deposits, etc., while avoiding harmful results such as tearing of tissue.
Abstract:
A joint replacement balancing system which provides real-time feedback to a surgeon during a joint replacement surgery to assist the surgeon to balance a joint replacement. The joint replacement balancing system includes a non-transitory processor-readable medium storing code representing instructions to cause a processor to receive a signal from a joint balancing apparatus, determine if the joint replacement is out of balance, determine a corrective course of action to bring the joint into balance and generate and display to the surgeon during the joint replacement surgery a recommended corrective course of action to complete the joint replacement surgery.
Abstract:
A guide member facilitates a device swap for brachytherapy treatment. A cavity evaluation device is introduced during surgery such that a distal end of the device is disposed in a resected cavity of the patient. The cavity evaluation device includes a shaft in which is disposed an elongated guide member. In a subsequent out-patient procedure the cavity evaluation device is removed from the resected cavity. If a brachytherapy treatment is to be performed then the cavity evaluation device is removed without removing the elongated guide member such that position of a portion of the elongated guide member in the resected cavity is maintained relative to the resected cavity. An anchor member helps to maintain the position of the guide member. Introduction of a brachytherapy catheter is then facilitated by introducing the elongated guide member into an opening of the brachytherapy catheter and using the elongated guide member to guide the brachytherapy catheter to the resected cavity.
