Appl. No.:

17/630785

Inventors:

- Ithaca NY, US
Simon Dunham - New York NY, US
Bobak Mosadegh - New York NY, US

International Classification:

A61M 25/00
A61M 25/10

Abstract:

A catheter system is provided that reduces the risk of catheter-associated urinary tract infections by preventing bacteria near the urethral opening from being carried by the catheter during insertion, and by allowing cycling (filling and emptying) of the bladder. The system includes a main lumen, and a balloon near a distal end thereof that is inflatable, after insertion, to open an eyelet to the main lumen that allows urine to flow from the bladder into the main lumen. A catheter system with two balloons, e.g., a retention and an actuation balloon, is also provided herein. An access port at a proximal end has a resting configuration that closes the proximal end of main lumen to prevent drainage of urine through the main lumen. An access cap is provided that, when installed in the access port, opens the access port to allow urine to flow therethrough.

Abstract:

The present disclosure describes a device that can be implanted into the left atrial appendage for occlusion. The device can prevent or reduce thrombus formation in this anatomic region for patients with atrial fibrillation. This device includes a patient-specific inflatable device that represents a patient's anatomy or morphological class. The inflatable device can be designed by imaging (e.g., computed tomography, magnetic resonance imaging) the patient's anatomy. Through a catheter (or surgically), the inflatable device can be filled with an inflation fluid to occlude the appendage in a patient-specific fashion.

Abstract:

The present disclosure describes a system and a method for producing patient-specific small diameter vascular grafts (SDVG) for coronary artery bypass graft (CABG) surgery. In some embodiments, the method for producing SDVGs includes non-invasive quantification of patient-specific coronary and vascular physiology by applying computational fluid dynamics (CFD), rapid prototyping, and in vitro techniques to medical images and coupling the quantified patient-specific coronary and vascular physiology from the CFD to computational fluid-structure interactions and SDVG structural factors to design a patient-specific SDVG.

Abstract:

The present disclosure describes a system that can enable the prediction of coronary flow without invasive medical procedure. The system can generate physical models that can provide an accurate assessment of coronary mechanics and enable realistic simulation of coronary procedures. The models can enable the hemodynamic measurement of flow through the model and the study of flow dynamics through the model and the biomechanics of the model.

International Classification:

A61B 34/10
A61B 90/00
A61B 34/20

Abstract:

The systems and method described herein can generate guidance images that can indicate the real-time position of a medical device within an anatomical target. For example, the images can be high-resolution, 3D holographic renderings of a catheter (an example medical device) within a patient's heart (an example anatomical target). The guidance system can generate images that include computer generated (CG) images or models of the medical device and target anatomy. The guidance system can generate the CG images of the target anatomy from pre-operative images of a first modality, such as CT images or MR images. The guidance system can determine real-time placement position of the medical device from an intra-operative image of a second modality, such as fluoroscopic images.

A61B 5/0215
G01L 11/04

Abstract:

Systems and method to measure pressure are described herein. The system can include a force sensor can that be implanted into a patient to measure, for example, cardiac pressure. The force sensor can include first and second film layers that can define a plurality of pressure cells. An external pressure can deform the pressure cells and change their resonant frequency. When exposed to an acoustic signal, the pressure cells can resonant at a pressure-dependent resonant frequency. The system can detect reflected acoustic waves generated by the resonance of the pressure cells. The system can convert the frequency readings into pressure values.

International Classification:

A61B 17/12

Abstract:

Systems and methods for occluding a body cavity including providing an implantable void-filling device, wherein the implantable void-filling device includes an inflatable implant that defines an interior of the implantable void-filling device. The inflatable implant is capable of being filled with an inflation material to cause the inflatable implant to expand from a collapsed configuration to an expanded configuration. The implantable void-filling device also includes a connection hub attached to an exterior surface of the inflatable implant and a plurality of independent anchors coupled to and extending out from the connection hub along the length of the inflatable implant, such that the plurality of anchors collectively surround the inflatable implant. The connection hub and anchors are configured such that expansion of the anchors away from the surface of the inflatable implant anchors the void filling device to a body tissue.
