Embodiments herein relate to medical devices including electric field shaping leads and methods for using the same to treat cancerous tumors within a bodily tissue. In an embodiment, an implantable lead for a cancer treatment system is disclosed. The lead can include a lead body having a proximal end and a distal end, where the lead body can define a lumen. The lead can also include a paddle disposed at the distal end of the lead body, the paddle having a width that is greater than a width of the lead body. The paddle can include one or more electrodes disposed on the paddle and one or more electrical conductors disposed within the lumen of the lead body to provide electrical communication between the one or more electrodes and the proximal end of the lead body. Other embodiments are also included herein.

A filter cartridge for a surgical gas delivery system is disclosed which includes a housing having a front end and a rear end and defining a first interior flow path extending downstream from a first inlet at the rear end of the housing to a first outlet at the front end of the housing, and a second interior flow path extending upstream from a second inlet at the front end the housing to a second outlet at the rear end of the housing, a first pleated filter element operatively associated with the first interior flow path, a second pleated filter element operatively associated with the second interior flow path, and a carbon filter disc operatively associated with the second interior flow path and positioned adjacent a downstream side of the second pleated filter element.

Filter cartridge assemblies

Catheter and implantable leadless pacing devices, systems, and methods utilizing catheters and implantable leadless pacing devices are disclosed. An example catheter system may include a holding structure extending distally from a tubular member. An implantable device, such a leadless pacing device, may be located within a cavity of the holding structure and an electrical barrier may be located within the holding structure at a location between a proximal electrode and a distal electrode of the implantable device. The electrical barrier may inhibit electrical signals of the implantable device from traveling within the holding structure between the proximal electrode and the distal electrode of the implantable device. The holding structure may include one or more electrical ports adjacent the proximal end of the holding structure and adjacent or proximal of the proximal electrode of the implantable device.

A system for performing an endoscopic surgical procedure in a surgical cavity of a patient that includes a multi-lumen tube set including a dual lumen portion having a pressurized gas line and a return gas line for facilitating gas recirculation relative to the surgical cavity of the patient, and a single lumen portion having a gas supply and sensing line for delivering insufflation gas to the surgical cavity of the patient and for periodically sensing pressure within the surgical cavity of the patient, a first gas sealed single lumen access port communicating with the dual lumen portion of the tube set and a second valve sealed single lumen access port communicating with the single lumen portion of the tube set.

Separable two-part single lumen gas sealed access port for use during endoscopic surgical procedures

An implantable medical device (IMD) is configured with a pressure sensor. The IMD includes a housing and a diaphragm that is exposed to the environment outside of the housing. The diaphragm is configured to transmit a pressure from the environment outside of the housing to a piezoelectric membrane. In response, the piezoelectric membrane generates a voltage and/or a current, which is representative of a pressure change applied to the housing diaphragm. In some cases, only changes in pressure over time are used, not absolute or gauge pressures.

Systems and methods for implantable medical devices and headers are described. In an example, an implantable medical device includes a device container including an electronic module within the device container. A modular header core includes a first core module including a first bore hole portion of a first bore hole, the first bore hole portion configured to couple a first electrical component with the electronic module. A second core module includes a second bore hole portion of a second bore hole different than the first bore hole, the second bore hole portion configured to couple a second electrical component with the electronic module. The first core module is detachably engaged with the second core module. A header shell is disposed around the modular header core and attached to the device container.

This document discusses, among other things, systems and methods to determine an indication of contractility of a heart of a patient using received physiologic information, and to determine blood pressure information of the patient using the heart sound information and the determined indication of contractility of the heart. The system can include an assessment circuit configured to determine an indication of contractility of a heart of the patient using first heart sound (S) information of the patient, and to determine blood pressure information of the patient using second heart sound (S) information of the patient and the determined indication of contractility of the heart.

Chronic monitoring of blood pressure using heart sounds

A system is disclosed for performing an endoscopic surgical procedure in a surgical cavity, which includes a multi-modal gas delivery device including a primary gas circulation pump, a secondary gas circulation pump and an insufflation subunit, and an interface plate adapted and configured to engage with the multi-modal gas delivery device and including a connector and a filter seat corresponding to five different lumens, each of which provides a different functionality.

Systems and methods for monitoring patients with respiratory diseases are described. A system may include a sensor circuit configured to sense one or more physiological signals indicative of respiratory sounds, and a spectral analyzer to generate first and second spectral contents at respective first and second frequency bands. The system may produce a respiratory anomaly indicator using the first and second spectral contents, or additionally with other physiological parameters. The system may detect an onset or progression of a target respiratory condition such as asthma or chronic obstructive pulmonary disease using the respiratory anomaly indicator, or to trigger or adjust a therapy.
