Abstract: In general, the disclosure relates to medical devices and systems for detecting the posture state of patient. For example, a medical system may detect a posture state of a patient and deliver therapy based at least in part on the detected patient posture state. In some examples, the system may comprise a posture sensor that generates posture sensor data when a patient is in a posture state, and a processor that receives the first posture sensor data, compares the first posture state data to reference posture sensor data, and detects the presence of at least one of sensor signal drift or sensor signal shift for the posture sensor based at least in part on the comparison. In some examples, the processor may be configured to determine one or more offset correction values to apply to posture sensor data generated by the posture sensor when the at least one of sensor signal drift or sensor signal shift is determined to be present.

Abstract: Methods for monitoring patient parameters and blood fluid removal system parameters include identifying those system parameters that result in improved patient parameters or in worsened patent parameters. By comparing the patient's current parameters to past parameters in response to system parameters or changes in system parameters, a blood fluid removal system may be able to avoid future use of parameters that may harm the patient and may be able to learn which parameters are likely to be most effective in treating the patient in a blood fluid removal session.

Abstract: A method for delivering therapy in a medical device includes a two-tiered approach of determining the presence of a lead-related condition, and determining, in response to a lead-related condition being present, the presence of oversensing. Delivery of therapy by the medical device is controlled in response to determining that both the lead-related condition and oversensing are present.

Abstract: An implantable medical device (IMD) is implanted in a patient. The IMD uses a plurality of electrode vectors to generate intrathoracic impedance measurements. The intrathoracic impedance measurements can be indicative of amounts of intrathoracic fluid in the patient. An accumulation of intrathoracic fluid may indicate that the patient is at an increased risk of experiencing a heart failure event in the near future. The IMD performs a vector selection operation on a recurring basis. When the IMD performs the vector selection operation, the IMD uses impedance measurements to select one of the electrode vectors. The IMD can perform a risk assessment operation on another recurring basis. During performance of the risk assessment operation, the IMD uses impedance measurements of the selected electrode vector and/or other patient characteristics stored within the IMD to determine whether the patient is at an increased risk of experiencing a heart failure event.

Abstract: This disclosure is directed to extra, intra, and transvascular medical lead placement techniques for arranging medical leads and electrical stimulation and/or sensing electrodes proximate nerve tissue within a patient.

Abstract: Tissue and other body structures may be protected using a hydrated composition made from free-flowing substantially collagen-free rehydratable polysaccharide particles and rehydratable polysaccharide sponges. Rehydration of the particles without clumping may be carried out be dispersing the particles in a biocompatible water-miscible polar dispersant such as ethanol and combining the dispersion with sufficient aqueous solvent for the particles to convert them to a cohesive hydrogel. The hydrated composition may assist in returning an injured, inflamed or surgically repaired surface to a normal state, e.g., through one or more healing mechanisms such as modulation of an inflammatory response, phagocytosis, mucosal remodeling, reciliation or other full or partial restoration of normal function.

Abstract: A delivery system for use with a prosthetic heart valve having a stent frame to which a valve structure is attached, includes a shaft assembly including a distal end and a coupling structure disposed near the distal end and configured to be coupled to a distal end of the prosthetic heart valve. The system includes a sheath assembly defining a lumen sized to slidably receive the shaft assembly.

The coupling structure is configured to provide a controlled expansion or contraction of the distal end of the prosthetic heart valve based on longitudinal movement of the distal end of the shaft assembly.

As an example, the IMD may monitor a status of one or more inputs of the IMD and adjust the delivery cycle of the electrical stimulation applied to the patient based on the status of the input(s).

In some examples, a method may include acquiring first patient data, wherein the first patient data comprises at least one of first posture state data indicative of a plurality of posture states of a patient during a first time period or first therapy adjustment data indicative of a plurality of patient therapy adjustments made during the first time period; generating baseline patient information based at least in part on the first patient data; and comparing the baseline patient information to patient information generated based on second patient data. Therapy is not delivered to the patient according to a detected posture state of the patient during the first time period, and therapy is delivered to the patient according to the detected posture state of the patient during the second time period.

Abstract: A method of seating a fluid reservoir in a housing of a fluid infusion device is presented here. The method is performed prior to establishing an outgoing fluid flow path from the fluid reservoir. The method begins by detecting insertion of the fluid reservoir into the housing of the fluid infusion device. In response to detecting the insertion, the method determines whether the fluid reservoir is in need of depressurization. When the fluid reservoir is in need of depressurization, the drive motor assembly of the fluid infusion device is rewound to depressurize the fluid reservoir. After depressurizing the fluid reservoir, an equalization state for the fluid reservoir is achieved. After achieving the equilibrium state, the drive motor assembly is advanced to obtain an initial seated state for the fluid reservoir.

When the helical structure is in the expanded configuration, a laterally offset tip portion extends distally therefrom.
